The India–Eurasia collision has produced a number of Cenozoic deep intracontinental basins,which bear important information for revealing the far-afield responses to the remote collision.Despite their significance,their subsiding mechanism remains the subject of debate,with end-member models attributing it to either orogenic or sedimentary load.In this study,we conduct flexural subsidence modeling with a two-dimensional finite elastic plate model on the Hotan-Mazatagh section along the southern Tarim Basin,which defines a key region in the foreland of the West Kunlun Orogen,along the NW margin of the Tibetan Plateau.The modeling results indicate that the orogenic load of West Kunlun triggers the southern Tarim Basin to subside by up to less than ~6 km,with its impact weakening towards the basin interiors until ~230 km north from the Karakax fault.The sedimentary load,consisting of Cenozoic strata,forces the basin to subside by ~2 to~7 km.In combination with the retreat of the proto-Paratethys Sea and the paleogeographic reorganization of the Tarim Basin,we propose that surface processes,in particular a shift from an exorheic to an endorheic drainage system associated with the consequent thick sedimentary load,played a decisive role in forming deep intracontinental basins in the context of the India-Eurasia collision.

According to the capillary theory,an equivalent capillary model of micro-resistivity imaging logging was built.On this basis,the theoretical models of porosity spectrum(Ф_(i)),permeability spectrum(K_(i))and equivalent capillary pressure curve(pe)were established to reflect the reservoir heterogeneity.To promote the application of the theoretical models,the Archie's equation was introduced to establish a general model for quantitatively characterizing bi,K,and pei.Compared with the existing models,it is shown that:(1)the existing porosity spectrum model is the same as the general equation of gi;(2)the Ki model can display the permeability spectrum as compared with Purcell's permeability model;(3)the per model is constructed on a theoretical basis and avoids the limitations of existing models that are built only based on the component of porosity spectrum,as compared with the empirical model of capillary pressure curve.The application in the Permian Maokou Formation of Well TsX in the Central Sichuan paleo-uplift shows that the Ф_(i),K_(i),and p_(ci) models can be effectively applied to the identification of reservoir types,calculation of reservoir properties and pore structure parameters,and evaluation of reservoir heterogeneity.

The Palaeozoic carbonate basement of the Offshore Bohai Bay Basin (OBBB) presents considerable potential for hydrocarbon exploration. However, the multistage tectonism and complex superimposed palaeo-karstification in the area are unclear, which leads to a lack of understanding on the formation mechanism and distribution of the deep carbonate basement reservoirs. In this study, the occurrence of a fracture-vug network and its fillings in carbonate reservoirs were investigated based on borehole cores, thin sections, and image logs from the southwestern slope of the OBBB's Bozhong Sag. Then the diagenetic fluid properties of the carbonate matrix and fillings were analysed via the data of carbon, oxygen, and strontium isotopes, and major, rare elements from coring intervals. The results revealed that fracture-related karst reservoirs have lithologic selectivity inclined toward dolomite strata. The intersecting relationships, widths, and strikes of the fractures and the regional tectonic background indicate three structural fracture families: NW-, NNE-, and NNW- trending, related to the Indosinian, middle Yanshanian, and late Yanshanian orogeny, respectively. The Indosinian NW- and end-Mesozoic NNE-trending fractures produced by compressional tectonic stress mainly contributed to the formation of the basement reservoirs. The geochemistry of the calcite veins filling these fractures suggests two main types of diagenetic fluids. The fluid of autogenic recharge related to the earlier fills is karstification diffuse flow dominated by internal runoff from rainfall in the highland setting of the Indosinian thrusting orogenic belt. The other fluid of allogenic recharge related to the later fills is the main lateral freshwater flow dominated by external runoff from the catchment in the setting of the horst-lowland within the rifting basin, induced by the Yanshanian destruction of the North China Craton. Finally, the relationship between the three fracture families and two kinds of related fluids is revealed. This allows us t

In this work,using fractured shale cores,isothermal adsorption experiments and core flooding tests were conducted to investigate the performance of injecting different gases to enhance shale gas recovery and CO_(2)geological storage efficiency under real reservoir conditions.The adsorption process of shale to different gases was in agreement with the extended-Langmuir model,and the adsorption capacity of CO_(2)was the largest,followed by CH_(4),and that of N_(2)was the smallest of the three pure gases.In addition,when the CO_(2)concentration in the mixed gas exceeded 50%,the adsorption capacity of the mixed gas was greater than that of CH4,and had a strong competitive adsorption effect.For the core flooding tests,pure gas injection showed that the breakthrough time of CO_(2)was longer than that of N_(2),and the CH_(4)recovery factor at the breakthrough time(Rch,)was also higher than that of N_(2).The RcH of CO_(2)gas injection was approximately 44.09%,while the RcH,of N_(2)was only 31.63%.For CO_(2)/N_(2)mixed gas injection,with the increase of CO_(2)concentration,the RcH,increased,and the RcH,for mixed gas CO_(2)/N_(2)=8:2 was close to that of pure CO_(2),about 40.24%.Moreover,the breakthrough time of N_(2)in mixed gas was not much different from that when pure N_(2)was injected,while the breakthrough time of CO_(2)was prolonged,which indicated that with the increase of N_(2)concentration in the mixed gas,the breakthrough time of CO_(2)could be extended.Furthermore,an abnormal surge of N_(2)concentration in the produced gas was observed after N_(2)breakthrough.In regards to CO_(2)storage efficiency(S_(Storage-CO_(2)),as the CO_(2)concentration increased,S storage-co_(2)also increased.The S storage-co_(2),of the pure CO_(2)gas injection was about 35.96%,while for mixed gas CO_(2)/N_(2)=8:2,S sorage-co,was about 32.28%.

Plugging technology is one of the leading problems in shale gas drilling engineering,as it causes wellbore stability,shale formation collapse,and so on.In order to solve these problems,in this paper,we committed to preparing artificial cores whose original permeability was 1.16×10^(−4)mD,which could be used to simulate the shale formation,and established a sealing evaluation method to assess the effect of plugging technology by measuring permeability reduction rate K'.Verified the good reproducibility of the artificial cores through a lot of high temperature and high pressure(HTHP)filtration experiments.The Scanning electron microscopy(SEM)was used to prove that the permeability reduction rate is a scientific method to evaluate the sealing effect.

To reveal the development characteristics and distribution of gravity flow sedimentary system under micro-paleogeomorphologic units of the Chang 7 Member of Triassic Yanchang Formation in the southwestern Ordos Basin,on the basis of the restoration of the paleogeomorphological form of the Chang 7 depositional period by the impression method,each micro-paleogeomorphologic unit was depicted in-depth,and the characteristics and development models of gravity flow deposits in the study area were studied in combination with outcrop,core,mud logging and log data.The results show that:(1)The paleogeomorphology in the Chang 7 depositional period was an asymmetrical depression,wide and gentle in the northeast and steep and narrow in the southwest.Three sub-paleogeomorphologic units were developed in the basin,including gentle paleo-slope,paleo-slope and paleo-depression,and they can be further subdivided into eight micro-paleogeomorphologic units:bulge,groove,slope break belt,plain of lake bottom,deep depression of lake bottom,paleo-channel,paleo-ridge of lake bottom,and paleo-uplift of lake bottom.(2)There are 9 types of lithofacies and 4 types of lithofacies assemblages of Chang 7 Member.According to lithofacies composition and lithofacies vertical combination,the gravity flow deposit is further divided into 5 types of microfacies:restricted channel,unrestricted channel,natural levee,inter-channel,lobe.(3)Paleogeomorphology plays an important role in controlling sediment source direction,type and spatial distribution of sedimentary microfacies,genetic types and distribution of sand bodies in Chang 7 Member.

The Ordovician-Silurian Wufeng and Longmaxi Shale in the Sichuan Basin were studied to understand the genesis and diagenetic evolution of carbonate minerals and their effects on reservoir quality. The results of geochemical and petrological analyses show that calcite grains have a negative Ce anomaly indicating they formed in the oxidizing environment of seawater. The high carbonate mineral contents in the margin of basin indicate that calcite grains and cores of dolomite grains appear largely to be of detrital origin. The rhombic rims of dolomite grains and dolomite concretions with the δ^(13)C of –15.46‰ and the enrichment of middle rare earth elements were formed during the sulfate-driven anaerobic oxidation of methane. The calcite in radiolarian were related to the microbial sulfate reduction for the abundant anhedral pyrites and δ^(13)C value of –11.34‰. Calcite veins precipitated in the deep burial stage with homogenization temperature of the inclusions ranging from 146.70 ℃ to 182.90 ℃. The pores in shale are mainly organic matter pores with pore size mainly in the range of 1–20 nm in diameter. Carbonate minerals influence the development of pores through offering storage space for organic matter. When calcite contents ranging from 10% to 20%, calcite grains and cement as rigid framework can preserve primary pores. Subsequently, the thermal cracking of liquid petroleum in primary pores will form organic matter pores. The radiolarian were mostly partially filled with calcite, which combining with microcrystalline quartz preserved a high storage capacity.

Profile control is utilized to redirect the injection water to low permeability region where a large amount of crude oil lies.Performed gel particles are the commonly used agent for redistributing water by blocking the pores in high permeability region.But the capability of deep penetration of performed gel particles is poor.Here,we formulate nanoparticle stabilized emulsion(NSE).The stability and the effect of NSE on the fluid redirection in a three-dimensional porous medium were investigated.By usingμ-PIV(particle image velocimetry),it was found that the velocity gradient of continuous fluid close to the nanoparticle stabilized droplets is much higher than that close to surfactant stabilized droplets.NSE behaves as solid particle in preferential seepage channels,which will decrease effectively the permeability,thereby redirecting the subsequent injection water.Furthermore,NSE shows high stability compared with emulsion stabilized by surfactant in static and dynamic tests.In addition,water flooding tests also confirm that the NSE can significantly reduce the permeability of porous media and redirect the fluid flow.Our results demonstrate NSE owns high potential to act as profile control agent in deep formation.

Formation mechanism of reservoir oolitic dolomite in Lower Triassic Feixianguan formation, northeastern Sichuan Basin, southwest China

Journal of Central South University 2014年第8期21卷 3263-3274页

A series of marine natural gas fields were recently discovered in oolitic dolomites of the Lower Triassic Feixianguan formation,northeastern Sichuan Basin,southwest China.The mechanism forming these reservoir dolomites is debatable,limiting the ability to characterize these reservoir successfully.Based on the investigation of the representative Dukouhe,Luojiazhai,and Puguang areas,this issue was addressed by examining the distribution,petrology,and geochemistry of the dolomites,the most comprehensive study to date was provided.Dolomitization occurred at a very early stage of diagenesis,as shown by the petrological features of the rock fabric.Vadose silt,which is composed primarily of dolomitic clasts,is found in the primary and secondary pores of the oolitic dolomite.This indicates that the overlying strata were subjected to dolomitization when the Feixianguan formation was located in the vadose zone.Therefore,it may be inferred that the dolomitization which occurred before the formation was exposed to meteoric conditions.The spatial distribution and geochemical characteristics of the dolomite indicate that dolomitization occurred as a result of seepage reflux.The degree of dolomitization decreases with increasing distance from the evaporative lagoon.Furthermore,the type and porosity of the dolomite vary in different zones of the upward-shoaling sequence,with the porosity gradually decreasing from the highest layer to the lowest layer.This reflects a close relationship between dolomitization and seawater evaporation during the formation of the dolomite.Geochemical analysis provided further evidence for the relationship between the dolomitization fluid and the coeval seawater.The 87Sr/86 Sr and δ13C isotopes,as well as the abundances of trace elements,Fe and Mn,indicate that seawater concentrated by evaporation acted as the dolomitization fluid.These results also show that dolomitization most likely occurred in a semi-closed diagenetic environment.Therefore,the main mechanism of oolitic dolomite formation is seepa

Fault Development and Tectonic Evolution in the Lishu Depression， Songliao Basin， NE China

引用

Journal of Earth Science 2023年

作者： Shengmin Su Youlu Jiang Yuhu Liu sinopec Northeast oil and gas company School of Geoscience China University of Petroleum (East China) CNOOC Research Institute Ltd.

The Lishu Depression， located in the southeastern region of the Songliao Basin， exhibits diverse fault types and complex tectonic evolution characteristics， however， the slipping direction and activity duration of strike-slip faults， as well as the overall tectonic evolution process remain unknown. This study applied a method for determining the slipping direction and activity duration of strike-slip faults， and reconstructed the tectonic evolution process of the Lishu Depression using balanced cross sections. The determination of the slipping direction of strike-slip faults was based on the analysis of the dislocation distance of a specific set of strata on two fault walls within the anticline zone， and the activity duration of strike-slip faults was defined by the sedimentary period of the strata cut by faults， and the variation characteristics of formation thickness. The slipping direction and activity duration of the strike-slip faults in the study area suggest that the depression experienced a left-lateral strike regime during the sedimentary periods of 135–131.8 and 124.5–112 Ma. However， during the sedimentary periods of the Yingcheng Formation (131.8–124.5 Ma)， the region was influenced by a right-lateral strike background. The study area experienced a continuous process of extension from 145.6 to 124.5 Ma， and compression commenced from the depositional period of the Nenjiang Formation (88.5 Ma)， as shown by negative values of the extension rate. The findings of this study hold significant theoretical implications for the identification of the slipping direction and distance of strike-slip faults within comparable depressions. Moreover， these results have practical implications for further hydrocarbon exploration in the Lishu Depression.
