The North Sea Basin is the most important oil and gas producing area in Europe and the birthplace of many classic petroleum geological theories. From the perspective of multi-spheric interactions in the Earth, this study investigated the riftforeland-rift evolution process of the North Sea Basin, which was controlled by the deep dynamic driving forces of the continental collision orogeny, mantle plume uplift, and intraplate deformation. The North Sea Basin was found to have drifted northward since the Carboniferous and passed through the low-latitude Hadley and the mid-latitude Ferrel cells. Two sets of main hydrocarbon source rocks have formed, the coals and coal measures of the Upper Carboniferous Westphalian and the marine shale of the Upper Jurassic Kimmeridge Clay Formation. We propose that the deep processes, tectonic activity, and transgression-climate evolution jointly controlled the types and horizons of the source rocks, reservoirs, and seals in different regions of the North Sea Basin. In the southern North Sea Basin, a Carboniferous-Lower Triassic gas-rich petroleum system was formed,which is characterized by transitional coal measure source rocks, desert aeolian sandstone reservoirs, and evaporite cap rocks. In the northern North Sea Basin, an Upper Triassic-Paleogene oil-rich petroleum system was formed, which is characterized by marine graben-type source rocks, deltaic sandstone and marine limestone reservoirs, and marine tight marl and shale cap *** late tectonic burial and uplift in the North Sea Basin further controlled the processes of oil and gas generation and accumulation, ultimately leading to a differential distribution pattern which is oil rich in the northern part and gas rich in the southern part of the basin. In the future, there is an urgent need to re-examine the mechanisms for the petroleum generation and accumulation in large mature exploration areas(e.g., super basins such as the North Sea) and low exploration areas(e.g., the O

An igneous intrusion of 94m thick was discovered intruding into the Silurian sandstone from Tazhong 18 Well. The petroleum previously preserved in the Silurian sandstone reservoir was altered into black carbonaceous bitumen by abnormally high heat stress induced by the igneous intrusion. The reflec-tance of the carbonaceous bitumen reaches as high as 3.54%, indicating that the bitumen had evolved into a high thermal evolution level. Similar to the Silurian samples from the neighboring Tazhong 11, Tazhong 12. Tazhong 45 and Tazhong 47 wells, the distribution of C2., C2. and C2. steranes of the car-bonaceous bitumen is still "V" -shaped and can still be employed as an efficient parameter in oil source correlation. The "V" -shaped distribution indicates that the hydrocarbons from the Tazhong 18 and the neighboring wells were all generated from the Middle-Upper Ordovician hydrocarbon source rocks. However, the oil source correlation parameters associated with and terpanes had been changed greatly by the high heat stress and can no longer be used in oil source correlation. The δ 13C values of the pe-troleum from the neighboring wells are between -32.53‰ and -33.37‰, coincident with those of the Paleozoic marine petroleum in the Tarim Basin. However, the δ 13C values of the carbonaceous bitumen from the Tazhong 18 Well are between -2..18‰ and -2..2.‰, isotopically much heavier than the pe-troleum from the neighboring wells. The content of light hydrocarbons (nC14-nC2.) of the saturated hydrocarbon fraction in the carbonaceous bitumen is extremely higher than the content of heavy hy-drocarbons. The light/heavy hydrocarbon ratios (ΣnC2.-/ΣnC2.+) are between 4.56 and 39.17. In the saturated fraction, the even numbered hydrocarbons are predominant to the odd numbered, and the OEP (Odd to Even Predominance) values are between 0.2. and 0.49. However, the content of light hy-drocarbons in the petroleum from the neighboring wells is relatively low and the content of the even numb

Currently， significant hurdles lie ahead in china’s lacustrine shale oil exploration and exploitation， particularly due to the high clay mineral content， which severely impacts pore development in organic-rich shales. In this study， we take the medium- to high-maturity shale of the Qingshankou Formation (K2.n) in the Gulong Sag， Songliao Basin， china， as an example and analyze the dynamic evolution of the clay minerals and their effects on pore development by core observations， scanning electron microscopy， X-ray diffraction， physical property and nitrogen adsorptions to provide a valuable reference for the effective evaluation of lacustrine clay-rich shale oil reservoirs. Our findings reveal that the dynamic transformation of clay minerals in the Qingshankou Formation is classified into three stages based on diagenesis， thermal maturity， and mineral characteristics: the initial stage (vitrinite reflectivity (Ro) 1.3%). Clay minerals play crucial roles in controlling shale reservoirs during the rapid transformation process， which is evidenced by the formation of shrinkage fractures， enhanced pore connectivity， increased porosity， and expanded space for shale oil adsorption and storage. In addition， authigenic quartz can form during the transformation of clay minerals， contributing to increased reservoir brittleness and improving the potential for reservoir fracturing.

Understanding the acoustic characteristics of hydrates in various sediments is crucial for hydrate resource detection and safe and efficient exploitation, as hydrate occurrence patterns vary greatly in different sediments. In this work, sediments with different bentonite contents, water saturations, and types were prepared to investigate the characteristics of P-wave velocity(reflecting the magnitude of hydrate saturation in the sediment) and amplitude(reflecting the degree of hydrate-sediment cementation) during hydrate formation and depressurization. During hydrate formation, the P-wave velocity and amplitude have similar trends. As clay content increases, the P-wave velocity increase rates quickened. On the other hand, the increased rate of P-wave velocity slows down with the increase of water saturation in the clay-bearing sediments. Comparing various types of sediment shows that the water absorption and swelling of bentonite reduce the pore space, speeding up the cementation of the hydrate with the sediment and increasing P-wave velocity at a faster rate. Correspondence between P-wave velocity and hydrate saturation is strongly related to sediment type, clay content, and water *** rapidly decreasing amplitude in the early stage of hydrate depressurization indicates that hydrate in clay-bearing sediments is weakly cemented to the sediments, which is prone to stratigraphic *** findings of this study offer guidance for hydrate resource assessments in clay-bearing sediments as well as geologic risk estimations during hydrate mining.

探究富有机质泥页岩孔隙结构的划分方案、前沿表征方法、演化及发育影响因素,对页岩油储量评价及商业开发具有指导意义。通过调研富有机质泥页岩孔隙结构研究进展,归纳孔隙的划分方案,对比不同现代测试手段在泥页岩孔隙结构表征过程中的优劣性,探讨海、陆相泥页岩孔隙结构的演化模式和有机、无机孔隙发育的主控因素,展望富有机质泥页岩孔隙研究未来的发展趋势。结果表明:(1)泥页岩储层表征的手段主要可以划分为成像法、流体侵入法、吸附法、散射法四类。(2.红外连用的原子力显微镜(AFM-IR)能够揭示泥页岩中显微组分的化学和岩石力学非均质性,小角中子散射(SANS)、核磁共振(NMR)和纳米CT技术是揭示孔隙连通性的重要途径。(3)沉积环境控制着泥页岩岩相和有机质母质来源,成岩和生烃作用及其相互间影响是泥页岩孔隙演化的主控因素,海、陆相泥页岩孔隙演化随时间和深度总体上均有“减孔→增孔→减孔→增孔→减孔”的规律,但陆相泥页岩在未熟-成熟阶段孔隙变化得更频繁。(4)Ⅰ型干酪根的有机质孔发育潜力远高于Ⅲ型干酪根,强生烃能力的腐泥组显微组分可发育丰富的有机孔隙,液态烃运移之后经二次裂解形成的焦沥青能提供更有效的连续性渗透路径。(5)成岩过程中无机矿物间的相互转化,长石、碳酸盐岩等矿物差异性溶蚀,压实、压溶和胶结作用等均会复杂化无机孔隙网络,有机-无机相互作用及矿物自身的岩石力学性质也是无机孔隙发育的重要影响因素。岩心在地表和地下所处环境差异巨大,未来的研究需要建立一个页岩孔隙在地面与地层条件下的反馈机制和矫正机制,进一步还原页岩油气在地下孔隙结构中真实的赋存状态。

Discovered in S15 and some other wells, the Lower Ordovician in the northern Tarim Basin consists mainly of brown gray-dark gray very fine-fine crystalline dolomite, with a minor portion of locally light gray-white medium-coarse crystalline dolomite. Silicification can be observed in the medium-coarse dolomite, and some euhedral drusy quartz can also be found in pores and fractures of the dolomite. The homogenization temperature of the fluid inclusions in the medium-coarse dolomite is between 110 and 2.0°C with maximum between 140 and 190°C, and the salinity is between 10.7 and 18.5 wt.% NaCl Eq. The homogenization temperature and salinity of the fluid inclusions in the medium-coarse dolomite are similar to those in the drusy quartz. Compared with the very fine-fine dolomite, the medium-coarse phase contains relatively high Fe and Mn. The average concentration of FeO and MnO in the medium-coarse dolomite is 1.917% and 0.32.%, respectively. The medium-coarse dolomite has a remarkable negative Eu anomaly, consistent with the REE pattern of the intermediate-felsic igneous rocks in the Tarim Basin. The oxygen isotopic composition of the medium-coarse dolomite is relatively lighter than that of the very fine-fine dolomite. The δ18OPDB values of the medium-coarse dolomite are between -10.35‰ and -7.31‰. The δ18OSMOW values of the fluid associated with the medium-coarse dolomite can be calculated according to homogenization temperature and oxygen isotope fractionation factor between dolomite and fluid, and the calculated values are between +4‰ and +10‰, consistent with those of the hydrothermal fluid. The medium-coarse dolomite has relatively high 87Sr/86Sr ratios as well, indi- cating an origin associated with intermediate-felsic igneous rock. The homogenization temperature, element composition, REE pattern, oxygen and strontium isotopes demonstrate that the medium-coarse dolomite is the result of recrystallization of very fine-fine dolomite under hydrothermal environment
