The fact that several half-grabens and normal faults developed in the Lower--Middle Cambrian of Tazhong （central Tarim Basin） and Bachu areas in Tarim Basin, northwest China, indicates that Tarim Basin was under extensional tectonic setting at this time. The half-grabens occur within a linear zone and the normal faults are arranged in en echelon patterns with gradually increasing displacement eastward. Extensional tectonics resulted in the formation of a passive continental margin in the southwest and a cratonic margin depression in the east, and most importantly, influenced the development of a three- pronged rift in the northeast margin of the Tarim Basin. The fault system controlled the development of platform -- slope -- bathyal facies sedimentation of mainly limestone-dolomite-gypsum rock-saline rock-red beds in the half-grabens. The NW-SE trending half-grabens reflect the distribution of buried basement faults.

Diverse and abundant microfossils, such as palynomorphs, algae and Ostracoda, were collected from lower Cretaceous strata of Lishu depression, located in southeastern Songliao basin, and were identified and classified in order to provide relevant, detailed records for paleoclimate research. The early Creta- ceous vegetation and climate of southeastern Songliao basin have been inferred from the analysis of palynomorph genera, algae and Ostracoda of the LSI and SW110 wells. The lower Cretaceous strata include, in ascending stratigraphic order, the Shahezi, Yingcheng and Denglouku formations. Palyno- logical assemblages for each formation, based on biostratigraphic and statistical analyses, provide an assessment of their longitudinal variations. During deposition of the Shahezi Formation, the climate was mid-subtropical. Vegetation consisted of coniferous forest and herbage. During deposition of the Ying- cheng Formation, the climate was south Asian tropical. Vegetation consisted mainly of coniferous forest and herbal shrub. In addition, fresh and saline non-marine water dominated the lacustrine setting during deposition of these formations. Deposition of the Denglouku Formation, however, occurred under a hot and dry tropical climate. The vegetation was mostly coniferous forest and lake waters became saline. Palaeoclimate variation is correlated by the lake level change and the development of sedimentary facies. Palaeoclimate contribute to the formation of hydrocarbon source rocks and reservoir.

This paper establishes a theoretical model of the single-compressor-driven (SCD) three-stage Stirlingtype pulse tube cryocooler (SPTC) and conducts experimental verifications. The main differences between the SCD type and the multi-compressor-driven (MCD) crycooler are analyzed, such as the distribution of the input acoustic power in each stage and the optimization of the operating parameters, in which both advantages and difficulties of the former are stressed. The effects of the dynamic temperatures are considered to improve the accuracy of the simulation at very low temperatures, and a specific simulation example aiming at 10 K is given in which quantitative analyses are provided. A SCD threestage SPTC is developed based on the theoretical analyses and with a total input acoustic power of 371.58 W, which reaches a no-load temperature of 8.82 K and can simultaneously achieve the cooling capacities of 2.4 W at 70 K, 0.17 W at 25 K, and 0.05 W at 10 K. The performance of the SCD three-stage SPTC is slightly poorer than that of its MCD counterpart developed in the same laboratory, but the advantages of lightweight and compactness make the former more attractive to practical applications.

The combination patterns and depositional characteristics of the carbonate banks are investigated based on outcrop sections, thin sections, and carbon isotopes of Ordovician in the western Tarim Basin, China. Four carbonate bank combination patterns are deposited in the Ordovician, western Tarim Basin, including： Reef-Bank Complex （RBC）, Algae-Reef-Bank Interbed （ARBI）, Thick-Layer Cake Aggradation Bank （TLCAB）, and Thin-Layer Cake Retrogradation Bank （TLCRB）. All combination patterns show clear periods vertically. The RBC is mainly composed of reefs and bioclastic banks, and the dimension of the RBC depends on the scale of the reefs. Bioclastic banks deposits surround the reefs. The range of the ARBI is determined by the scale of algae-reefs, algae peloid dolomite microfacies and algal dolomite microfacies deposit alternating vertically. TLCAB and TLCRB are deposited as layer-cakes stacking in cycles and extending widely with cross bedding developed. The grains of TLCAB and TLCRB are diverse and multi-source. With the impacting of relative sea level change, biological development and geomorphology, the ARBI, TLCAB or TLCRB, RBC are successively developed from the Lower Ordovician Penglaiba Formation to the Middle Ordovician Yijianfang Formation. The depositional environment analysis of Ordovician indicates that the RBC and ARBI can form effective oil and gas reservoirs, and the TLCAB and TLCRB have the potential to form the huge scale oil and gas reservoirs and to be the crucial targets of exploration for the Ordovician carbonate banks in the future.

我国深层海相碳酸盐具有埋藏深度大、地质时代老、地质演化过程复杂等特点,其储层形成和分布受到众多因素制约,是海相油气勘探面临的关键问题之一。本文总结了团队在塔里木盆地长期研究成果,从深层碳酸盐岩建造和改造作用出发,揭示塔里木盆地多类型碳酸盐岩储层的主要发育条件和有序性分布。(1)塔里木盆地台地格局、地层发育演化及后期的埋藏与改造,均是盆缘构造事件在盆内的构造-沉积作用响应。早古生代盆地经历了地貌张裂分化与小型裂陷群形成、地貌挤压分化与层间不整合发育、古隆起与大型不整合作用、多期不整合叠加与古隆起埋藏改造等演化过程。(2)碳酸盐岩台地沉积过程中存在着不同尺度、不同类型的分异演化作用,可分为雏形期、建造期、鼎盛期和分解-消亡期,相应的台地边缘演化经历了缓斜坡、进积镶边、加积镶边和退积陡坡等建造过程,控制着台缘礁滩、台内滩、早期白云岩化潮坪等有利于规模化储集岩发育的沉积相带分布。(3)多级次不整合和断裂-流体改造是优质储层形成的重要机制。多期区域构造活动和周期性海平面变化控制了不同级别的不整合面发育,海平面下降主导的层序界面导致碳酸盐岩周期性暴露,形成了不同规模的层间岩溶和同沉积岩溶,区域构造运动所对应的大型不整合控制了大规模表生岩溶储层发育,不同规模的断裂和裂缝既是储层发育带,也是流体活动和改造的主要区带。(4)塔北-顺北地区不整合发育强度和断裂活动强度由北向南有序变化,控制了碳酸盐岩储层类型与分布的有序性变化,自北向南依次发育雅克拉断凸潜山型白云岩储层、塔河主体区古风化壳型岩溶储层、塔河斜坡区层控型岩溶储层、塔河覆盖区断溶型储层和顺北断控型储层,反映出由剥蚀区至覆盖区不整合控储作用逐渐变弱,而断裂控储作用增强。

碳酸盐岩次生溶蚀孔洞是优质的储集空间,为油气的运聚提供条件。为研究溶洞发育的控制因素,选取广西东兰-凤山地区石炭纪-二叠纪碳酸盐岩溶蚀特征进行分析。镜下显示,研究区岩石类型为亮晶生屑灰岩、颗粒灰泥灰岩、含颗粒灰泥灰岩、晶粒灰岩和灰泥颗粒灰岩等,孔隙类型主要为粒间溶蚀孔、粒内溶蚀孔、晶间孔和微裂缝。研究发现,影响洞穴发育的主要因素有构造、岩组类型、流体性质、气候及岩溶古地貌。构造控制洞穴发育规模,在构造破碎带及其附近容易发育大规模洞穴;目的层大套灰岩是溶蚀的物质基础,力学强度较大的亮晶生屑灰岩易于形成大型洞穴,当岩石含较多灰泥或发生重结晶时,溶蚀难度增加;酸性流体、温暖潮湿气候和岩溶斜坡地貌,为洞穴发育的有利条件。其中,构造对洞穴发育的控制作用最大。
