The Upper Triassic oil accumulations in the Ordos Basin is the most successful tight oil play in China,with average porosity values of less than 10% and permeability values below 1.0 *** study investigated the geological characteristics and origin of the tight oil accumulations in the Chang 6 member of the Upper Triassic Yanchang Formation in the Shanbei area based on over 50,000 petrological,source-rock analysis,well logging and production *** tight oil accumulation of the Chang 6 member is distributed continuously in the basin slope and the centre of the *** oilwater relationships are *** dissolution pores are the most important storage spaces,constituting 30%-60% of total porosity and showing a strong positive relationship with oil *** pore-throat diameter is less than 1 μm,and the calculated critical height of the oil column is much larger than the tight sand thickness,suggesting that the buoyancy was probably of limited importance for oil *** pressure difference between the source rocks and sandstone reservoirs is inferred to have provided driving force for hydrocarbon *** factors of source-reservoir configuration and laumontite dissolution contributed to the formation of the Chang 6 tight oil *** hydrocarbon generation and continuous sand bodies close to the hydrocarbon kitchen are the foundation for the large-scale oil *** of feldspar-laumontite during the process of organic matter evolution generated abundant secondary pores and improved the reservoir quality.

Shale gas is one of the most promising unconventional resources both in China and abroad. It is known as a form of self-contained source-reservoir system with large and continuous dimensions. Through years of considerable exploration efforts, China has identified three large shale gas fields in the ruling, Changning and Weiyuan areas of the Sichuan Basin, and has announced more than 540 billion m3 of proven shale gas reserves in marine shale systems. The geological theories for shale gas development have progressed rapidly in China as well. For example, the new depositional patterns have been introduced for deciphering the paleogeography and sedimentary systems of the Wufeng shale and Longmaxi shale in the Sichuan Basin. The shale gas storage mechanism has been widely accepted as differing from conventional natural gas in that it is adsorbed on organic matter or a mineral surface or occurs as free gas trapped in pores and fractures of the shale. Significant advances in the techniques of microstructural characterization have provided new insights on how gas molecules are stored in micro- and nano-scale porous shales. Furthermore, newly-developed concepts and practices in the petroleum industry, such as hydraulic fracturing, microseismic monitoring and multiwell horizontal drilling, have made the production of this unevenly distributed but promising unconventional natural gas a reality. China has 10-36 trillion m3 of promising shale gas among the world＇s whole predicted technically recoverable reserves of 206.6 trillion m3. China is on the way to achieving its goal of an annual yield of 30-50 billion m3 by launching more trials within shale gas projects.

鄂尔多斯盆地延长组7段富含大量页岩油,但由于对页岩与泥岩特征差异缺乏深入了解,阻碍了该层系页岩油的有效开发。为此,采用岩心观察、薄片鉴定等直接观察手段与XRD、Rock-Eval、TOC、氯仿沥青"A"抽提、主微量元素等实验相结合,对研究区长7段页岩和泥岩的岩石学、矿物学、有机地球化学与无机地球化学特征进行了深入研究。结果表明:长7段页岩的颜色较深,发育明显页理,切面光滑,而泥岩不具有纹层和页理,断口不整齐且切面粗糙;页岩的有机质以顺层富集为主,泥岩有机质以分散赋存为主;页岩的粘土矿物含量较高,泥岩的石英含量较高;页岩的TOC平均值为18.5%,约为泥岩的5倍,生烃潜量是泥岩的5~8倍;氯仿沥青"A"组分对比显示页岩含较多的芳烃,泥岩则含有较多的饱和烃;页岩沉积水体的盐度相对泥岩略低,且水深相对较浅。长7段页岩呈西北-东南走向分布,厚度主要为15~30 m,与泥岩呈互补式分布。页岩油"源内聚集"的特点使长7段的页岩油宏观分布受到页岩相控制。开展泥岩与页岩的对比研究,对准确预测富有机质页岩分布及指导页岩油气勘探具有重要意义。

泥质岩可分为泥岩和页岩两大类,二者在成因机制、有机质含量及赋存状态、矿物组成等方面存在显著差异。开展湖相泥岩、页岩的分布特征研究以及其差异特征的对比,有助于建立富有机质页岩的沉积模式。鄂尔多斯盆地三叠系延长组7段(长7段)沉积时期为湖盆发展的鼎盛时期,湖盆中心沉积了大套的泥岩和页岩。该文应用典型剖面分析、岩心-薄片观察、地球化学分析等手段揭示了长7段泥岩和页岩在分布特征、地球化学特征、岩石组分、组构、主微量元素等五方面的差异。(1)分布特征:泥岩和页岩互补分布,泥岩主要发育在三角洲前缘、深湖-浊积岩相和半深湖相,页岩主要沉积于深湖相;(2)组构特征:页岩有页理,有机质顺层分布,泥岩无页理,有机质分散分布;(3)岩石组分:页岩更富集黄铁矿,是泥岩的11倍,泥岩的白云岩、菱铁矿含量更高;(4)有机地球化学指标:页岩TOC平均含量为6.6%,是泥岩的3倍,S1值平均含量为3.1 mg/g,是泥岩的2.5倍;(5)主微量元素:页岩中U,Th,Mo,Co,Ni等微量元素显著高于泥岩且U/Th,V/Cr和P/Al的比值较高,泥岩中Ti/Al和K/Al比值更高。综合分析,鄂尔多斯盆地长7泥岩和页岩的形成主要受沉积相带、湖水深度和湖盆生产力控制。页岩沉积时,水体生产力更高,离物源更远,水体更为缺氧。

探讨鄂尔多斯盆地上三叠统长7段致密油有效烃源岩的主控地质因素及分布特征。结合地质异常理论,采用因子分析、痕量元素分析、趋势面分析及标准化处理等技术手段,提出一种对研究区长7段烃源岩进行地质数据挖掘与信息整合的评价方法,建立表征烃源岩品质的综合性无因次线性组合,揭示出在有机碳丰度普遍较高的背景下,有效烃源岩的发育主要受控于低等水生生物勃发(有机质类型指数)与有机质热演化程度(镜质体反射率)。有效烃源岩集中分布于姬塬南部、定边西部、油房庄东部、华池地区及合水东北部,对致密油高产富集带的分布具有一定的控制作用。有利于进一步提高长7段致密油勘探开发成效的地区主要是耿湾-环县、华池北部、油房庄-吴仓堡及定边。

Based on the typical dissection of various onshore tight oil fields in China,the tight oil migration and accumulation mechanism and enrichment-controlling factors in continental lake basins are analyzed through nuclear magnetic resonance(NMR)displacement physical simulation and Lattice Boltzmann numerical simulation by using the samples of source rock,reservoir rock and crude *** continental lake basins,the dynamic forces driving hydrocarbon generation and expulsion of high-quality source rocks are the foundational power that determines the charging efficiency and accumulation effect of tight oil,the oil migration resistance is a key element that influences the charging efficiency and accumulation effect of tight oil,and the coupling of charging force with pore-throat resistance in tight reservoir controls the tight oil accumulation and sweet spot *** degree of tight oil enrichment in continental lake basins is controlled by four factors:source rock,reservoir pore-throat size,anisotropy of reservoir structure,and *** high-quality source rocks control the near-source distribution of tight oil,reservoir physical properties and pore-throat size are positively correlated with the degree of tight oil enrichment,the anisotropy of reservoir structure reveals that the parallel migration rate is the highest,and intralayer fractures can improve the migration and accumulation efficiency and the oil saturation.
