摘要: 近两年我国南方川北-鄂西地区上二叠统吴家坪组-大隆组取得了页岩气重大勘探突破,并在中二叠统孤峰组发现了勘探新苗头,但其富有机质层段的分布规律及其页岩气资源潜力仍不清楚. 通过对川北-鄂西地区中二叠统地层开展沉积相识别与层序地层对比划分,分析不同层序的岩相古地理演化特征,进而探讨该区孤峰组富有机质层段的分布规律与页岩气资源潜力. 研究结果表明:川北-鄂西地区中二叠统可划分为3个三级层序SQ1、SQ2和SQ3,其中层序SQ3对应于孤峰组,沉积于卡匹敦晚期;层序SQ3沉积时期,该区在碳酸盐岩台地(对应层序SQ1和SQ2)基础上发育了3个北西向展布的深水盆地,即鄂西盆地、开江-梁平台盆(海槽)和广旺台盆(海槽);孤峰组硅质岩与硅质页岩层段的有机碳TOC含量较高(平均TOC含量为3%~10%),且展布相对连续稳定;峨眉山地幔柱事件驱动了该区中二叠世晚期深水斜坡-盆地环境的形成,从而控制着孤峰组富有机质硅质岩与硅质页岩的大规模区域性沉积....
Deeply buried (>3500 m) marine shale has become a focus point for the future exploration and exploitation of hydrocarbon in China. Low-temperature nitrogen adsorption (LTNA), scanning electron microscopy (SEM), nuclear magnetic resonance (NMR), other experiments were combined to characterize pore structure fluid division deep-marine southern Sichuan Basin this study. The results suggest that had relatively developed nanopore network, especially with honeycomb organic pores. These pores...
Lacustrine shale oil has the potential to lead development of China's and gas industry. By integrating scanning electron microscopy, low-temperature CO 2 N adsorption, high-pressure mercury intrusion, nuclear magnetic resonance with centrifugation at different speeds, pore system fluid distribution Da’anzhai Member lacustrine in Sichuan Basin are studied. The results show that: (1) reservoir space is mainly inorganic pores micro-fractures. Nano-micron scale commonly found widely distributed...
The Upper Permian Linghao Formation shale is the most potential gas exploration target in Nanpanjiang Basin. In this study, X-ray diffraction, field emission scanning electron microscopy, CH4 isothermal adsorption, and nuclear magnetic resonance cryoporometry are intergrated to reveal comprehensive characterization of collected from a well Results indicate that organic-rich shales developed Ling 1 member lower part 3 member. predominantly characterized by kerogen type I, with relatively...
The Lower Permian Shanxi Formation in the Eastern Ordos Basin is a set of transitional shale, and it also key target for shale gas exploration China. Three sets organic-rich intervals (Lower Middle Upper shale) developed Shan 2 3 Submember Formation. Based on TOC test, X-diffraction, porosity, in-situ content experiment NMR experiments with gradient centrifugation drying temperature, reservoir characteristics pore fluid distribution three are studied. results show that: 1) shales have higher...
Based on porosity and permeability tests, high-pressure mercury injection (HPMI), nuclear magnetic resonance (NMR) centrifugal experiments, this study comprehensively analyzed the quality, pore structure fractal characteristics of tight sandstone reservoir in meandering stream facies. The purpose is to reveal relationship between physical properties, geometry topological parameters pores, fluid mobility heterogeneity system reservoirs results show that second member Middle Jurassic Shaximiao...
Abstract Accurate evaluation of gas content is significant for unconventional reservoirs and determination hydrocarbon reserves. Based on nuclear magnetic resonance (NMR) experiment plug samples saturated methane isothermal adsorption crushed samples, the free adsorbed Shanxi Formation transitional shale under high-temperature high-pressure were determined. The experimental results show that maximum theoretical in study area 2.58 cm 3 /g-5.44 /g, mainly composed gas, proportion generally...
Quartz is one of the most abundant minerals in shales, occurring predominantly three forms: biogenic quartz (BQ), detrital (DQ) and clay-transformed (CTQ). The content typically correlated with fracability shale gas reservoirs. However, origins its influence on mechanical properties remain not fully elucidated. To address this gap, study examines samples from LM1-LM8 graptolite zones well W202 Weiyuan field, Sichuan Basin as research object. After systematic analysis organic geochemistry,...
