The commercial exploitation of unconventional petroleum resources (e.g., shale oil/gas and tight oil/gas) has drastically changed the global energy structure within past two decades. Sweet-spot intervals (areas), most prolific hydrocarbon resources, generally consist extraordinarily high organic matter (EHOM) deposits or closely associated sandstones/carbonate rocks. formation sweet-spot (areas) is fundamentally controlled by their depositional subsequent diagenetic settings, which result...
The Bilong Co oil shale is one of the most significant source rocks in Mesozoic Qiangtang Basin (Northern Tibet); however, its absolute chronology remains controversial. In this study, situ carbonate U–Pb isotope dating analysis was carried out for first time. Detailed field geological investigations yielded some age-diagnostic ammonites, enabling a re-evaluation stratigraphic age shale. A total 61 spots from middle part section suggests an average 181 ± 13 Ma. Elemental geochemistry and...
Abstract The Guanwushan Formation of Middle Devonian in Sichuan Basin is an excellent oil and gas reservoir, but its genetic mechanism still unclear, previous studies mainly focus on the typical profile northwest Sichuan. In this paper, characteristics genesis dolomite are studied by taking Jiguanshan section southwest as example. Chongzhou City located middle Longmen Mountain Chengdu. Through field measurement, petrological observation, isotope analysis, REE distribution mode fluid...
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....
The Late Ordovician mass extinction (LOME, ca. 445 Ma; Hirnantian stage) is the second most severe biological crisis of entire Phanerozoic. LOME has been subdivided into two pulses (intervals), at beginning and ending glaciation, LOMEI-1 LOMEI-2, respectively. Although studies suggest a rapid cooling and/or oceanic euxinia as major causes for this extinction, driver these environmental changes still debated. As other Phanerozoic's extinctions, extensive volcanism may have potential trigger...
