摘要/Abstract

摘要： 为研究四川盆地石柱地区自流井组页岩气的成藏条件，开展了野外地质露头调查、岩心观察、有机地球化学分析、X射线衍射测试、物性分析和扫描电镜观察等工作。结果表明：①石柱地区自流井组东岳庙段形成于半深湖相，岩性以泥页岩为主，厚度为30～95 m。②目的层泥页岩具有“有机质丰度高、热演化程度适中”等特征，TOC质量分数多为0.49%～2.02%，R_o平均为1.27%，脆性矿物质量分数平均为58.8%。③岩石中吸附气含量较高，质量体积平均为2.78 m³/t，且埋深适中，具有良好的勘探前景。④采用叠合法预测出石柱地区桥头坝—建南—上水坝一带为页岩气勘探的有利区，通过计算可以获得研究区页岩气地质资源量约为3 905亿m³。该研究成果可为四川盆地石柱地区自流井组页岩气勘探提供借鉴。

Abstract: In order to study the shale gas accumulation conditions of Ziliujing Formation in Shizhu area of Sichuan Basin,field geological outcrop survey,core observation,organic geochemical analysis,X-ray diffraction test, physical property analysis and scanning electron microscopy observation were carried out. The results show that:(1)The Dongyuemiao member of Ziliujing Formation in Shizhu area was formed in semi-deep lake facies,and the lithology was dominated by shale with a thickness of 30-95 m.(2)The mudstone of the target zone was characterized by high abundance of organic matter and moderate thermal evolution. The TOC mass fraction is 0.49%-2.02%,the R_o average is 1.27%,and the brittle mineral average is 58.8%.(3)The content of adsorbed gas in rocks is high,the average mass volume is 2.78 m³/t,and the burial depth is moderate,so it has good exploration prospects.(4)The Qiaotouba-Jiannan-Shangshuiba area in Shizhu area was predicted to be a favorable area for shale gas exploration by superimposition method,and the geological resource of shale gas was estimated to be about 390.5 billion m³. The research results can provide reference for shale gas exploration of Ziliujing Formation in Shizhu area,Sichuan Basin.
