【摘要】：通過(guò)野外地質(zhì)調(diào)查資料及樣品測(cè)試分析,結(jié)合前人研究的結(jié)果,對(duì)川東南武隆地區(qū)五峰組—龍馬溪組頁(yè)巖氣形成的基礎(chǔ)地質(zhì)條件進(jìn)行了研究,指出五峰組與龍馬溪組底部富有機(jī)質(zhì)頁(yè)巖形成于深水陸棚環(huán)境,富有機(jī)質(zhì)頁(yè)巖厚度大,分布廣,埋深適中(300~3 500 m),脆性礦物含量較高,TOC主要分布于2%~5%之間,熱演化程度處于高成熟—過(guò)成熟早期階段,發(fā)育溶蝕(微)孔、粒間微孔、粒內(nèi)微孔、有機(jī)質(zhì)孔及微裂縫等,并通過(guò)綜合信息疊合分析,提出了5個(gè)頁(yè)巖氣富集區(qū)。
[Abstract]:Through the field geological survey data and sample test analysis, combined with the results of previous studies, the basic geological conditions for formation of shale gas in the five peak group of Wulong area, the Long Maxi formation, are studied. It is pointed out that the five peak group and the bottom of the Long Maxi formation are rich in the deep-water shelf environment, and the rich shale is thick and widely distributed. The buried depth is moderate (300~3 500 m), the content of brittle minerals is high, and TOC is mainly distributed between 2%~5%. The thermal evolution is in the early stage of high maturity and over maturity, and the dissolution (micro) pores, intergranular micropores, micropores, organic pores and micro cracks are developed, and 5 shale gas enrichment areas have been put forward through comprehensive information overlap analysis.
