【摘要】：通過對綏濱坳陷濱頁1井泥頁巖樣品的巖石熱解分析、族組分分析和色譜分析,系統(tǒng)分析了該井泥頁巖的地球化學(xué)特征。結(jié)果表明:濱頁1井發(fā)育穆棱組、城子河組及東榮組3套泥頁巖層系。泥頁巖有機(jī)質(zhì)豐度較高,各項(xiàng)指標(biāo)綜合評價為中—好烴源巖,有機(jī)質(zhì)類型以Ⅱ2型為主,其次為Ⅱ1型與Ⅲ型。類異戊二烯型烷烴Pr/Ph比值較大,總體位于1.0~3.0之間,為弱氧化環(huán)境。穆棱組與東榮組具甾烷C_(29)優(yōu)勢,代表陸源高等植物生源輸入,城子河組為多源輸入。鏡質(zhì)組反射率、甾烷成熟度、藿烷異構(gòu)體比值均顯示濱頁1井泥頁巖有機(jī)質(zhì)成熟度已達(dá)到成熟階段。綜合地球化學(xué)分析表明,綏濱坳陷泥頁巖具備較好的生烴潛力,具有較好的頁巖氣勘探前景。
[Abstract]:Through the analysis of rock pyrolysis, group composition analysis and chromatographic analysis of shale samples from well Binhui 1 in Suibin Depression, the geochemical characteristics of mud shale in this well are systematically analyzed. The results show that Muling formation is developed in well Binhui 1. There are three sets of shale strata in Chengzihe formation and Dongrong formation. The abundance of organic matter in shale shale is high. The comprehensive evaluation of each index is medium-good hydrocarbon source rock, the type of organic matter is mainly type 鈪，
