【摘要】：對(duì)渝東北城口地區(qū)下寒武統(tǒng)魯家坪組頁(yè)巖的地球化學(xué)特征、巖石礦物學(xué)特征、儲(chǔ)集層物性特征、儲(chǔ)集空間特征、含氣性和保存條件以及頁(yè)巖含氣性的影響因素進(jìn)行了分析后認(rèn)為,研究區(qū)魯家坪組頁(yè)巖保存條件良好,有機(jī)質(zhì)含量高,成熟度高,干酪根以Ⅰ型為主,頁(yè)巖脆性高;儲(chǔ)集空間以礦物粒間孔隙為主,儲(chǔ)集層大孔較發(fā)育,單位吸附氣量大,但由于渝東北城口地區(qū)魯家坪組地層結(jié)構(gòu)復(fù)雜,有機(jī)質(zhì)成熟度過(guò)高,這些不利因素可能會(huì)加大后期開(kāi)發(fā)的難度。
[Abstract]:The geochemical characteristics, petromineralogical characteristics, reservoir physical properties and reservoir spatial characteristics of the Lower Cambrian Lujiaping formation shale in Chengkou area, northeastern Chongqing, are discussed. It is concluded that the shale of Lujiaping formation in the study area has good preservation conditions, high organic matter content, high maturity, high kerogen type 鈪，
