【摘要】：我國(guó)海相頁巖氣的勘探開發(fā)已經(jīng)取得了一定的進(jìn)展,相比之下,煤系頁巖氣研究成果較少。本文以貴州鳳岡區(qū)的海相頁巖和沁水盆地的煤系頁巖為例,通過干酪根類型、總有機(jī)碳含量、礦物組成和孔隙結(jié)構(gòu)等四方面進(jìn)行儲(chǔ)層特性對(duì)比,分析海相頁巖氣儲(chǔ)層和煤系頁巖氣儲(chǔ)層差異,查明不同沉積環(huán)境下頁巖氣儲(chǔ)層特點(diǎn),為煤系頁巖氣的進(jìn)一步勘探開發(fā)奠定基礎(chǔ)。研究結(jié)果表明兩者既有相似又有所區(qū)別:海相頁巖和煤系頁巖干酪根類型存在明顯差異,前者以Ⅰ型、Ⅱ型干酪根為主,后者主要為Ⅲ型干酪根;海相頁巖總有機(jī)碳含量和脆性礦物含量較煤系頁巖高;兩者均發(fā)育有機(jī)質(zhì)孔,且以中孔(2~50nm)為主,低溫氮?dú)馕角�都為Ⅳ型,但海相頁巖孔隙比表面積較高。加之煤系頁巖單層厚度薄,連續(xù)性差,對(duì)煤系頁巖氣的勘探開發(fā)不能完全照搬海相頁巖氣的開發(fā)模式,可以考慮與煤層氣、致密砂巖氣一起勘探開發(fā),提高資源利用率,實(shí)現(xiàn)經(jīng)濟(jì)開采。
[Abstract]:The exploration and development of marine shale gas in China has made some progress, but the research results of coal shale gas are less. In this paper, the marine shale in Fenggang area, Guizhou Province, and the coal shale in Qinshui basin are taken as examples. The reservoir characteristics are compared in four aspects: kerogen type, total organic carbon content, mineral composition and pore structure. The difference between marine shale gas reservoir and coal measure shale gas reservoir is analyzed, and the characteristics of shale gas reservoir under different sedimentary environment are identified, which lays a foundation for further exploration and development of coal measure shale gas. The results show that there are similarities and differences between the two types: there are obvious differences between marine shale and coal-measure shale kerogen types, the former is mainly type 鈪，
