【摘要】：為了對淮南地區(qū)煤系烴源巖特征作出評價(jià),在采集相關(guān)樣品的基礎(chǔ)上對淮南煤田下石盒子組泥頁巖樣品的礦物特征和有機(jī)質(zhì)的含量、顯微組成以及成熟度進(jìn)行了測試。結(jié)果表明:下石盒子組泥頁巖中石英含量在35%左右;黏土礦物含量均值為56.28%。有機(jī)碳平均含量1.21%;干酪根以Ⅲ型和近于Ⅲ的Ⅱ2型為主,利于生氣;樣品的鏡質(zhì)組反射率均大于0.7%;生烴峰溫基本高于445℃,有機(jī)質(zhì)已進(jìn)入成熟階段。此外,多層煤層或煤線也為生烴提供了物質(zhì)基礎(chǔ)。綜合評價(jià)認(rèn)為,下石盒子組的烴源巖具有良好的生烴潛力,但較高的黏土礦物含量可能對后期的開采帶來不利影響。
[Abstract]:In order to evaluate the source rock characteristics of coal series in Huainan area, the mineral characteristics, organic matter content, microstructure and maturity of shale samples of Xiashihezi formation in Huainan coalfield were tested on the basis of collecting relevant samples. The results show that the content of quartz in shales of Xiashihezi formation is about 35%, and the average content of clay is 56.28%. The average organic carbon content was 1.21; the kerogen was mainly type 鈪，
