【摘要】：為確定雷家地區(qū)沙四段致密油烴源巖評價標(biāo)準(zhǔn)及有利勘探區(qū),通過對該區(qū)烴源巖巖性、TOC、有機(jī)質(zhì)成熟度、有機(jī)質(zhì)類型、生烴潛力等指標(biāo)綜合分析,認(rèn)為該區(qū)烴源巖TOC高、成熟度適中,有機(jī)質(zhì)類型好,生油潛力大,確定了該區(qū)沙四段致密油烴源巖優(yōu)質(zhì)源巖巖性主要為碳酸鹽質(zhì)泥頁巖、泥質(zhì)云(灰)巖及黏土型泥頁巖,長英質(zhì)泥頁巖次之,并根據(jù)烴源巖有機(jī)質(zhì)類型、TOC、Ro、ST等指標(biāo)確定Ⅰ、Ⅱ、Ⅲ類烴源巖的評價標(biāo)準(zhǔn)。落實(shí)該區(qū)Ⅰ類烴源巖主要分布于陳家洼陷主體,面積為54.9 km~2;Ⅱ類烴源巖主要分布于陳家洼陷的外緣,面積約為153.0 km~2;Ⅲ類烴源巖主要分布于陳家洼陷的東側(cè),面積約為51.0 km~2。確定該區(qū)致密油Ⅰ類有利勘探區(qū)集中在陳家洼陷內(nèi),Ⅱ類有利勘探區(qū)主要為陳家洼陷的側(cè)緣及北部臺安洼陷主體,Ⅲ類有利勘探區(qū)為陳家洼陷的東側(cè)。該研究對確定下一步有利勘探目標(biāo)具有一定的指導(dǎo)意義。
[Abstract]:In order to determine the evaluation standard and favorable exploration area of tight oil source rocks in the fourth member of Shahejia area, through comprehensive analysis of the lithology of source rocks, maturity of organic matter, types of organic matter, hydrocarbon generation potential and so on, it is concluded that the source rocks in this area are of high TOC. The maturity is moderate, the organic matter type is good, and the oil generation potential is great. It is determined that the high quality source rocks of the tight oil source rocks in this area are mainly carbonate shale, shaly cloud (ash) rock and clay shale, and felsic shale are the second. The evaluation criteria of type 鈪，
