摘要
利用INPEFA测井旋回技术,将川西坳陷须家河组五段(须五段)划分为3个四级层序和9个五级层序。利用测井曲线的多元回归方程,定量预测了须五段的总有机碳(TOC)含量。研究表明,在须五段中,TX5-6段优质烃源岩发育最好,其最大累计厚度约为120 m;TX5-5、TX5-7段优质烃源岩的平均厚度为40~50 m,最大累计厚度约为110 m。须五中亚段优质烃源岩的TOC含量为1.8%~4.0%。
With the help of INPEFA logging cycle technology,the 5th member of Xujiahe group can be divided into three four-level layers and nine five-level layers.The multiple regression equation of logging curve parameters is used to quantitatively predict the organic carbon content of the 5th member of Xujiahe group in western Sichuan.The results show that in the 5th member of Xujiahe group in western Sichuan,the high quality hydrocarbon source rock in TX5-6 section has the best development,with the maximum thickness of about 120 m,TX5-5,TX5-7 thickness at 40~50 m respectively.The TOC content of high quality hydrocarbon source rock in Xujiahe Formation is 1.8%to 4.0%.
