本文总结了塔里木盆地西北缘露头剖面和典型钻井(草1井与托甫2井)剖面柯坪塔格组岩电及生物特征,并在此基础上对中央隆起区32口主要钻井的柯坪塔格组进行连井地层划分对比及地震剖面标定追踪。结合对等T0图分析,探讨了研究区柯坪塔格组三段分布规律。研究表明,柯坪塔格组上段分布最广,除麻扎塔格-塘参1-顺南地区以南没有发育外,其余地区均有发育,地层厚度一般在100—300m不等,在顺托果勒地区及方1井区以北分布厚度最大,超过了300m。柯坪塔格组上段总体分布表现出南薄北厚、东西分布不均的特点。柯坪塔格组中段与柯坪塔格组下段分布局限,仅在和4-顺西1-顺南3-塔中32井以北地区有发育。柯坪塔格组中段厚度一般只有40—60m,柯坪塔格组下段厚度一般为200—300m,两者厚度均表现出南薄北厚的分布特点。
This paper summarizes the rock production and biological characteristics of the Kepingtage Formation in the northwestern margin of the Tarim Basin and the typical drilling (Cao-1 and Tuo- 2) and on this basis, Tagu Formation stratigraphic correlation and seismic profile calibration tracking. Combined with the analysis of the equivalent T0 maps, the distribution of the third section of the Kepingtage Group in the study area was discussed. The study shows that the uppermost part of the Kepingtage Formation is the most widely distributed, with the exception of Mazhatage - Tongshen 1 - southern part of the Shunnan area where there is no development, the remaining areas are developed, the thickness of the strata generally ranging from 100-300m, The thickness of the area to the north of Togle and Fang 1 was the largest, exceeding 300m. The upper distribution of the Upper Kepingtage Formation shows the features of south thin north and uneven thickness distribution. The distribution of the lower part of the Kepingtage Group and the lower part of the Kepingtage Group is only developed in the area north of Well No.3-4- Shunxi 1- Shunan 3- Tower. The middle section of Kepingtage Formation is generally only 40-60m in thickness and the lower section of Kepingtage Formation is generally 200-300m in thickness.
