本文从车排子地区探井实际资料出发,结合地震资料以及古生物分析资料,对车排子地区地层的横向展布特征进行了研究,基本明确了该区地层的纵横向发育特征;主要目的层新近系沙湾组可以划分为三个砂组;排2井区和排6井区新近系沙湾组为两套完全不同的沉积类型;地层总的变化趋势是由东南向西北减薄;最后对新近系沙湾组的沉积相类型进行了探讨。
Based on the actual data of exploratory wells in Chepaizi area, combining with the seismic data and palaeontological analysis data, this paper studies the stratigraphic horizontal spreading characteristics in Chepaizi area, and basically clarifies the vertical and horizontal developmental characteristics of stratigraphy in this area. The Shawan Formation can be divided into three sand groups; the Paleogene Shawan Formation in Pai-2 well and Pai-6 well are two completely different sedimentary types; the general trend of the strata decreases from southeast to northwest; finally, Sedimentary facies types of the Neogene Shawan Formation are discussed.
