| 摘 要： | 为预测塔里木盆地阿克库勒地区白垩系油气勘探的有利区带，运用层序地层学理论，根据岩心、测井和地震资料，建立了该区白垩系层序地层格架，并探讨了其与沉积、构造演化的对应关系。结果表明：阿克库勒地区白垩系包括2个二级层序，分别相当于巴什基奇克组和卡普沙良群，其中卡普沙良群又细分为3个三级层序。研究区发育辫状河三角洲、曲流河三角洲、湖泊等沉积相类型。油气勘探应主要寻找阿克库勒地区卡普沙良群底部Sq1的低位及高位体系域的储集砂体，平面上以研究区中南部的三角洲前缘相带储层为最优。

| Abstract: | In order to forecast the favorable zones of the Cretaceous in Akekule area in Tarim basin, based on sequence stratigraphy theory and analysis of cores, logging and seismic information, the sequence stratigraphy frame is established, and the relationships between the frame and sediment, and the frame and structural evolution are analyzed. The results show that there are two second-order sequences, which correspond to Bashenjiqike Group and Kapushaliang Group. The Kapushaliang Group is divided into three third-order sequences. The types of sedimentary facies are braided delta, meandering delta, and lacustrine facies. The sand bodies of lowstand system tract and highstand system tract of Sq1 are favorable explore targets in the south part of Akekule area. |
