克拉玛依油田八区八道湾组测井层序地层学研究

Well logging sequence stratigraphy of the Badaowan Formation in the 8th block of the Karamay Oil Field, Xinjiang

摘要: 通过对克拉玛依油田八区下侏罗统八道湾组层序地层学总体特征,特别是测井层序的分析,并与邻区进行对比研究,识别出了3个三级层序界面,将八道湾组划分为2个层序、5个体系域,分别对应5个砂层组;同时简要论述了各体系域的特征,完成了八道湾组的地层层序划分。

Abstract: The Lower Jurassic Badaowan Formation occurs as main oil reservoirs in the Karamay Oil Field, Xinjiang. Three sequence boundaries, two sequences and five systems tracts corresponding to five sand sets are recognized on the basis of the analysis of well logging sequences in the study area. The features of individual systems tracts are generally expounded in this study.
