摘　　要： 苏里格气田S井区单砂体的空间分布复杂,进一步高效开发气藏难度较大。基于S井区的区域地质、沉积相、测井、钻井、岩心资料,以Cross高分辨率层序地层学理论及其技术方法为指导,采用多级旋回层序划分方案,结合测井相分析技术,对苏里格气田S井区下的石盒子组盒8段,进行了高分辨率层序地层学及测井相研究。通过精细划分和对比,共识别出二个长期、四个中期和十一个短期基准面旋回层序,建立了区内高分辨率地层对比格架。上述沉积相划分和小层对比格架的建立,加深了对S井区砂体纵横向展布规律的认识,为合理制订下一步滚动勘探开发方案提供了地质依据。 The further high efficiency exploitation of gas reservoir is very difficulty because of the complexity of the spatial distribution of single sand body in S area,Sulige Gas Field. Based on the regional geology, sedimentary facies, well logging, well drilling and core data in S area, the study of high-resolution sequence stratigraphy and electrofacies in the low Shihezi Formation of HE-8 member in the area was carried out by adopting the scheme of multistage sequence cycle division and associates analysis-technique of electrofacies and guided by the theory, technique and method of Cross’s high-resolution sequence stratigraphy. This paper not only recognizes 2 long-term, 4 mid-term and 11 short-term base level cycle sequences after fine classification and correlation but also establishes stratigraphic correlation framework with High-resolution in this area. The division of sedimentary facies and establishment of subsequence correlation frameworks above mentioned enhance the understanding for the discipline of the vertical-horizontal distribution of sand body in S area, which make geological foundations for the planning of reasonable cycling exploitation- development scheme in next step.
