致密砂岩气藏有效砂体分布及主控因素--以苏里格气田南区为例
Effective sand body distribution and its main controlling factors in tight sandstone gas reservoirs:A case study of southern Sulige Gas Field
摘要
Abstract
The southern Sulige area is the southward extension of the main part of the Sulige Gas Field, where is far from sediment provenance, buried deep and has a strong diagenesis. Understanding the distribution character⁃istics and main controlling factors of effective sand body is the basis of the efficient development of the edge re⁃gions of the Sulige Gas Field, such as the southern Sulige area. Focusing on the reservoirs of He8 member and Shan1 member, the areas of tectonic, sedimentation, reservoir and diagenesis were studied, and the distribution characteristics and main controlling factors of effective sand body were concluded. The effective sand bodies in the southern Sulige area mainly distribute in point bars and the bottom of distributary channels, and can be verti⁃cally classified into three types:isolated, vertically stacking, and laterally shiplap ones. Horizontally, they locate in the central and eastern sand belts of the study area. During the formation of effective reservoirs, a gentle struc⁃ture background is necessary for the sedimentation and formation of gas reservoirs. The shallow braided⁃river delta plain deposits in the strong hydrodynamic environment determined the distribution pattern of reservoir, whereas the compaction, cementation and dissolution diagenesis before the formation progress of gas reservoirs greatly re⁃formed the reservoirs and controlled the distribution of effective sand body.关键词
