四川碳酸盐岩裂缝性气藏有单一裂缝系统和多裂缝系统气藏两大类型,就其物性参数搭配和渗流特征来看,两类气藏都应属于裂缝-孔隙型气藏。在开发过程中反映出由于驱动动力不同,开采特征有明显的差异。文中根据四川主要气田的数据初步总结了气驱气藏和弹性水驱气藏的基本特征,并对合理开发这类气藏提出了建议。
The carbonate fractured gas reservoirs in Sichuan Province are composed of two types of single fracture system and multi-fracture system gas reservoirs. In terms of physical property parameters and seepage characteristics, both types of gas reservoirs should belong to fractured-pore gas reservoirs. In the development process reflects the different driving forces, mining characteristics have obvious differences. Based on the data of major gas fields in Sichuan, the basic characteristics of gas-purging gas reservoirs and elastic water-purging gas reservoirs are summarized, and suggestions for the rational development of such gas reservoirs are proposed.
