摘要
The west Sulige gas field is located in the He8 and Shanl formations of the Upper Paleosoic Permian, in which low-resistivity gas zone is in coexistence with high-resistivity gas zone. This paper presents the result of analyzing the geneses and characters of low-resistivity gas zone. It is confirmed that main causes resulting in low-resistivity gas zone are clay mineral distribution, the mud filtrate invasion and high immobile water saturation which is the main reason that causes lowresistivity gas zone, and high water salinity is the cause of lowresistivity gas zone as well.
