摘　　要：玛湖凹陷的玛北斜坡区油气勘探取得了重大突破,而与之相邻的玛西斜坡区勘探效果甚微。为此,根据岩心、薄片、扫描电镜等资料,对玛北与玛西斜坡区百口泉组储集层的岩石学特征、成岩作用对比分析,认为储集层物性特征及其控制因素存在明显差异,压实作用、胶结作用与溶蚀作用是造成储集层物性差异的根本原因。玛西斜坡区含油气远景优于玛北斜坡区,玛西斜坡区深层是有利储集层分布区,扇体两翼和玛中1井区是下一步油气勘探的重点。Major breakthroughs to oil and gas exploration have been made in the northern slope of Mahu sag, but little exploration effect has been obtained in the adjacent western slope. According to the data from cores, thin sections and scanning electron microscope, the petrological characteristics and diagenesis of the Baikouquan reservoirs in the northern and western slopes are compared and analyzed. It is found that the reservoir physical properties and controlling factors are very different, and compaction, cementation and dissolution are fundamental causes for the different reservoir physical properties. The western slope is better than the northern slope in oil and gas resources.Favorable reservoirs are distributed in the deep of the western slope, and future exploration should focus on the two wings of the fan delta and the area around Well Mazhong-1.
