摘　　要：六盘山盆地发育中生界多套烃源层及下第三系、白垩系、侏罗系三套中新生代碎屑岩储层和一套白垩系碳酸盐岩储层，可形成中新生界下生上储式和白垩系自生自储式等多套良好的生储盖组合，具有良好的勘探前景；盆地沙沟凸起、同心-固原凹陷南部为最有利勘探区，贺家口子-海原凹陷、兴仁堡凹陷、马家庄低凸起为较有利勘探区；沙沟凸起月亮山逆冲推覆构造带、固原凹陷西部单斜带则为盆地中生界最有利勘探区带。There are three sets of source strata in the Mesozoic and four sets of sandstone reservoir(carbonate reservoir) developed in the Mesozoic and Cenozoic strata,therefore maily two corresponding sets of source-reservoir-seal assemblage can be formed;It is pointed out that Shagou heave and the south of Tongxin～Guyuan Depression should be the most favorable area for petroleum exploration,and Yueliangshan thrust-nappe belt in Shagou heave and slope belt in the west of Guyuan Depression should be the most favorable tectonic belt for the Mesozoic petroleum exploration.
