摘　　要：通过岩心观察、铸体薄片以及阴极发光等手段对巴麦地区小海子组的岩石类型及成岩作用做了充分研究。结果表明:小海子组发育的岩石类型中,残余粒屑灰质白云岩和粉晶白云岩的物性较石灰岩要好;成岩作用对储层物性的影响较大,其中建设性的成岩作用有白云石化、溶蚀和破裂作用,破坏性的成岩作用有泥晶化、压实和胶结充填作用,影响不明显的成岩作用有重结晶和压溶作用。此研究对小海子组储层的成岩作用有参考意义,也可为后期勘探提供依据。By means of core observation, casting thin sections and cathodoluminescence, the rock type and diagenesis of Xiaohaizi formation in Bamai region were sufficiently researched. The results shows that the physical properties of residual grain of gray matter dolomite and crystal dolomite are better than those of limestone in Xiaohaizi formation;The influence of diagenesis on reservoir physical property is larger, the constructive diagenesis is dolomitization, dissolution and fracture, the destructive diagenesis is mud crystallization, compaction and cementation filling; recrystallization and pressolution diagenesis have not obvious effect on reservoir physical property. The research has some significances for the reservoir diagenesis of Xiaohaizi formation, also can provide the basis for later exploration.
