摘　　要：本文通过岩心观察、镜下薄片分析和压汞试验等手段,开展了对塔里木盆地巴楚隆起带寒武系白云岩储层特征的研究。研究发现,研究区地层岩性主要为石灰岩和白云岩且白云岩沉积厚度大。按照白云石晶粒的大小,研究区白云岩被划分为三种类型,分别为粉-细晶白云岩、细-中晶白云岩和中-粗晶白云岩。笔者对白云岩储层饱和度、孔隙度和渗透率进行了研究,分析了三种类型白云岩的孔渗关系,探讨了沉积环境、成岩作用和裂缝对白云岩储层的影响。In this paper,the characteristics of the Cambrian dolomite reservoirs in the Bachu uplift belt of the Tarim Basin are studied by means of core observation,microscopic sheet analysis and mercury intrusion test.The study found that the lithology of the study area is mainly limestone and dolomite and the dolomite deposit thickness is large.According to the size of dolomite grains,the dolomites in the study area are divided into three types,namely powder-fine-crystalline dolomite,fine-medium-crystalline dolomite and medium-coarse crystalline dolomite.The author studied the saturation,porosity and permeability of dolomite reservoirs,analyzed the pore-permeability relationship of three types of dolomite,and discussed the effects of sedimentary environment,diagenesis and cracks on dolomite reservoirs.
