中文摘要：

塔里木盆地寒武一下奥陶统广泛发育深层碳酸盐岩，白云岩储层中的溶孔、裂缝和溶洞极为发育，是最具储集潜力的缝洞型储层，其发育与否对油气储集有重要影响．为深入研究深层白云岩储层发育条件，利用钻井岩心、沉积相、地球化学等资料，从白云岩岩石学特征和储集空间类型出发，从原始沉积相带、白云石化类型、白云石化程度、构造裂缝发育及深埋岩溶作用几方面，分析了影响白云岩储层质量的主要因素．通过综合分析研究，认为塔里木盆地深层白云岩具有形成优质储层的条件．

英文摘要：

Deep carbonate rocks in Tarim basin are in wide range. It is the most potential reservoir especially in the dolomization area which developed dissolved pore, fractures and dissolved cavern. The dolomite reservoir is very important to the oil and gas accumulation. For researching the developing conditions of deep dolomite, According to the drilling core, sedimentary facies and geochemistry, Starting from the basic of dolostone lithology and space types of reservoir, the paper analyses the main factors of Original sendimentary facies, the types and degrees of dolomization,tectonic fractures and carst process of deep carbonate rocks,Through the analysis and research,deep dolomite reservoir in Tarim basin has the conditions to form high quality reservoir.
