摘　　要：目的探究塔里木盆地下古生界白云岩储层发育条件。方法依据露头、岩心观察、镜下鉴定和地球化学指标进行综合分析。结果有利的原始沉积相带、白云石化作用的程度与类型、深埋岩溶作用、断裂作用及其伴生裂缝是储层发育的关键。结论塔里木盆地下古生界白云岩具备发育成优质储层的条件,存在着巨大的勘探潜力。Aim To research the Lower Palaeozoic dolomite in Tarim Basin. Methods Based on outcrop and core observation, SEM and thin section analysis, geochemical indicators analysis. Results The conclusions are the favorable original facies belt, the degree and types of dolomization, karstification in deep depth, fracturing and its associated fractures are the keys to the development of the reservoir. Conclusion The Lower Palaeozoic dolomite in Tarim Basin meets the conditions for a high quality reservoir which has great potential for the petroleum exploration.
