雷三段碳酸盐岩是川西北中三选统雷口坡组的重要产层,在中坝地区表现为高产孔隙性储集层,并在较大范围内具有相当稳定性,其储集性能可与川南嘉一段负鲕灰岩相媲美。川西北雷三段储集层的主要岩石类型为:藻砂屑白云岩、藻凝块白云岩、藻团块白云岩及砂屑白云岩。形成于潮间及潮下极浅水环境。川西北雷三段常见的孔隙类型有:粒间孔隙、生物体腔孔隙、晶间孔隙、鸟眼孔隙及次
The third member of Leicheng carbonate rock is an important production layer of the Leikoupo Formation of the third election in the northwest of Sichuan Province, which is characterized by high productive porosity reservoirs in the Zhongba area and relatively stable in a large area. Its reservoir Performance and South Sichuan section of a negative oolitic limestone comparable. The main types of rocks in the reservoir of Leicang section of northwestern Sichuan are algal sand dolomite, algae clinker dolomite, algal boulder dolomite and sand litter dolomite. Formed in the intertidal and tidal shallow water environment. The common types of pores in Lei 3 section of northwest Sichuan are: intergranular pores, living body pores, intergranular pores, bird’s eye pores and times
