四川盆地西北部中二叠统茅口组储层非均质性较强、控制因素复杂,影响了正确认识储层分布规律.本文利用野外剖面和钻井岩心的宏观与微观特征,结合测井等资料,分析川西北地区茅口组储层特征,探讨其主控因素.茅口组发育中孔、中渗的孔隙型白云岩储层和特低孔的裂缝型灰岩储层.储集层主要分布在茅口组顶部的第三段,受沉积、成岩和构造控制明显.台地边缘商能潍核易形成孔隙型白云岩储层,构造发育区易于裂缝型灰岩储层的形成.台地边缘滩核及裂缝发育区带是川西北地区茅口组勘探的方向.%On the basis of field profiles,drilling cores,microscopic slices and logging data,the reservoir characteristics and its main controlling factors in the Middle Permian Maokou Formation of the northwestern part of the Sichuan Basin are studied in order to solve the problems of reservoir heterogeneity and complicated controlling factors of the Middle Permian Maokou Formation reservoir.It is considered that there are two types of reservoirs in Maokou Formation,one is the pore type dolomite reservoir with medium porosity and permeability,and the other is the fractured limestone reservoir of extremely low porosity.The reservoir is mostly distributed in the Member 3,at the top of the Maokou Formation,which is evidently controlled by deposition,diagenesis and structure.It shows that the pore type dolomite reservoirs are easily formed in the high energy bank at the edge of the platform,while fractured limestone reservoirs are usually developed in the tectonic belt.Therefore,place near the fault zone and the edge of the platform is the favorable directions for the future exploration of the Middle Permian Maokou Formation of northwestern Sichuan.
