摘　　要：根据薄片、岩心、扫描电镜、压汞和物性等资料分析,吐孜气田吉迪克组(N1j)储层岩性主要为褐色泥质粉砂岩、粉砂岩;碎屑成分以岩屑为主,碎屑颗粒以粉砂级为主,分选中-好,成熟度较高;储集空间类型以粒间溶蚀孔为主,裂缝不发育,喉道类型以缩小型和缩颈型喉道为主。综合分析,沉积作用对储层控制作用最强,使得储层发育连续,但不同相带储层发育仍有不同;其次是成岩作用,使储集空间类型多样,孔隙结构复杂。综合考虑储层岩石类型、孔隙结构和物性特征,建立分类评价标准,对区内储层进行评价。The data analysis of core,slice,scanning electron microscope,mercury intrusion and physical property indicated that the main reservoir lithology in N1 j was brown argillaceous siltstone and siltstone,the clastic constituents were mainly debris,its grain was mainly of silt grade,its sorting was mid-good with higher maturity.The reservoir space type was mainly intergranular dissolved pore and fractures were not developed,the pore throat type was narrow and necking one.Comprehensive analysis shows that the sedimentation is the most important parameter to control the reservoir quantity,where the reservoir is continuously developed there are different reservoirs developed in different facies zones.The second important control parameter is diagenesis,there are various of reservoir types with complex pore structures.Based on the study,the evaluation criteria of each type of reservoir are established for evaluating the reservoirs in the area.
