The reservoir lithology is mainly the clastic sandstone, the poroustype of the reservoir is various, the pore and throat is tiny, and the pore configuration is bad.
储层岩性主要为岩屑砂岩，储层孔隙类型多，孔喉细小，孔隙结构差。

We also pointed out that the study area mainly developed fractured and poroustypereservoir, lateral extensibility is small, presenting lenticular and en plaque.
同时指出该区以裂缝-孔洞型储层为主，侧向延伸不远，呈透镜和斑团状分布；

Porous-type sandstone reservoir is shorter and shorter and gas reservoir in tight sand is more and more important.
