东方1-1气田14井区储层孔隙结构特征研究

本文通过铸体薄片、扫描电镜、常规压汞及恒速压汞等实验分析手段,对东方1-1气田14井区储层孔隙结构特征进行研究。结果表明：研究区砂岩类型以岩屑石英砂岩为主,部分为石英砂岩,结构成熟度较高。研究区储层孔隙类型多样,结构相对复杂,根据常规压汞资料可将储层分为三类。孔隙结构是影响储层物性的主要因素,也是影响开发效果的重要因素。

Pore structure research of Dong fang gas field reservoir in well 14

By using casting slice, scanning electron microscopy, the technology of routine pressure and constant velocity Hg injection analysis ways, the paper have a study on pore structure of Dong fang gas field reservoir in well 14. The results show that the reservoir sandstones are mainly the debris- quartz rich sandstone type, part in quartz sandstone, with a middle- high maturity. The reservoir pore various in types and with a complicate structure, it can be divided in three by the constant mercy penetration data. The pore structure is the main factor impacting on reservoir physical property and exploitation effect.
