苏里格气田盒8段致密砂岩气储层滑溜水压裂渗吸实验研究

Experimental Study on Sliding Water Seepage and Leakage of Tight Sandstone Gas Reservoir in Section 8 of Sulige Gas Field

以鄂尔多斯盆地苏里格气田盒8段致密砂岩气藏储层为研究对象,对其天然岩心进行了室内自发渗吸模拟实验,具体选择采用质量法和体积法,分析研究了影响致密砂岩储层自吸的因素。实验表明,渗透率、温度因素对致密砂岩岩心渗吸采收率的影响较大,且都为积极影响。

This article takes the tight sandstone gas reservoirs in the He 8 member of the Sulige gas field in the Ordos Basin as the research object, and performs an indoor spontaneous infiltration simulation experiment on its natural core. The mass method and volume method are specifically used to analyze and study the effect of compact Factors of sandstone reservoir self-absorption. The experimental results show that the permeability and temperature factors have a greater impact on the seepage and recovery of tight sandstone cores, and they are all positive effects.
