摘要
为了探索四川盆地高温高压气藏储层孔隙度和渗透率的应力敏感特性,选取GM地区震旦系灯四气藏岩心进行储层应力敏感性实验,分析高温高压条件下有效覆压与孔隙度、渗透率的变化关系。实验结果表明,GM地区震旦系灯四气藏储层渗透率应力敏感中等或中等偏弱,孔隙度应力敏感相对较弱。
In order to explore the stress sensitivity of permeability and porosity of high temperature and high pressure gas reservoir in the Sichuan basin,the relationship between the effective overburden of reservoirs and the permeability and porosity with high temperature and high pressure is investigated,based on stress sensitivity experiments of core for Sinian Dengying-4 gas reservoir in GM area. The experimental results show that the stress sensitivity of permeability is medium or medium weak,and sensitivity of porosity is weak in Sinian Dengying-4 gas reservoir in GM area.
