| 摘 要： | 用实验的方法研究了高能气体压裂产生的高温高压气体对地层的酸蚀机理，效果，定性实验表明，酸气与地层碳酸盐成分之间仍然是有水条件下的自发离子反应，高能气体压裂地层条件完全能够提供这样一个环境。定量实验给出了不同酸气强度条件下反应速度，同时获得了反应速度同温度、压力的变化规律。

| Abstract: | This paper studies on the mechanism of acid etching and effect of high temperature and high pressure gas produced by HEGF acting on reservoirs by means of experiment.The qualitative experiment indicates that it is still a spontaneous ionic reaction under water condition between acid gas and the components of carbonatite,this kind of environment can be fully provided by HEGF reservoir.The quantitative experiment provides the reaction velocity under different acid gas intensity,at the same time the changing regularities of the reaction velocity depending on the temperature and pressure are gained. |
