盐岩储气库温度-渗流-应力-损伤耦合模型研究
Study of THM-damage coupling model of gas storage in salt rock with interlayer
摘要
Abstract
Because of the properties of salt rock and particularity of the geographical location of gas storage, there are few studies of the THM coupling model for gas storage in salt rock. Based on the work of THM coupling model of J. Noorishad and C. F. Tsang who is in charge of DECOVALEX in U.S., the mathematic THM-damage coupling model is derived under geostress, injection and production gas pressure and temperature, according to our experimental data of salt rock and our study of gas seepage regulation of gas storage in salt rock with interlayer. In this model, thermal injury effect of salt rock and the Klinkenberg effect of gas seepage are considered. The effect of gas flow along the interlayer surface on the seepage regulation is also considered. Based on it and according to the construction of Jintan gas storage, numerical technology is adopted to get the gas seepage, temperature and stress distribution regulation considering the coupling and uncoupling THM effect, in the process of injection and production. From the detailed comparative analysis, it is concluded that the coupling effect is very significant for gas storage in salt rock with interlayer. This study provides an ideal and premise for the safety and practicably analysis of gas storage in salt rock. This study has an important theoretical and practical meanings.关键词
