摘要： 水锁效应是低渗透砂岩气藏开发中普遍存在的问题。为提高低渗透砂岩气藏的气体有效渗透率,尝试用醇来减缓低渗透砂岩气藏水锁效应。以室内实验为基础,对醇处理原理进行了探讨,评价并比较了几种醇溶液用于减缓低渗透砂岩气藏水锁效应的应用效果,实验结果显示:醇处理措施可以有效的减缓低渗透砂岩气藏中由水锁效应产生的伤害。
关键词: 低渗透砂岩气藏, 水锁效应, 醇处理, 表面张力
Abstract: Water blockage is a ubiquitous problem during the development of lowpermeability gas reservoirs. In orderto improve the gas effec-tive permeability of low-permeability gas reservoirs, alcohol has beenused in controlling water blockage. Based on the indoor experiments, the mechanism of alcohol treatment has been studied and the application effect of several alcohol solutions has been evaluated and compared. Result shows that damage caused by water blockage in low permeability gas reservoirs can be effectively retarded by the alcohol treatment.
Key words: low permeability gas reservoirs, water blockage, alcohol treatment, surface tension
