地热井采灌失衡的解决途径及工程应用

Solution to Imbalance between Exploitation and Recharge of Geothermal Wells and Its Engineering Application

针对天津地区地热井存在的采灌失衡问题,提出3种解决方法(酸洗压裂回灌井、补建回灌井、两眼开采井整合为采灌对井),对3种解决方法在工程中的应用进行了探讨。

To solve the problem of imbalance between exploitation and recharge of geothermal wells in Tianjin region, three kinds of solutions including acid fracturing recharge well, digging recharge wells and integration of two exploitation wells into exploita- tion and recharge wells are put forward. The applications of the three solutions to the engineering are discussed.
