| 摘 要： | 西安市地热田储层为砂岩孔隙型储层,孔隙度和渗透率都比较低,很容易发生回灌堵塞现象。对西安市同层回灌水和异层回灌水的配伍性进行研究,配伍性实验结果表明:西安市地热尾水回灌到回灌井后主要的结垢类型为CaCO3,结垢量小于100 mg/L,配伍性较好,不会大量结垢而导致地热储层堵塞。

| Abstract: | The type of reservoir is the geothermal reservoir of porous type in Xi’an,the porosity and permeability is low that it is easy to clogging the injection well when starts reinjection.The article proposed to stuy the compatibility of the reinjected water in the same geothermal reservoir and different ones.The experimental results of compatibility show that the main type of scaling is CaSO4 and CaCO3 after each compatible test in the same layer and different ones,and the amount of scaling is less than 100mg/L.Therefore,the result of compatibility experiment is well and it will not form a great quantity of scaling to clogging the geothermal reservoir. |
