摘要
采用气体泄漏测试方法对完井盐穴储气库进行密封性检测,通过向测试管柱和生产套管之间的环空中注入氮气或空气,并使气水界面深度位于生产套管鞋以下的腔体脖颈处。在测试管柱中下入测井仪器,测试气水界面的深度,监测井口压力,流体流量和温度等参数,根据腔体泄漏率随时间的变化趋势和气水界面深度变化值对腔体密封性作出评价。
The gas leakage test method is used to test the tightness of the salt cavern gas reservoir in the completion well.Nitrogen or air is injected into the ring air between the test string and the production sleeve,and the gas-water interface depth is located at the neck of the cavity below the production casing shoe.Logging instruments are used to test the depth of the gas-water interface in the test string,to monitor the wellhead pressure,fluid flow and temperature and other parameters,and to evaluate the sealing performance of the cavity according to the variation trend of cavity leakage rate over time and the variation value of gas-water interface depth.
