气井不关井压力恢复测试技术的应用

Application of Non Shut-in Pressure Build-up Test Technique in Gas Well

改变一次气井产气量(由大变小)可连续测试不关井压力恢复变化。通过现场15井次测试和试井分析表明,气井不关井压力恢复测试技术可以取得与关井压力恢复等效的测试结果,能缩短测试时间、减少产气量损失、提高生产时率,为气田生产提供决策资料。

By changing the gas production rate once time (from big production rate to little), measurement is made on build-up pressure changes continuously. Analyses of detection and well testing to 15 wells indicate that by using the technique the result being equivalent with shut-in pressure is obtained,testing time is short,loss of gas producing potential is reduced and production efficiency is raised. All of that provides strategic data for production of gas oilfield.
