Principle and Application of Synchronous Test Technique of Three Parameters for Well Test

试井三参数同步测试工艺是由地面智能计深装置和井下高精度存储式电子压力计共同实现的 ,给出了它们的工作原理。对现场应用效果进行了分析 ,利用该技术可以准确判断气举凡尔工作状况或油管漏失位置 ,为气举井工况分析提供可靠依据 ;利用压力、温度剖面 ,可直观准确地读出探液面深度 ;通过连续监测气举井压力、温度变化 。

A three parameter synchronous test process is implemented by surface intelligent depth meter and a high precision storage electronic pressure meter, for which working principles are given. Field application effect is analyzed, the working status of gas lift valve and tube leaking positions could be accurately judged by using the technique so as to provide basis for analyzing the working conditions of gas lift wells. Pressure and temperature are used for visually and accurately reading out the detected liquid depth. A working system could be determined rationally through continuous detection of pressure and temperature changes in gas lifting.
