地面油管漏失定量测试方法探讨

The Quantitative Testing Method of Tubing Lackage in Land Surface

目的：对油管漏失进行定量测试的方法确定具体漏失位置。方法：运用双频道回声探仪探测动液面的原理和工作方法，根据油管漏失形成的死油环在测试曲线上出现特殊波位置判断油管漏失位置。结果：经过70多井次的现场试验，该方法具有较高的准确性和可靠性。结论：利用特殊波可以有效监测油管漏失，并具有推广使用价值。

This paper disscusses the detection principle and method of the producing fluid level using the dual-frequency sonic fluid-level sounder. According to the dead oil ring be reflected in the specific response of tubing lackage testing curve, this method not only can obtain the deepth of producing fluid level,but also can judge the lackage position of downhole tubing. This method is shown have good accuracility and dependability in field testing.
