超声波流量计在套管井况检测中的应用

Application of the ultrasonic flowmeter for the measurement in case-damaged wells.

利用超声波流量计测试套管内流量的变化,可以迅速准确地找到套管破损处。该方法不受井壁结垢、油污等影响,测试成功率高。文章介绍了存储式和直读式两种超声波流量计的测试方法及其应用。

The ultrasonic flowmeter can detect the casing deformation rapidly by measuring the flowrate variation in the case.It isn′t influenced by the dirty on the borehole wall,and has high successful ratio.The paper introduces the measuing method and the application of the memory ultrasonic flowmeter and the direct-reading ultrasonic flowmete.
