水平注水井电磁流量计注入剖面测井技术试验研究

Experimental Study on Injection Profile Logging Technology of Electromagnetic Flowmeter in Horizontal Injection Well

水平井注水井注入剖面测井需要解决两方面问题,一方面是水平管流的流量测量问题,另一方面是水平段仪器输送问题。为此,采用电磁流量计进行流量测量,利用Sondex公司的牵引器输送测井仪器。实验表明,利用电磁流量计测量水流量结果不受井眼角度影响,电磁流量计可以用于水平井注水井流量测量。现场试验成功录取到水平井注水井注入剖面测井资料。采用牵引器输送电磁流量计可以解决水平井笼统注水井注入剖面测井问题。

Two problems need to be solved in injection profile logging of horizontal wells. On one hand,it is the problem of flow measurement in horizontal pipe flow. On the other hand,it s the instrument conveying in horizontal section. Therefore,the electromagnetic flowmeter was used for flow measurement. The tractor of Sondex Company was used to transport the instrument. Experiments showed that the results of measuring water flow by electromagnetic flowmeter were not affected by borehole angle. Electromagnetic flowmeter can be used for flow measurement of horizontal injection wells. The injection profile logging data of horizontal well was successfully recorded. The problem of injection profile logging in general horizontal injection wells can be solved by electromagnetic flowmeter conveyed by tractor.
