在注入剖面五参数组合测井中,流量连续测试测试结果与点测结果经常相差较大,本文从相位差法超声波流量计的工作原理及工作环境出发分析了流量连续测量误差产生的主要原因,阐述了同位素测井中流量点测优于连续测试的观点。
In the injection profile five-parameter combination logging, the results of continuous flow test and spot measurement often differ greatly. This paper analyzes the main causes of the continuous flow measurement error from the working principle and working environment of the phase difference ultrasonic flowmeter, The point of view of flow measurement in isotope logging is better than that of continuous measurement.
