抽油机井集流式持水率仪其测试数值随抽油泵冲次周期变化而变化 ,不同周期其数值变化较复杂 ,有时有规律性 ,有时则无 ,采用曲线平均值法取值不准确。特别对高含水地层 ,环空集流法产液剖面计算数值误差较大。根据抽油井管道中油水两相流在不同时间变化型态的差异及集流测井的特性 ,针对持水率录井数值变化经常出现的几种型态加以讨论 ,提出改进测井工艺并用曲线面积平均高度取值。
The test values of the collector water flow meter of the sucker rod wells vary with the period of the sump pump stroke. The numerical changes of the sucker rod wells are complicated, sometimes regular, and sometimes not. The mean value of the curve is not accurate. Especially for high-water-bearing formations, the numerical error of the production profile of the annular current-collecting method is large. According to the variation of oil-water two-phase flow in sucker-rod pipelines at different time and the characteristics of current-collecting logging, several types that often appear in the value change of water-logging are discussed and the improved logging technology is proposed. Area average height value.
