抽油机井集流式持水率仪取值讨论

抽油田井集流式持水率仪其测试数值测试数据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，提出了改进测井工艺并井曲线面积平均高度取值。

On Value Determination of Packer Wa ter Holdup Meter for Pumping Well

Values from packer water holdup meter for pumping well change with cycles or strokes of oil pumps. Determining the values with curve-averaging-method is not accurate because the values change seriously with different cycles. Particularly for high-water-cut zones, there is considerable error in computing annulus packer production profile. On the basis of the differences of oil/water phases within differect time in puming well and the characteristic of packer logging, several types of curves obtained from water holdup meter are discussed herein. A logging improving technology is put forward, that is ,the values are determined from curve area averaging height.
