摘　　要：王培烈·抽油井集流式流量计误差分析·测井技术,1993;17(2):148～153针对集流式涡轮流量计在部分井测试产量偏低,分析了存在的主要问题。讨论了停抽对产量测试造成的误差及停抽后重新稳定所需抽油的时间;指出了“停抽法”取值,集流仪器的压力降落及集流器封隔程度对流量测试均会造成较大的误差,并提出了测试注意要点。Wang peilie.Error Analysis of Packer Flowmeter for Pump Well.WLT,1993;17(2):148～153 Production recorded with packer spinner flowmeter tends to be lower than the true production in some wells.Causes of this problem are analysed in this paper.Error of the flow measurement caused by a stop of pumping and the time needed for stabilization of the flow after the stop of pumping are discussed.It is pointed out that such factors as parameter selection in“stop pumping method”,pressure drop of the packer devices and to what extent the packer may pack off wiLl influence the accuracy of the flow measurement.And con- siderations during testing are also presented.
