摘要
地层压力的降低使油井脱气现象非常严重,很多油井从油水两相流发展到油水气三相流。为解决三相流测量问题,适应喇嘛甸油田流饱压差绝对值大于7 MPa产出井测试要求,采用溢气型集流器测井能有效降低气相对产出井测试结果的影响。
The formation pressure decreasing would cause severe degasification resulted in the original oil-water two-phase flow change to oilair-water three- phase flow in oil wells. Using the overflow type gas collector can effectively reduce the influence of gas phase in the production wells,which can solve the problem of measuring 3- phase flow and meet the production demand of the wells in the Lamadian oil field requiring the absolute value of the flow saturation pressure difference to be higher than 7 MPa.
