抽油井拟真液面计算及应用

Caculation of Fitting Liquid Level and Its Application to Pumping Wells

抽油井的流压可间接地由动液面折算，但是，由于泡沫段的影响，使得动液面资料误差大而不能准确地计算出抽油井的真实流压值。本文把泵以上混气油柱折算成不含气的纯油柱，即去掉拟泡沫段的拟真液面，使动液面资料真实、可靠，能够较正确地反映抽油井的生产状况和流动压力，为油井采取措施提供可靠依据。该项技术在桥口油田现场应用中已取得较好的效果。

The flowing pressure of pumping well is expressed by producing liquid level. But fluctuation of the producing fluid level is strong for the influence of foam segment in well- So that producing liquid level can not express the flowing pressure of pumping well correctlly. The column of mixing oil with gas is converted into the column of net oil in this paper. In another words, the pseudo true liquid level of pseudo foam segment is taken off,so we can get the correct,ture, stable, dependable, available and comparative information of liquid level, and the production status and flowing pressure of pumping well can be show correctly, and it provides dependable information for the meassures of pumping well. The better effect has been obtalned in Qiaokou Oilfield by using this technology.
