摘　　要：高油气比油井由于泡沫段的影响,使得录取的资料数据误差大而不能准确地计算出油井的真实液面,为此对井中油套环空流体流动状态进行分析,并提出了理论计算泡沫液面的计算公式,即去掉拟泡沫段的拟真液面,使动液面资料真实、可靠,为油井采取措施提供可靠依据。Fluctuation of the producing fluid level is strong for the influence of foam segment in well.So that admission information can not express the liqiud level of pumping well correctly.The flow State of liquid in the tubing-casing annular space was analyzed.The article proposed the theoretical calculation formula of the foam surface.In another words,the pseudo foam segment is taken off,so we can get the correct and reliable liquid level data,which provides dependable information for the measures of pumping well.
