套压修正声速提高动液面解释精度研究

本文提出一种用套压修正声速提高动液面解释精度的新方法,此方法严格地以动液面的定义为基础,综合考虑了反映动液面的各个要素,能够真实地反映动液面的真实状况,现场试验证明新方法完全克服了目前采用油管接箍法所存在的一系列问题。

Research on Casing Pressure Amendment of Sounding Wave Velocity to Improve the Interpretation Accuracy of Producing Fluid Level(PFL)

A new method is presented using casing pressure amendment of sounding wave velocity to improve the interpretation accuracy of producing fluid level （PFL） in the paper. The proposed method strictly adoptes the definition of the producing fluid level （PFL） and thought over synthetically each factor that can reflect the property of PFL. The new method could reflect the true status of producing fluid level （PFL）. The field experimental results show that the new method overcomes a series of measures for the problems in oil--pipe connecting.
