| 摘 要： | 针对传统的测量抽油井井底压力方法的局限性，在用回声仪测液面折算压力的基础上，考虑了气体在油水中相溶解性和油气水中相容解性和油气水的压缩性，采用与管柱中的流体分布相吻合的n段法计算模式，以及Gilbert相关模型和Podio相关模型，应用微积分方法计算油井的井底压力，实例计算结果表明：该方法计算的抽油井井底压力与压力计实测值误差较小。

| Abstract: | This paper,aiming at limitation of conventional method of measuring the bottom pressure of oil wells and on the basis of converting pressure through testing liquid level by echo sounder ,considered the dissolubility of gas and compressibility of oil and gas and water,adopted n section pattern and Gilbert and Podio correlation models of matching liquid distrbuting phase in pipe lines,and calculated the bottom pressure of oil wells applying the calculus.The results of examples indicated that the error between calculation and measure is minor. |
