流压是抽油井监测的重要参数之一．本文提出了流体在井简内的分布模式，介绍了确定混气液密度及井底流压的计算方法──试算法．与其它测试方法相比，该法工艺简单，有一定的准确性．
Flow pressure is one of the important parameters of pumping well monitoring. In this paper, the distribution pattern of fluid in the well is presented. The calculation method of determining the density of the mixed gas and the pressure at the bottom of the well is presented. Compared with other test methods, the method is simple and has certain accuracy.
