摘要： 油井的井底流压是影响油田的生产能力和油田调整方案的重要参数之一,也是进行油气井动态分析的基础,直接控制井的生产能力。但实际应用中由于地层条件的复杂性,现在并没有一个系统的方法能十分准确的计算出井底流压。在液面折算法计算井底流压的基础上,将油套环形空间中流体分为气柱段、油气段、油气水段三种不同流动形态,研究不同流动形态下混合液密度与压降梯度的关系,采用分段计算模式,应用微积分方法计算油井的井底压力。现场试验结果表明,该方法计算的抽油井井底压力与压力计实测压力值平均相对误差为8.54%,可以满足现场实际需求。

Abstract: Bottomhole pressure is one of the important parameters that affect oil production capacity and the adjustment scheme of oil field. It is also the basis of dynamic analysis of oil and gas wells, and the production capacity of the well is controlled directly. However, due to the complexity of the formation conditions, there is not a systematic method to calculate the bottom hole flow pressure. Based on level conversion method, the fluid in the annular space of an oil sleeve is divided into three different flow patterns of gas column, oil and gas and oil gas water. The field test results show that the average relative error between the measured pressure value and the measured pressure value of the pumping well bottom hole pressure of the pressure gauge is 8.54%, which can meet the actual needs of the field.
