摘要
为了提高低渗透、低产能油藏的开发水平，保证油井在最佳的状况下生产，通过井筒油、气、水三相流体体积流量计算方法的研究，推导出了抽油井泵的充满系数与泵口压力的关系，进而得到了不同含水率时合理井底流动压力的计算方法。控制油井在合理流动压力下工作，进入泵筒中的气量是有限的，可以保证泵在最佳的工作状况下运行。
In order to improve the development levels of low-permeability and low-productivity oil reservoirs and ensure the optimum operation of the oil wells, through the calculating method researches on the volumetric flow of oil, gas and water, the relationship between the coefficient of fullness and the pump inlet pressure is derived in this paper and furthermore a method for calculating a reasonable BHFP （ bottom hole flowing pressure ） is presented. This method can be used to make oil wells operate under reasonable flowing pressure and control the volume of gas entered into the pump barrel, so and the optimum performance of the pumps can be effectively ensured.
