摘要
本文根据低压抽油井的特点，运用抽油井井筒中的物质平衡和油并流入动态规律，建立了计算抽油井间歇抽油时间和停泵时间的数学模型。在井简条件和抽吸参数已知的情况下，通过数学模型的求解，可以计算油井的最佳抽油时间和最佳停泵时间。同时，该方法也可以用于优选抽吸参数和泵挂深度。该方法的应用可为低压抽油井的生产管理提供科学的依据。
According to the characteristics of low pressure oil wells, using the law of material balance in wellbore and the regular pattern of inflow performance relationship, this paper hasdeveloped the mathematical models for calculating the pumping time and pausing time of intermittent rod pumping wells. With wellbore diameter and pumping parameters given,through the solution of the mathematical models, we can calculate the optimum pumpingtime and pausing time of this kind of wells. At the same time, we can use the models to select the optimum pumping parameters and the pump setting depth.This method provides sci entific bases for the management of low pressure rod pumping wells.
