深井抽油泵的排量系数是深井泵抽油的重要技术经济指标之一。如果排量系数过低,那么,为了获得希望的产量,就必须采用较大的抽油参数,这样就会消耗更多的能量,也有可能增加地面设备的参数等级,从而最终导致抽油成本的增加。因此,对于排量系数较低的抽油井,应当采取相应的措施,提高排量系数。但是影响排量系数的因素十分复杂,有些因素可以进行定量分析,有些因素则很难或根本无法进行定量分析。华东石油学院万邦烈同志在综合分析国外资料的基础上,提出了深井抽油泵排量系数的 The displacement coefficient of deep well pump is one of the important technical and economic indicators for deep well pump. If the displacement coefficient is too low then larger pumping parameters will have to be used in order to obtain the desired output, which will consume more energy and may increase the parameter level of the surface equipment, eventually leading to pumping costs increase. Therefore, for pumping wells with lower displacement coefficient, corresponding measures should be taken to increase the discharge coefficient. However, the factors that affect the discharge coefficient are very complicated. Some factors can be quantitatively analyzed, while others are difficult or impossible to quantify. East China Petroleum Institute Comrade Wanbang Lie on the basis of a comprehensive analysis of foreign information, put forward the deep well pump displacement coefficient
