钻井泵功率及功率利用率分析

Analysis of the Power and the Power Using Ratio of the Drill Pump

根据实测结果，分析了钻１口井过程中带泵的电机功率变化规律，和钻１根单根过程中带泵的电机功率变化规律；提出了钻井泵实际功率利用率的计算方法，并具体地对钻１口井过程中的功率利用率进行了计算；分析了３ＮＢ－１３００型钻井泵功率利用率低的原因。

Abstract The changing regulatity of the power which is consumed by the motor of driving a drill pump in the process of drilling a well isaralysized, and the changing regulatity of the power consumed by the motor in drilling a stardpipe. A method of calculating the power using ratis of the drill pump is presenlded, and the practical power using ratio in drilling a well is calculated. The causes are analysized why the power using ratio of the motel 3NB 1300 drillpumps is low, and the measures are put forward which are used to improve the power using ratio.
