鉴于目前有些以电机驱动的钻机,仪表化程度尚低,单凭经验掌握钻进情况,往往难于达到最优参数钻进,如果接一个线电流表,在一定程度上可以反映钻进和提升的功率消耗,是有利于改进钻进作业的.现将我公司几年来利用电流表掌握钻井阻力变化的实践情况简介于后,供同志们参考.一、借电流表的指示估计电动机功率马达的线电流值,可以间接地反映钻孔内各种功率或升降功率的变化.功率变化和 In view of some current motor-driven rigs, instrumentation is still low, based on experience to master the drilling situation is often difficult to achieve the optimal parameters of drilling, if you take a line ammeter, to some extent, can reflect the drilling and upgrading of power Consumption, is conducive to improving drilling operations now my company over the past few years using ammeter to grasp the drilling resistance changes in the practice of briefing for the comrades for reference. First, by the ammeter instructions to estimate the motor power motor line current value, Can indirectly reflect the drilling of a variety of power or lift power changes. Power changes and
