通过对大庆油田抽油机井的井口回压、产液量和耗电量的实测,对由井口回压的提高(在设计规范值内)引起的油井产液量和耗电量的变化进行了分析和探讨。一、测试井的选择为使测试结果更具真实性和代表性,测试井的选择应遵循以下几项原则:井口回压便于控制;产液量宜于连续准确计量;油井产液量和含水率有一定的范围;深井泵泵径在矿场上具有普遍性;泵况正常(无撞泵、脱泵、漏失、供液不足等不良工况);油井产液量和动液面
By measuring wellhead back pressure, fluid production and power consumption of Daqing Oilfield pumping wells, the changes of well production and power consumption caused by the increase of well head back pressure (within the design specifications) Analysis and discussion. First, the choice of test wells To make the test results more authentic and representative, the selection of test wells should follow the following principles: Wellhead back pressure is easy to control; liquid volume should be continuous accurate measurement; oil well liquid production and water Rate of a certain range; deep well pump diameter in the mine is universal; normal pump (no collision pump, pump, leakage, inadequate liquid supply and other bad conditions); oil well liquid production and dynamic liquid
