摘要: 采油二厂稠油油藏具有“两超五高”的特点,开采难度大,电潜泵作为稠油油藏主要机械举升方式,保证其工况正常是重中之重的工作。电流是反映电泵工况的重要参数,电流的波动直观地反映出油井的生产、电泵的工作状况。根据电泵井电流波动的特点进行分析,提出改善措施,并提出一些新的方法,为后期电泵的稳定生产提供依据。Abstract: Heavy oil reservoirs in No. 2 Oil Production Plant are featured by "super depth, super thickness, high density, high viscosity, high asphaltene-containing colloid, high hydrogen sulfide content, and high salinity", which makes production difficult. Pump is the main machine for lifting, so it is very important to guarantee its normal working conditions. Current is an important parameter reflecting pump conditions, and its fluctuation reflects oil production and pump condition intuitively. This paper analyzed pump current fluctuation characteristics and proposed some countermeasures, which provided a basis for the stable production of pump in the future.
