大庆油田萨北区块已经进入高含水开发阶段,在降本增效的大环境下,处于开发后期的聚驱抽油井合理高效的生产是油田面临的重大挑战之一。而沉没度是抽油机的重要的运行指标和动态参数,是影响杆柱寿命、产液量、机采效率以及能耗的重要因素。本文结合现场实际,分析了沉没度与泵效、生产效率、吨液百米耗电、泵况问题发生率间的关系,得到了适合当前萨北区块聚驱井开发的合理沉没度区间,为该区块沉没度管理调控提供一定的方向。
Daqing Oilfield Sa Bei block has entered the stage of high water cut in the cost reduction and efficiency of the environment, in the late development of the polymer flooding well rational and efficient production is one of the major challenges facing the oil field. The submergence degree is an important operating index and dynamic parameter of the pumping unit. It is an important factor that affects the life of the column, the volume of liquid produced, the efficiency of the machine and the energy consumption. In this paper, the relationship between submergence and pump efficiency, production efficiency, electricity consumption per 100 meters and the incidence of pumping problems are analyzed based on the actual situation in the field. The reasonable submergence interval suitable for the current development of poly-flooding wells in northern Saab district is obtained as The subsidence management of the block provides a certain direction.
