摘要
低油价形势下为了进一步降低抽油机井能耗、提高抽油机井系统效率,建立了整合间抽生产与连续生产方式统一的抽油机井节能优化模型。该模型在完成相同产量的前提下,合理组合主要生产参数,从降低生产时间及降低生产单耗2个方面协同降低抽油机井日耗电。在此优化模型的基础上,提出了模型求解的无极间开设计方法,该方法可实现连续生产与不同生产时间的间开生产能耗对比,得出日耗电最低的生产参数组合。现场应用表明,与常规连续优化相比,无极间开优化可以有效降低中、低产抽油机井系统能耗,进一步提高其机采系统效率。该统一模型及其求解方法为确定抽油机井选择连续生产或是间抽生产提供了经济评价依据,尤其对中低产井的节能优化具有指导意义。
At present low oil price, it is necessary to minimize energy consumption of rod-pumped wells and enhance efficiency of rod-pumped well systems. Accordingly, uniformed optimization model with combination of intermittent production and continuous production for energy conservation in rod-pumped well has been constructed. With proper production parameters, the new model can effectively reduce daily power consumption by rod-pumped well jointly through minimization of production and reduction of unit consumption without compromising productivity. Based on the optimization model, design for stepless intermittent operation has been proposedto provide solution to the newly constructed model. By comparing energy consumptions of intermittent production and continuousproduction, combination of optimal production parameters can be identified to minimize daily power consumption. On-site applicationresults show the stepless intermittent operation optimization can further reduce energy consumption of rod-pumped well with mediumor low productivities than the conventional continuous optimization. In this way, the efficiency of production system can be furtherenhanced. The innovative uniformed model and relevant solutions may provide reliable data for economic assessment on continuous or intermittent production in rod-pumped well. Relevant research results may provide necessary guidance for energy conservation and performance optimization in wells with medium or low productivity.
