摘要

为了降低低产井开发成本,延长检泵周期,在某低产区块进行电动潜油柱塞泵及其配套技术现场试验。根据该区块特点,设计试验方案,将机械开采方式由抽油机改造为电动潜油柱塞泵,并配套闭环控制技术、远程控制技术和新型工具,通过对比改造前后的生产参数,评价电动潜油柱塞泵系统的工作性能。由试验数据显示,在日产液量基本不变的情况下,电动潜油柱塞泵比抽油机系统效率提高4.4%,节电率达到30.7%;电动潜油柱塞泵应用闭环控制技术,可以有效降低冲击载荷,使系统运行更加稳定,比常规控制技术节电27.3%;采用远程控制技术可以在线获取生产参数,减少巡井工作量。结果表明,电动潜油柱塞泵对低产区块具有良好的适应性,拥有广泛的推广价值,是油田节能降耗的重要技术支撑。
In order to reduce the development cost of low production wells and prolong the pump inspection period,the field test of the electric submersible plunger pump and its supporting technologies have been carried out in a low production block. The test scheme was designed according to the characteristics of the block, and the artificial lift was changed from the pumping unit to the electric submersible plunger pump. The closed-loop control technology,remote control technology and other new tools were also equipped. By comparing the production parameters before and after reforming, the work performance of electric submersible plunger pump was evaluated. The test data showed that the system efficiency of the electric submersible plunger pump could rise by 4. 4% and electric energy-saving ratio reach 30. 7% compared with the pumping unit system under the basically unchanged daily fluid volume. The application of the closed-loop control technology of electric submersible plunger pump can effectively reduce the impact load which makes the system running more stable, saving electricity of 27. 3% compared with the conventional control technology. Remote control technology can obtain the production parameters online; reduce the workload of patrolling wells. The results showed that electric submersible plunger pump has good adaptability in the low production block, with extensive popularization value. It is an important technical support for energy saving in oilfield.
