游梁式抽油机是我国油田主要应用的采油举升设备,在原油开采中占有重要的地位。但由于其载荷特性不匹配等原因使其工作时存在输出功率波动大、能耗过高、系统效率低下等缺点。本文针对上述缺点,结合永磁传动技术和传感器检测技术,设计了抽油机柔性调速系统,经过现场实践证明,能够有效提高抽油机系统效率,降低了能源损耗。 The beam pumping unit is the main application of oil lifting equipment in China’s oil field, occupying an important position in the exploitation of crude oil. However, due to the mismatch of load characteristics and other reasons, there are some shortcomings such as large output power fluctuation, high energy consumption and low system efficiency. In view of the above shortcomings, combined with permanent magnet drive technology and sensor detection technology, the design of a flexible speed control system of pumping unit, proven on the site, can effectively improve the pumping unit efficiency and reduce energy consumption.
