高效能极低速控制技术助力油并节能开采
华北油田采油三厂现已进入油田开发后期，低产低效并较多，平均泵效只有12.1%。针对部分低产低效油并供液不足，下泵深，地面设备调参受限的油并，应用高效能极低速控制器，可以实现电机低冲次运转，提高抽油泵的充满系数和油并产量，较好地解决了低产并开采问题。目前，应用的17口油并，平均泵效提升 12.5%，节电量达到20%左右，实现了油并的供排协调、节能开采。为油用单井的节能降耗提供一种新的技术
尝试。
高效能极低速控制技术就是利用棘轮节能效应，将控制装置直接安装在电机的输出轴上，控制器内设柔性机构，可有效控制负载能力，具备瞬间增矩功能，将电机的高速转化为大扭矩低速，负载能力是原电机 2~5倍，可以实现电机0.5次/min的低冲次运转。
