The reason of low system efficiency of the mechanical lifting is: unavailable match between transformer and asynchronous motor with large capacity of equipment and large self-consumption; large average no load less of Y series electrical machinery (31.4% of the total oilfield electrical machinery) with 2.86kw; limited adjustable extent of stroke of the electrical machinery in low-liquid produced wells with minimum value of 4 times per minute for limitation of minimum rotation of the electrical machinery and minimum arc of contact of pulley. Energy consumption will be waste for 1 to 1.5 times per minute is enough.

分析显示，造成抽油机系统效率低的原因主要是：变压器与异步电动机之间匹配方式不合理，设备容量大，自身损耗大；占油田电机总量31.4%的Y系列电机的平均空载损耗大，为2.86kW；低产液井电机的冲次可调范围有限，受电机最低转度和皮带轮最小包角限制，其最小冲次仅可调到4次／min，但1~1.5次／min的冲次即可满足生产需要，造成能耗浪费。
