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。
