HCXJC270-6抽汲式采油绞车的研制

为了解决小区块、油量较小油田的采油问题,设计了HCXJC270-6抽汲式采油绞车。该采油绞车由发动机模块、变频电控模块、电动机模块、机械传动模块以及滚筒与排绳模块组成,它利用发电机产生电能通过变频器的调节实现在操作室内对电动机转速的控制,进而实现对绞车抽采速度的控制。现场试验表明,在井内放出2500m钢绳,逐步加载可顺利提升50kN(等效于5000m钢绳全部放出的设计载荷)重物,拉力计显示63.13kN;加载到70kN(等效于5000m钢绳全部放出的设计极限载荷),仍可顺利提升,排绳机构运行正常。变频控制器响应灵敏,刹车手柄等操作无滞阻。

Development of the HCXJC270-6 swabbing oil production winch

To solve the problem of oil production in small-block and low-yielding oilfields,the HCXJC270-6 swabbing oil production winch was developed. The winch consists of the engine module,the frequency conversion and electric control module,the electric motor module,the mechanical driving module,and the roller and rope-arranging module. It uses the power generated by the generator and regulated by the frequency converter to achieve the control of the rotation speed of the electric motor in the operating room,thus controlling the swabbing speed of the winch. The experiment shows that the release of the 2,500-meter-long wire rope in the well with gradual loading can smoothly lift 50 kN,which is equivalent to the designed load of the full release of the 5,000-meter-long wire rope,and the tensometer indicates it is 63.13 kN. When the load reaches 70 kN which is equivalent to the design limit of the full 5,000-meter-long wire rope release,the lift still continues smoothly and the rope-arranging mechanism runs properly. The response of the variable frequency controller is sensitive and the brake handle is operated smoothly.
