采油井丛式排列为研制新的有杆泵地面设备提供了可能性。其首先涉及到的是耗费材料最大和价格昂贵的抽油机。用一台抽油机带动两台杆式泵的早期试验是钻双筒井,为此开发了调节臂长的双游梁式抽油机,并且有两个侧转驴头,但结构复杂,钢材用量大,并受井距限制。对丛式井而言,国外 Pores clustered provide the possibility to develop new rod pump ground equipment. The first thing it involves is pumping the largest and most expensive pumping unit. An early test of driving two rod pumps with a pumping unit was to drill a dual-well shaft. For this purpose, a dual-beam pumping unit with a long adjusting arm was developed and two side-by-side donkey heads were used. However, the structure is complex and the steel Large amount of use, and limited by the well spacing. For cluster wells, abroad
