| 摘 要： | 简述了８０年代以来国外（主要是前苏联和瑞典）开发的钢带式超长冲程抽油装置用抽油机的结构、类型和特性参数。钢带式超长冲程抽油装置的主要特点是：抽油泵的柱塞冲程很长，从４０ｍ到１５５ｍ；用长钢带代替抽油杆柱作为抽油泵柱塞的传动构件；可用自身的抽油机进行换泵等日常修井工作，停产时间大大减少。钢带式超长冲程抽油装置具有向深井、超深井抽油方向进一步发展的潜力。

| Abstract: | The structures,types and characte.istic parameters of the pumping unit for steel-belt-type ultra-long stroke pumping system are briefly described.The main features of the ultra-long stroke pumping system include:the stroke of the subsurface pump plunger being very long(from 40m to 1500m);using long steel belt instead of sucker rod string as the transmission part of the pump plunger;the pumping unit itself being capable of changing subsurface pump within short outage.The steel-belt-type ultra-long stroke pumping system possesses potentialities for using on deep wells and ultra-deep wells. |
