铝合金抽油杆柱深抽的初步研究

机抽井深抽是恢复油井产量行之有效的措施，为解决钢质杆深抽时驴头负荷、曲柄扭矩和杆柱应力过大的问题，我国西部某油田提出了使用铝合金抽油杆的设想。本主根据抽油杆柱设计理论导出了深抽杆柱各级下入深度的公式；对不同工艺参数配合下的计算结果进行了对比分析，对铝合金抽油杆柱用于深抽的可行性进行了初步研究。

Preliminary Research on Aluminum Sucker Rod in Deep Well Pumping

It is an effective way to enhance or recover oil production by increasing the pump setting depth. An assumption is put forward by a western oil field of our country to solve the overload of the horsehead, the over torque of the crank and the over stress of the string by using aluminium sucker rods instead of steel rods in deep well pumping. In this paper, the formula of setting depth of taper rods is derived according to the theory of pumping rod design, and a contrast analysis is made about the calculation result under a series of different technological parameters，Besides the preiiminary study of the feasibility is conducted that aluminium rods are used in deep well pumping.
