摘要: 随着塔里木等深层油气田的开发,能够满足深井大排量深抽的工艺技术逐渐成为现实需要,考虑到机采井的泵挂深度不断加深,单一的举升方式随着举升高度的增加往往表现出一定的局限性和低效性,因此,针对性地提出有杆泵-地面驱动螺杆泵组合举升工艺,将螺杆泵和有杆泵安装在同一生产管柱上进行“接力”采油。为论证有杆泵-地面驱动螺杆泵组合举升工艺的可行性,在分析有杆泵-地面驱动螺杆泵组合工艺的工作原理、流量匹配及杆柱受力状况的基础上,建立了有杆泵-地面驱动螺杆泵组合举升工艺在油井深抽条件下的悬点载荷计算模型,与单独的有杆泵抽油相比,在保证产量相同的情况下,该组合系统能通过降低抽油机悬点载荷达到增加泵挂深度及排量范围、降低抽油能耗的目的。

Abstract: Along with the development of deep oil and gas fields such as Tarim, satisfying the technology of deep and large pumping in deep well has gradually become a reality. The pump setting depth is deepening, the single way of lifting tend to show some limitations and inefficiency, so we propose a combination of lifting technique of sucker rod pump and ground driving screw pump: the screw pump and plunger pump being installed on the same production string, and the relaying way of extracting oil carried out. In order to demonstrate the feasibility of the lifting technique of rod pump and ground drive screw pump, we analyze the working principle, flow matching and force condition of the rod pump and ground drive screw pump, and establish the suspension load calculation model of the combined lifting process of the rod pump and the ground driving screw pump in the deep pumping conditions of the well. Compared with sucker rod pump, the swabbing parameters in the same production case of combination lifting system of sucker rod pump and ground driving screw pump will increase the depth of pump and the range of displacement, and reduce the energy consumption by reducing the polished rod load of the pumping unit.

Key words: the lifting technique of combination, sucker-rod pump, ground driving screw pump, feasibility analysis, comparative analysis
