螺杆泵采油技术在低渗透油藏定向井中的应用

针对游梁式抽油机-有杆泵采油方式在低渗透油藏部分区块定向井应用过程中出现的油井免修期短、维护成本高的问题,在6口低渗透油藏定向油井应用了螺杆泵采油工艺,现场运行效果表明,螺杆泵采油工艺可有效的延长油井的检泵周期及提高泵效,为长庆油田低渗透油藏定向井采油提供一种新的举升方式。

Screw pump technology in low permeability reservoirs directional wells

Beam pumping unit - way of rod pump production in low permeability reservoir part of the application process blocks appear in directional wells wells exemption period is short,the problem of high maintenance cost,low-permeability reservoirs in six directional wells application of the screw pump technology,field effect shows that,screw pump technology can effectively check the extension of the well pump cycle and increase pump efficiency,the Changqing oilfield directional wells in low permeability oil reservoir to provide a new way of lifting.
