针对二连油田水力泵采油方式在油田开发后期出现的诸如因含水上升、细分层系、井数增加造成的动力液处理量增加、系统能力不足、老化油处理困难以及地下油藏动态监测不清等问题，在不考虑水基动力液及闭式系统的情况下，试验研究了老区水力泵井转换采油方式的多种技术工艺措施，最大限度地利用现有的工艺流程，实施抽油机井水力喷射进系统工艺、双管掺水工艺流程、螺杆泵井喷射进系统等技术，逐步克服了以上问题，为油田的高效开发提供了可靠的技术手段。
In view of the increase of hydraulic fluid handling capacity due to the rise of water cut, subdivision and increase of wells in the late stage of oilfield development due to the lack of capacity of the system, the difficulty in handling the aged oil and the dynamic monitoring of the underground reservoir, Qing and other issues, without considering the water-based dynamic fluid and closed-system case, the pilot study of the old district hydraulic pump conversion of oil production methods of a variety of technical measures to maximize the use of existing processes, the implementation of pumping wells Hydraulic injection into the system process, double pipe mixing process, screw pump well injection system and other technologies, and gradually overcome the above problems for the efficient development of the oil field provides a reliable technical means.
