中原油田地质条件复杂,开发难度大。由于断块小,井网控制程度低,部分油井受注水影响小或受不到影响,靠天然能量开采。一部分低渗透油井,在低生产压差下难以启动。而边缘井则完全靠弹性开采。近年来,为了挖掘低渗透、低产量、低液面井的生产潜力,中原油田大力发展小泵深抽提液技术,目前已成为油田的主要增产措施之一。小泵深抽工艺技术就是通过加深泵挂,增大泵的沉没压力,放大生产压差,从而保证“三低井”的正常生产,并力求启动新层,增加可采储量。中原油田这些年来,不断应用和发展小泵深抽工艺和配套技术,取得了明显的增产效果。但随着泵挂深度的 Zhongyuan oilfield complex geological conditions, the development of difficult. Due to the small fault block and the low degree of well control, some oil wells are affected by water injection little or not affected by natural energy exploitation. Some low-permeability wells are difficult to start at low production pressure. The edge of the well is entirely elastic recovery. In recent years, in order to tap the production potential of low-permeability, low-output and low-level wells, Zhongyuan Oilfield has made great efforts to develop the technology of deep extraction of small pumps and has become one of the major stimulation measures in oilfields. Small pump deep pumping technology is through deepening pump hanging, increasing the pump submergence pressure, enlarge production pressure, so as to ensure “three low wells ” normal production, and strive to start a new layer to increase recoverable reserves. In the past few years, Zhongyuan Oilfield has made continuous efforts in application and development of deep-pumped pump technology and supporting technologies and has achieved remarkable yield-increasing effect. But with the depth of the pump hang
