摘要:
针对注入压力波动大、压力调节弹簧变形、出现大面积腐蚀和恒流水嘴阀芯移动不顺畅的实际问题,通过对压力调节弹簧、恒流阀芯、注水孔道、节流滤网等进行工艺、组成上的改进,有效解决长稳定配水堵塞器的技术瓶颈问题,并在低渗透油田中进行现场生产应用。通过分析地层渗流能力,确定主力吸水层段,依次进行常规测调、利用长稳定配水堵塞器测调,建立两种测调技术的数据分析表,验证长稳定配水堵塞器的应用效果。根据现场应用效果分析表明:长稳定配水堵塞器具有较强的控水能力、较好的稳流效果,可有效延长测调稳定时间,较好地解决注水层间矛盾问题,对测调效率提升有重大意义。长稳定配水堵塞器可实现层段精细注水、长期有效稳流,提升测调工作效率。
Abstract:
For the practical problems of large injection pressure fluctuation,pressure adjustment spring deformation,large area corrosion and unsmooth movement of the constant flownozzle,the process is performed by a pressure regulating spring,a constant flow valve core,a water injection hole,and a throttle filter. The improvement of composition effectively solves the technical bottleneck problem of long stable water distribution plugging device and performs onsite production application in low permeability oilfield.By analyzing the seepage capacity of the formation,the main waterabsorbing layer section is determined,and then the conventional and longstable water distribution plug are used to measure and adjust in turn,and the data analysis tables of the two methods are established to verify the application effect of the longstable water distribution plug.According to the analysis of field application results,the long stable water distribution plug has strong water control capacity and good steady flow effect,which can effectively extend the time of measuring and adjusting stability,and also solve the contradiction between water injection layers,which is of great significance to improve the efficiency of measurement and regulation.Longterm stable water distribution plug can realize fine water injection,longterm effective steady flow,which improve the efficiency of measurement and adjustment,and provide an important basis for the adjustment of oilfield development plan.
