高温高盐低渗透油藏调剖技术研究及应用

Research and application of profile control technology for low permeability reservoirs with high temperature and high salt

  • 摘要: 针对江汉油区潜43地层渗透率低、温度高、矿化度高、裂缝较发育的特点,研究了耐温抗盐的体膨型调剖剂JCYJ-1和具有良好注入性能的延缓胶联型调剖剂JCDC-1;同时围绕裂缝发育、注水指进严重的地层特点,研究了复合调剖工艺,解决了裂缝水窜和平面非均质引发的孔隙水窜问题。现场试验见到较好的效果,基本形成了一套适合江汉油区高温高盐低渗透油藏高含水期的调剖稳产技术。

     

    Abstract: Aiming at Qian 43 formation characteristics of Jianghan oil region such as low permeability , high temperature and high salinity , expanded profile control agent JCYJ-1 of heat resistance and salt tolerance and delayed cross linking profile control agent JCDC-1 of good injection performance have been developed. Meanwhile , according to the formation characteristics of fracture development and serious water flood fingering , the composite profile control technology has been studied , which solved the fracture water breakthrough and plane heterogeneity caused by pore water channeling problem.Field test indicates good application results. Therefore , a set of stable profile production technology suitable for low permeability reservoirs with high temperature , high salt and high water cut in Jianghan oil region of have been formed.
