多段塞复合凝胶调驱技术研究与应用

RESEARCH AND APPLICATION OF PROFILE CONTROL AND OIL DISPLACEMENT TECHNOLOGY WITH SECTIONAL COMPOUNDING GEL

    摘要
  • 摘要: 针对大港油田地层中大孔道普遍存在、封堵难度大的情况,进行了水井深部调驱技术的深化研究与应用。在已开发的预交联凝胶颗粒、地下交联凝胶、橡胶颗粒等调驱剂的基础上,研究应用了多段塞复合凝胶调驱体系,提高了对地层中大孔道的封堵强度,取得了较好的治理效果。2001年以来应用以多段塞复合凝胶体系为主体的工艺实施深部调驱193井次,有效率81.3%,累计增油17.53×104t。为注水开发油田的后期挖潜探索了有效途径,具有广阔的应用前景。

     

    Abstract: Research and applications of profile/displacement control technology in deep water wells were developed to solve difficulty of plugging big channels generally exist in reservoirs at Dagang oilfield. Based on the oil displacement profile control agent of developed pre-cross-link gel grains, underground cross-linking gel and elastic grain, developed profile/displacement control system of sectional compounding gel, it enhanced block capacity to big channels in reservoirs, and application in 193 wells since 2001 get 81.3% efficiency, increased crud oil 17.53×104 t. this technology have inaugurated a new approach to tap the latent power of water flooding oilfield and will be gradually popularized and applied.
