针对海1块长期注水开发,储层非均质进一步加剧,使地层压力场、流线场形成定势,油水井间形成优势水流通道,注入水波及体积难以提高的问题,选择4口注水井,采用有机铬凝胶体系,进行深部调驱试验。结果表明,该项技术解决了注入水沿大孔道无效串流,注水利用率低的问题,达到了降水增油的目的,为辽河油田千万吨稳产做好了技术储备。 In view of the long-term waterflood development of Hai 1, the heterogeneity of reservoir is further aggravated, the formation pressure field and formation of streamline field, the formation of dominant water flow channel between oil and water wells, the infiltration of water and the difficulty of increasing volume are selected. Four injection wells , The use of organic chromium gel system, the depth of the drive test. The results show that the technology solves the problem of invalid flow of injected water along large channels and low water injection efficiency, and achieves the purpose of precipitation and oil increase, thus making a good technical reserve for tens of thousands tons of stable production in Liaohe Oilfield.
