欢26块为辽河油田水驱油藏代表,历经三十多年注水开发,目前整体水淹严重,水驱动用储量严重不均。按目前方式开发,已无有效措施,急需转换开发方式。通过开展深部调驱可行性研究,认为该块适合深部调驱,通过开展先导试验,取得了较好的开发效果,为同类油藏开发提供了借鉴。 Huanghua 26 is a representative of the waterflooding reservoir in Liaohe Oilfield. After more than 30 years of waterflood development, the overall flooding is serious with serious water-driven reserves. According to the current way of development, no effective measures, the urgent need to change the development mode. Through the feasibility study of deep flooding and flooding control, it is considered that the block is suitable for deep flood control and flooding. Through the pilot test, good development results have been obtained, which provides a reference for the development of similar reservoirs.
