大庆油田进入特高含水期后,为了更大程度的提高水驱采收率,开展了两个“二三结合”矿场试验,取得了较好的开发效果,并针对不同类型区块形成特色的配套工艺技术。本文在深入分析“二三结合”试验区效果的基础上,系统总结“二三结合”挖潜技术的方法、形成的支撑技术及推广应用前景,为这项技术的全面推广提供了依据。
After entering the period of extra-high water cut, Daqing Oilfield carried out two “two-three combined” field tests in order to improve the waterflood recovery rate to a greater extent and achieved good development results. According to different types of blocks Formation of the characteristics of supporting technology. Based on the in-depth analysis of the effect of the experimental area of “Combination of two or three ”, this article systematically summarizes the methods of “tapping the potential of the two or three combinations”, the supporting technology and the prospect of its popularization and application, which provides the comprehensive promotion of this technology in accordance with.
