摘要
对高含水中后期提高油田采收率技术研究是油藏后期开发工作中的一项重要内容。针对马厂油田进入高含水开发后期阶段 ,层间动用状况差异大 ;剩余油分布规律复杂 ;井况恶化较严重等诸多矛盾 ,介绍了油田在高含水、高采出开发期为了减缓产量递减、改善油田开发效果、提高水驱采收率应用的主导技术 ,进一步总结了油田开发取得的显著效果 。
Technical research to improve oil recovery rate of reservoir becomes an important content of later reservoir development work while reservoir development gets to high water cut middle and later stage. The paper shows the leading technologies to reduce the degression of the oil output, to improve the development effect of the reservoir, to improve oil water-drive recovery rate when the reservoir development gets to high water cut middle and later stage, aiming at the contradiction of the big difference of output degree between layers, the complexity of the distributing rules of the residual oil and the problem of increasingly worsening well situation that appears while the reservoir development reach high cut water middle and later stage. Also the paper summarizes the remarkable development effect made in the Machang Oilfield development. It provides a good reference for the development of the same or similar reservoir.
