摘要
提出了提高油田采收率分两步走的战略：第一步，根据目前油田开发状况和达到的科学技术水平，提高水驱采收率；第二步，采用新的提高采收率方法，进一步提高油田最终采收率。分析了水驱油田的含水上升规律；研究了水驱油田剩余油的分布状况；指出了水驱油田的潜力。最后评述了各种提高水驱采收率的有效方法及其发展方向。
A two-step strategy to enhance ultimate recovery from oilfields is set forth:the first step is to enhance water drive recovery efficiency on the basis of present oilfield development status and by making use of up-to-date science and technology,the second step is to adopt new technologies for enhancing oil recovery efficiency in order to further improve the ultimate recovery from oilfields.The regularities of water cut growth in water-drive oilfields are analyzed,and their residual oil distribution status is studied.The potentiality of water drive oilfields is pointed out.Finally discussed and commented are various effective approaches to enhance water drive recovery efficiency and their developing trend.
