Abstract

Abstract: The geological and recovery characteristics of onshore oilfield in China were summarized.The policies of early-stage inter-water-flooding and stepwise enhanced recovery are the major ways for oilfield development in China.With the progression of recovery,the efficiency of enhanced recovery is low,which is disadvantageous for improving technical and economic benefits in the high water-cut stage(over 80%) of oilfield.Aiming at reducing water-cut and enhancing sweep efficiency,a high-efficiency secondary recovery way for the instable water-flooding program was proposed.This way can improve the technical and economic performances.

Key words: oilfield, water-flooding development, continental reservoir, enhanced injection and recovery, enhanced oil recovery, instable water-flooding, second recovery

摘要： 总结了中国陆上油田的地质特点以及由此决定的开采特征.中国油田开发的基本方式和开采方针是早期内部注水、逐步强化开采.随着开采过程的延伸,在油田高含水后期开发(综合含水率大于80%)中采用强化开采方式是低效的,不利于提高油田开采的经济效益和技术效果.提出了以降低含水率和提高注水波及体积为目标,建立以不稳定注水为中心的高效二次采油方式,从而改善了油田开发的技术经济效益.
