摘　　要：随着开发时间的延长,水驱油田原主力生产层大部分高能强淹,目前一般采取封堵、调剖细分开采等措施挖潜治理。结合现场实践,从井筒内再次成藏角度提出了“接近零流量法”挖潜强淹层剩余油的一种开采方法,其主要目的是对因特高含水已经或将要废弃的井层采取间歇生产或尽可能降低产液量方法继续动用。现场实施表明,这种方法可以有效挖潜强淹层内的剩余油,是对水驱油田后期开发和挖潜方式的丰富与完善,值得推广应用。As reservoirs enter the high water-cut stage of development, the most primary formations have been badly flooded. At present, the usual measures are shutoffing, profile control, tertiary recovery etc. Basing on the spot practice and the reservoir engineering theory, we take a kind of production method ' approaching zero flux' which is mainly used in the high water- cut oil well or the layer. The field application was very successful. It is a new kind of production way and can increase the production of remaining oil efficiently.
