垦西油田垦 71断块经过 2 0余年的高速开采 ,已进入特高含水开发期 ,油层水淹严重 ,剩余潜力小。本文主要通过对油藏开发后期高含水油藏的油层水淹情况及剩余油分布规律进行了研究 ,为今后该类油藏的挖潜提供借鉴。
After 21 years of high-speed mining, the Ken 71 block of Kenxi Oilfield has entered the period of ultra-high water-cut development with serious flooding and low residual potential. This paper mainly studies on the flooding condition of oil reservoir and the distribution of remaining oil in the later stage of reservoir development, and provides references for the potential tapping of such reservoirs in the future.
