七棵树油田油水两相渗流规律研究

Study on Oil-water Two-phase Fluid Flow Law in Qikeshu Oilfield

在油水相对渗透率实验数据的基础上,对该区油水两相渗流规律进行研究,总结该区油水相对渗透率随含水饱和度变化趋势,注水开发过程中含水率、含水上升率随采出程度变化规律,相对采油(液)指数随含水率变化趋势,进而判断该区润湿性,评价采收率、产能、稳产潜力及中高含水期的提液能力等。

Oil-water two-phase fluid flow law was researched according to experiment dates of oil-water two-phase fluid flow permeability. Oil-water two-phase fluid flow permeability variation trend with water saturation was summarized, as well as average water cut and water cut increasing rate variation trend with production period, relative productivity index variation trend with average water cut. On basis, the wettability was estimated, and oil recovery, oil field production capacity, stable yield potential, extract ability during high water cut period were evaluated.
