摘要： 着重介绍了如何根据油藏地质特征和开采过程中对油、水运动规律的认识,有针对性地综合运用天然水驱、封隔边底水、适时加密井网、注CDG凝胶调驱等多项技术,使彩南油田三工河组油藏的稳产期较方案设计延长一倍,平均以3.5%的采油速度高速稳产可达10年以上,稳产期平均含水上升率可控制在1.4%以下,油藏的最终采收率由原方案设计的35%可提高至60%以上,不仅大幅度增加了可采储量,而且经济效益十分显著。

Abstract: This paper reviewed how to re-understand in-situ oil and water flowing regularities during reservoir development based on the geologic features in Sangonghe reservoir of Cainan oilfield, and how to comprehensively apply several technologies such as natural water drive, plugging the edge and bottom water, proper infill drilling, CDG gel injection, etc., for making the period of stabilized production prolonged over 10 years at oil recovery rate of 3.5%,that is one more times than original project terms, with average raising water cut to be controlled by less than 1 .4%, and final enhanced oil recovery to be increased from 35% to over 60%. All these can not only be able to increase the recoverable reserves, but also obtain remarkable economic benefits.

Key words: Junggar basin, Cainan oilfield, water drive, stable production period, EOR
