适于CDG凝胶调驱技术的有利条件——以彩南油田三工河组油藏为例

在充分调研了国内外CDG凝胶调驱技术现状基础上，根据彩南油田油藏室内试验评价，1999年在彩南油田三工河组：曲藏进行了6个井组为CDG凝胶调驱矿场试验，取得了较显著的经济效益，当年投入产出比达到了1：3．9，从而证实三工河组油藏适于注CDG凝胶，而且有必要继续实施此项措施以提高油田开发效益。

Favorable Conditions Suitable for Using of CDG Gel Adjusting Flood Technique-an example from Sangonghe formation reservoir of Cainan oilfield

After conducting ample investigation on state-of-the-art application of CDG gel adjusting flood technique both at home and abroad, and based on laboratory evaluation for Cainan oilfield reservoir, a field pilot composed of six well groups for Sangonghe formation reservoir of Cainan oilfield has been carried out in 1999. The economic benefit is significant, the input-output ratio reached 1:3.9 in that very year. It proved that CDG gel injection is suitable for the Sangonghe formation reservoir. In view to increase the benefit result of oilfield development, this measure should be implemented continuously.
