Abstract: 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 bene- fit 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.
