Evaluation on Effect of Water Injection on Well 4067 in Fuchang Area

Wayaobao oil production plant is controlled by lithology, bottom water effect, and elastic dissolved gas driving structure. Its recovery rate is 0.55, the decline of production is rapid, and water cut increases rapidly. In this paper, the injection production well network, injection production pressure system and flooding effect were analyzed and evaluated. Comprehensive adjustment method of the water injection was put forward to improve the well network and increase the formation energy according to different flooding problems.
