APPLICATION OF INJECTION WELL CONTRASTING TEST IN INJECTION PROJECT ADJUSTMENT

Yan Chang-hui

Abstract

Water out is very serious in high water-cut late stage in Shuanghe oilfield development.In order to increase injection efficiency,it is very important to evaluate injection effectiveness accurately.Relationship between production well and injection well have been analyzed by injection well contrasting test.The results had been got that water injection rate is little and injection effect is unhomogeneous.Injection rate of V1,V8,V9,V10 reservoir should be increased.Injection rate of V6 should be decreased.The low permeability reservoir should carried out acidizing.
