Abstract : Wennan oilfield is characteristic with shallow embeded ,low permeable and complicated fault block, the reserve with low permeability covers over 60 percent in total reserves, so the quality for injection water is quite high. The injection water hardly swept up the low-permeable formation due to nonstandard injecting water quality before 1995, which led to quite difficult to develop the low permeability reserve and to form severe corrosion in injecting system, so the huge loss is inevitable for oilfield development. After 1995, through technicians’ continuous summarization and creation in practice , we researched one new water disposal technology : Clean & Dirty Water Mixture Disposal Technology. Its main feature is to pre-mix and react for clean and dirty water resource, subsequently form a stable water quality system so as to resolve the corrosion and deposition problem for two unsuited quality water in injection, and realize the water quality to meet operational standard. This technology has so many advantages including low cost, high automation, easy operation, stable water quality and so forth, the water quality index after disposal reaches A1 l……
