As the development of Trias Chang2 reservoir in Zhangqu Block drags on, the amount of water content increases year by year and the damages to casings worsens which leads to severe corrosion and deposits in shafts and a potential diminishing in wells working life. This paper had in response come up with preventive and controlling methods which proved effective in reducing minor well repairs and prolonging wells＂ working life thus improving the economic benefits of the oil field
