摘　　要：张渠区块开发三叠系长2油层,随着油田开发时间的延长,含水逐年上升,套损加剧,井筒腐蚀及结垢日益严重,严重制约着油井免修期的延长。为此,从腐蚀、结垢等影响免修期因素入手,探索形成了有效的防治对策。现场推广后,有效降低小修井次,延长了油井免修期,提高了区块经济效益。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
