注水井验封资料在判断报废井质量中的应用

An Application of Injection Well'Checking Sealing Data in Determining the Quality of Abandoned Well

对于报废井 ,其报废质量的好坏将对其周围井的正常生产带来影响。为了检验报废井是否达到报废目的 ,本文提出了一种利用注水井的验封资料来定性判断同井场报废井报废质量的简便方法。该方法既可通过验封资料判断注水井各级封隔器的密封性 ,又可利用该验封资料来定性判断同井场报废井中是否存在层间窜流 ,是一种经济、实用的检查报废井质量的新方法。

To abandoned well,its good or bad quality has an effect on the wells around it.For the purpose to test whether the well is to be abandoned or not,the paper gives a simple method to judge the abandoned well'quality in the same well site by the means of injection well'check-sealing data.This method can not only decide the sealing property of every grade packers in injection well through check-sealing data,but also determine if the interzonal communication is exist in the abandoned wells of the same well site.That is an economical and practical way to inspect the quality of it.
