摘要
通过对试井资料解释所获得的总表皮系数进行分解,得到了反映气层真实损害程度的地层损害表皮系数。采用地层损害表皮系数、措施增产率及损害半径作为气层损害矿场评价参数,以此为理论依据,采用VC++.NET2005在WindowsXP环境下开发出气层损害评价软件。通过对塔里木盆地大北3气井进行了定量评价,结果表明该井测试层段损害严重,通过采取适当的增产措施,消除地层损害表皮后可使产量得到大幅度提高,该软件具有很好的实用价值。
Through the desintegration of total skin factor obtained from explaining the reservoir testing material,skin factor of strata damage which refelcts the true damage degree of gas zone can be obtained.Adopting skin factor of strata damage,measure stimulation rate and damage radius as field evaluation parameter of gas zone damage,evaluation software of gas zone damage can be developed under circumstane of Win XP with VC++.NET 2005.Through quantity evaluation about Dabei-3 gas well in Talimu basin,the result shows that its testing layers have been severely damaged.The output can be enhanced greatly after removing damaged strata skin by adopting proper stimulation measures,which shows that this software has very excellent practical value.
