利用测井资料评价淡水水淹层

Floodedstrata evaluation using log data

本文简要地介绍一种有效地评价水淹层的方法。该方法根据油田地质基础、水驱油特点和水淹类型说明注淡水开发的油田中，水淹层在测井曲线上的显示特征及其基本原理。应用测井资料确定淡水水淹层内地层水电阻率，提高了新钻调整井中淡水水淹层的解释精度。最后用实例说明了这种方法的有效性和取得的地质成果。

n effective method for floodedstrata evaluation is recommended here. Based on geolo-gy background of oil field, waterflooding properties and flooding types , this method showshow waterflooded strata in oil field are reflected on logging curves. Deriving flooded-stratumwater resistivity from logging data improves the interpretation accuracy of the flooded-stratain a newlydrilled adjustnient well. The effectivity and geological effect of this rnethod are il-lustrated in the paper.
