 通过对平均能量法分析研究和标准化处理，提出反映第域界面胶结情况的胶结指数，从而
使第域界面的胶结质量评价定量化；并综合利用伽马密度测井、变密度测井和自然伽马测井，制定出固
井第域界面解释评价标准使固井质量评价精度大大提高。

This paper proposes a cementation factor of the second
interface cemented case by means of averaging energy method
reseached and standardization handled. So the second interface
cement quality is evaluated quantificatly,and the second interface
evaluation is developed by producation utilization gamma density
logging,variable density logging and gamma ray logging,and the
primary cement evalation accuracy is raised.
