Gamma density logging method is used to measure the volume density of the cement sheath.

伽马密度测井测量水泥环体密度，这种测量方法与固井各胶结面状态无关。

The dual-detector density logging response relation has been widely used, but some factors have been neglected.

现在使用的双源距密度测井响应关系较理想化，很多影响因素都忽略了。

Qualitative identification and quantitative evaluation of fracture and pore have been conducted by use of interval acoustic transit time, litho-density logging, combined with core analysis.

还利用声波时差、岩性密度等测井技术，结合岩心分析，开展裂缝、孔隙的定性识别和定量评价；
