Abstract: Through the normalized processing of well logging responses in different years and different logging tools, this paper presents an effective method for getting lithomechnical parameters based on the conventional logs that are widely applied to oilfield and the rock mechanical features as well as their correlations, followed by error correction, coherent analysis and multivariate linear regression technique. Also, this paper provides the lithomechanical model which could be as a guide to field application for the studied area.
