The Analysis of Fracture and Damage Mechanics on the Wellbore Stability Yong Wang 1,a , Liqiang Tang1 and Yong Yang1 1 College of Civil Engineering, Harbin Engineering University, Harbin 150001, China awangyong3502@tom.com Keywords: natural failure stress; meso-fracture mechanics; wellbore instability Abstract: In this paper, the conception of natural fracture stress in rocks is given according to mesomechanics analysis.
The result is the same as the conclusion which was given by the traditional Mohr-Coulomb criterion in petroleum engineering.
The new method of combining mesomechanics with fracture mechanics is used to study the wellbore stability in petroleum engineering, which can reveal the nature of the rock deformation mechanism and provide theoretical reference to design of the drilling engineering.
