Analysis of Wellbore Instability Law of Shale Formations by Porothermoelastic Mechanics Model

Ma Tianshou;Chen Ping;State Key Lab. of Oil & Gas Reservoir Geology and Exploitation,Southwest Petroleum University;  
Based on the continuous mechanics of porous media and considering the thermo-hydro-mechanical(THM)coupling of anisotropy shale,the porothermoelastic mechanics basic equations of anisotropic porous media and the mathematical model for the borehole stability analysis of shale formation are established. The numerical procedures to solve the problems have been compiled by MATLAB,and analyzing the characteristic of time-varying pore pressure,formation temperature,stress distribution and borehole stability around borehole under three different coupled modes,that is hydro-mechanical( HM) coupling,thermo-mechanical( TM) coupling and THM coupling. The results indicate that the calculation results of numerical solution and analytic solution are in good agreement(the error is 0. 028%),and the enlargement ratio of borehole in example well are in consistent with the actual situation,the correctness of the model and method in this paper are verified. The changes of temperature and pore pressure have a larger influence on stress distribution around borehole,formation temperature decrease and pressure build up in borehole are in favor of borehole stability,and the rising of pore pressure is adverse to borehole stability. The borehole stability of shale formation has a significant time-varying effect,with the time increasing of drilling formation,the area of borehole instability and the hole-size elongation ratio increase gradually. The analysis method of porothermoelastic mechanics can be available for analyzing the law of borehole instability in different time,and it also can provide a scientific calculated means and methods for solving the shale borehole instability.
