The Stress Calculation of Refracturing Based on Damage Theory

Abstract:

To precisely describe the fracture opening and extending during the process of refracturing, in this paper the actual mechanical characteristics of the reservoir before the refracturing has been considered, according to the principle of conservation of energy, the calculation model of the damage stress of the rock around the borehole before the refracturing has been established, and at the same time the calculation model of the fracture veer has been established , then the well A in Jilin Oilfield has been chosen to calculate and analyze, the calculation results demonstrate that the corrigendum between the actual results and the calculation results is 0.2%, which are very anastomosing.
