Numerical Simulation of 3D In-situ Stress in Hailaer Oil Field

On the basis of geological characteristic and actual date analysis of hailaer block, the rational geological model, mechanics model and mathematics model were established. With the method of Finite-element constraint optimization algorithms, the numerical simulation of modern three-dimensional tectonic stress field of the hailaer block has been realized. The level of horizontal maximum principal stress, horizontal minimum principal stress, vertical stress value and the distribution characteristics were calculated, so as to provide a gist for evaluating the space fracture distribution, analyzing the migration and accumulation of oil and gas.
