CRUSTAL STRESS AND OIL AND GAS MIGRATION

In this paper are discussed the deformation of rock and the pore pressure under the action of crustal stress. The differential equation and finite element formula for fluid flow in a porous rock are described. The oil migration potentials for Liaohe oil field in North China are calculated based on crustal stress measurements and stress field modelling. The results may provide a basis for oil and gas exploration and development.
