地应力与油气运移
CRUSTAL STRESS AND OIL AND GAS MIGRATION
-
摘要: 本文途述了地应力作用下引起的岩石变形及孔隙压力,给出了孔隙岩层中流体的微分方程及有限元公式。在地应力测量及应力场模拟的基础上对辽河油田进行了运移势场的计算,为油气勘探开发提供依据。Abstract: 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.
