摘　　要：研究中利用有限元分析方法对辽河油田滩海地区进行了三维构造应力场的计算机模拟。研究了地应力场的分布特征及其对油气运移的控制作用 ,并对油气积聚的优势区域进行了预测 。This paper deals briefly with the theory of deformation of porous rock, fundamental formula for fluid flow in a porous rock and the finite element method. The three dimensional numerical simulation of geo-stress field in Tanhai is carried out according to the geo-stress measuring. The three-dimensional geo-stress field is given. It is pointed out that on the whole the high geo-stress is consistent with the high migration potential, and the low potential area is favorable for the formation of the oil field. The result provides some useful information for exploration and development of oil and gas fields.
