摘　　要：本文从两种思路出发 ,对特殊岩性油气藏的共性即储层裂缝进行研究。一是从储层裂缝形成的古构造应力场出发 ,根据弹性力学理论 ,确定并预测储层构造裂缝的组系、方位和密度的三维分布 ;二是从储层的岩性、岩相单元入手 ,弄清储层岩性分布特征与裂缝分布的关系。同时分别对碳酸盐岩储层岩性的平面分布 ,火山岩储层岩相分布 ,变质岩储层岩性和构造应力场分布 ,以及低渗透油藏储层预测及砂体展布进行研究。通过在曙光古潜山及杜家台油层、欧利坨子火山岩及牛心坨变质岩潜山等滚动勘探区块的应用 。Based on the common nature, i.e, reservoir fracture of oil & gas bearing reservoirs with special lithology, two reservoir fracture research thoughts are described in the paper: one is to determine and predict its 3D distribution of system, orientation and density of structural fractures according to the elastic mechanics theory and palaeostress field; and the other is to analyze the relationship between the lithologic distribution characteristics and fracture distribution beginning with reservoirs, lithology and lithofacies units. Meanwhile, other aspects such as lithology distribution of carbonate reservoir, lithofacies distribution of igneous reservoir, lithology and structural stress field distribution of metamorphism reservoir, and the reservoir prediction and sandbody trend of low permeability reservoir are also within the work scope. In addition, sound and proven economic returns and social benefit have been achieved when progressively applied in the exploration of Shuguang buried hill and Dujiatai formation, Oulituozi igneous reservoir and Niuxintuo metamorphic buried hill.
