摘　　要：从特低渗储层渗流机理研究出发,分析了其渗流规律——非达西渗流特征;根据储层中上覆岩石围压变化,通过室内试验表述了其对渗透率伤害。研究提出了改善渗流特征的注水条件、井网优化和压裂对策,可以有效提高这类油藏的开发效果。By studying the percolation mechanism of super-low permeability reservoir, the paper analyses its law-non Darcy percolation characteristics. Based on the change of stress from upside rock in the reservoir, the damage to permeability is illustrated by the lab experiment. The study of it proposes the injection condition, well net optimism and fracture strategy to upgrade the percolation property that can raise the development result of this kind reservoir.
