摘要
不同低渗透油藏的开发特征表现出的差异与岩石物性、复杂的孔隙结构密切相关。采取恒速压汞方法,讨论储层各微观参数与地层渗透率之间的相互影响。低渗透岩石具有独特的微观孔隙结构,喉道半径低,孔喉比大,喉道形状复杂是渗透率低的本质原因。
The different development feature of various tight reservoir are owing to the complexity of petrophysics and pore structure.About the correlative grade between microscopic parameters and formation permeability by constant speed mercury injection are discussed.The microscopic pore structure of tight rock is very distinctive,the reason that caused low permeability are low throat radius,great pore throat rate and complex throat structure.
