摘　　要：调查研究了国内外有关致密油的定义及描述现状,提出了相应的解决思路。基于开发方式上的统一认识,结合致密油特征,从方便开发实践的角度,致密油储层物性上限参数可统一应用空气渗透率表征。基于该研究结果,可将长庆油田、珠江口盆地、延长油田、青海油田、车排子油田车67等致密油藏储层渗透率上限确定为0.25,0.30,0.50,0.25和0.10 mD。This study systematically investigates definitions and description of tight oil reservoir at home and abroad. Based on the consensus about development scheme and the characteristics of tight oil, the upper limit parameter can be unified as air permeability of rock, from the perspective of facilitating exploration and development practice. Based on the experimental results, the upper limits of permeability can be determined to be 0.25,0.30,0.50,0.25 and 0.10 mD in peripheral reservoirs of Changqing Oil Field, Pearl River Mouth Basin Oil Field, YanChang Oil Field, Qinghai Oil Field, and Chepaizi Oil Field.
