The study of tight oil is one of the key research areas of the Daqing Oilfield in recent two years,and its proportion is growing in the incremental reserves and production.In2014,the tight oil reserves accounted for 65.5%in the incremental oil reserves of middle-shallow layers in the north of the Songliao Basin,thus the study of tight oil has received more and more attention and becomes one of the most prominent researches in the field of petroleum geology.It is imperative to develop an evaluation standard
