对低渗透、特低渗透和超低渗透油藏进行了重新划分，对超低渗透油藏和致密油藏在概念上进行了区分，对致密油藏成藏、开发特点进行了讨论，指出了巴肯致密油藏和我国普通意义上的低渗透油藏之间的差异。同时，给出巴肯致密油藏开发所采用的关键技术及其在开发致密油藏方面的理论认识，以期对我国开发超低渗透油藏或致密油藏从理论认识及技术等方面都具有一定的参考价值。

The ranges of permeability among low permeability, extra-low permeability and ultra-low permeability reservoirs are redefined, and the tight oil reservoir and low permeability reservoir are distinguished. The tight oil formation forming mechanism and development features are discussed, and the difference between Bakken tight oil reservoir and the common low permeability reservoir is pointed out. Also, the paper presents the key technologies and new knowledge of developing tight oil reservoirs in the Bakken play. The new technology and theory of developing Bakken tight oil reservoirs can provide low permeability reservoir development in China with a certain referential value.
