Abstract:

 In order to understand tight oil comprehensively, learn the successful development experiences and then promote the development of tight oil in our country, this paper analyzed and compared the geological characteristics of Bakken Formation, Eagleford Formation and Cardium Formation in North America. From the aspect of the convenient reserve calculation, more reasonable tight oil definition was put forward, and the types were divided systematically. The study results show that tight oil is an unconventional light petroleum accumulation in tight sedimentary rocks, including tight source rocks （mudstones） in place in a free or adsorbed state and tight sandstones and carbonates interbedded with or adjacent to source rocks（Bakken Formation and Eagleford Formation）, as well as the reservoirs which have not been developed with conventional technology （Cardium Formation）. The reservoir permeability is extremely low and the reservoir oil can’t achieve economic recovery unless using horizontal well and multistage fracturing techniques. Among the three tight oil reservoirs, tight oil resource of Bakken Formation is the largest and mainly occurs in the tight sandstone, of which the permeability is between 0.01 mD and 1.00 mD. Tight oil resource of Cardium Formation comes the second, and the lithology is mainly sandy mudstone and the permeability is between 0.1 mD and 10.0 mD. Eagleford Formation has the minimum amount of tight oil, and this kind of tight oil mainly occurs in the tight limestone and the range of permeability is 0.000 001 mD to 0.000 100 mD.
