Jimsar sag covers about 1278 km in the south of the eastern uplift of Junggar basin. It is a half graben depression area in which the west, south and north is controlled by faults (Fig. 1), and is tilting uplift to the east. It deposited Permian, Triassic, Jurassic, the Cretaceous and Cenozoic strata chronologically. The thickness of Lucaogou Formation is about 200 m to 350 m, it is the source rocks in the area, and is also a typical selfgenerating and self-preserving tight oil reservoir trapped strata. There are many achievements have been published since 2010, which involves exploration and development (Kuang et al, 2013, Zhou, 2014, Wang et al, 2014). Most of the researches are aimed at reservoir and hydrocarbon source rocks (Kuang et al, 2013, Wang et al., 2014, Xiang et al., 2014), but the study of reservoir comprehensive analysis is rare. According to the exploration data and test data, the author analysis the characteristics and main controlling factors of tight oil reservoir comprehensively.
