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 self- generating and self-preserving tight oil reservoir trapped strata.展开更多
文摘1 Introduction Jimsar sag covers about 1278 km2 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 self- generating and self-preserving tight oil reservoir trapped strata.
