Qiangtang Mesozoic as the research object, as a means to petroleum system, the the Qiangtang Mesozoic source rocks, reservoir rocks, cap rock, the combination of reservoir oil and gas migration - aggregation - accumulation as a whole system analysis, early oil and gas exploration in the area to reduce the risks and costs of oil and gas exploration and provide an important reference. The main work of this paper, awareness and results are summarized as follows: (1) collection, analysis and research data of a large number of their predecessors in the Qiangtang Basin, on this basis, Qiangtang Basin geological background, deposition, structural, stratigraphic analysis, sorting , comprehensive and understanding. Collection, collation, compared with the Qiangtang Basin belong to the same system Tethyan domain Northeast with the southern edge of the Eurasian continent in the Jurassic period belong to the same passive continental margin environment Karakum Basin, and put them the oil geological characteristics were compared. (3) in a systematic manner, analysis, study the characteristics of the Qiangtang Basin in Mesozoic source rocks. Qiangtang Basin, there are four sets of source rocks widely distributed type for II 1 and the II 2 -type; higher abundance and maturity of organic matter, for mature - mature, some occasional low maturity samples. 4 finishing, analysis, research Qiangtang Mesozoic reservoir characteristics. The Qiangtang Basin reservoirs main distribution layers of Triassic - Jurassic clastic and carbonate rocks. Qiangtang Basin different blocks, different times reservoir distribution and reservoir physical properties were significantly different. The thickness of the reservoir by the the central uplift south, North Qiangtang depression Centre thinning. The western part of the basin is mainly in carbonate reservoirs, mainly the eastern places clastic reservoir. 5 to systematically collect, collate, analyze, Qiangtang Mesozoic caprock. Qiangtang Mesozoic strata, and the as good cover layer mudstone, gypsum and salt rocks in each segment are well developed. 6 to systematically collect, collate the research history of the world of salt tectonics, salt tectonics in the type of salt tectonics. And salt tectonics in the Qiangtang Basin, distribution, characteristics, the Qiangtang Basin salt tectonics traps are mainly developed in the J 2 q, the J 2 b, J 2 x formation, has important implications on hydrocarbon accumulation. 7 Qiangtang Mesozoic stratigraphic section on the relationship of time and space configuration according to the source, reservoir and cap rock, Qiangtang Basin, reservoir and cap rock is divided into four sets of a combination, and the combination of III can be further divided into 3 sets of two combinations. According to the Qiangtang Basin in Mesozoic petroleum systems analysis of geological elements and events, the basic elements of the petroleum system configuration space well and is relatively good relations with various oil in time. Tectonic movement, trap formation time, the temperature of the fluid inclusions, vitrinite reflectance and organic matter pyrolysis peak temperature and basin modeling, data analysis, two oil and gas reservoir and two key moments: one at the end of the Jurassic - Early Cretaceous is a a major critical moment; second after the late Tertiary sedimentary.
