Control principles of structures and tectonics over hydrocarbon accumulation and distribution in multi-stage superimposed basins

Tarim Basin is taken as an example to address the controls of structures and tectonics over hydrocarbon in the poly-history superimposed basins. Tarim Basin is a large composite and superimposed sedimentary basin developed upon Presinian continental basement and has undergone such three mega-cycles of extension and compression as Sinian to Middle Devonian, Late Devonian to Triassic, and Jurassic to Quaternary. The control effects of structures and tectonics on hydrocarbon in Tarim Basin include six fields: ①The proto-type basins developed during the three periods of extension have yielded three series of excellent source rocks; ②The key periods of geotectonic transformation led to three effective phases of pool formation; ③The superimposed interfaces between proto-type basins resulted in new plays; ④The superimposition of poly-history basins showed different kinds of pool formation; ⑤The neotectonic movement had given rise to a characterization of pool-formation in the latest geohistory on a large scale; ⑥The superimposed geologic framework controlled oil and gas distribution showing a character in sequential and hiberarchy.
