Evaluation and potential discussion of hydrocarbon source rock in north margin of kashi sag,tarim basin

Based on the fieldwork and geochemical analysis, this article discusses the source rock in north margin of Kashi sag. According to the combined analysis of thick, organic matter, type and maturity of source rock, the potential for hydrocarbon-generation of Carboniferous-Permian source rock in north margin of Kashi sag is not impressive, and the Carboniferous-Permian source rock can not be the main source for the large-medium sized gas field and the Jurassic source rock is the main source for the natural gas of this region.
