The characteristics and dynamic mechanism for structure deformation of the Yinan gas field of Kuqa basin in northwestern China are presented systematically. The Yishen anticline that the Yinan gas field located at is a vast duplex at great depths that was engendered by four reverse faults dipping to the north in turn, but the Yiqikilike anticline above is a faultpropagation fold that was mainly engendered by Yiqikeleke fault, one reverse fault dipping to the north. The Yishen and Yiqikelike anticlines started to develop since the sedimentary period of Kangcun Formation of Miocene Epoch in Neogene under the influence of the impact between the India and Eurasia continents that happened since the end of Eocene. The processes of structure deformation happened at multi-phases. The anticline and the faults that brought the anticline into forming are composed of 4～6 segments, they extend NEE as a whole, but EW in parts. The direction, which present sinister lateral strike-slip and hold a left rank intersect at a sharp angle, indicate that the main force comes from the stress force of SN. The stress gave birth to the thrust faults and anticline, and the sinister lateral strike-slip component derived from the stress forces bring them turning in the corner.
