Abstract：By inlluence of tectonic activity of the Cenozo-ic Eastern Kunlun orogenic belt, the Western Qaidam Basin has deformed strongly. With regional structural feature, this part can be divided into compression-shear thrust belts in the piedmont of the Eastern Kunlun range, Mangya depression with the Yingxiong Mountains reverse structural belts in the shallow layers, and the Dafengshan Salient.The total hydrocarbon resources in the Paleogene-Neogene plateau saline lacustrine basin are about 25 ×108t in the Western Qaidam Basin, among which the area effective hydrocarbon source rock amounts to 53%. This region is a typical hydrocarbon-rich depression with abundant surplus resources and great exploration potential. According to the exploration concept of hydrocarbon-rich depression, combined with the analysis of exploration degree and exploration technology, we propose the inverse structural zones in Yingxiong Mountains, lithologic strata in southwest of Qaidam Basin, the paleo-uplift in the piedmont of Altun Mountains, and the Mangya Depression with the periphery dense oil areas as four exploration fields.
