Abstract: In order to ascertain the hydrocarbon accumulation conditions in Yingxiongling structural belt,and to explore the oil and gas exploration field and exploration direction,through the data of oil and gas showed in drilling, organic geochemistry,polarized light microscope thin-section investigation,experimental test,geophysics, oil and gas testing,the geological conditions of oil and gas accumulation were analyzed,and favorable exploration plays were predicted. The results show that on reservoir conditions,multiple sets of source rocks are developed, mainly in the Upper of Lower Ganchaigou Formation of Paleogene and the Upper Ganchaigou Formation of the Neogene. There are three types of oil and gas reservoirs,namely clastic rocks and lacustrine carbonate rocks and diamictite,and three types of source-reservoir assemblages namely integrated source-reservoir type, upper-source and lower-reservoir type,and lower-source and upper-reservoir type. Yingxiongling structural belt has favor-able hydrocarbon accumulation conditions,such as superior source rock conditions,good oil and gas resource foundations,various reservoir types,excellent reservoir performance,good matching between late tectonic acti-vity and hydrocarbon generation and expulsion period,and favorable conditions for continuous oil and gas filling. For favorable exploration areas,the exploration direction of Paleogene clastic rocks(delta front sand bodies)is in Huatugou-Hongliuquan and Youshashan-Gasi areas in the structural belt, and the exploration direction of carbonate rocks is in Yingxi-Youyuangou and gasi-Yuejin areas in the structural belt. The exploration direction of Neogene clastic rocks(coastal beach bar sand)is in Shizigou-Huatugou-Youyuangou-Youshashan-Yingdong and the west areas in the structural belt. The exploration direction of carbonate rocks(algae limestone, mixed rock and lime dolomite)is in Youquanzi-Kate-Huangguamao areas on the east side of the structural belt. The results show that Yingxiongling structural belt has the exploration potential to discover large-scale oil and gas fields.

Key words: hydrocarbon accumulation conditions, reservoir characteristics, diamictite, Ganchaigou Formation, exploration field, Qaidam Basin
