Abstract Large-scale surface oil and gas geochemical prospecting and borehole geochemical exploration were carried out in Qaidam Basin, and the results show that oil and gas geochemical exploration is of good indicating significance in search for oil and gas fields within the basin. An integrated oil and gas accumulation geochemical anomaly model dominated by circular or semi-circular halos has been established. The oil and gas geochemical exploration techniques are effective in oil and gas prospective evaluation and drilling prediction in the new exploration of the basin, and are also valuable in finding borehole oil and gas layers and oil and gas showing beds. It is thus concluded that the oil and gas geochemical exploration techniques have broad application prospect in Qaidam Basin.
