Abstract：There are good geological and geophysical conditions for airborne magnetic survey in Chaidamu basin because there is no igneous rock in sedimentary formation, snd a little civilization interference in the basin. The urmigrated hydrocarbon from reservoir caused chemical reaction in overburden to form magnetite, which results in magnetic anomaly. The minimum altitude airborne magnetic survey (with large scale and high accuracy) mapped weak magnetic anomaly which covers a large area. It has been proved that the weak magnetic anomaly is related to hydrocarbon aecumulation. This experience can also be used in other sedimentary basins in Northwest China which have analogous geological and geophysical conditions.
