Abstract: The hydrocarbon source of buried hill in Jianghan basin is discussed by using drilling, logging, seismic and experimental data in aspects of the source feature and conducting system. The study shows that there exists multi-supply of hydrocarbon sources to the buried hill, where the buried hill belts of Qianbei and Tonghaikou are of the best for the source supply, the belts of W ancheng and Xingou take the second place, and the Tianmen buried hill is poor for it. These provide solid bases for the buried hill's hydrocarbon accumulation in this area.

Key words: Jianghan basin, buried hill, hydrocarbon source rock, conducting system
