Preliminary Study on Coal-generating Oil of Eogene System in the Baochu Slope of Xihu Sag,East China Sea

In this paper, the coal-developed condition, organic matter character and hydrcarbon-generated pontential of coals have been investigated, the similarity of geochemical character between coals and oils have been discussed, hydrocarbon-generated characters and hydrocarbon-expelled efficiency have been studied. By studying, coals of the Eocene Pinghu formation are one of important hydrocarbon source rocks. At present, coals of the Eocene Pinghu formation have entered into the best epoch of pool-formed, it made a greater contribution to oil-formed.
