Gonghe Basin: ANew and Worth-Researching Basin

Abstract

Abstract: Gonghe basin is located in western Qinghai province of China. It is found that its petroleum geologic conditions are similar to eastern Qaidam basin, and it could be a novel domain for exploring biogenetic gas. Well GC-1 drilled in this basin shows that it has Tertiary system with thickness of over 5 000m. Through analysis an comparison of formation, deposition, structure, hydrocarbon generation and indicator with those from Sanhu area in eastern Qaidam basin, it is believed that the similarities occur in depositional env ironment, gas source rock feature and reservoir characteristic, etc., in the two basins. It is suggested that Gonghe basin is also an ideal area for biogenetic gas, the related exploration and studies should be focused on.

Key words: Qaidam basin, Gonghe basin, Quaternary, biogenetic gas
