New Progress of Oil and Gas Research in the Tonghua Area, East of the Songliao Basin

The Tonghua region in the east of the Songliao Basin is a high-risk and blank area of petroleum exploration. The unrevealed key problems including the growth of source rocks, hydrocarbon generation potential and oil and gas source and the low exploration degree have constrained the further study of petroleum geological conditions and exploration deployment. Based on outcrop and core observations, geological section survey, trench exploration, high-precision gravity and magnetism and geological survey wells, this work discussed the basic geological conditions, main hydrocarbon source rocks, hydrocarbon generation potential and the oil and gas source.
