Abstract: It is proved that Tazhong region is basically provided with necessary factors responsible for the richness in hydrocarbon after a comprehensive discussion of regional and petroleum geology condition.The Tazhong Uplift takes its shape early, and grows steadily in later period. Huge to large structures develop well in Lower Paleozoic deposition.A series of sources, reservoirs, seals and their compositions are covered by carboniferous mudstone.The unconformity lies in Lower Carboniferous is the most important role in the respects of tectonic evolution and generating and being buried by hydrocarbon.The speciality of tectonic evolution and richness, varied types of oil pool in Tazhong region resulted in a regional and widespread system of oil pool composition under the seal of Carboniferous mudstone.Oil and gas exploration in Tazhong region should be approached from a consideration as a whole, and the synthetic three-dimensional alternated exploration is needed emergently.

Key words: Tazhong, petroleum geology, synthetic three-dimensional, integrated exploration
