Abstract: The tectonic domains with active crustal movement may include circum-Pacific tectonic zone, oceanic ridge tectonic zone and northern continental tectonic zone nowadays, in which there exist active natural earthquakes, removement of deep faults. Following a natural earthquake, oil shows could always be found on the surface. This is reason why the oilfields in USA are mostly distributed between ruinous earthquake belts, while the oilfields discovered in China are dominantly associated with active fauling. It is confirmed that more than a half of oilfields in the world is distributed within circum-Pacific and northern continental tectonic zones，indicating that the distribution of oilfield has internal relations to crustal movements, natural earthquake in a force of exo-drainage of the eath's deep fluid or material that may contain crude oil or hydrocarbon gas. Therefore these active tectonic zones in nowadays active crustal movement will be as important targets for petroleum exploration.

Key words: natural earthquake, active tectonic system, oil and gas field, distribution
