Abstract: Before the founding of New China, we have only two small oilfields named as Y umen and Y anchang fields. In this case, the theory like "Lean Oil China" was prevalent in the world at that time. After the founding of New China, under the guide of Nonmarine Origin Theory, Daqing oilfield was discovered; with source-controlled theory, several more oilfields such as Dagang, Shengli, Liaohe,Huabei, etc. were discovered; while Bohai bay basin field has been enlarged consistently by means of the theory of multiple hydrocarbon accumulation. All of which makes China become No.5 oil producing country in the world. By the fact that Jurassic natural gas and coal-formed hydrocarbons emerged in northern China, this new gas-generated theory allows domestic natural gas resources to be increased by a big margin. Practices for petroleum exploration showed that China's petroliferous basins have distinct geodynamic fields,from which many new petroleum geologic theories have been derived. Looking back, the development of domestic oil-gas resources depends originally on these new theory in petroleum geology; Looking to the future, China 's sustainable development to search for oil-gas resources is in urgent need of new theories.
