In the past half century, the first round of oil and gas exploitation has been accomplished in China. Numbers of oil and gas fields have been found in Cenozoic terrestrial sedimentary basins in mainland or continental shelf areas. The output of crude oil reached 167 million ton, which is the top five in the world, and the gas reached 241 hundred million stere, which is the fifteenth. That is a great achievement. However, China has to import crude oil from 1993, and the quantity had reached 7200 million ton in 2000, much more than the 1993's 3000 million ton. The situation is worse and worse, which is impacting the China's economic growth. It is forecasted that the gross imported crude oil can reach 1 hundred million ton, and the gas can reach 400 hundred million stere. Where is the escape hatch for the Chinese oil and gas industry? The writer pointed out that according to the tectonic evolvement history of China, Pre Cenozoic sea facies preserved basins still have great potentials. Although the exploration is hard, only if we depend on scientific methods extensively, work as hard as we can, can we make great achievements, find more oil and gas fields. All that we do will stand for the economic growth of our country.
