Abstract:

Relatively high price of natural gas has been regarded as the key factor to affect the fast and sustainable development of natural gas. After the reserves of unassociated gas being increased fast, it is asked to adjust the main direction of  natural gas development to deepen exploration of natural gas in the two basins in the central part and the regions (eg.the areas of northern and southern Tians han mountains) near pipelines in China.It is suggested that tight gas reservoirs  should be enhanced to explore,especially in rolling development. Meawhile, much investment to the offshore regions should be obtained, and more attention to the  unassociated gas reservoirs, distributed in the mid-light crude oil-bearing areas in Bohai Bay ,should be also paid, excepting further exploration in the northern part of South China Sea and East China Sea.These offshore regions can be considered as a strategic one to be exploit according to different  geological  backgrounds both uplifts and depression in northern and southern Huanghai. In the sake of economic value of the medium-minor gasfields in eastern China is  high,if they are as the underground reservoirs of gas (oil) ,they will certainly play a more important role in the future.
