At present, the main energy resources in the world are oil, natural gas, coal, uranium, etc., which are commonly referred to as conventional energy resources. Otherwise, resources called unconventional energy resources are predicted to have enormous potential exists. Among the unconventional energy resources, as corresponding to the natural gas, these include shale gas, coal bed methane, tight gas, methane hydrate, water-soluble gas, and others. In recent years, owing to the advances in technological development, research and development of unconventional natural gas have been activated. In particular developed, such as shale gas in North America, will have a great influence on the gas supply in the world in the future.
This paper will discuss the resources situation of natural gas in China, which includes unconventional gas, development situation and supply potential. In China, there is a fascinating natural gas resource, especially the unconventional natural gas, which has a promising potential. With the development of geological survey, resource of natural gas is expected to further expand. The development of natural gas is highly expected. China has already grasped the developed technology of conventional natural gas and tight gas. On the other hand, unconventional natural gas is in the initial exploitation. As far as the development track record, China's companies still can not catch up with the development capabilities of the companies of United States. Therefore, the innovation and cooperation with foreign companies have become necessary. In China, due to the rich natural gas reserves, the implementation of progress and preferential policies of development technology, the development of unconventional natural gas are in the accelerated development. At present, unconventional natural gas has become the supplement for the conventional natural gas, and may become an important source in the future. By these things, it is considered that the unconventional natural gas will bring a major change to China's energy industry.
