ENHANCE THE STUDIES ON NATURAL GAS GEOLOGY AND FIND MORE LARGE GAS FIELDS IN CHINA

At present, the purpose of natural gas exploration in China is no longer to find the medium\|large gas fields, but large gas fields. Enhancing the quantitative or semi\|quantitative studies on the main factors of controlling the formation of the large gas fields, especially defining the area with gas generating strength more than 20×10\+8 m\+3/km\+2 is an important method of finding large gas fields. The fact that coal generates more gas and less oil is the basic rule. The study on natural gas resource studies in China should change form geological resource evaluation to recoverable resource prediction. China has a recoverable resource of natural gas 11.44×10\+\{12\} m\+3 to 13.32×10\+\{12\} m\+3. The natural gas exploration has much potential. Strengthening the study on high potential gas\|rich area is significant for Chinese natural gas industry. The natural gas geochemistry study should combine with the natural gas geology.
