| Abstract: | Based on the geological characteristics and thermal evolution of natural gas in Dagang exploration area, this study has classified genesis of natural gas into six categories: biogenetic gas, low-temperature mixture gas, low-matured gas, matured gas, high matured gas, and coal-genetic gas. In addition, this paper has analyzed the distribution and geochemical characteristics of various kinds of natural gas in Dagang exploration area. |
