摘要
With the buried depth increasing, the solubility of natural gas changes in different phases under the synergetic effects of temperature and pressure. Applying solubility regression equation is favor to estimate the boundary of natural gas segregation. There are four accumulation models in China that water-soluble gas is segregated formation water associated with the structure and percolation-related,including lateral phase degassing,fault-diapiric degassing, caprock percolation degassing, structures uplift degassing.
