| Abstract: | There are some problems in the gas wells of He-8 and Shan-1 sandstone reservoirs in the northern part of Jingbian Gasfield,such as wellbore liquid loading and short period of stabilized production.By means of the SEM,casting slice and high pressure mercury intrusion,the sandstone samples were tested to analyze the characteristics of petrology and pore types.Then the relationships between the characteristics of micro-pore structure and gas well performance are studied,in which micro-pore structure are divide... |
