Reasonable injection pressure and rate can improve the development response of gas injection and the recovery factor of carbonate buried hill reservoir.

Based on a thermodynamic model of gas_liquid equilibrium, the variation of phase behavior in a volatile oil system during gas injection has been investigated.

For the purpose of ascertaining the time of gas charging and the formation period of gas reservoirs in the Upper Paleozoic of Sulige Gas Field,the samples of fluid inclusions from this field were tested and analyzed using the more advanced testing apparatus and techniques.
