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.
结果表明，NBR与PA在高温、高剪切作用下，两相界面之间可发生微化学反应，但并不影响动态硫化时两相之间的相态反转过程。
The results showed that there was slight chemical reaction between NBR and PA under high temperature and high shear rate, but the chemical reaction did not influence on the process of phase reversion.
