| Abstract: | Percent of water,temperature and pressure conditions of natural gas hydrate formed in gas pipeline are analyzed. Based on analytical results,a method to predict the formation zone of NGH is given. Four precautionary measures are put forward,that is,separating water,injecting methanol/ethylene glycol,heating pipe and depressurizing. |
