As gas field entered into the waterthrough development period, frozen plugging phenomenon of gas hydrate occurred at wellhole, wellhead and ground process equipments of some gas wells. This phenomenon seriously affected the production and sales. In order to speed up gasfield development process, improve gas production techniques, and resolve the negative effects of hydrate frozen plugging on gas reservoir development, researches were conducted on the static and dynamic influencing factors of gas hy-drate formation, hydrate inhibitor evaluation and matching technology. Through researches and field tests, the results effectively in-hibited the gas well hydrate formation, solved openning rate of the gas well due to the frozen plugging of gas hydrate, and played an important role in protective development and EOR of gas wells.
