Discussion of H_2S content on gas well hydrate in Jinbian gas field

Jinbian gas main produce layer is lower palaeozoic majiagou formation,which is mainly carbonate reservoir.Output of natural gas contains hydrogen sulfide and carbon dioxide,hydrogen sulphide level in acidic gas field distribution is in big difference,and the existence of hydrate formation is particularly sensitive to the formation of hydrate.In order to study the influence of hydrogen sulphide acidic gas to hydrate formation,aiming at different H2S content in Jinbian gasfield hydrate,we adopts Pipesim software to calculate Jinbian gas hydrate formation.The results show that the hydrogen sulphide has important effect on the existence of hydrate formation.
