Once hydrates block gas production system，it is difficult to eliminate blockages，often influence run，bring accident indeed. To gas gathering pipelines, It's very important to advance to prediction the beginning location of hydrates formation to inject inhibitor. This study is purport to safely, high efficiency in Gas gathering pipelines. ; In this paper，a hydrate formation thermodynamic model for predict hydrate formation conditions has been formulated based on numerical analysis,chemical engineering thermodynamics，heat transfer theories, etc. By combining the model and dynamics of gas production system，the beginning location of hydrates formation of hydrate formation has been predicted. Hydrate plug forecast software(GGP-NGH 1.0) whose language is Visual Basic has been developed that furnish the foundations for predicting hydrate blocking problems of gas gathering pipelines.
