管道内水合物堵塞块移动速度计算模型的建立与分析

摘要

针对管道内水合物降压法解堵过程中存在的问题,建立了管道内水合物解堵过程中水合物块的移动速度计算模型.算例分析表明,该模型可有效地预测水合物块移动速度与移动距离之间的关系,避免发生水合物块对下游管线或设备的冲击风险,为管道内水合物堵塞事故的处理提供指导.%In view of the problem occurred in hydrate blockage removal in pipelines by pressure reduction method,a model is established to calculate hydrate plug moving velocity during hydrate blockage removal process.Analysis of examples indicates that this model can predict the relation between hydrate plug velocity and its moving distance,which can avoid impact on pipelines or devices by hydrate plug and provide guidance to disposal hydrate blockage accident.
