Research on energy-saving and prevention of H-type water hydrate blockage in oil and gas pipelines
摘要
Abstract
To achieve energy-saving prevention of H-type hydrate blockage in oil and gas pipelines,molecular dynamics simulation is employed to construct a comprehensive stability index.The regulatory laws of the structural stability of H-type hydrates are studied,achieving an upgrade from qualitative description to quantitative evaluation of hydrate stability.The results show that cycloheptane can enhance the high-temperature tolerance of H-type hydrates.The index can effectively characterize the decomposition behavior of hydrates and provide a reference for risk management and prevention technologies of H-type hydrates in oil and gas transmission pipelines.关键词
