Research on energy-saving and prevention of H-type water hydrate blockage in oil and gas pipelines
为实现输油气管道H型水合物堵塞的节能防治,采用分子动力学模拟,构建综合稳定性指数,研究H型水合物结构稳定性的调控规律,实现水合物稳定性从定性描述到定量评价的升级.结果表明,环庚烷可以提升H型水合物高温耐受性.该指数能够有效表征水合物分解行为,为油气输送管道H型水合物风险管控与防治技术提供参考.
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.
