摘要： 水合物技术在天然气储运、二氧化碳捕集与封存、气体分离和冷能等领域具有广阔的应用前景。自然条件下，水合物普遍存在着生成速率低、应用环境限制多等因素，因此常采用物理法或化学法来改善其工业化生产条件。物理法和化学法具有生成速率高、储气量高的优点，但存在能耗高、设备成本高、环境污染等问题。近年来，电场对水合物的影响及其作用机理吸引了众多学者的关注与研究。本研究综述了学者们在不同电场环境下对TBAB、THF、CH4、CO2水合物生成与分解进行的分子动力学模拟以及实验的研究进展，包括研究条件、作用效果以及电场对水合物的作用机理。从众多的研究结果得出，电场对水合物的生成与分解具有积极影响，有利于实际应用，值得继续研究及探索。

Abstract: Hydrate technology has broad application prospects in the fields of natural gas storage and transportation, carbon dioxide capture and storage, gas separation and cold energy. Under natural conditions, hydrates generally have such factors as low generation rate and limited application environment, so physical or chemical methods are often used to improve their industrial production conditions. Physical and chemical methods have the advantages of high generation rate and high gas storage capacity, but there are some problems, such as high energy consumption, high equipment cost and environmental pollution. In recent years, the effect of electric field on hydrate and its mechanism have attracted the attention and research of many scholars. This paper reviews the molecular dynamics simulation and experimental research progress of TBAB, THF, CH4 and CO2 hydrate under different electric field environments, including the research conditions, effect and mechanism of electric field on hydrate. According to many research results, electric field has a positive effect on the formation and decomposition of hydrate, which deserves further study and exploration.
