摘要: Due to the high-pressure and low-temperature exploitation environment, the characteristics of hydrates are directly related to the safety of pipeline transportation, which is an important research topic for deep-sea flow assurance. In this review, six kinds of extensively used experimental equipment and three types of hot computer simulation methods, which are employed to explore the hydrate characteristics under deep-sea conditions, are comprehensively summarized, covering micro to macro research scales. The experimental equipment includes rotational rheometer, flow loop, high-pressure reactor, differential scanning calorimeter (DSC), micromechanical force (MMF) testing apparatus and microscopic morphology observation (MMO) device. The computer simulation methods involve numerical simulation, molecular dynamics (MD) simulation, Monte Carlo (MC) simulation and first-principles calculation. Their advantages and disadvantages are compared in detail, and their basic principles, main applications and the latest research progress are introduced. Some suggestions for future research methods are also provided. This work aims to help readers quickly grasp the characteristics of the most used research methods, choose suitable methods for their study and further expand these methods, so as to advance the development in hydrate research area.
