摘要

Abstract

To investigate the characteristics of hydrate formation in oil-water systems

a high-pressure cell equipped with visual windows was used where a series of hydrate formation experiments were performed from natural gas + diesel oil + water systems at different water cuts and anti-agglomerant concentrations. According to the temperature and pressure profiles in test experiments

the processes of hydrate formation under two kinds of experimental procedures were analyzed first. Then

based on the experimental phenomena observed through the visual windows

the influences of water cut and anti-agglomerant on the places of hydrate formation and distribution

hydrate morphologies and hydrate morphological evolvements were investigated. Hydrate agglomeration

hydrate deposition and hydrate film growth on the wall were observed in experiments. Furthermore

three different mechanisms for hydrate film growth on the wall were identified. In addition

the influences of water cut and anti-agglomerant on the induction time of hydrate formation were also studied.
