摘要

摘要: 考虑水合物的相变、油相的压缩性、频率、虚拟质量力及体系的温度和压力的影响，建立了含水合物油包水体系的压力波速方程.研究结果表明，输送过程中水合物对体系的压力波速影响很大，在水合物分解区域，气体的出现使体系的压缩性大幅增加，压力波速急速降低；反之，在水合物生成区域，体系的压缩性减小，压力波速增大.随油水比、管径、温度的减小，压力波速均呈现减小的趋势；随压力、油相密度增加，压力波速呈现增大趋势；压力及温度通过影响水合物的分解速度，对体系压力波速产生影响.

Abstract: The pressure wave velocity equation for water-oil emulsion flow with gas hydrate in pipeline transportation systems was established in view of gas hydrate phase transition, compressibility of oil phase, influence of angular frequency, virtual mass force and system temperature and pressure. The results show that the gas hydrate has great influences on the pressure wave velocity of the water-oil system during pipeline transportation. In the gas hydrate decomposition region, the emergence of gas increases the compressibility of the system significantly. As a result, the pressure wave velocity falls rapidly. In the gas hydrate formation region, the compressibility of the system decreases, while the pressure wave velocity rises on the contrary. The pressure, temperature, oil-water ratio, density of oil phase, and pipe diameter all have distinct impact on the pressure wave velocity. The pressure wave velocity shows a falling tendency with the decrease of oil-water ratio, pipe diameter and temperature. A rising tendency of the pressure wave velocity occurs with the increase of pressure and density of oil phase. The pressure and temperature have effects on the hydrate decomposition rate, in turn influence the pressure wave velocity.
