摘要：The study of characteristics of natural gas hydrate slurry formation and flow with wax crystals and anti-agglomerates, is of great significance for the implementation of hydrate slurry technology in deep water waxy oil and gas fields to solve multiphase flow assurance issues. Based on the experiments of hydrate slurry formation and flow with and without wax crystals in the presence of anti-agglomerates carried out in a high-pressure hydrate flow loop, the variations of temperature, pressure, hydrate formation volume fraction, flow rate and pressure drop were compared and analyzed, and the effect of wax crystals on the characteristics of natural gas hydrate slurry formation and flow in the presence of anti-agglomerates was studied combined with the PVM and FBRM microscopic data analysis. The results indicated that the wax crystals would adsorb on the oil-water interfaces under the action of anti-agglomerates, reduce the reaction area of air-water nucleation and increase the mass transfer resistance of hydrate formation, thus inhibiting the formation and nucleation of hydrates leading to extension of the hydrate formation induction time and reduction of hydrate formation amount comparing with that in the wax free system. The aggregate formation coupling between the wax crystals and water droplets promoted the coalescence with hydrate particles, which increased the viscosity and decreased the fluidity of the hydrate slurry remarkably. The formation and flow of natural gas hydrate slurry with wax in the presence of anti-agglomerates was complex. And, the coupling mechanism between wax crystals and hydrates should be investigated further in the future, based on the existed independent research results of wax crystals and hydrates.
