Résumé

The stability of water in oil emulsion is an important factor affecting the blockage of the oil -destabilizing system. Many studies preparing emulsions have used crude oil as oil phase, but the components of crude oil are complex. In the different types of crude oil, even the different batches there are not the same in the composition. In this study, the mineral oil was used as oil phase, and two kinds of non-ionic surfactant (Span80 and Tween60) were mixed as surfaces active components. The stable water-in-oil emulsion without any ion was prepared with different volume fraction of deionized water (30 and 50vol%), different concentration of surfactant (1wt% and 5wt%). The high- pressure differential scanning calorimetry (DSC) was used to measure and analyze the thermal characteristics of methane hydrate formation and dissociation circulation in emulsion. The thermal effect of methane hydrate (and/or ice) formation and dissociation in different emulsions may be observed in the corresponding curves, and the effect of hydrate formation/dissociation on the stability of different emulsions can be analyzed through the peak of the curves.
