【 摘 要 】

Samples of water-hydrate-paraffin sediments with the regions of different colored were obtained by passing the emulsion of CO2-saturated water into oil through a cooled tubular reactor Each of the regions was characterized by means of powder X-ray diffraction. It was shown that prevailing joint deposition of paraffins and hydrate occurs at some regions; complicated water-hydrate-paraffin agglomerates containing almost no admixture of the colored oil components. The possibility to form these agglomerates should be taken into account in the development of the methods preventing the deposition of hydrates and paraffins under real conditions.
