STUDYING OF THE PROPERTIES OF CLAYED HYDRATE-CONTAINING SAMPLES USING HEAVY WATER BY THE DATA OF NMR RELAXOMETRY METHOD
A model of synthetic hydrates in a mixture of quartz pellets with kaolin clay is considered using by tetrahydrofuran solution based on distilled water and heavy water. The dissociation of tetrahydrofuran is investigated under atmospheric pressure. The analysis of the NMR-characteristics of tetrahydrofuran hydrate in a clayed sand is performed. The stages of hydrate dissociation excluding water contribution are established and it is shown that the NMR-relaxometry method is sensitive to the clay content. The obtained results allow us to simulate the processes of hydrate formation in real rocks and study their physical characteristics.
