A computational analysis method for hydrate saturation in experimental and numerical simulation processes

摘要

PROBLEM TO BE SOLVED: To obtain a method for calculating and analyzing hydrate saturation in an experimental and numerical simulation process. SOLUTION: The present invention fully considers the compressibility of a gas and realizes the analysis of the methane compressibility factor under various temperature and pressure conditions, and at the same time, the solubility of methane in pure water under various conditions. It provides a computational analysis method and applies two methods to the hydrate synthesis and decomposition process on a laboratory simulation scale for the three-phase saturation of hydrate, methane gas and water at various times in a closed system. Realize the calculation. The present invention can effectively show changes in reserves during the experimental process, observe hydrate formation and decomposition efficiency, and accuracy of experiments and simulations under the condition that there is no direct measuring means such as resistivity. Can provide important evidence and support for the actual mining of hydrates.
