Title:
HYDRATE SATURABILITY CALCULATING AND ANALYZING METHOD IN EXPERIMENTAL AND NUMERICAL SIMULATION PROCESS
Document Type and Number:
WIPO Patent Application WO/2020/215649
Kind Code:
A1
Abstract:
Disclosed is a hydrate saturability calculating and analyzing method in an experimental and numerical simulation process, wherein the compressibility of a gas is taken into full consideration and methane compression factors under different temperatures and pressure conditions are analyzed; furthermore, a solubility calculating and analyzing mode of methane in pure water under different conditions is also provided at the same time. Two analyzing modes are applied to a laboratory dimension simulation hydrate synthesis and decomposition process. The three-phase saturability of a hydrate, methane and water at different moments is calculated in a closed system. According to the method, under the conditions where direct test methods such as resistivity are deficient, the evolution of storage and hydrate formation and decomposition efficiency observation in an experimental process can be effectively revealed, the experiment and simulation precision can be improved, and an important basis and support for hydrate practical exploitation are provided.
