Abstract

The invention discloses a comprehensive hydrate simulation system and an experimental method thereof. Generally, the simulation system includes a negative pressure sample chamber for placing a sample,and a confining pressure system connected to the negative pressure sample chamber, a parameter measurement system, a constant temperature system, a vacuum system, a gas injection system, a liquid injection system, a heat injection system, a drilling fluid circulation system, a return pressure system, and a data acquisition processing unit. The simulation system of the invention can simulate exploration of natural gas hydrates in all aspects, can be applied in indoor research and synthesis of natural gas hydrates in China sea areas and decomposition mechanisms of natural gas hydrates, and canprovide support for physical simulation of reservoir physical properties, temperature, pressure, laws of yield changes and other important sensitive parameters affecting trial exploration of sea hydrates during the trial exploration processes in different development modes and different development well group conditions.

Description

technical field [0001] The invention relates to the field of geology, in particular to a combination of multiple experiments that can realize hydrate single-phase and two-phase permeability measurement, hydrate gas injection production simulation, hydrate formation and decomposition simulation, hydrate reservoir drilling pollution simulation, etc. Sexual simulation system and its experimental method. Background technique [0002] Since this century, the whole world has recognized that natural gas hydrate is a clean energy alternative to conventional fossil fuels. More than 200 hydrate deposits have been discovered in the world. Based on the current energy consumption trend, only 15% of hydrate mining can be used globally for 200 years. However, the stable temperature and pressure conditions formed by itself determine the particularity of its mining method. In addition, the impact of its mining process on the environment needs further evaluation. Therefore, most of the curr...
