Abstract

The invention discloses a comprehensive hydrate simulation system, which generally includes a negative pressure sample chamber for placing samples, a ring pressure system connected to the negative pressure sample chamber, a parameter measurement system, a constant temperature system, a vacuum system, a gas injection system, and a liquid injection system. , heat injection system, drilling fluid circulation system, back pressure system, data acquisition and processing unit. The simulation system of the present invention can simulate the development of natural gas hydrate in all directions, and can be used for indoor research on the mechanism of synthesis and decomposition of natural gas hydrate in my country's sea area, and to master the different development methods and different development methods in the process of trial production of sea area hydrate. Under the well group conditions, important sensitive parameters that affect the test production, such as reservoir physical properties, temperature, pressure, and production variation rules, provide physical simulation support.

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...
