A hydrate environment simulation device

Abstract

The invention discloses a hydrate environment simulation device. The hydrate environment simulation device comprises a negative-pressure sample cavity for storing a sample, a steady-state measuring device for heating the sample, a parameter measurement system for measuring parameters of all experimental processes, and a data acquisition and processing unit for controlling the experimental processes. According to the hydrate environment simulation device, development of a natural gas hydrate can be simulated all-directionally, and aqueous vapor transport in a hydrate formation and the gas production rate of a hydrate reservoir under decompression and thermal recovery conditions are researched. The hydrate environment simulation device can be used for indoor research of synthesis and decomposition mechanisms of the natural gas hydrate in sea areas in China, and provides support in the physical simulation aspect for grasping important sensitive parameters such as the reservoir physical property, temperature, pressure and yield change rule which affect producing test under different development modes and different development well group conditions in the sea area hydrate producing testprocess.

Description

technical field [0001] The invention relates to the field of geology, in particular to a hydrate environment simulation device which can provide an environment for hydrate formation, decomposition and exploitation. 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 current research on hydrate mining is still in the stage of laboratory physical simulation and numerical simulation, except for the trial production of a single well or a single well group in a ...

Problems solved by technology

[0007] The current research equipment can only be developed in one aspect, such as only studying the decomposition process of hydrate, or only studying the formation process of hydrate, etc., and cannot provide a simulation device that meets the requirements of all experimental environments
