Abstract

This invention disloses a combining method for desalting seawater and exploiting sea natural gas hydrates including: building an exploitation well, a level well and a collection well, building a floating platform on the sea, a sea desalt device and a natural gas hydrate exploitation device, desalting sea water, analyzing the natural gas hydrates and collecting the natural gas. This invention comprehensively utilizes the thick brine generated in the process of sea water desalting and uses it in the decompound and exploitation of natural gas hydrate to reduce the comprehensive cost.

Description

technical field [0001] The invention belongs to the technical field of resources and environment, and relates to natural gas hydrate exploitation technology and seawater desalination technology, in particular to a joint production method of seawater desalination and marine natural gas hydrate exploitation. Background technique [0002] Energy crisis and water shortage are the two most prominent problems faced by many countries in the world today in the process of economic and social development. The research and development of new alternative energy and renewable energy, as well as the research of water resources and technology research have become the focus and focus of scientific research in all countries, especially developed countries. [0003] Natural Gas Hydrate (Natural Gas Hydrate, referred to as Gas Hydrate) is a non-stoichiometric, ice-like, cage-type crystalline compound formed by low-molecular-weight hydrocarbons in water and natural gas under low temperature and...
