Description

technical field [0001] The invention belongs to the technical field of coalbed methane exploitation, in particular to an experimental method for continuous separation of gas-containing coal and water mixture. Background technique [0002] Traditional energy resources have gradually been unable to meet the current excessive consumption of energy resources. The development and utilization of coalbed methane can alleviate the current world energy shortage. The development and utilization of coalbed methane can not only greatly reduce the accident rate of coal mine gas and reduce greenhouse gas emissions from mines, but also generate huge economic benefits as a clean energy source, which is of great significance for ensuring energy security and reducing foreign dependence on natural gas. [0003] The extensive development of tectonic coal and the abundance of tectonic coal and coalbed methane resources are the distinctive features of coal and coalbed methane resources in China. ...

Problems solved by technology

However, during the development process, a large amount of gas-containing coal, water and gas mixtures are produced. How to achieve efficient, continuous and rapid separation of gas, water and coal is an important theory and technology for in-situ CBM horizontal well cave pressure relief mining. question

However, because structural coal development areas are restricted areas for in-situ coalbed methane development, there are no in-depth reports on the use of in-situ coalbed methane development technologies and methods, and there are no research reports on the efficient, continuous and rapid separation of gas, water, and coal. The two-phase or three-phase mixture separation method is difficult to realize the efficient, continuous and rapid separation of gas, water and coal produced by the pressure-relief mining of in-situ coalbed methane horizontal well caverns due to their specific objects.

[0004] The efficient, continuous and rapid separation of a large amount of viscous mixed fluid containing gaseous coal, gas and water through in-situ coalbed methane horizontal well cave pressure relief mining in structural coal development areas is the key to realizing efficient coal mining, gas recovery and water resource recycling. However, there are many obstacles to determine the separation scheme of gas-water mixed fluid in field operation, high cost and high risk factor, and it is impossible to quickly determine the specific separation scheme; The effective separation and collection of a large amount of viscous gas-containing coal, gas and water mixed fluid produced by in-situ coalbed methane horizontal well cave pressure relief mining is very important for the study of structural coal development areas to achieve successful in-situ coalbed methane mining. It provides important theoretical guidance for in-situ coalbed methane horizontal well cave pressure relief mining in structural coal development areas, and has important theoretical and practical production guiding significance for the development of coal bed methane in structural coal development areas
