Numerical Simulation Study on Coal Bed Methane Development
نویسنده
چکیده
In order to find out the advantages and disadvantages of various development methods of coal bed gas, the experimental block provided by the field is studied, the component calculation model is established by CMG numerical simulation software on the basis of fine geologic modeling. Four development schemes are designed which are depleted development, development of hydraulic fracturing, development of nitrogen injection, and development of carbon dioxide injection respectively. Numerical simulation results are shown that the hydraulic fracturing technology that has good effect in increasing production of conventional oil and gas field is not applicable development of coal bed methane in the experimentation area. As gas injection development program, the scheme of carbon dioxide injection is improved by 11.4 percentage points compared with the development of nitrogen injection. This is related to the strong adsorption ability of coal bed methane to carbon dioxide.

The presence of methane in coal mines is one of the major problems in underground coal mines. Every year, in underground coal mines, a lot of casualties due to outbursts and explosions of methane gas is occurring. Existence of this gas in the mines not only creates a difficult and dangerous situation for work but also makes it more expensive. The release of this gas to the air causes a further ...

متن کاملA Field Study on Simulation of CO2 injection-ECBM Production and Prediction of CO2 Storage Capacity in Un-mineable Coal Seam
Studies have shown that, coal seam, an un-conventional reservoir, is considered as a promising option for CO2 sequestration because of its large CO2 sequestration capacity, long time CO2 trapping and extra enhanced coal-bed methane (ECBM) production benefits. However, unlike conventional reservoirs, gas flow in the coal seam can cause the cleat permeability and porosity change during the inject...
متن کاملAdsorption and strain: The CO2-induced swelling of coal
Enhanced coal bed methane recovery (ECBM) consists in injecting carbon dioxide in coal bed methane reservoirs in order to facilitate the recovery of the methane. The injected carbon dioxide gets adsorbed at the surface of the coal pores, which causes the coal to swell. This swelling in confined conditions leads to a closure of the coal reservoir cleat system, which hinders further injection. In...
