| Research on Coal Reservoir Pressure of some Mine Areas in North China |
| The pressure of coal reservoir,an important parameter in the development of coalbed methane,can be determined through well test.The well test information of some mine areas in North China shows that the pressure of coal reservoirs vary in a wide range.The main influencing factors are tectonic stress,height and burial depth of groundwater,the mineralization degree of groundwater and so on.When the coalbed methane saturation is constant,the pressure of coal reservoir has a relatively great influence on the methane and water production rates in the early period of coalbeed gas wells. |
