A method for degassing gas-bearing pools includes drilling and sealing of the mouth of degassing well, well casing with perforated tube to which suction tube is installed, this is connected through degassing pipeline to vacuum pump. Preliminarily the lower working section of the suction tube is made perforated, with tightening it from case pipe at the level of contact with inoperative section. Pressure of motion of sucked gas in well is set. In the following process of suction respective zones of rarefaction in working section are formed, with control of the value of current pressure, with comparison to set pressure and in the case of deflection with control through change of the value of rarefaction zone. This results in increase of effectiveness of degassing. |
