Computer simulation of gas pressure and drainage radius for dense boreholes gas pre-drainage in outburst coal seam

2009 4th International Conference on Computer Science & Education, 2009
The computer simulation technique has been widely applied to the mine disaster control field. In this paper, we discuss the use of dense borehole pre-drainage technology as a preventive measure for coal and gas outburst. In order to enhance the pre-drainage efficiency and rationally arrange the borehole, the solid-gas coupled RFPA2D-Gas software is ...

Studies on Improving Drainage Gas Recovery Efficiency of Gas Wells

2018
Nearly forty percent of gas wells in Daqing Oil Field have been producing water, resulting in reduced production and increased cost. Reasonable measures are required to improve drainage gas efficiency of these wells. Based on the influencing factors of drainage gas recovery process, efficiency could be improved in three aspects, including optimizing ...

Characterization and drainage kinetics of colloidal gas aphrons

AIChE Journal, 2005
AbstractThe variation of air holdup and stability of colloidal gas aphrons (CGAs) with stirring time, surfactant concentration [6, 8.1, 10, and 12 mM sodium lauryl sulfate (SLS)], and stirring speed (3500–7000 rpm) was investigated, and an empirical correlation between the air holdup and stirring time was obtained.
