Application Effect of Artificial Reinjection Water Facilities in Deep Coalbed Methane Extraction in Southern Wuxiang Research Area
The exploration and development of deep coalbed methane has increasingly become a focus of attention for domestic unconventional natural gas researchers and related enterprises.Deep coal seams generally have the characteristics of fragmented coal quality,deep burial,low porosity,low permeability,and high maturity.Frequent powder discharge during mining can cause pump jamming,rod breakage,and other malfunctions and shutdowns.Based on the geological characteristics of coal reservoirs in the Wuxiang South research area and the problems existing in drainage,the author has achieved feasible practical results through long-term research on the method of implementing drainage with screw pump equipment and manual reinjection water.The use of artificial reinjection water facilities has the following advantages:maintaining continuous and stable operation of drainage and production equipment.Low operating costs.Easy to operate.The recovery time is fast,and the gas volume is basically not affected.The use of artificial reinjection water facilities provides a relatively suitable solution for the stable and continuous production and operation of coalbed methane in the Southern Wuxiang research area,which is worth widely promoting and applying in deep coalbed methane extraction equipment.
