Analysis of Low Damage Completion Fluid for Deep Coalbed Methane Wells
Completion fluids with water-sensitive damage are usually used in deep coalbed methane Wells,but such completion fluids have serious damage problems and have adverse effects on the mining efficiency of coalbed methane Wells.In the process of coalbed methane mining,it is necessary to inject liquid into the bottom of the well constantly,which will inevitably cause certain damage to the coal seam.Based on the problems in the process of deep coalbed methane Wells,the common completion fluids in coalbed methane Wells are analyzed and discussed,and on this basis,the corresponding low damage completion fluid scheme is proposed.The analysis results show that the low damage completion fluid can effectively reduce the problems in deep well CBM exploitation.
