Research in the Propping Agent for the Hydraulic Fracturing Cracks for the Methane Extraction from the Massive Coal Seams

摘要

The success of coalbed methane field development is largely determined by the effectiveness of using special gas production stimulation methods. The need of implementing of such methods is driven by features of location and movement of methane in the coal body. The process of hydraulic fracturing as the most frequently used method for the stimulation of a well production capacity at commercial production of methane from the coal seams is described. The use of quartz sand as a propping agent for the hydraulic fracturing cracks when extracting the methane from coal seams is proved. The information about the companies using quartz sand for hydraulic fracturing in Russia is provided. The mineral resource potential of the Kemerovo region in sand mining is marked. The results of the researches in sand from the deposits of the Kemerovo region as the proppants for the hydraulic fracturing cracks are shown. The received results allow to draw a conclusion on high prospects of use of local sands at extraction of coal bed methane in Kuzbass.
