Research on Monitoring Technology of Influence Range of Coal Mine Hydraulic Fracturing
According to the characteristics of sensitive reflection when transient electromagnetic instrument detect to low resistance object,transient electromagnetic method is adopted to monitor the hydraulic fracturing effect of 7 M6-3 coal seam hydraulic fracturing holes in N1640 South Gas Lane of Songzao Shihao coal mine for test.Intrinsically safe YCS360 transient electromagnetic instrument is Chosen.Field detection indicates: The apparent resistivity of the fracturing bores corresponding coal seam position produces a distance variation ranging from 24.9m to 119.7m before and after fracturing,and there is a big difference in the range of influence of fracturing.Therefore,the transient electromagnetic exploration instrument can effectively detect hydraulic fracturing affect regional distribution,and the result can optimize coal seam fracturing design and provide important reference basis to improve the fracturing effect of coal seam.
