Study of Exploration Technology Model of Coal Bed Methane Enrichment Region by CSAMT
Coal bed Methane (CBM) has its own particularity in occurrence,accumulation,preservation and other aspects;in order to reduce the cost of CBM exploration,In this article,the similarities and differences between CBM and conventional natural gas was Discussed in detail,and summarized the close relationship between CBM and groundwater,the favorable geological model of CBM enrichment was analyzed,and combined with the Controlled Source Audio Magnetotelluric sounding (CSAMT) principles,we proposed using CSAMT method to explore the CBM enrichment region.According to the target stratigraphic electrical structure to deduce the inheritance relationship between each stratigraphic and combined the favorable geological model of CBM enrichment to forecast the CBM enrichment region.In this paper,the CBM exploration technology mode by using CSAMT method was proposed,by using non-seismic exploration technology for CBM exploration,can effectively reduce the cost of CBM exploration;and provided an important and economic way for CBM exploration.
