摘要：
The paper used logging data combined with 3D seismic data and interpretation results to carry out multiple well-constrained sparse-spike inversion. Layer of wave impedance corresponding to coal seam is determined by calibrating horizon, and then the thickness of the layer of wave impedance is derived and fitted to the coal seam thickness intersected by drilling, finally the distribution regularities of coal seam in 3-D seismic survey area is found out. Practices have verified that the method produces ideal effect. (C) 2011 Published by Elsevier Ltd.
