STUDY ON COALBED INTERPRETATION USING DYNAMIC CHARACTERISTICS OF REFLECTED WAVE

Based on the geological model of coalbed splitting,merging and sedimentary gap,the forward computational model is established.The dynamic parameters of coalbed reflected wave are extracted using the computer technique.Studying the characteristics of seismic waveform corresponding to the above geological phenomena,and through inversion,the coalbed and its thickness are studied.The effects are better based on the drilling verification.
