MAO Jin-gen, LIANG Xiu-wen, YANG Yang-yang, FENG You-kui.Automatic Initial-to-Static Correction of Equal Offsets.Petroleum Geophysical Prospecting, 2002,07 (5): 469 ~ new method. Firstly, it constructs a very large matrix equation about the difference between cannon and time by using the high-precision correlation of the first arrival wave of the adjacent channel in equal offset gathers and then uses the statistical iteration algorithm to solve the static correction of the shot point and the detected point , And use the probability distribution function to determine the exact gun, static correction, and finally use the error correction function to eliminate the gun, static correction error. The actual data processing results show that this method is automatic, time-saving and high precision.
