| Abstract |
Static correction are very important for seismic survey in rugged exploration areas. A new refraction static correction technique is proposed in the paper. The technique is precise, convenient and effective for short and longer spatial wavelength statics in rugged exploration areas. The technique is composed of 5 steps: first arrival picking, selection of sections in first arrivals for static calculation, thickness and velocity inversion, error decomposition and elimination and calculation of static correction value. Two field examples are included in the paper. |
