In rugged near surface area, undulating ground and lateral variation in surface structure can distort the propagation path of reflection, cause the distortion of time distance curve and hence lead to poor image. With the purpose of solving these problems, the authors, based on theoretical study and practical data processing, have developed a new series of static correction methods, which include first arrival statics, enlarging bin statics and correlation automatic residual statics. Case studies show the good effect of the methods.
