GU Xian-ji, LIU Ming-de, LI Jun, WU Jian-feng.Comparative mapping of seismic two-dimensional migration profile. Petroleum Geophysical Prospecting, 2 0 0 1,36 (5): 5 5 3 ~ 5 6 2 Based on the previous studies , This paper presents a method that can be used both for workstations and for manual interpretation and that is theoretically feasible and easy to implement. The basic points of this method are: 1 Longitudinal and transverse cross-sections are utilized without discarding any data. 2 The offset section calibration of the horizon does not need to be corrected no matter whether it is in a horizontal formation, a structural high, a structural low or a sloped formation , Can be directly used t0 = 2 H / Va for calibration; 3 using conventional comparison method and unequal time comparison method for cross-section comparison; 4 after the reverse line along the survey to solve the problem of t0 closed at the intersection point of the plan, and then Such as t0 maps and other depth maps (but also for other t0 maps directly for such depth maps)
