英文摘要In this paper, Hamilton method is introduced to study the characters of how seismic reflective traveltime of the same reflective point varies with the offset, which is important in prestack seismic processing. Since the traveltime is a function of source location, receiver location, setoff angle and receiver angle of the seismic ray, the Hamilton canonical equation that describes the CRP trajectory in complex media can be proposed after analyzing the differential characters that common reflection travel time varies with the source location. As an example, the Hamilton canonical equation has been analytically derived for the traveltime function in the linearly varied velocity media is analytical. The trajectories of the points on several typical reflective surfaces are calculated in three different earth model, which has constant velocity, transverse varied velocity or linearly varied velocity. Some characters of Hamilton method can be deduced from the trajectories. It is the first time for Hamilton method is introduced to describe the CRP trajectory, which gives a new way in this field.
