标题(英语)

Three-dimensional integral prestack depth migration method


摘要(英语)

The invention relates to pre-fold depth excursion technology in the data processing of the oil and earthquake exploration. It includes: setting up the depth speed module for the pro-fold earthquake data; designing the observation grating to solve the wave equation which modulates the propagating process of the earthquake wave in the ball coordinate system; the earthquake wave field switch with computed the frequency field is changed to the time field, then to fit the earthquake wave field Green function energy spectrum and get the reaching time and the swing of the max energy; transforming the travel time and the swing field computed in the ball coordinate system to the orthogonal coordinate system; according to the travel time and the swing to get the max energy integral pro-fold depth excursion; analyzing the speed of the image path collection to modify the depth speed module; by iteration to modify the module until the excursion result fit for the precision. The invention provides the self adaptive switch difference grating computing technology to make the difference grating change thin along with the radius, so the limit difference computing precision can be assured.
