Abstract

The invention discloses a method and a device for generating reflection angle gathers of common imaging points. The generating method generates a common imaging point reflection angle gather by using a pre-stack time migration method, and the generating method includes: obtaining a slice velocity, where the slice velocity is the velocity of seismic wave propagation in the formation; calculating the incident angle according to the slice velocity, wherein the incident angle The angle is the incident angle of the seismic ray; and the common imaging point reflection angle gather is generated according to the incident angle. The invention solves the problem of inaccuracy in generating the reflection angle gather of the common imaging point in the pre-stack time migration method in the related art.

Description

technical field [0001] The invention relates to the technical field of reflection seismic information processing in seismic exploration, in particular to a method and device for generating reflection angle gathers of common imaging points. Background technique [0002] Amplitude Versus Offset (AVO) technology is widely used in reservoir inversion and prediction of petrophysical properties, which greatly improves the accuracy of reservoir prediction. Compared with post-stack inversion, pre-stack seismic inversion can provide richer inversion information. In addition to P-wave impedance, S-wave impedance, total S-wave density and density can be obtained, and various elastic parameters can be calculated, providing rock Provides a wealth of information for sex and fluid identification and prediction. [0003] The theoretical basis of AVO technology is that the amplitude varies with the incident angle (Amplitude Versus Angle, referred to as AVA). The two have a simple geometric ...
