Phase-controlled amplitude energy compensation method suitable for seismic pre-stack gather data

The invention relates to a phase-controlled amplitude energy compensation method suitable for seismic pre-stack gather data, belonging to the technical field of oil and gas field exploration, comprising the following steps of: longitudinally dividing a stratum into a plurality of layer sections for independent compensation processing, firstly performing spherical diffusion compensation on each small layer section to eliminate amplitude energy difference in the longitudinal direction; amplitude compensation curves of different seismic facies are calculated by integrating AVO forward modeling and waveform classification methods in the transverse direction, energy compensation of seismic traces of different offsets is carried out based on the amplitude compensation curves of the small layer sections, and true amplitude energy compensation of seismic pre-stack gather data considering seismic facies difference characteristics is achieved. 本发明涉及一种适用于地震叠前道集数据的相控振幅能量补偿方法，隶属于油气田勘探技术领域，该方法在纵向上将地层剖分为多个层段进行单独补偿处理，对每个小层段先
