摘要
互均化技术是时间推移地震勘探数据处理的核心步骤，它能有效地消除因时间推移地震数据采集、数据处理流程和处理参数不一致性在时延地震差异剖面上产生的假异常，突出因油气藏开发效应而产生的地震响应差异，使时间推移地震差异剖面的异常对应于油气藏物性的变化。典型的叠后互均化处理技术包括四个基本步骤：①空间校正；②匹配滤波；③振幅平衡；④速度校正。
The cross equalization technology is a key procedure in data processing of time lapse seismic exploration.The technology can effectively remove the false anomalies formed in the time lapse seismic difference section due to the data acquisition and the disconformity of data processing procedure with processing parameters and can protrude the seismic response differences related to reservoir development effect,causing the anomalies in the time lapse seismic difference section to be corresponding with the petrophysical property change in the reservoir.A typical post stack cross equalization processing technology includes the following four basic steps:①spatial correction;②match filtering;③amplitude balancing;and ④ velocity correction.
