AVO技术是一项利用振幅随炮检距变化特征分析识别岩性和油气藏的地震勘探技术,可以更为合理地提取隐藏在地震信息中的岩性参数,预测岩性和烃类。近年来,AVO技术形成了包括高保真、保幅地震资料处理技术,异常振幅识别技术,模型正演及弹性反演技术等技术系列。随着AVO技术研究应 AVO is a seismic exploration technology that uses lithology and reservoir identification to study the characteristics of amplitude and offset variation. It can extract lithology parameters hidden in seismic information more reasonably and predict lithology and hydrocarbon. In recent years, AVO technology has formed a series of technologies including high-fidelity, preserved amplitude seismic data processing technology, abnormal amplitude identification technology, model forward modeling and elastic inversion technology. With AVO technology research should be
