【摘要】 叠前岩性处理技术是以保幅处理为基础,以精确的叠前偏移归位和高精度的岩性属性参数提取为特点,其在吐哈盆地岩性油气藏、隐蔽油气藏研究方面发挥了重要的作用,具有十分广阔的应用前景。该文介绍了岩性勘探中地震资料处理采用的技术方法,包括叠前保幅处理、叠前保真去噪、高分辨率处理、叠前时间偏移等技术,是岩性处理的关键技术手段。更多还原

【Abstract】 Prestack lithological processing technique is based on the amplitude preserve processing, is characterized by the retrieve of accurate prestack offset and high precision lithology attribute parameter. It plays an important role in research of lithological reservoir and subtle reservoir of Tuha basin and has wide application potential. The techniques adopted in seismic data processing of lithological exploration are introduced, including prestack amplitude preserve processing, prestack fidelity and noise suppression, prestack time migration, which are all the key techniques and methods.更多还原
