摘　　要：随着多分量地震勘探技术的发展,多波AVO分析技术在识别储层特性、提高油气预测成功率方面受到人们的广泛关注。本文针对松辽盆地北部兴城地区的地质特点和油气勘探、开发需求,在XS1井井深3000m以下应用多波AVO分析技术进行砂砾岩、火山岩含气储层的识别研究。首先依据该井含气井段的实际井资料,建立了本区砂砾岩、火山岩含气储层的多波AVO模型,通过正演模拟,确立PP波和PS波在AVO道集上的特征。在此基础上,对过XS1井的M1地震测线进行多波AVO处理和分析,表明此法用于气层的识别结果与正演模拟结果一致,而且PS波AVO分析在识别该区气层方面比PP波具有更明显的优势。Along with the development of multi-component seismic exploration technique,multi-wave AVO analysis is paid widely attention to by the people in aspects identifying the reservoir characters and raising the successful rate of petroleum prediction.In accordance with the geologic feature and requirement of petroleum exploration and development in Xincheng area of northern part of Songliao basin,the paper carried out the study on identification of sand/gravel and volcanic gas-bearing reservoir in 3000m well dep...
