井间地震技术的优势在于比地面地震具有更高的分辨率,其作为油气勘探开发中的一项新的应用技术被日益高度关注,而且其技术发展速度非常快。本文在简要介绍井间地震技术新的应用及野外采集方面新的进展基础上,重点描述国外井间地震技术在处理方面的最新发展动态,主要包括波场分离、全波场初至识别、节点层析成像、三维地质建模及三维成像、各向异性特征研究等内容及已取得的研究成果,为从事相关研究的技术人员提供参考信息,为从事地球物理专业研究的人员进一步了解先进的井间地震技术提供帮助。
Crosswell seismic technology has the advantage of higher resolution than ground-based seismic. As a new application technique in oil and gas exploration and development, it has received increasing attention and its technology has been developed very fast. Based on the brief introduction of the new application of crosswell seismic technology and the new progress in field acquisition, this paper focuses on the latest developments of crosswell seismic technology in the field of processing, including wavefield separation, initial arrival of all wave fields, Tomography, three-dimensional geological modeling and three-dimensional imaging, anisotropic characteristics of the content and the research results have been obtained for the relevant technical staff to provide reference information for the geophysical professional personnel to further understand the advanced well Seismic techniques to help.
