油藏地震识别方法及应用

Seismic Recognition Methods of Reservoir and Their Application

地震资料分析是进行油气田勘探的重要手段,主要包括三维地震、井间地震以及四维地震(时移地震)等。本文分别对这几类地震资料及其原理进行分析,结果表明,三维地震主要应用于油气勘探,可以对储层的岩性、物性进行预测,通过提高分辨率可以达到对小层级别油层的研究;井间地震方法可以提高井间预测的精度;四维地震法是监测油田开发动态的有效手段。

The seismic data analysis is an important means of oil and gas exploration, including three-dimensional seismic, crosswell seismic and 4 D seismic（earthquake shifted） and so on. In this paper, these types of seismic data and their principles were analyzed. The results show that the three-dimensional seismic is mainly used in oil and gas exploration, it can predict the lithology and physical properties, the resolution can be increased; the crosswell seismic method can improve the accuracy of prediction between wells; the 4 D seismic method is an effective tool for monitoring field development dynamic.
