摘要
高精度、高分辨率三维地震技术在我国多数矿区,不仅可以控制落差大于等于5m的断层,而且对大于1/2波长的地质异常体也具有较高精度的识别能力。以淮北矿区某煤矿为例,应用叠前时间偏移二次处理技术、地震属性技术及多属性聚类分析等方法,获得了研究区令人鼓舞的从未有过的对开采有重要工程价值的地质成果,证实了所用技术的先进性以及三维地震资料二次处理解释的必要性。
In the majority of our country's mining area,the high-precision,high-resolution 3D seismic technology can not only control the fault whose gap equal to or greater than 5m,but also has the ability to identify geological anomalies that greater than 1 / 2 wavelength with high accuracy.This paper,taking a mine in Huaibei mining area for example,by using technique methods such as secondary processing of pre-stack time migration,seismic attributes and cluster analysis of multi-attribute,achieves the encouraging geological values that have never been found and have important project exploitation on the study area,confirms the advanced techniques that are used and the necessity of secondary processing and interpretation on 3D seismic data.
