煤矿三维地震小断层精细解释方法与技术

Fine Interpretation Method and Technology of 3D Seismic Small Faults in Coal Mines

煤层中小断层常会造成大的安全生产事故,因此小断层的准确预测成为煤炭生产迫切需要解决的问题。通过研究优选断层敏感的地震属性,对各种敏感属性进行全空间分析,结合地震时间剖面和已知地质资料进行断层解释,解决了传统断层解释方法容易造成对小断层解释的漏失问题,有效地提高了小断层的解释精度。

Small and mediumfaults in coal often lead to large safety accidents,so accurate prediction of small faults has become crucial in coal safety production.This paper focuses on the sensitive features of faults,and analyse all the sensitive features in full space.The paper endevors to exlain the faults by seismic time profiles and obtained geological data,which fills the gap that the small faults can not be explained by traditional way,effectively improves the interpretation accuracy of small faults.
