三维地震属性技术在湖区的应用效果

Application of 3D seismic attributes technique in lake area

微山湖湖区表层地震地质条件十分复杂,芦苇丛生,三维地震勘探野外数据采集采用自行研制的钻井平台加套管护壁的成孔工艺,沼泽检波器加上加长尾椎,提高了检波器的耦合效果,获取了高信噪比的三维地震数据。资料解释应用了三维可视化、相干数据体、地震属性技术进行三维构造精细化解释,明显提高了地震解释识别地下小地质构造及地震异常体的能力,它完善和发展了三维高分辨率地震勘探技术[1],扩大了地震勘探的应用范围,为解决煤矿开采阶段所遇到的构造、煤层等地质问题提供了一种综合应用的解释方法,在湖区的勘探开发中,取得了明显的地震地质效果。

The sueface seismogeologic condition in Weishanhu Lake area is very comlicated. We used 3D seismic attribute technique in the area,improved the coupling effect of radiodetector, and got high SNR 3D seismic data. Explaned the data with 3D visualization, correlative data system and seismic attribute technique, the method improved the ability to identify small underground geological strcture and seismic anomaly body. It perfected the the 3D seismic prospecting technique,and enlarged its applied range, and provided a useful method for the tectonic and geological problem in coal mining.
