本文以川西南隆昌地区二叠系阳新统茅口组上部含气裂缝发育带的预测为例,介绍了用人机联作解释系统对三维地震资料进行构造精细解释和振幅研究,从而预测含气裂缝发育带的方法,并通过钻井对比证实了方法的有效性.

This paper gives a description of precise structure interpretation and amplitude analysis for 3D seismic data with an interactive interpretation system taking the survey in Longchang Region of the southwest of Sichuan for predicting gas-bearing fracture-developed zones in upper Maokao Group in Yangxing Scries of the Permian as an example.The method has been confirmed to be effective with drilling data.
