地层切片技术及应用

STRATA SLICING TECHNOLOGY AND ITS APPLICATION

为了使地震属性切片更加接近于地下真实情况,且具有等时地质意义,文章从地层切片技术的概念、内涵、实现步骤入手,应用地层切片技术分析了A地区B层位的河道展布特征以及沉积演化情况,取得了较好的效果。根据地层切片的概念、内涵以及在A地区的实际应用,得到地层切片技术比传统的时间切片和沿层切片更加接近于等时界面,具有等时地质意义,能够更好的解释沉积演化现象。使地震解释地质化,是一门有价值的解释技术,将在以后的地震解释中扮演重要的角色。

In order to making seismic attribute sections closer to the real situation and geologically isochronous,this paper has analyzed the river channel distribution and sedimentation evolution of the 'B'interval at A area by slicing technology in terms of concept,connotation and application steps.Good results have been obtained.They are closer to the isochronous interface than traditional timeslice and slice along the layer.The strata slicing can better interpret sedimentary evolution.It makes seismic interpretation more geological,it is a valuable seismic interpretation technology and will play an important role in future seismic interpretation.
