基于坡度属性的生物礁边界精细预测方法——以四川盆地罗顶寨地区二叠系长兴组为例
Fine prediction of reef boundary based on slope attributes: A case study of Permian Changxing Formation in Luodingzhai area, Sichuan Basin, SW China
摘要
Abstract
Based on the slope theory in geomorphology,a method,which can identify the boundary of platform reef by high precision slope attribute calculation based on the horizon data of fme seismic interpretation,combining the ancient geomorphic analysis method,was established.The conventional seismic prediction methods,drilling results and the thickness data of Changxing Formation were used to verify and supplement this method.Then,this method was used to identify the boundary of uplifted reef on the planar image in the Permian Changxing Formation in Luodingzhai area of Sichuan Basin.The results show that the reef boundary imaged by this method is consistent with the reef distribution revealed by the drilling,and is clearer in local details.Compared with conventional seismic prediction methods,the reef boundary identified based on the same fme seismic horizon interpretation results by this method has no multiple solution on the planar image.关键词
