基于全局优化地层模型的地震层位自动追踪技术及在鄂南应用效果分析

A new method to interpret large seismic data based on global optimization stratigraphic mode and its application effect in the southern of Ordos basin

在勘探和开发中,地震层位解释是一项基础工作,而层位的识别和追踪是地震层位解释的一个重要的环节。一般情况,层位追踪基本上是手工或单剖面的自动追踪,既耗时又耗力,又受制于局限的视野。本文介绍了一种基于全局优化地层模型的地震层位自动追踪技术,该技术在多尺度建模的基础上,不断修正地层模型,能够快速且精确地完成层位追踪任务。而后在鄂南实际生产过程中,结合不同品质和构造类型的地震资料,进行了一系列的应用及效果分析。

In seismic exploration and development, seismic horizons interpretation is a basic work, but seismic horizons of identification and tracking is a very important part.General,traditional seismic interpretation based on labour intensive horizons tracking,which subject to the limitations of vision.In this paper,we present a new method to interpret large seismic data sets using on a novel global approach.This method is based on global optimization,which aims to compute a geological model directly from the seismic information.Based on this,a series of application and effect analysis was applied in southern of Ordos basin production process.
