本文概述了趋势分析对地震构造图的解释功能.针对剩余构造对油气聚集的控制作用,提出了剩余趋势图的解释方法.研究结果表明,趋势分析在石油勘探中是一种有效的方法.趋势分析是地质数据统计分析中一个重要的常用方法.其基本功能是将一组空间分布的地质数据分解成两部分:一部分反映地质变量在区域范围内的变化特征,另一部分则反映地质变量在局部范围内的变化特征.针对本题来说,也就是将某一地区的地震构造图,分解成反映区域变化的趋势面图和反映局部变化的剩余趋势图;从而使地质变量
In this paper, the interpretation function of trend tectonics on seismic tectonics is summarized.Aiming at the control effect of residual tectonics on hydrocarbon accumulation, a method of interpretation of the residual trend graph is proposed.The results show that trend analysis is an effective method in petroleum exploration. Analysis is an important and commonly used method in the statistical analysis of geological data, and its basic function is to decompose a set of spatial data into two parts: one part reflects the change characteristics of geological variables in the region, and the other part reflects that geological variables are locally Within the scope of the change characteristics.For this problem, that is, the seismic structure of a region is decomposed into a reflection of the trend of the regional changes and the trend of the residual trend of local changes; so that the geological variables
