趋势面分析技术在低幅度构造油气藏识别中的应用——以鄂尔多斯盆地天环坳陷为例
|
摘要
近年来随着勘探技术的发展,作为油气勘探重要接替领域之一的低幅度构造研究得到人们越来越多的重视.但是,针对地层倾角较大的地区,以往的地震地质勘探技术不能够准确预测其构造高点和圈闭面积.因此,针对研究区地层倾角较大的情况,运用二维趋势面技术进行低幅度构造的识别.从而更准确地突出低幅度构造背景上的高低点,使低幅度构造圈闭识别精确度更高,低幅度构造刻画更加准确,形态更加合理,为研究区油气勘探提供有利目标.
In recent years,with the development of exploration technology,the study of low-amplitude structures,as one of the important succession fields of oil and gas exploration,has attracted more and more attention.However,for areas with large dip,previous seismic and geological exploration techniques can not accurately predict their high point of structure and trap areas.Therefore,in view of the large dip of strata in the study area,the two-dimensional trend surface technology is used to recognize low-amplitude structures.Thus,the high and low points in the low-amplitude structural background can be highlighted more accurately,the recognition accuracy of low-amplitude structural traps is higher,the description of low-amplitude structuresis more accurate,and the shape is more reasonable,which provides favorable targets for oil and gas exploration in the study area.
