地层(体)切片技术及其应用
|
摘要
地层(体)切片技术自提出后就得到了广泛的应用,不只是在地震沉积学上的应用,很多时候也应用于储层的预测方面,已成为目前全三维地震综合解释的常用手段,同时在应用过程中也出现了新的变化。将地震属性切片分为时间切片、沿层切片、地层切片和地层体切片,着重对地层切片和地层体切片进行了严格区分与详述。在对地层切片技术原理及应用条件分析基础上,结合其在大港油田滨海斜坡区的应用,指出应用地层切片技术时应注意其所适用的地震、地质条件,描述了参考等时面的提取方法及使用技巧等,为地层切片技术的应用提供借鉴。
Stratal(body) slice technology has been widely used since it is proposed,which is used not only in seismic sedimentology but more often in reservoir prediction.At present,this technology is a common means in the full comprehensive three-dimensional seismic interpretation,meanwhile it has some new changes during applications.Seismic attributes slice are divided into time slice,horizon slice,stratal slice and stratal body slice in this article.Stratal slice and stratal body slice are distinguished in detail in this paper.Based on analysis of the principles of stratal slice technology and its application conditions,combined with the application in Binhai slope of Dagang oilfield,this paper indicates that we should pay attention to applicable seismic and geological conditions when using this technology,and describes the extraction of isochronous surface and the application skills.These can provide references for the applications of stratal slice technology.
