复杂构造建模技术在地震反演中的应用
|
摘要
随着勘探的不断深入,面临的地质条件越来越复杂,储层预测难度越来越大。针对复杂构造勘探目标,详细阐述了复杂构造建模原理及其对地震反演的影响,探讨了复杂构造背景下构造建模约束的初始反演模型与常规初始反演模型的区别和优势;利用GeoEast一体化平台复杂构造建模及属性建模解决了复杂构造情况下初始反演模型如何建立的难题,特别是逆掩断层上、下盘附近的模型细节问题,为地震反演提供了精度高、符合地质认识的初始反演模型。
In the present exploration,geological conditions are becoming more and more complicated,and it is much more difficult to do reservoir prediction.Aiming at complex-structure targets,this paper discusses in detail the basic principle of complex structure modeling and its influence on seismic inversion,the difference and advantage between the initial inversion model with constraints of structural modeling and the conventional inversion model under complex structure background.Using GeoEast integrated platform for complex structure modeling and attribute modeling,we solves the problem of the initial inversion model building in complex structure,especially model details near the upper and lower walls of overthrust faults are clearly built up.Our application proves that tools provided by GeoEast can build high-precision initial inversion models for seismic inversion.
