摘要

层序格架约束地震反演进行储层预测的核心是,应用层序地层学理论开展层位解释,建立地质模型约束反演结果,地质模型越精细,反演精度越高。本文通过常规地震地层解释、地震层序识别与反演三者相结合,应用三维工区内的层序、最大湖泛面、体系域、准层序等界面建立地质模型,在哈萨克斯坦中部南土尔盖盆地鲍金根地堑西斜坡实现了快速高效的地震反演,提高了储层预测的精度。
The key of sequence framework constrained seismic inversion for reservoir prediction is to apply sequence theory to interpret horizons,and build geologic models to constrain inversion results.The finer geologic models are,the better inversion precision is.Using the joint-research of horizon interpretation,seismic sequence identification and inversion,we apply quite few geological data such as sequence surface,maximum flood surface,system tract,subsequence surface,to build geologic models to constrain inversions.Application results show that the sequence constrained seismic inversion is improved.
