摘要
地震反演资料分辨率低,识别薄层精度差。本文根据地质、测井资料,以波阻抗反演资料为约束条件,应用序贯指示模拟方法建立了薄互层储层模型。结果表明,在薄互层储层建模中合理应用测井、地震资料能够发挥地质统计学优势,综合井资料的纵向高精度信息和地震资料的横向信息,提高了储层模型的纵向分辨能力,建立的模型能够解决开发阶段的薄互层储层精细描述问题。
Seismic inversion can not accurately identify thin layer because of low resolution.In this paper,according to the geological and logging,the wave impedance inversion data is used as the constraint conditions with sequential indicator simulation method to establish the thin interbed reservoir model.The reasonable application of well logging and seismic data can show the advantage of geostatistics,apply the comprehensive data of well and seismic,and improve the vertical resolution of reservoir model.This model can solve the problem of thin interbedded reservoir fine description in the oilfield development stage.
