基于模型反演及其在STRATA软件中的应用
|
摘要
基于模型反演技术,是在精确层位标定、层序划分及储层精细对比的基础上,用地质统计技术建立储层格架模型,并利用测井资料垂向分辨率高和地震资料横向分辨率高的特点,对反映储层变化的波阻抗参数进行求取,以研究储层的分布及其变化细节。加拿大Hampson-Russellg公司研制的STRATA反演软件为一套交互2D/3D模型和反演软件,其功能是将叠后的地震道转换成波阻抗地震道,是目前广泛使用的一套地震数据反演软件。它提供了基于模型反演、宽带约束反演和稀疏脉冲反演等波阻抗反演方法。本文介绍了基于模型反演在STRATA反演软件中的实现。
Seismic inversion is playing an increasingly important role in reservoir charaeterization.On the basis of accurate horizone calibration,sequence classification,and fine reservoir correlation,a reservoir frame model was established by geostatisties.Reservoir parameters were calculated on logging and seismic data.STRATA which is usde populerly is made by Hampson-Russellg Company.It in cludes model based inversion,band limited inversion,sparse spike inversion.
