几种地震波阻抗反演方法的比较分析与综合应用
|
摘要
地震波阻抗反演是确保地震数据、测井资料和地质信息正确综合的重要技术。对当前石油工业界常用的地震波阻抗反演方法的原理、技术关键、优缺点及应用条件做了较为详细的分析和评述,并展示了几种反演方法综合应用的实例。实例表明,遵照拟定的技术流程,能够在实际生产中较好地使用各种反演方法,并得到较为可靠的一体化综合储层预测结果,可以降低油气勘探开发的风险。
Seismic inversion is the essential first-step to ensure the proper integration of seismic data, well-logs,velocity and geological information. The authors made comparison among some seismic impedance inversion methods usually applied by oil community in principles,key ways,work flows,advantages, disadvantages and applying conditions. The seismic inversion practice indicates that good reservoir prediction results could be gained following the rules and work flows,with reduction of the E & P risk.
