三维地震在储层岩相随机建模中的应用
|
摘要
随着储层随机建模技术的发展,相控储层随机建模得到了广泛的应用,但是在海上油气田开发前期,测井资料较少,储层岩相建模便成了难题。通过结合测井纵向分辨率高、三维地震资料平面连续性强的特点,以三维地震属性作为平面约束,并为岩相随机建模方法提供变差函数参数,依据井震结合的思路来进行研究。最后提出了三维地震在岩相建模技术中应用流程、方法和5个关键步骤。通过在实际油田储层建模中进行应用,取得了较好的效果,为储量评价、开发方案设计和油藏数值模拟提供依据。
With the development of stochastic reservoir modeling techniques,the facies reservoir stochastic modeling has been widely used,but because less log data before the development of offshore oil and gas field,the lithofacies modeling of reservoir is very difficult.By combining the characteristics of logging data with the high resolution in vertical and 3D seismic data with the strong continuity in the plane,the 3D seismic attributes provide the plane constraints and variogram parameters for the lithofacies stochastic modeling,According to the combination idea of seismic and logging data to study.This paper advances the workflow and method and 5 key steps of 3D seismic application in the lithofacies stochastic modeling.By application in the reservoir modeling of the development oil field,the technology achieved good results that provide the basis for the reserve estimation,the design of the overall development plan and the reservoir numerical simulation.
