基于正演模型的砂泥薄互层地震属性特征分析

摘要

根据地震属性进行储层预测的研究，对于寻找油气具有十分重要的意义，但对于目前勘探中广泛存在的薄互层储层，由于受组合结构、厚度、含油气性等变化的影响，地震属性变化复杂。通过正演模拟，分析不同组合类型薄互层属性特征与储层厚度、结构、流体变化的关系，总结储层参数变化对地震属性影响程度大小，为薄互层储层地震属性预测提供了依据。%The research of reservoir prediction is very important for seeking for petroleum and gas based on the seismic attribute. But for the largely existing thin interbedded reservoir in real exploration, due to the variations of lithological combinations,thick⁃ness and fluids, complex seismic attribute changes. This paper analyzed the relationship between seismic attributes and composite structure change, fluid change, thickness parameters of the thin interbedded layers based on forward modeling, and then summa⁃rized the changes of various parameters on seismic attributes and influence degree. The results provide basis for recognizing thin in⁃terbedded reservoirs by seismic attributes.
