地震属性优选在油田开发中的应用
|
摘要
在应用地震属性进行储层预测时,如何从众多地震属性中优选出适用于本区特征的地震属性是关键。特别是在油田开发阶段,优选储层的地震属性更加重要。本文提出以地质、测井和岩石物理资料为基础,利用数学模型和正演模拟进行属性优选,再用留一交替法选出适于工区地质情况的最佳属性组合。这套方法充分利用工区内已有资料,发挥地质、测井及岩石物理方法的各自优势,减少了属性优选的多解性,提高了储层预测的准确性。该方法简便实用,可操作性强。
By using seismic attributes for the prediction of reservoirs, the key is how to optimize seismic atrbutes adaptable to the feature in the region from multiple seismic attributes. Especially in development stage of oilfields, optimization of seismic attributes of reservoirs is more important. The paper presented an optimization of seismic attributes that takes geologic, logging and petrophysical data as a basis, uses mathematic model and forward simulation to optimize the attributes and then selects the combination of optimum attributes suitable for the geologic situation in that area by using alternative method remaining the best one. This set of methods fully utilized available data in the work area, gave a full play to respective superiority of geologic, logging and petrophysic methods, reduced multi-solution of optimized attributes and improved accuracy of prediction of reservoirs. The method is practical and easy to use with better maneuverability.
