饱和流体多孔介质中AVA特征分析与正演

储层的岩石物理模型是以流体饱和多孔介质为基础的,而分析储层的AVA(Am p litudeversus ang le)特征可以得到与储层孔隙度和充填流体有关的重要信息,它是一种行之有效的直接寻找油气的新方法。本文在B iot理论的基础之上,设计了不同储层的理论模型,并正演计算了它们的AVA响应曲线,分析不同储层理论模型的AVA异常特征响应可获得与储层和充填流体有关的信息。正演计算的结果说明了储层的AVA响应特征,为实际应用AVA特征进行储层预测和流体识别奠定了基础。

The rock-physics model of reserviors is on the basis of Fluid-saturated Porous Media.Analys is of the AVA character of reserviors can gain many informations such as porous ration and fluid type.As a effective method,it is used to seek oil and gas mineral resource.This paper on the basis of Biot theory,calculated the different AVA response curves for different reserviors models.By analysing this curves,we can learn the difference of AVA character between the reserviors and non-reservoirs.The result of forwar...
