基于Xu-Payne模型的岩石物理模板制作

摘要

The rock physical template was established based on the theory of rock physics,it was widely used in rock physics analysis and quantitative seismic interpretation,the research results of carbonate rock physics template were few.Based on the actual data in this paper,a rock physical template of carbonate rocks was established by using the related petrophysical model,the variation of elastic parameters under different porosity,gas saturation and shale content was analyzed,finally,the rock physical relation templates between reservoir parameters and elastic parameters are established under different porosity,gas saturation and shale content.The template has certain guiding significance for quantitative evaluation of porosity,saturation and other reservoir parameters in areas with the same depositional environment and without drilling.%岩石物理模板是基于岩石物理理论建立的,在岩石物理分析以及定量地震解释中应用广泛,针对碳酸盐岩岩石物理的模板研究成果较少.基于实际数据,采用相关岩石物理理论模型建立碳酸盐岩岩石物理模板,分析了弹性参数在不同的孔隙度、含气饱和度和泥质含量情况下的变化规律;模拟了在不同的孔隙度、含气饱和度、泥质含量的情况下,建立起储层参数与弹性参数之间的岩石物理关系模板.该模板在有相同沉积环境且未钻井的区域,对定量评价孔隙度、饱和度等储层参数有一定的指导意义.
