摘要
基于Gassmann方程.本文研究了岩性和孔隙流体性质对弹性模量的影响,由此形成体积弹性模量和剪切弹性模量的交会图,以该交会图识别岩性和流体性质.文中还提出识别流体性质的特定参数法,即从弹性模量中提取与流体性质密切相关的参数.最后,对这二种方法分别给出相应的分析实例。
Based upon Gassmann equations this paper discusses the contribution oflithological characteristics and the type of pore fluid to elastic moduli. A cross plot of bulk elastic modulus versus shear clastic modulus is thus plotted to identify the lithological charactcrisrics as well as the type of pore fluid. Besides, a so-called 'specific parameter mcthod'for identifying fluid types is proposed in the paper which implies that a number of parameters which arc closely related to the fluid' s property arc required to be extracted. Examples regarding the application of the two methods arc provided in the end of the paper.
