岩芯声学特性与原位测井参数对比研究

通过实验室对岩芯物性参数的测试结果与由原位声波测井曲线获得的物性参数进行的对比研究，得出它们之间呈良好的线性关系。利用纵波速度与波速比的关系可以区分岩性，同时还得出剪切模量与孔隙度成反比关系。这一研究结果给实地确定岩层物性参数带来了极大的方便，为油田、煤田勘探开采提供获取力学参数的简便方法，将为测井和地震勘探资料解释提供实验基础。

Comparative Research of the Acoustic Characters of Rock Core Samples with the Graph of Well-Logging in Site

By comparing physical parameters of rock core samples with those derived from the interpretion of the graph of well-logging, the paper obtains the approximate linear relationship between them.Sandstone and limestons can be marked off through the relationship between V, and V,/V.' The paper also shows that shear modulus is in inverse proportion to porosity. These results make it covement to determine physical parameters by on-the-spot investigation, and they provide a simple method for obtaining mechanical parameters in oil and coal mine exploration, they also provide the experimental basis for data explaining of well-logging and seismic prospecting.
