摘　　要：通过对岩芯物性参数的测试结果与由测井曲线解释获取的物性参数的对比研究，表明它们之间具有良好的线性关系。实验室获得的岩芯波速与声测井获取的波速随井深变化的趋势非常一致，并发现杨氏模量呈近似椭圆规律变化，具有明显的各向异性。这一尝试性研究结果，给实地确定物性参数带来极大的方便，给测井资料的解释提供了素材；为煤田的勘探、开发提供了获取物性参数的简便方法。从这一对比分析结果可以看出，在煤田勘探方面有较好的应用前景。By comparing test data of physical parameters of cores with those derived from the interpretation of the diagram of well logging, the authors found a tendency that the wave velocity changes with the well depth measured from core tests coincides with that obtained from acoustic logging. It is also found that the Young's modulus nearly changes in a pattern of ellipse, showing obivious anisotropy. The results of the research provide great convenience in determining the physical parameters on the site, and it also offers a simple method to get the physical parameters in prospecting and exploitation of coalfields. From this we can see that this method is very promising in prospection of coalfield.
