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 the test results of core physical parameters with the physical parameters obtained from interpretation of well logs, it shows that there is a good linear relationship between them. The core velocities obtained by the laboratory and the velocities obtained by acoustic logging are in good agreement with the well depth. The Young’s modulus is found to be approximately elliptical and has obvious anisotropy. The result of this tentative study is extremely convenient for determining physical parameters in the field and provides material for the interpretation of well logging data. It also provides a convenient method for obtaining physical parameters for the exploration and development of coal fields. It can be seen from the results of this comparative analysis that there is a good prospect of application in coalfield exploration.
