利用地球物理测井数据计算新疆托克逊县白嘴山地区岩石力学参数的方法探讨

Discussion on the Calculation of Mechanical Parameters of Rocks With Geophysical Logging Data in Baizuishan Region,Tuokexun,Xinjiang

根据声波测井和密度测井数据可连续计算自然状态下岩石力学参数———地层岩石孔隙度、强度指数、剪切模量、杨氏模量、体弹模量、泊松比等,为工作区岩石力学特性的研究提供了可靠的依据。该方法可节约昂贵的弹性力学参数测试费用,具有明显的经济意义和实用价值。

Acoustic logging data in mine exploitation is one of the most essential data. According to ob- tained acoustic logging and density logging data, mechanical parameters of rock can be calculated contin- uously under the natural state, including porosity, strength index, shear modulus, Young＇s modulus, bulk modulus, Poisson＇s ratio which can provide the reliable basis for the study of rock mechanical char- acteristics in working area. This method can save cost of the expensive elastic mechanics parameter test, therefore have obvious economic significance and practical value.
