摘要
分析了地应力钻孔测量过程中对金刚石钻头所提出的特殊要求 ,阐述了钻头设计思想。并且针对云南小湾电站、糯扎渡电站坝址区的岩石性质以及所研制的用于地应力钻测的金刚石钻头试验结果进行了讨论分析。
In the paper espections of the diamond bits which aer used in drilling measure of formation stress are analyxed and the design thought of new bits are shown.The character of rock at trial area the test results of new bits are diacussed.
