引言金刚石钻进是矿床评价过程中的一个主要阶段.虽然它是验证深部矿床量便宜的方法,但费用仍很大.所以,要精心设计,以最少投资取得最佳效果.好的钻孔设计,意味着对地质情况及其对金刚石钻孔偏斜的影响都有正确的认识.解决偏斜问题的途径有三种,休斯在1965年已做了概述.这三种途径是: 1.估计可能出现的偏斜量,并据此设计钻孔. 2.采用不同钻进技术使钻孔偏斜量最小. 3.如有必要,采用造斜方法矫正钻孔的方向.
INTRODUCTION Diamond drilling is a major stage in the evaluation of a deposit and although it is a cheaper way of verifying the depth of a deep deposit, it is still costly, so be careful to design it for best results with minimal investment. , Meaning that there is a correct understanding of the geology and its impact on the diamond borehole deviations There are three ways to deal with the skew problem Hughes has outlined in 1965. The three ways are: The amount of skew that may occur, and design the borehole accordingly 2. Use different drilling techniques to minimize the amount of deflection in the borehole 3. Correct the direction of the borehole, if necessary, by using the bevel method.
