| 中文摘要:在鄂西地区磷矿、铅锌矿、银钒矿赋矿地层及上覆地层中，普遍存在着坚硬岩层。震旦系白云岩中含大量的硅质层和经化学沉积形成的“玉髓”层，硅质含量超过80%，并且结构致密，呈弱研磨性，岩石可钻性达到Ⅸ～Ⅹ级。通过钻探现场生产试验，从金刚石钻头选型、人工修磨钻头方法、金刚石钻进工艺参数选择等几个方面总结了生产实践中取得的成功经验，为今后进一步解决钻进打滑问题提出了思路。 |

| Abstract:In host strata of phosphate rock, lead-zinc mine, silver and vanadium ore and overlying strata of western Hubei, there is common existence of hard rocks. Sinian dolomite contains a large amount of silicon horizon and “chalcedony” layer formed by chemical vapor deposition, silicon content is more than 80% with dense structure, low abrasiveness and drillability of Ⅸ～Ⅹ level. By the test in drilling field, the paper described the diamond bit selection, artificial bit conditioning and diamond drilling process parameters selection; summed up the successful experience in construction practice for further resolving drilling slipping difficulty. |
