| 中文摘要:高原生态脆弱区若尔盖铀矿田是我国四大基本类型铀矿田之一，地处高原藏区、生态脆弱、山高坡陡，地层为灰岩、硅灰岩及碳质板岩交互，区内断裂构造发育，岩层产状陡，孔内漏失、垮塌、水敏缩径及孔斜并存，导致取心率低、钻进效率低、质量差。解决若尔盖钻探技术难题是一项系统工程，从改善孔内安全、提高钻进效率、改善施工质量、减少钻机搬迁及提高搬迁效率等方面集成创新、综合治理，形成一套适合若尔盖复杂地层的综合钻探技术体系，在西部高原及深孔复杂地层钻进具有示范与推广作用。 |

| Abstract:Ruoergai uranium deposit is one of the four basic types of uranium ore field in China, where the limestone, silicon limestone and carbonaceous slate are interbedded. The development of faults and steep rock occurrence in this area are the main reasons for hole leakage, collapse, shrinkage and deviation, which also lead to low coring rate, low drilling efficiency and low drilling quality. To solve these drilling problems in Ruoergai is a system engineering, the integrated innovation and management should be started from improving hole safety, drilling efficiency, construction quality, reducing rig moving times and improving removal efficiency to form a set of comprehensive drilling technology system suitable for the complex strata in Ruoergai. This drilling system has demonstration effects for drilling in Western Plateau and deep hole of complex formations. |
