中文摘要: |
文章分析探讨铝土矿地层钻探工艺,采用常规绳索取芯钻探、普通双管钻探与PDC双管钻探对比进行,钻进中采用常规钻探方法常发生钻具粘附孔壁而产生的卡钻问题,致使钻探效率低,采用PDC钻头双管钻探不仅较好地解决了粘附孔壁而卡钻的问题,而且提高了钻探效率。 |
英文摘要: |
In the paper the authors analyzed and discussed the drilling technology in bauxite strata, through the comparation of conventional rope core drilling, normal twin pipe drilling and drilling PDC double. Conventional drilling method could not solve drill hole wall adhesion and sticking problems, often making drilling with low efficiency. While PDC bits and double pipe drilling can better solve the adhesion of the hole wall and the sticking of problems, improving drilling efficiency. |
