摘要
According to the features of bauxite formation, the analysis was made on the drilling technology. By the theoretical discussion on conventional wire-line coring drilling, general dual-tube drilling and swivel type dual-tube drilling with PDC reinforced bit and by the comparison of field tests, the causes of sticking failure with conventional drilling methods in bauxite formation and low drilling efficiency were found. It was proved that the sticking failure could be solved by swivel type dual-tube drilling with PDC reinforced bit and the drilling efficiency was improved.
