Selection of automatic vertical drilling system for the fourth section in Shunbei 11 well, Tarim basin, China

Based on the introduction of working principles various automatic vertical drilling systems (VDS), latter are divided into rotary push type and sliding type. Then technical advantages applicable scope types tools analysed. Combined with latest domestic application progress typical case analysis system, future development direction technology is predicted. The results show that, existing can better meet needs rapid in middle-deep sections high steep angles. While stability wireless information transmission wear resistance pad still need further improvement. new system that miniaturized (suitable for small boreholes) resistant to temperature pressure urgent fill gaps market segment. Domestic independent have made great progress, some even surpass foreign products key indicators such as resistance, addition achieving goal anti-inclination successfully. Finally, based engineering geological conditions Shunbei 11 well, feasible were recommended achieved finally. research provide support company optimize engineering-geological conditions.
