摘要：
The PowerV vertical drilling technology ("PowerV") is a deviation-control ROP enhancement technology for vertical wells in high dip structures. Essentially, it is necessary to select bits rationally and control performance indicators of drilling fluid. In this paper, the first trail application of PowerV to Well X01 in the high dip structure, western Sichuan Basin, was analyzed in terms of its structures, working principles and BHA (bottom hole assembly) requirements. In the 933-2 757 m interval of the Φ316.5 mm hole, the deviation of the borehole drilled by PowerV is less than 1.2° and the ROP (rate of penetration) is 4 times higher than that of conventional BHAs. Compared with the drilling results of the same interval in the neighboring well, PowerV doubles the ROP by virtue of higher WOB (weight on bit) and RPM (revolution per minute). Test results show that the trip time can be cut down by adopting the imported bits with better performance; that the operation time of complete solid control equipment should account for over 85% of the circulation period to ensure the satisfactory performance of drilling fluid in the well; and that the pressure resistance of the circulation system should be high enough to meet the basic pressure drop requirement of PowerV. It is concluded that PowerV can be used to control the wellbore quality in high dip structures and increase ROP significantly, thus having great spreading values and application prospects. © 2016, Natural Gas Industry Journal Agency.
