To the technical difficulties of slow ROP and low drilling efficiency in Silurian formation of Yumen Oilfield. After investigating on the ROP improvement technologies of domestic and abroad similar formation's characteristics, proposing a drilling test program of torsion and percussion in Silurian formation of Well Yashen 1. The test well section is 3753.00~4108.05m, the accumulative footage of TorkBuster is 355.05m, the actually drilling time is 208.35h, the average ROP is 1.70m/h. Compared with the offset well, the average ROP is up to 110%.The test results are shown that: TorkBuster eliminates the "stick-slip" phenomenon effectively when the bit cutting the formation, ensures the PDC bit continue to cut the formation effectively, cuts down the drilling cycle and saves the drilling cost. It provides a new guiding ideology to increase ROP in Cretaceous formation of Yumen Oilfield.
