Drilling through the thrust block in the well Longshen1 had encountered the problem of strong natural formation deflection tendency due to high formation dip variation. The combination of tapered assembly, pendulum assembly and largediameter PDC bit had resulted in difficult deviation control and low ROP. The composite drilling using bent sub PDM and rotary drilling had improved the ROP to some extent, but still far from the desired ROP improvement goal.
