From the reality of the Yong 42 block,through the optimization of the PDC bits and the screw drilling tools in the third open section of directional wells,at the same time,the author optimized the drilling parameters,the bottom hole assembly and the system of drilling fluid,which improved the average ROP greatly.This technology becomes one of the effective ways to improve the drilling speed in this block.
