Because of geological structure development, large dip angle formation, and inter-bedded soft and hard formation at Hongliu Coalmine of Shenhua Ningxia Coal Industry Group, freezing wells were easy to deviate, and gyro and mud motors were needed to make correction drilling for a few times, delaying the project progress. To solve these problems, compound drilling was performed with combination of the PDC or cone bit and the 1° single bent motor, achieving good results in anti-deflection, and improving ROP. It may provide some reference for other similar projects.
