This paper introduces the construction of a 200.35m deep, 2m diameter, ≤0.5‰ downslope using composite drilling method. In this method, the pilot hole and reaming are constructed with the BMC-D90 directional drilling rig and BMC400 reverse well rig independently developed by Beijing Zhongmei, respectively. During the construction, a wireless while-drilling inclinometer is used to monitor the drilling trajectory of the wellb. The downslope well project was successfully completed under the premise of ensuring construction quality. The successful completion of this project helps to promote the overall project and also provides a reference for implementation of similar projects in the future.
