Based on the engineering difficulties in directional drilling regional control, such as insufficient casing weight in the straight hole section caused by the length of the making inclination section longer than the vertical depth of the borehole, large friction resistance between the casing and the hole wall in the making inclination section, and easy to cause the casing to be stuck and unable to reach the position, a new pipe lowering process composed of floating shoes, floating hoops and roller centralizers was proposed. Floating shoes were installed at the bottom of the casing, and floating hoops were set at the 35° ~ 40° position of the making inclination section. The annulus between the floating shoes and the floating hoops was suspended without grouting to reduce the friction resistance, and the mud was poured into the upper part of the floating hoop to increase the counterweight. The roller centralizer was arranged in sections of the making inclination section to convert the sliding friction into rolling friction and realize the drag reduction of the casing in the middle. The engineering example showed that the process was simple in structure, convenient in operation and did not extend the construction period. It could effectively solve the problem of difficult casing lowering in super-long making inclination section, and the construction was safe and reliable. It could provide technical reference for the construction of water plugging directional hole in deep coal mine area.
