Xinjiang Baiyanghe mining area is the first case of CBM development and utilization demonstration project in Fukang of Xinjiang, mountains and hills there make complicated topography with geological characteristics of high strata dip, multiple and large thickness of coal seams. Therefore, cluster wells are mainly planned in this area and the directional drilling technology is widely applied. This paper mainly analyzes the influence of well bore quality on the eccentric abrasion of tube and rod based on the drainage and production situation of existing wells in the demonstration project, and studies the directional drilling technology in this area in bottom-hole assembly and directional drilling technique optimization. Some problems in the application of directional drilling technology are discussed, which can provide technical basis for the future application of this technology in this area.
