Abstract: 1 000 m drilling technology can realize the directional drilling of long boreholes and the accurate control of the borehole trajectory, and can also improve the gas drainage efficiency, but there are lots of problems in its actual application. This paper summarized the application status and existing problems of 1 000 m directional drilling technology, it pointed out that the research of the applicability of 1 000 m directional drilling technology, the rationality of its drilling parameters and drainage parameters matching and its safety and economic benefits should be strengthened so as to fully and effectively play its technical advantages.
