Abstract: This paper introduces the sliding directional drilling and the key of sliding rotary compound drilling technology based on VLD-1000 directional drilling rig. Using compound drilling, we successfully drilled a series of super long drilling holes over 1, 746 m, 6 of which are over 2 000 m long drilling holes. The combined drilling greatly improves the directional drilling technology, which has enriched the plan countermeasures for the gas pre-pumping in the wells, and increased the freedom of the overall planning of extraction, tunneling and recovery. It is of great significance to apply compound directional long drilling rig technology for gas treatment in coal mine and even special areas.
