Based on the strong research and development platform of Hailong Petroleum Pipe Research Institute, Hailong Petroleum Drilling Tools uses internationally advanced thickening technology, heat treatment technology, friction welding technology and advanced production and testing equipment, not only providing users with all APIs. Standard specifications and steel-grade conventional drilling tools, meanwhile, through independent research and development, we provide users with various special products and high-end products to meet customers' differentiated and personalized needs.
Oil and gas exploration and production are becoming more and more difficult. Deep wells, horizontal wells, extended reach wells, sulfur-containing environments, low-temperature environments, etc., are increasingly demanding drill pipe performance, and API standard drill pipes are becoming increasingly difficult. To meet the requirements, for this reason, Hilong has developed high-strength drill pipes (heavy drill pipes), sulfur-resistant drill pipes (heavy drill pipes), low-temperature drill pipes, and high-efficiency bed debris removal drill pipes for removing debris from inclined and horizontal wells , As well as deep-water landing drill pipes that meet the high performance requirements of offshore drilling, and a series of special drill pipes. Among them, the Hilong double shoulder special high-torsion special buckle series (HLDS, HLIDS, HLMT, HLST) provides higher mechanical performance and convenience for drilling operations for drill pipe connection.
