CNPC Bohai Equipment "Titanium Alloy Drill Pipe" Won The National Invention Patent
Recently, China Petroleum Bohai equipment Company bohai Can gram "titanium alloy drill pipe" to obtain the national invention patent. As a leading enterprise of high-quality and high-strength drill pipe in China, Bohai Nengke Drill pipe Co., Ltd. successfully developed the world's first friction welding #titanium alloy drill pipe in 2017, making China successfully rank among the advanced countries in the development and production of high-quality titanium alloy drill pipe. All the product fittings and pipe material for titanium alloy, titanium alloy at home and abroad innovative change drill pipe tool joint and the conventional steel titanium alloy pipe tube body with cold assembly way connected into a whole pipe, through advanced mode of friction welding connection, broke the titanium alloy pipe end upset thickening, the pipe body heat treatment and body joint friction welding technology, such as problems.
The national patent "titanium alloy drill pipe" series of products have been batch off the production line and passed the industrial test, and completed the relevant drilling tasks of domestic oil and gas Wells such as CNPC and Sinopec with high quality. The drill pipe can reduce rig load by more than 40%, thus reducing rig selection specifications and reducing construction energy consumption. The life in air is 10 times longer than that of conventional drill pipe of the same specification, and 100 times longer than that of conventional drill pipe in corrosive environment, which greatly improves the safety and service life of drill tool, especially suitable for ultra-deep Wells, short radius Wells and other complex well conditions in northwest China.
