Universal Bottom Hole Orientation Sub (UBHO Sub) Pin and box 6 5/8" REG
Technical parameters:
The Universal Bottom Hole Orientation Sub (UBHO Sub) downhole tools is made of non-magnetic drilling tool specific stainless steel P530 or P550 which has good low magnetic permeability,high-strength mechanical properties,and excellent resistance to intergranular corrosion cracking.The drilling tools oriented sub use higher grade imported P550/15-15HS Max) for better corrosion resistance.The production process strictly follows the API Spec 7-1 specification and SY/T 5144 standard, and can also comply with the DS-1 specification.
The function of directional Universal Bottom Hole Orientation Sub (UBHO Sub):The main function is to provide a stable sealing environment for directional instruments (gyroscopes, etc.), making it easy to accurately determine the direction of downhole tools such as motors, and ensuring the smooth progress of lower operations.
The directional Bent Sub Orientation is the main tool for power drilling tools to create inclines. The angle α between the centerline of the lower thread of the directional bore hole orientation and the axis of the drill string is fixed. Under the action of the universal bottom hole orientation,the power drilling tool continuously applies lateral force to the drill bit, causing the drill bit to continuously cut the wellbore wall laterally and drill a curved wellbore trajectory.
