Titanium alloy drill pipe
Product details

Titanium alloy drill pipe is light weight drill pipe, which can effectively reduce the friction and torque of drilling tools in horizontal wells,Thus, the horizontal offset and the length of horizontal section can be extended effectively and substantially, and the stress corrosion fatigue strength is more than 10 times higher than that of carbon steel now in use. Therefore, the damage tolerance and service life of drill string can be greatly increased.Due to its high mechanical strength, good flexibility, excellent corrosion resistance and low specific gravity, titanium alloy drill pipes can be used not only in conventional wells, but also in ultra-short radius wells, ultra-large displacement wells and other difficult drilling conditions.In addition, the lightweight drill string composed of titanium alloy drill pipes can reduce the large hook load, reduce the torque and friction, and further improve the mechanical drilling speed.At the same time, the non-magnetic property of titanium alloy also provides convenience for the normal use of some equipment.
 


 

Feature
 
● High corrosion resistance
 When the ambient temperature is below 330 ℃, titanium alloy drill pipe can resist the corrosion of H2S, CO2 and Cl -.
 
● Low density
 Compared with the steel drill pipe of the same specification, the weight of the drill pipe is reduced by 43%, which can meet the drilling requirements of ultra deep wells over 10000 meters
 
● High toughness
 Compared with steel, modulus of elasticity decreases by 43%. It can be applied to short radius horizontal wells with curvature radius less than 30 m. It can meet the requirement of ultra short radius horizontal wells with curvature radius of minimum 18 M.
 
●  Non-magnetic
 No effect on logging operation.
 
● Long fatigue life
 The fatigue life of steel drill pipe is 10 times in air environment and 100 times in corrosive environment.
