5. Helpful for keeping the direction of directional well.
4. Easy for the stem's handling and operation
3. Reducing the tiresome damage of tool-joint connection
2. Bring along the drill collar of stem within Less time
1. Reducing torque in high-rpm or deep drilling.
It made from AISI 4145H alloy steel and fully heat treated, all its physical properties conform to the latest API Spec 7. Heavy drill pipe is the transition section between ordinary Kelly and drill collar. It can relieve the stress concentration of the combition of drill collar and Kelly during the transition. Besides, it can provide drill pressure and reduce the linked area of drill stem and side wall, as well as wear rate of OD. There is an upset section in the middle of drill pipe. The drill pipe and joint are welded with cemented carbidehardbanding, which can effectively keep the pipe from wearing. HWDP can replace drill collar and solve series of problems appearing in the vertical well of softer geologic structure. Its advantages are as follows:
It made from AISI 4145H alloy steel and fully heat treated, all its physical properties conform to the latest API Spec 7.
