drill Pipe

 

What is Drill Pipe?

Drill pipe, is hollow, thin-walled, steel or aluminium alloy piping that is used on drilling rigs. It is hollow to allow drilling fluid to be pumped down the hole through the bit and back up the annulus. It comes in a variety of sizes, strengths, and wall thicknesses, but is typically 27 to 32 feet in length (Range 2). Longer lengths, up to 45 feet, exist (Range 3).

 

How to Work with Drilling Pipe?

The drilling tool is connected drill rod for transferring power. The drill string is usually part are: drill, drill collars, drilling pipe, stabilizers, special connectors and Kelly. The basic role of the drill string are: (1)control the drill bit; (2) imposed WOB; (3) transmission of power; (4) transporting drilling fluid; (5) special operations: extrusion of cement, handling underground accidents.

 

Drilling pipe is trailing with screw thread for connecting the drilling rig located at the bottom of surface drilling equipment and mill equipment or bottom outlet device. The purpose is to drill the drilling mud delivered to the drill bit, and drill with the increase, decrease or rotating bottom outlet means. Drill pipes must be able to withstand great external pressure, twisting, bending and vibration. In the mining and oil and gas refining process, the drill pipe can be used multiple times.

 

drill Pipe: Drill pipe ay nagsasama ng pipe katawan at tool joints (kahon at pin) welded magkasama, na ginagamit upang kumonekta pagbabarena magsangkap ibabaw kagamitan at ibaba kagamitan o ibaba hole kagamitan. Drill pipe ay maaaring pasanin mabigat na panloob at panlabas na presyon, at iba ng kahulugan, yumuko at panginginig ng boses na pwedeng gamitin ng higit sa isang oras sa panahon ng langis o gas produksyon.

Drill pipe ay steel tube nilagyan na may sinulid dulo na tinatawag na tool joints, na kung saan ay karaniwang ginagamit sa pag-igting sa tuktok na bahagi ng drill string upang mag-usisa tuluy-tuloy at ipadalang-kawad metalikang kuwintas sa bit.
