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: bor pipa termasuk tubuh pipa dan sendi alat (kotak dan pin) dilas bersama-sama, digunakan untuk menghubungkan peralatan permukaan pengeboran rig dan peralatan bawah atau peralatan lubang bawah. Pipa bor dapat menanggung tekanan berat internal dan eksternal, dan twist, tikungan dan getaran yang dapat digunakan lebih dari satu kali selama produksi minyak atau gas.

Bor pipa adalah tabung baja dilengkapi dengan ujung berulir disebut alat sendi, yang umum digunakan dalam ketegangan di bagian atas bor untuk memompa cairan dan mengirimkan torsi ke bit.
