Paip dril

 

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.

 

Paip dril: paip gerudi termasuk badan paip dan sendi alat (kotak dan pin) dikimpal bersama-sama, yang digunakan untuk menyambung peralatan permukaan pelantar penggerudian dan peralatan bahagian bawah atau peralatan dasar lubang. Paip gerudi boleh menanggung tekanan yang berat dalaman dan luaran, dan twist, bengkok dan getaran yang boleh digunakan lebih daripada satu masa semasa pengeluaran minyak atau gas.

paip gerudi adalah tiub keluli dipasang dengan hujung yang panjang dipanggil sendi alat, yang biasa digunakan dalam ketegangan di bahagian atas rentetan gerudi untuk mengepam cecair dan menghantar tork untuk bit.
