ドリルパイプ

 

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.

 

ドリルパイプ：ドリルパイプは、パイプ本体とツールジョイント（ボックス及びピン）を含む掘削リグの地表装置及びボトム装置またはボトムホール機器を接続するために使用される、一緒に溶接されます。 ドリルパイプは、油又はガスの生産中に複数回使用することができ、重内部と外部の圧力、及びねじれ、屈曲振動に耐えることができます。

ドリルパイプは、一般的に流体ポンプ及びビットにトルクを伝達するようにドリルストリングの上部の張力で使用されるツールジョイントと呼ばれるねじ端部を取り付けた鋼管です。
