Drilling Line
A drilling line is a critical component in the drilling operations of the oil and gas industry. It is a strong, flexible steel wire rope used in rotary drilling rigs to support and control the movement of the drill string and other equipment within the wellbore.
HI-SEA Marine supply Drill Lines in all sizes with mill certificates and API 9A Certificate. Ropes can be terminated plain or with fittings such as open/closed Spelter Sockets.
Overview
Materials:
Drilling lines are made of high-strength steel wire to withstand the significant stresses and loads encountered during drilling operations. They are designed to be durable and resistant to wear and corrosion.
Typical construction:
6x19+IWRC, 6x26WS+IWRC, 6x19S+IWRC or 6x26WS+IWRC, etc.
Function:
The primary function of the drilling line is to hoist and lower the drill string, casing, and other downhole tools into and out of the wellbore. It is an integral part of the hoisting system of a drilling rig.
Spooling:
The Drill Line is extremely strong and generally at least 300m long. The drilling line is spooled onto a drum in the draw works, which controls the hoisting and lowering operations. As the line is used, it experiences wear and tear, so a practice called "cut and slip" is employed to move the worn sections out of service and bring less-worn sections into use.
