Drilling slips are essential tools in oil and gas drilling and workover operations. They are used to grip and secure tubulars like drill pipes, tubing, and casings at the wellhead.

Main Functions

• Fixing Tubulars：During tripping, making connections, or other wellhead operations, they bite the outer wall of tubulars to fix them on the rotary table or wellhead device.

• Sharing Loads：Bear the weight of tubulars, reducing the load on tools such as elevators and tongs.

• Ensuring Safety：Prevent accidental slipping of tubulars and avoid wellhead accidents.

Common Types

• Manual Slips：Operated by hand levers. Simple in structure, suitable for light - duty or low - load operations.

• Hydraulic Slips：Driven by hydraulic systems. They offer high automation and large gripping force, ideal for high - pressure and deep - well operations.

Proper selection based on working conditions and strict adherence to operation standards can enhance the safety and efficiency of drilling and workover operations.
