Lifting sub
The lifting nipple is a special tool for lifting drilling tools in oil, gas, and geological exploration drilling engineering. The lifting nipple is made of heat treated alloy structural steel, and its design and manufacture comply with API specifications. Lifting nipples can safely and efficiently load and unload drilling tools, such as drill collars, drill pipes, jars, and other tools.
Protective joint
When adding drill pipe to increase drilling depth, it is now loose at the lower end of the joint rather than the most valuable kelly in the drill string. This means that the protective joint and the upper threaded connection of the kelly are rarely used and have minimal wear, while the lower threaded connection is used in almost all cases, with most wear shifting from rotary head connections to cheaper protective joints, which are consumables and reduce costs.

Drift diameter gauge
The drift diameter gauge is a simple and commonly used tool for measuring the drift diameter of casing, tubing, drill pipe, and other pipes. It can be used to check whether the internal diameter of various pipes meets the standards, and to check the maximum geometric size that they can pass through after deformation,
It is an essential tool for testing workover operations.
There are two types of commonly used casing drift diameter gauges:
One form is that both upper and lower ends are machined with connecting threads, the upper end is linked to the drilling tool, and the lower end is for standby. The other form mainly consists of a drift diameter gauge plate and a connecting rod. Tubing or drill pipe drift diameter is generally conducted on the ground. The drift diameter gauge is formed as a long main body with sucker rod threads at both ends, connected to the sucker rod, and is manually calibrated.

Kelly cock valve
The kelly plug valve is a manual control valve in the drill string circulation system, and is one of the effective tools to prevent blowout. The kelly cock is divided into an upper kelly cock and a lower kelly cock. The upper kelly cock is used between the lower end of the faucet joint and the upper end of the kelly, and the lower kelly cock is used between the lower end of the kelly and the upper end of the drill pipe or the upper end of the kelly protection joint. Use a special wrench to turn 90 ° according to the instructions to achieve the switch. In drilling operations, in order to avoid the occurrence of malignant blowout accidents, kelly cocks should be assembled at the upper and lower ends of the kelly.

The full bore safety valve is a manual control valve in the drill string circulation system, and is one of the effective tools to prevent blowout and kick. The safety valve is used between the lower end of the kelly and the upper end of the kelly or at the lower end of the kelly protection joint.
In order to avoid serious blowout accidents during drilling operations, safety valves should be connected to the pipe string. The full bore safety valve is a ball valve with simple structure and convenient maintenance. It has the characteristics of full bore and large bore, greatly reducing the erosion and wear of drilling fluid on key components. The full bore safety valve adopts a split structure to ensure the larger bore requirements for the same threaded connection.

The arrow shaped check valve is also called an arrow shaped back pressure valve. It is one of the commonly used blowout tools in drilling tools for oil and gas drilling and workover. It works with the drilling tool in the well. Once overflow occurs during drilling or workover, a kick or positive circulation stops. Under the action of reverse circulation pressure in the drilling tool, the arrow shaped check valve quickly closes, cutting off the internal passage of the drilling tool, and achieving the purpose of blowout in the drilling tool.
