Operating Guidelines and Precautions for Wellhead Tools and Drilling Equipment

Hydraulic vise

Main structure

Q10Y-M hydraulic vise consists of key components such as travel gearbox, deceleration device, clamp head, air control system and hydraulic system.

Main technical performance

The hydraulic system of this hydraulic vise has a rated flow rate of 114 liters per minute and a maximum working pressure of 16.3 MPa, and is equipped with a 40 kW electric drive motor. The working pressure of the pneumatic system ranges from 0.5 to 1.0 MPa, which meets different operational requirements.

Operating Precautions

When using the hydraulic tongs, make sure that the size of the tong head pallet matches the size of the drill pipe joint. During the process of moving the large pliers to the wellhead, the air valve should be avoided to close to the bottom at one time, in order to prevent the rapid movement of the pliers from causing impact. In addition, it is prohibited to lift the drilling tool until the male clasp has been fully rotated out of the female clasp and the large jaws have been loosened from the drilling tool. When deactivating the vise, it is necessary to restore all liquid and gas valves to the zero position, close the vise gas line valve, and follow the operating mnemonic of the up and down buckles for proper operation.

Drilling equipment is the core of drilling operation, which covers several key parts such as hoisting system, rotating system and circulation system. Among them, the hoisting system is especially critical, which is responsible for lifting and lowering drilling tools, casing and other important tasks, while the winch is the core component of the system. The winch is the core component of the system. The winch not only provides the required lifting speed and lifting quality for drilling, but also controls the drilling pressure and feeds the drill pipe and drill bit during the rotary process. In addition, the winch can also be used for loading and unloading drilling tools, lifting pipes and weights, as well as serving as a variable speed and intermediate transmission mechanism for the rotary table. Its structure is complex but powerful, which provides a strong guarantee for the efficient and safe drilling operation.
