How to improve the service life of the top drive plug in top drilling engineering?

The top drive plug is composed of a plug body, a reaction ring, a pneumatic cylinder, etc. The plug body is the core part of the top drive plug, which is usually made of high-strength steel and has good sealing and compressive properties. It can be used normally in complex environments such as high pressure, high temperature, and high impurity content. The reaction ring is the supporting structure of the top drive plug, and its material and size should match the plug body to ensure that the plug body can work stably and reliably during operation. The pneumatic cylinder is a key component for controlling the opening and closing of the top drive plug, and its selection should mainly consider the characteristics of corrosion resistance, wear resistance, and high precision.

Top drive plug is a type of drilling tool used to control wellhead pressure and prevent wellbore leakage. It mainly consists of a rotating head and a piston. The rotary head is connected to the drill bit through the drill string, and the rotary drill bit completes the drilling operation. The piston can move the drill string up and down, adjust the distance between the drill bit and the bottom of the well, and control the wellhead pressure and adjust the drilling direction. The top drive plug can also connect the drill string and drilling fluid to control the drilling flow and prevent well leakage.

How to improve the service life of Xinjiang top drive plug in top drilling engineering?

1. Proper use and maintenance of the top drive plug valve

To use and maintain the top drive plug correctly. Before using the top drive plug, it is necessary to check the relevant parameters of the plug. In daily use, regular maintenance and inspection of the plug are also necessary to promptly detect and repair any surface or internal issues with the plug. This can keep the top drive plug in good working condition and extend its service life.

2. Reasonable use of drill rods and bits

Secondly, the selection and use of drill rods and bits will also have a significant impact on the service life of top drive plugs. It is necessary to select suitable drill rods and drill bits according to different geological environments and process requirements, and avoid using drill rods and drill bits that do not meet the requirements, in order to reduce the stress and wear of the top drive plug and extend its service life.

3. Choose appropriate lubricating oil and working environment

It is also necessary to choose appropriate lubricating oil and working environment. The correct lubricant can provide sufficient protection during difficult drilling operations and extend the service life of top drive plugs. In addition, the choice of work environment also needs to be reasonable. Proper selection of drilling fluid, equipment protection and other strategies to reduce the workload of top drive plugs and minimize wear and tear.

In practical applications, top drive plugs have brought many advantages to oilfield development and production. It can improve the production efficiency of oil wells and reduce production costs; Secondly, it can reduce the impact of bottomhole pressure on the drill pipe and tubing string, extending the service life of the drill pipe; It can prevent safety accidents such as wellhead blockage and drill string jamming, ensuring the safety of workers. Therefore, in modern oilfield engineering, top drive plugs have become an indispensable and important tool.

When using a top drive plug for wellhead sealing, it is necessary to choose the appropriate operating method according to the specific situation. In general, mud can be pressed into the wellhead through pressure foam pump, drill string, top drive and other equipment to finally open and close the top drive cock and achieve the purpose of wellhead plugging. In the actual operation process, it is necessary to pay attention to some key issues, such as preventing mud dripping, checking whether the pneumatic cylinder and reaction ring are normal, etc., to ensure that the top drive plug can function stably and reliably.
