How to judge the performance of the top drive plug?

Top drive plug is an important drilling equipment that can achieve rotation and sealing of the wellhead, improving drilling efficiency and safety. When using the top drive plug, attention should be paid to its structure and working principle, and correct operation and maintenance should be carried out. Only by using the top drive plug correctly can the pressure and fluid at the wellhead be effectively controlled, ensuring the smooth progress of drilling operations.

With the increasing depletion of oil and gas resources and the difficulty of extraction, the technology of top drive plug valves is also constantly innovating and developing. The new top drive plug not only has higher sealing performance and durability, but also can achieve remote control and automated operation, thereby improving work efficiency and safety. In addition, some drilling companies have also developed intelligent top drive plugs, which can achieve real-time monitoring and early warning through technologies such as sensors and data analysis, further improving the efficiency and safety of drilling operations.

How to judge the performance of the top drive plug?

Need to consider the working capacity of the top drive plug. The work ability mainly includes indicators such as maximum torque, maximum thrust, and maximum tension. The maximum torque refers to the maximum torque force that the top drive plug can output, which is generally used for conditions such as drilling in and out of drill collars, drilling joints, etc. The maximum thrust refers to the maximum thrust force that the top drive plug can output, which is generally used for impacting or pushing drilling tools, breaking scale layers, and other working conditions. The maximum pulling force refers to the maximum pulling force that the top drive plug can output, which is generally used to pull out drilling tools, restore blockages, and other working conditions. The greater the working capacity and adaptability of the top drive plug, the better its performance.

Secondly, the stability and durability of the top drive plug need to be considered. Stability is mainly reflected in the vibration and noise during the operation of the top drive plug. The top drive plug should have good dynamic performance, which can reduce vibration and noise, and improve the smoothness and comfort of drilling operations. Durability refers to the ability of the top drive plug to work stably for a long time, without being prone to failure and wear. The top drive plug should have a sturdy structure and be made of high-strength and wear-resistant materials to improve its durability and service life.

Thirdly, it is necessary to consider the control accuracy and operational convenience of the top drive plug. The control accuracy is mainly reflected in whether the top drive plug can accurately and stably respond to operating instructions and meet the working requirements of various working conditions. The control system of the top drive plug should have high-precision sensors and advanced control algorithms to ensure that the control accuracy meets the requirements. The convenience of operation refers to whether the operation mode of the top drive plug is simple, convenient, easy to master and operate. The control system of the top drive plug should be designed reasonably, with a user-friendly interface and clear operating logic to improve work efficiency and facilitate human-machine interaction.

Top drive plug is a rotary sealing device installed at the wellhead, mainly composed of top wheel, plug body, sealing gasket, transmission device, etc. The top wheel is an important component of the top drive plug, which drives the plug body to rotate through the torque transmitted by the top wheel and seals the wellhead through a sealing gasket. The transmission device of the top drive plug usually adopts the form of a transmission sprocket and chain, so that the plug body can rotate smoothly.

In the development of oil fields in China, top drive plugs have been widely used. For example, Changqing Oilfield conducted in-depth discussions and research on the application of top drive plugs during a large-scale geological model seminar on oil and gas field production. By optimizing and improving the structure and process of top drive plugs, Changqing Oilfield has successfully achieved efficient development and production of large-scale oil and gas fields.
