Top drive plug is an important equipment in petroleum drilling engineering, used to control the pressure and flow rate at the wellhead, thereby protecting the safety of wellhead equipment and drilling personnel. It is a high-tech product with a complex structure, flexible use, and high requirements for technical personnel.
There are two main working principles for the top drive plug in Xinjiang: one is to use rotational force to drive the drill bit and achieve rotary drilling; Another way is to control the entry and exit of the drill bit into the wellbore through pressure interaction.
In drilling engineering, the application of top drive plugs mainly includes the following aspects:
1. Prevent contact between the top roller and the work platform
The top drive plug can achieve the rotation of the top roller, thereby avoiding contact with the work platform. This not only improves work efficiency, but also ensures work safety.
2. Control wellhead pressure
The top drive plug can control the wellhead pressure, thereby ensuring the safety of wellhead equipment and drilling personnel. It can be adjusted in a timely manner according to the situation of the wellhead to ensure its stability.
3. Control the flow rate of drilling fluid
The top drive plug can control the flow rate of drilling fluid, thereby affecting the drilling speed. Properly adjusting the flow rate of drilling fluid can improve drilling efficiency, reduce working time and costs.
4. Drill bit entering and exiting the wellbore
The top drive plug can also control the speed and direction of the drill bit entering and exiting the wellbore, and appropriate adjustments can improve drilling efficiency and reduce work costs.
