Drilling operation method of drill pipe

Drill pipe operating methods and cooperation methods:

1. Basic functions of drill pipe
Drill pipe is an important tool for transmitting rotational force and propulsion during the oil drilling process, and is used to connect drilling equipment. The drill pipe is usually composed of several sections of pipes with the same bite. They are connected through the bite to transmit the rotational force and propulsion force to the drill bit to achieve rotation and drilling during the drilling process.

2. How the drill pipe and drill bit fit together

The cooperation between drill pipe and drill bit is one of the most basic cooperation methods in the drilling process. The drill bit is a tool used to extract oil and gas resources, and the drill pipe is an important tool for transmitting the motion force of the drill bit to the bottom of the well. The two must work closely together to ensure the smooth progress of drilling work. The drill bit is fixed on the drill shank and connected to the drill pipe to complete the crushing and cutting of rock formations while rotating and drilling.

3. Cooperation between drill pipe and flushing
Drilling flushing has always been a very important link during drilling operations. Flushing is a way for drilling fluid to flow from the inside of the well to the wellhead. In addition to cooling down and reducing friction, it also removes debris and rock powder at the bottom of the hole to ensure normal work. The drill pipe needs to cooperate with the flushing faucet, flushing pipe, etc., so that the drilling fluid can flow smoothly and at the same time stir it with the rock formation.

4. Cooperation between drill pipe and lifting
The cooperation between drill pipe and lifting is mainly completed underground. Lifting refers to the process of sending drilling tools downhole or taking them out from downhole, which needs to be completed with the help of drilling rig lifting equipment. The drill pipe needs to cooperate with the drilling rig hook, drilling cable, etc., so that the driving device can pull and coordinate the drill pipe to realize the lifting and lowering of the drilling equipment.

Summarize:

To sum up, drill pipe is an important tool in the oil drilling process. Only by working closely with the drill bit, flushing, lifting and other methods can the smooth progress of the drilling process be ensured. In actual drilling operations, the selection and use of drill pipes need to be reasonably matched according to conditions such as rock formations and well depths to ensure the efficiency and safety of drilling operations.

Tips: Although casing pipe and drill pipe have different structures and uses, they are related to each other. That is, during the drilling process, the casing is fed into the wellbore layer by layer through the drill pipe and penetrates the drill pipe. It is the bridge between surface equipment and downhole operations, and the two are closely related.
