What is a drill pipe and what are the uses of the drill pipe

A drill pipe is a steel pipe with a threaded tail that connects the surface equipment of a drilling rig to a drilling and grinding equipment or a bottom hole device located at the bottom end of the drilling well. The purpose of the drill pipe is to transport the drilling mud to the drill bit and with the drill bit to raise, lower or rotate the bottom hole device. The drill pipe must be able to withstand tremendous internal and external pressure, twisting, bending, and vibration.

In the process of oil and gas extraction and refining, the drill pipe can be used multiple times.

1. According to the test comparison or the product recommendation of our factory, the right type of chisel is selected.

2. The company's conical brazing products have the "G" trademark at the rod body and the collar plate, from the rod body to the end, the collar plate "G" opening to the right is concave, the rod body is convex marking, and the excellent brazing is marked as "G" G and "G" Pu brazing is marked as "G", "G-1".In order to track the quality of the product, the brazing body also has the production lot number on it.

3. It should be ensured that the drill rod and the drill bit are well matched (the taper is consistent); If the chisel taper is less than the taper of the chisel bit, it is easy to break the tip tip.

4. For the depth of the rock drilling hole, it is recommended to use the sleeve rod, that is, the short drill rod is used to open the hole first, and then the long drill rod is used to continue to extend the hole, so as to improve the service life of the drill rod (according to the hole depth, 2 sets of drills or 3 sets of drills can be used).

5. The opening should be stable, appropriately reduce the propulsion air volume, and avoid the chisel rod working in a bent state, otherwise the service life of the chisel rod will be shortened.

6. In the process of punching and exiting, try to avoid the bending force of the drill rod to improve the service life of the drill rod.

7. The air volume of the rock drill should be adjusted according to the site conditions (rock conditions) to ensure the normal operation of the rock drill.

8. For the rock condition of the drill, a cross-shaped drill bit should be used.

9. The user shall not change the structure of the drill rod at will or use it after reprocessing, so as not to affect the normal service life of the drill rod.

10. When the normal use of ordinary chisel is prone to batch early fracture, it should be replaced with excellent brazing; When the excellent drill is not used, the large size drill rod should be replaced, or the air pressure should be reduced.

11. The diameter of the chisel rod body should match the power of the rock drill, and the large size chisel should be selected if the power is large.

It is mainly used in the construction of deep wells, horizontal wells and extended-reach wells in the process of oil and gas exploration and development.

1. Transmit torque.

2. Conveying medium.

1. The oil drill pipe is a seamless steel pipe made of tie.

In order to strengthen the connection strength between the pipe body and the joint, the two ends of the drill pipe body are thickened and thickened.

2. Drill pipe is a steel pipe with a thread at the tail, which is used to connect the surface equipment of the drilling rig and the drilling and grinding equipment or bottom hole device located at the bottom end of the drilling well. The purpose of the drill pipe is to transport the drilling mud to the drill bit and to raise, lower or rotate the bottom hole device in conjunction with the drill bit. The drill pipe must be able to withstand tremendous internal and external pressure, twisting, bending, and vibration.

In the process of oil and gas extraction and refining, the drill pipe can be used multiple times. Drill pipes are divided into three categories: square drill pipe, drill pipe and Gasen megaweight drill pipe. The connection sequence is square drill pipe (1) + drill pipe (n, determined by the depth of the well) + weighted drill pipe (n, determined by the combination design of drilling tools).

Jining Xingwang Machinery Manufacturing Co., Ltd. produces a relatively complete range of bolts.

What is the specific explanation of drill pipe, we will introduce it to you through the following aspects:

1. Online explanation [click here to view the details of the plan].

Drill pipe drill pipe is a steel pipe with a grain at the tail, which is used to connect the surface equipment of the drilling rig and the drilling and grinding equipment or bottom hole device located at the bottom end of the drilling well. The purpose of the drill pipe is to transport the drilling mud to the drill bit and together with the drill bit to raise, lower or rotate the bottom hole device. The drill pipe must be able to withstand tremendous internal and external pressure, twisting, bending, and vibration.

In the process of oil and gas extraction and refining, the drill pipe can be used multiple times. Drill pipes are divided into three categories: square drill pipe, drill pipe and weighted drill pipe. The connection sequence is square drill pipe (1) + drill pipe (n, determined by the depth of the well) + weighted drill pipe (n, determined by the combination design of drilling tools).

The classification of drill pipes, drill pipe joints, drill pipe specifications, and the steel grade and strength of drill pipes are introduced in detail.

The service life of the drill pipe is mainly related to the part connected to the drilling rig and its material.

In China, 45 mnmob, 40 mn 2movnb and 40mn 2mo isoplasm strength low alloy steel are used for rope core drill pipes, with a service life of up to 6000 meters. The Belgian company Diamant Boart produces rope core drill pipes with an average service life of 7,000 meters.

The drill pipe is a steel pipe with a thread at the end, which is used to connect the surface equipment of the drilling rig to the drilling and grinding equipment or bottom hole device located at the bottom end of the drilling well. The purpose of the drill pipe is to transport the drilling mud slurry to the drill bit, and to raise, lower or rotate the bottom hole with the drill bit. The drill pipe must be able to withstand tremendous internal and external pressure, twisting, bending, and vibration.
