The difference between drill pipe and heavy weight drill pipe

SVES Oilfield Supply Co., Ltd is a leading supplier and provider of drill pipe and heavy weight drill pipe (HWDP).

Today here we are talking about the difference between drill pipes and heavy weight drill pipes (HWDP) in the followings.

I. The structural difference between heavy weight drill pipes (HWDP) and drill pipes.

The heavy weight drill pipe (HWDP) is to increase the mass of the inner filling (drill pipe weight block) of the drill pipe and increase the weight of the heavy weight drill pipe (HWDP). The main structure of this drill pipe is tubular and can be filled with sand, steel balls and other materials.

The drill pipe is made of steel pipe, which has a certain strength and toughness, and the internal structure is hollow, which is convenient for the circulation of drilling liquid.

2. The material difference between heavy weight drill pipes (HWDP) and drill pipes.

The heavy weight drill pipe (HWDP) is usually made of a special alloy steel that can withstand extreme environments such as high temperatures and pressures, while at the same time making it more resistant to corrosion through special treatments. The drill pipe, on the other hand, is made of relatively common high-strength steel and is specially designed for the needs of the drilling industry.

3. The use occasions and purposes difference between heavy weight drill pipes (HWDP) and drill pipes.

Heavy weight drill pipes (HWDP) are often used in high-density drilling, such as in the detection and exploitation of underground holes such as oil wells and natural gas wells. Its weighted design helps the drill bit to penetrate the formation quickly, greatly improving the efficiency of drilling.

Drill pipes are also widely used in the drilling industry, and drill pipes of different lengths, diameters and structures can be selected according to specific drilling conditions and drill bits to meet the different needs of drilling.

4. The use frequency difference between heavy weight drill pipes (HWDP) and drill pipes in the drilling industry.

In the field of oil drilling, the drill pipe is a common drilling tool, while the heavy weight drill pipe (HWDP) is special because it is suitable for drilling under special conditions. Therefore, in general, the frequency of use of heavy weight drill pipe (HWDP) is comparatively low, while the frequency of use of drill pipes is higher.

5. Maintenance difference between heavy weight drill pipes (HWDP) and drill pipes.

The manufacturing cost of heavy weight drill pipe (HWDP) is high, so it is necessary to pay attention to maintenance during use to avoid damage and wear of heavy weight drill pipe (HWDP), resulting in shortened service life. The drill pipe is relatively simple and has low maintenance requirements.
