HEAVY WEIGHT DRILL PIPE
Founded in 2013, Yantai Xinbaoshang Materials Technology Co., Ltd.
China's leading heavy weight drill pipe manufacturer and supplier
Heavy Weight Drill Pipe (HWDP) is a critical component in the oil and gas industry, specifically designed to meet the demands of modern oil and gas drilling operations. HWDP products are manufactured using high-strength steel, offering exceptional wear resistance and corrosion resistance, enabling reliable performance under extreme conditions. They play a crucial role in the drilling string, primarily used to increase drill bit downforce and stability, thereby enhancing drilling efficiency. The unique design of HWDP includes thicker walls and a heavier structure. This additional weight helps enhance the drill bit's drilling capability, particularly in soft soil or unstable formations, reducing the risk of drill bit vibration and twisting, and ensuring smoother drilling operations. Each HWDP is subject to rigorous quality testing and meets API standards.
HWDP acts as a transition member between the stiff drill collars and the more flexible drill pipe, helping to reduce stress concentration and fatigue failures in the drill string.
The increased weight and stiffness of HWDP can be used to provide more weight on the drill bit, which is crucial for efficient drilling, especially in hard or abrasive formations.
HWDP is particularly useful in directional and horizontal drilling where maintaining the desired wellbore trajectory and minimizing deviation are critical. The flexibility of HWDP can help navigate bends and curves in the wellbore, while its stiffness helps control the drilling direction.
In deep drilling operations, the weight of the drill string can become a limiting factor. HWDP can help add weight to the drill string, allowing it to reach deeper depths and improve drilling efficiency.
The thicker wall of HWDP helps prevent buckling, especially in the transition zone, and can also reduce the risk of differential sticking, where the drill string gets stuck due to pressure differences.
The increased stiffness of HWDP can also contribute to better hole cleaning by improving the flow of drilling fluids, which helps remove cuttings and debris from the wellbore.
By acting as a buffer between the drill collars and drill pipe, HWDP helps reduce the stress and fatigue experienced by the drill string, leading to longer component life.
As a leading manufacturer and supplier of heavy weight drill pipe products in China, our products cover most application scenarios in terms of size and standards. Our products strictly comply with international standards such as API and ASTM. If you have any other requirements for product specifications, please feel free to contact us for customization.
| Outer Diameter (OD) | HWDP typically ranges from 2 7/8″ to 6 5/8″ in outer diameter. |
| Steel Grade | HWDP is commonly made from AISI 4145H modified alloy steel or proprietary alloys like DPM-65MS or DPM-HW90SS. |
| Weight Range | Weights can vary widely, but some examples include 6.27#/FT through 27.72#/FT as listed by Drilling Manual, with heavier options available. |
| Lengths | HWDP is available in lengths similar to standard drill pipe, typically categorized as Range 2 and Range 3. |
| Tool Joint Connections | Common tool joint connections include NC38, NC46, NC50, and 5-1/2 FH. |
| Standards | HWDP is manufactured to meet API 7 and API 5DP standards. |
| Material Properties | The material needs to meet the mechanical properties specified in API Spec 7-1. |
| Wall Thickness | HWDP has thicker walls than standard drill pipe, often three times thicker for similar sizes. |
| End Finishes | Common end finishes include Internal Upset, External Upset, Plain End Upset, and Non Upset. |
