Description

China Vigor Drilling Oil Tools And Equipment Co., Ltd. is one of the most professional manufacturers and suppliers of heavy weight drill pipe（hwdp） in China, featured by competitive price and fast delivery. Welcome to buy high quality heavy weight drill pipe（hwdp） in stock here from our factory.

Heavy Weight Drill Pipe(HWDP)was developed to provide a gradual transition from heavy drill collars to relatively lightweight drill pipe. This intermediate-weight pipe helps prevent stress concentration at the top of the drill collar section. Heavy weight drill pipe also enables drilling at higher RPMs, reducing torque and differential pressure sticking. Vigor could provide different sizes HWDP with hard band you required.

Heavy Weight Drill Pipe(HWDP) is well-suited for directional drilling applications. Because it bends easily, heavy weight drill pipe simplifies directional control and minimizes connection fatigue problems that are common in high-angle or horizontal drilling.

For extended reach and horizontal wells, high-strength heavy weight drill pipe is often used high in the hole to apply weight on the bit. This is especially true for wells in which the total vertical depth to total measured depth ratio is low.

Applications

1. Directional Drilling: In directional drilling, HWDP plays a vital role in guiding the drill bit along a predetermined path. The added weight and stiffness of HWDP help maintain a straight drilling trajectory while minimizing deviation and avoiding costly drilling errors.

2. Horizontal drilling: Horizontal drilling presents unique challenges in maintaining the correct weight and torque for the drill bit. HWDP can help provide the necessary weight and stiffness to keep the bit on the course, even when drilling at extreme angles.

3. Deep Drilling: When drilling at deep depths, the weight of the drill string can become a limiting factor. HWDP can help add the necessary weight to the drill string, allowing it to reach greater depths and extract more oil or gas.

4. Development of unconventional reserves: Unconventional reserves such as shale gas and oil sands require specialized drilling techniques to access. Heavy Weight Drill Pipe(HWDP) is often used in conjunction with these drilling techniques to improve drill string stability and performance.
