Drill collars provide essential weight-on-bit for efficient drilling while stabilizing the drill string, reducing vibration, and controlling wellbore angle. Manufactured from API 4145H steel with full heat treatment, our seamless integral and spiral types (API Spec 7-1) offer superior strength and anti-sticking performance for reliable downhole operation. If you want to know more about drill collars, please do not hesitate to contact the drill rod making machine supplier.
Critical Weight & Stabilization: drill collar provides essential weight-on-bit for effective drilling while stabilizing the drill string, reducing vibration/swing, and controlling wellbore angle to ensure precise, efficient operations.
Engineered Anti-Sticking Performance: Spiral grooves (on spiral types) minimize well wall contact, preventing differential sticking. Made of API 4145H steel with full heat treatment for maximum durability in demanding conditions.
Core Functionality & Stability: drill collar provides essential weight on bit for drilling while keeping drill pipe in tension. This significantly reduces bit vibration, swing, and bouncing, ensuring smoother operation and better wellbore control.
Anti-Sticking Design: drill collar has spiral grooves that minimize contact area with the wellbore wall. This design effectively prevents dangerous pressure differential pipe-sticking incidents during operations.
High Material Quality & Durability: Manufactured from high-strength 4145H alloy steel with full-body heat treatment. Threads receive phosphate coating, enhancing overall toughness, wear resistance, and longevity in demanding downhole environments.
Compliance & Customization: Strictly adheres to API Spec 7-1 standards for quality and interchangeability. Offers flexibility for customized production to meet specific customer requirements or unique well conditions.
