DRILL COLLAR

 

 

 

 

 

 

1. Introducing the superior material choices for our API 7-1 Non-Magnetic Drill Collar and Slick Drill Collar. With an outer diameter ranging from 79.4mm to 279.4mm, crafted using the robust 4145H/4145H mod or non-magnetic material, ensuring durability and performance.
2. Our products adhere to the most stringent standards: API 7-1 and NS-1, guaranteeing the highest level of quality and reliability.
A. Slick Drill Collar
Note: The drill collar is an indispensable tool designed to apply weight on the drill bit, allowing for efficient drilling by keeping the drill pipe under tension. The slick drill collar, in particular, is engineered to
maintain the drill bit's central position and ensure precise hole trajectory, thanks to its significant rigidity. Our drill collars are produced with unwavering commitment to API Spec7-1 and
SY5411 standards, promising top-notch performance.
B. Spiral Drill Collar
Note: Our innovative spiral drill collar is specifically designed to minimize contact with the borehole, effectively preventing bit sticking caused by differential
pressure. Each drill collar is meticulously manufactured according to API Spec7-1 and Standard SY5144, ensuring exceptional quality and reliability.
C. Spiral Drill Collar With Elevator Groove And Slip Groove
Note: The expertly crafted elevator and slip grooves on the box thread face of our slick or spiral drill collars double as lifting subs and safety slips during tripping out operations.
These grooves meet the precise technical parameters set by API SPEC7-1. Optional hardbanding is available to meet specific customer requirements.
D. Non-magnetic Drill Collar
Experience enhanced performance with our non-magnetic drill collars, featuring a unique cold-rolled finish on both the inner and outer surfaces. This innovative process strengthens the structure,
offering unrivaled resistance to stress, corrosion, and cracking, while significantly boosting mechanical performance.
Specifications for API 7-1 Non-Magnetic Drill Collar Slick Drill Collar are available with an OD range of 79.4mm to 279.4mm, tailored to meet the most demanding drilling requirements.
