Drill Collar

Drill Collar is the basic component in the BHA which provides weight on the bit for drilling and keeps the drill string in tension. JX Petro Drill Collar is manufactured from AISI 4145H modified quenched and tempered steel and is heat treated along its entire length for uniform toughness and durability. Strict metallurgical tests are performed per specifications to ensure that the heat treatment produces consistent and maximum hardness through the depth of the bar.

  • Hardness range of 285 to 341 BHN and a Charpy impact value of 40ft/lbs is guaranteed for evenly distributed 16 points in any cross sections at room temperature.
  • Connections as phosphate coated father machining to protect the threads from corrosive elements and to prevent galling upon initial make-up. Thread roots are cold rolled on API and H0-90 connections.
  • Pressed steel thread protectors are supplied to all drill collars that is equipped with standard connections.
  • Manufactured strictly according to API standards.
  • Widely used in oil, gas, HDD, and a geothermal field

Description

Drill collars are an essential component of the Bottom Hole Assembly (BHA) that provides weight on the bit for effective drilling. These heavy-duty pipes help maintain the drill string in tension and enhance the stability of the drilling process. Our drill collars are manufactured using AISI 4145H modified quenched and tempered steel, ensuring uniform toughness and high durability. The entire length of the drill collar undergoes heat treatment, and rigorous metallurgical tests are conducted to guarantee consistent hardness and maximum performance.

 Drill Collar 

Drill collars are vital for providing weight on the drill bit, reducing vibration, and ensuring precise drilling operations. They are thicker and heavier than standard drill pipes, which allows them to exert significant force downward while keeping the drill string stable. The three main types of drill collars available are:

Drill Collar

  • Slick Drill Collars: These have a smooth external surface and provide additional weight without increasing drag.

  • Spiral Drill Collars: These have helical grooves along their length to reduce the chances of differential sticking.

  • Non-Magnetic Drill Collars (NMDCs): These are used in environments where magnetic interference needs to be minimized.

All drill collars undergo stringent quality control measures and comply with industry standards to ensure superior performance and longevity.
