What Is a Drill Collar?
Drill collars are devices utilized at the lowest point of a drill string and remain an important component of the bottom hole assembly. These lead collars are very thick-walled tubes that apply weight to a drill bit. Typically, a drill collar is manufactured with threads at both ends, with male threading on one side and female threading on the other.
At CSS Drilling Tools, we understand the unique requirements of the drilling industry. That's why we offer high-quality lead collars designed to meet your unique needs. Our products are carefully engineered for durability, performance, and reliability, enabling you to tackle drilling projects with confidence.
Different Types of Drill Collars
Did you know that there is more than one classification for drill collars? In fact, there are three, and they’re categorized by structure and material: slick collars, spiral-grooved collars, and non-magnetic drill collars.
Slick Drill Collar
Slick drill collars (as the name suggests) typically are constructed as smooth, slick-walled tubes about four to eight times the thickness of drill pipes. These collars are machined to a uniform cylindrical shape and can be fabricated with plain alloy steel.
Spiral-Grooved Collar
These drill collars are typically about four to six percent lighter in weight than slick drill collars. These spiral-grooved collars are widely used due to their spiral design, which reduces the likelihood of sticking accidents, thus decreasing the area of contact between the collar and the wall.
Non-Magnetic Collar
These drill collars are manufactured from a non-magnetic steel alloy material. In some cases, magnetic measuring tools can pick up the geomagnetic field when measuring the direction of a borehole, so these tools must be paired with non-magnetic collars to function properly.
What Are Pup Joints?
In drilling, a pup joint, also called a spacer joint, is a casing, pipe, or tubing that has a shorter length compared to a standard tubular string. This non-uniform length allows for adjustments and installation of tools and other tubular components when downhole placement is necessary for a specific project.
Pup joints are a necessary component when drilling just about any well. Because of their shorter length, they’re easy to handle and use, while also providing identical performance as the drill pipe, tubing, or casing that they are attached to.
