Spiral Drill collar

The major function of spiral drill collar: It is to prevent drilling tools from pressure differential block during drilling, the spiral groove allows the mud flow freely around the drill collar to balance pressure preventing pressure block, so effectively avoid bit sticking from differential pressure. Spiral collar can also reduce the contact area between the wall and tubular body, so as to avoid from sticking phenomenon of drill string.

Product Description

Product Description
API 7 Oil Well Drilling Spiral Non-Magnetic Drill Collar
1) Standard: API Spec 7
2) API and ISO certified
3) Specification: 3-1/8'', 3-1/2'', 4-1/8'', 4", 4-3/4'', 5'', 6" 6-1/4", 6-3/4", 7", 7-1/4", 7-3/4", 8", 8-1/4", 9", 9-1/2", 9-3/4", 10", 11"
4) Material: Alloy Steel
5) Description
A drill collar is a device used in the drilling of oil wells for weighting the drill bit, enabling it to drill through rock. It is a bar made of solid steel, either plain carbon steel or a non-magnetic steel alloy, drilled lengthwise to permit the passage of drilling fluids. A drill collar forms the lowest element of a drill string, which encompasses all the elements of a down-hole process from the surface to the rock bit.
6) Structure
These devices are typically 31 feet (about 9.45 m) long and threaded at both ends, male at one end and female at the other, to allow multiple drill collars to be joined above the bit assembly.
The number of drill collars attached to a drill string will depend upon the material composition of the strata at the drill site and the likely depth of the well. A relatively shallow well with less dense geologic structure through which the bit must pass will require fewer drill collars than a deep shaft through dense material.
Typically, drill collars will be consistent in length but may vary in diameter, and their outside configuration may be slick or spiral. The outside diameter may vary from about 3-1/2 inches (8.89 cm) to 11 inches (27.9 cm) and greater. The reference to slick or spiral outer configuration refers to the machining of the outside surface of the collar.

7) Characteristic of Non-mechanical Drill Collar
Materials of Non-magnetic drill collars are made from chrome manganese low carbon austenitic alloy, which has following characteristic:
a. The chemical composition should be controlled strictly during the refining and forging process.
b. With excellent lower Magnetic permeability, high strength of mechanical properties and outstanding resistant to stress corrosion cracking and no tendency to galling.
