Drill Collars
Quipsearch supplied drill collars are made from AISI 4145H alloy steel. They are quenched and tempered to obtain mechanical properties as specified by API Spec 7-1. Full mechanical and chemical mill test certifications are supplied with all drill collars.
Drill collars are supplied as slick or spiralled, generally in Range 1, 2 or 3 lengths. All Drill Collar connections are precision-machined to API Spec 7-2 requirements. API relief groove pin and bore-back box stress relief are available on request. All connections are phosphate coated to minimize galling during makeup and thread storage compound is applied. Shock-resistant steel thread protectors are installed to ensure adequate joint protection during shipment.
Slip and elevator recesses can be added to our drill collars to improve handling efficiency and safety. Unless otherwise specified, slip and elevator recesses are machined in compliance with the latest API RP7G edition guidelines and can be provided together or separately.
Quipsearch supplied drill collars are available with the following features:
- Slick or spiral
- Mechanical properties guaranteed to 1″ below the steel’s surface at ambient temperature
- Phosphate-coated threads to prevent galling
- Slip or elevator recesses, or both
- API stress-relief and bore-back hard-banding and internal plastic coating upon request
Heavy Weight Drill Pipe (HWDP)
Quipsearch offers HWDP over a wide variety of sizes including pipe bodies from 2 7/8″ to 6 5/8″. Our HWDP has a central upset with 2 bands of hard-banding material which reduces drag and wear. The central upset is available in slick, spiral, full spiral, or tri-spiral designs. Pipe bodies and tool joints are assembled through friction welding as part of an integrated production process. Every joint is manufactured from specific steel alloys ensuring predictable performance and tight tolerances.
HWDP provides a gradual transition between drill pipe and drill collars. The HWDP’s main function is to provide extra WOB (weigh on bit) helping with directional control of the BHA in complex wells. It also reduces drill string fatigue in horizontal and ERD wells. HWDP mitigates differential sticking and can provide additional weight for milling, under-reaming, and hole-opening operations.
