Drill Collars - Drilling Tubulars - E&M Supply Group

While drill pipe makes up the majority length of a drill string, drill collars make up only a small amount. For example:a 10,000ft drill string may be comprised of 9,000ft of drill pipe, and only 500ft of drill collars. Much like drill pipe, drill collars are made in 31ft lengths and Drill Collars - NOVDrill collars are trepanned and drifted to API Spec. 7-1. Full-length heat-treatment processes ensure mechanical properties meet or exceed API Spec. 7-1 requirements. A hardness range of 285-341 Brinell hardness and Charpy V notch minimum impact strength of 40 ft

Drill Pipe Heavy Weight Chart Download Drill Pipe Heavy

Drill pipe heavy weight is a type of drill pipe with thickened walls and longer collars compared to the standard drill pipe. This provides the heavy weight drill pipe (HWDP) with higher tensile strength. To facilitate greater support, HDWP is positioned near the topmost part of a long drill string. Drill Pipe Heavy Weight Specifications Drill Pipe Selection Guide Engineering360Heavy weight drill pipe (HWDP) is a tubular pipe that adds weight or acts as a transitional piece in the drill string. As a transitional section of the drill string, it is placed between the drill collar and standard drill pipe to reduce fatigue failures. In other applications the HWDP is used as an additional weight to weigh down the drill string.

Drill Pipe and Heave Weight Drill Pipe Specifications

Heavy Weight Drill Pipe. Heavy weight drill pipe is a medium-weight drilling pipe, (referred standards in API SPEC 7-1). It has bigger wall thickness than common drilling pipe and smaller than drill collar. The tube is connected with special length-added drill pipe joint (integral heavy weight drill pipe is made up of tube and tool joint).

Other articles where Drill collar is discussed:petroleum production:The drill pipe:pipe are extra-heavy sections called drill collars, which serve to concentrate the weight on the rotating bit. In order to help maintain a vertical well bore, the drill pipe above the collars is usually kept in tension. The drilling mud leaves the drill pipe through the bit in such a HEAVY WEIGHT DRILL PIPES - COMMAND-SMFIStandard heavy weight drill pipe (HWDP) is supplied with AISI 1340 steel or equivalent in the pipe body and AISI 4145H or AISI 4140H-modified tool joints. The welded assembly is the standard offer whereas the integral version is considered optional due to plant availability.

Heavy Weight Drill Pipe - Equipoutlet

Heavy weight drill pipe is also utilized in the horizontal directional drilling (HDD) industry for added strength in high stress situations. Heavy weight drill pipe (HWDP) may be used to make the transition between the drill collars and drill pipe. The function of the HWDP is to provide a flexible transition between the drill collars and the Heavy Weight Drill Pipe - NOVThis intermediate-weight pipe has a wall thickness of approximately 1 in. and helps prevent stress concentration at the top of the drill collar section. Heavy weight drill pipe also enables drilling at higher RPMs, reducing torque and differential pressure sticking. Heavy weight drill pipe is well-suited for directional drilling applications.

Petropedia - What is Drill Collar? - Definition from

A Drill Collar is a tubular piece of a drill string which provides weight on the bit for the purpose of drilling. While drill pipes make up the majority length of drill strings, drill collars make only a small amount. They have thick walls machined from the solid bars of steel.
