drill collar การใช้

• Type 3 uses the drill collars to achieve directional control.
• If a short drill collar is used, then the stabilizers can be even closer together.
• This is because these sensors are compact, inexpensive, reliable, and can take measurements through unmodified drill collars.
• The nearly two-mile-long drill string was equipped with a 14 3 / 4-inch drill bit and 10-inch drill collars.
• Collar-mounted tools, also known as " fat tools ", cannot generally be removed from their drill collar at the wellsite.
• Typical applications for alloy K-500 are : pump shafts and impellers, doctor blades and scrapers, oil-well drill collars and instruments and electronic components.
• The aerospace division of Sheffield also provides technology testing to steel and metals producers and makes drill collars and other products for the oil and gas industry.
• When the fishing jar releases the stored energy in the compounder / acclerator lifts the drill collars upwards at a high rate of speed creating a high impact in the jar.
• Usually 2 to 3 stabilizers are fitted into the BHA, including one just above the drill bit ( near-bit stabilizer ) and one or two among the drill collars ( string stabilizers ).
• Weight on bit is provided by drill collars, which are thick-walled tubular pieces machined from solid bars of steel, usually plain carbon steel but sometimes of nonmagnetic nickel-copper alloy or other nonmagnetic premium alloys.
• The BHA will be made of thicker walled heavy weight drill pipe ( HWDP ) and drill collars, which have a larger outside diameter and provide weight to the drill bit and stiffness to the drilling assembly.
• A wide variety of products and parts are manufactured, including underground cranes, shield haulers, rifle barrels, steam locomotive parts, drill collars, turbine parts, gears, sprockets, and splines for the oil fields, steel mills, coal mines, trona mines, power plants, other machine shops, manufacturers and other industries in many capacities.
• These rams are designed to sever and seal off the well on the ocean floor; however in this case the drill collars had been brought in line with the BOP and the BOP rams were not able to sever the thick steel walls of the drill collars leading to a catastrophic blowout.
