Parts & Components of Oil Drilling Rigs

© www.tradequip.com PARTS & COMPONENTS OF OIL DRILLING RIGS 66 Oil is a very important component of economic growth. Maria Bartiromo Oil Drilling Rigs Parts & Components – A Depiction 1.Crown Block 15. Derrick or Mast A muster of pulleys that is mounted on beams at the top of derrick. Used for lifting and positioning the drill string and all machinery necessary for turning the drill string above the well bore. 2.Top Drive 16.Traveling Block A motor suspended from the derrick used to turn the drill string during driling operations. A top drive replaces the traditional Kelly or rotary table and lessens the manual labor involved for the drilling process Comprised of pulleys or sheaves through which wire rope is threaded. More sheaves enables heavier loads. 13 17.Engine Generator 3.Doghouse on Driller's Shack Sets It consists of engines, generator anda mechanical transmission to produce power for the driling rig Onshore it acts as an office for a driller and a storehouse for minor entities. Offshore it acts as an enclosure for electronics that controls the equipment on the rig floor 15 18.Drawworks A machine consisting of a large-diameter spool, brakes and power source, used in reeling in and out of the drilling line. 4.Blowout Preventer [Pipe ram & blind ram] Uses rams to seal pressure. It comes with interchangeable ram blocks that accommodate various O.D. drill pipe, casing. tubing, etc. 5.Drill Pipe The drill pipe facilitates the process of wellbore drilling. It revolves the drill bit and circulates the drilling fluid. 6.Drill Bit A module attached at the end of the drill bit. It breaks or crushes rock structure that come in contact while driling a wellbore. 19. Mud Tanks Mud tanks are used to store driling fluid and are made up of steel fubes and steel plates 7.Mud Pump A component whose purpose is to dispense fluid down to the drill string and then bock to the annulus under high pressure (about 52.000 kPa) 11 8.Shale Shakers Consists of sieves/screens that removes drillcuttings and other solids present in the fluids used for drilling operations. The sieve/screen size is chosen based on the size of the solids 21 O 9.Mud Gas Separator It separates the mud and the gas that comes out from the well 20.Mud Pit It is an excavated earthen pit in which drilling fluid would be stored. The pit is lined with plastic to prevent the soil from mixing with the fluid. 10.Pipe Racks Used to stockpile pipes. power cables and instrument cable trays. Also supports mechanical equipment. vessels and valve access platforms 21.Choke Manifold It is an assembly of pipes and valves. Driling mud is circulated through this when the blowout preventers are shut to control the pressure encountered during a kick 22.Fuel Tank 11.Pipe Ramp It is used as a pathway for moving the drill pipe up to the driling platform as well as to bring them down It stores fuel in large quantity that is required for rig generators and other rig equipment 23. Water Tank 12.Accumulator It stores water that would be used for mixing mud. cementing and rig cleaning It stores nitrogen pressurized hydraulic fluid that is required to operate the blowout preventers 24.Catline Boom & Hoist Line 13.Monkey Board Catline Boom is used to lift heavy materials. It is erected near the top of the derrick. Hoist Line is power-driven by the cathead that lifts heavy A platform on which the derrick man works while tripping pip 25.Drilling Line A thick, stranded metal cable threaded through the traveling and crown blocks used to raise & bring down a drill string 14.Electrical Control Room Engines run electric generators that produce electricity. The produced electricity is transferred to the distribution panel via cables. 26. Electric Cable Tray It is a supportive platform for heavy cables that feed power to the rig motors It is then used to feed the electric motors on the rig Tradequip INFOGRAPHIC PRESENTED BY International tradequip.com The Energy Equipment MarketPlace
