System used in Rotary drilling

 System used in Rotary drilling.

          

              There are five system used in Rotary drilling.These systems are given below,

       1: Hoisting System.

       2: Rotary System.

       3: Circulating System.

       4: Power System.

       5: Well control System.

    1: Hoisting System :

           Hoisting System is the system 

used on a drilling rig to

          perform all lifting activities on the rig. These activities basically 

          include the lowering and lifting of necessary equipment in or out of the hole.

    2: Rotary System :

           The rotary system on a drilling rig

is the system that causes 

          the drill bit rotate at the bottom of well-bore. ... the Rotary Table

          the functionality on a top-drive  rig is handled by the top-drive.

          the Mouse-hole (Item 11) – used to connect single joints on

           a top-drive or rotary table rig.

      3: Circulating System :

            The circulation system on the rig

is the system that allows

         for circulation of the Drilling Fluid or Mud down through the 

         hollow drill string and up through the annular space between the 

         drill string and well-bore.

       4: Power System :

            The power system on a drilling rig

provides the power for

         the other main systems on the rig and other ancillary systems, 

         such as electrical systems, pumps, etc. ... In the detailed rig

         schematic , the power system is comprised of: the Fuel 

        Storage (Item 37) the Engines and Generators.

       5: Well Control System :

                 The Well Control System or the

Blowout Prevention 

           System on a drilling rig is the system that prevents the

           uncontrolled, catastrophic release of high-pressure fluids

           (oil, gas, or salt water) from subsurface formations.

           These uncontrolled releases of formation fluids are referred 

            to as Blowouts.

Thanks for watching.
