Answer 1

What type of drill bit have moving parts Drilling machine will helps us to make holes. Drilling machine is a combination handle and drill bit ! which means whole set up, → The Tool which penetrates into the surbace is called drill bit proper selection of drill bit is necessary at differ ditte applications. handle Drill bit & - 2 basic Types of bits Roller cone bits (moving parts) fixed bits (Stationary parts) Roller Cone bits will have the cone type bits like shown in figure below, will rotates separately leads to digging, Fixed bits Fixed bits have no moring parts and hole will create due to percussion and rotation.

Tricone bit - po like shown in figure This bit have cone like shape I OG parts) Nooo rock cones will rotale in creation of hole. different directions (moving → so leads to * Diamond bit i will dont have like moving parts so it is not a bit which will have moving part in it * Polycrystalline diamond compact and blade bit also did not have moving parts init 20) Usage of fluids in drilling :- * To avoide friction ble bit and surface usually blends are gases and muds are water and oil * so when drilling a well, an overb to balance Condition exists. if the pressure on the fluid in the subsurface rockis. greeer than the pressure of the drilling mud- True. endot build & general aim is to create deviated hole - Kick off point So moving vertically some distance build angle and getting deviation, Tip of vertical is called lack off deviak angle is - build angle 7 after deviaton from there need vertical hole, so end of angle is end of build - whips tock is a wedge which will place in well to stop the bit.
