Drilling


A high mineral consisting of the main material called barium sulfate, which is in the process must be mixed with a powder to increase density and prevent an oil or gas from the explosion.
The term - a term in the drilling:

1. Bit: The cutter (making holes) of drilling machine used to drill holes.
2. Blow-out: A way out of oil or gas, which generally happens to (suddenly) from a drilling well drilling throughout the region.
3. Blow-out preventer: High pressure Valves operate normally installed dipuncak hydrolysis of drilling a well casing to prevent a blow-out (burst / explosion) of oil or gas.
4. Casing: A layer of steel that is used to prevent a widening of the wells, for a discharge that is not needed, and to provide tools to control the well pressure and production of oil or gas.
5. Cement: an additional part of the space between the casing and the drill hole wall with mortar. When the cement is hardened it will be the case in the drill hole and prevent leakage in a strata (levels) that have been drilled. Transmitter strings (the drill into the ground) it is cemented to the surface of the ground.
6. Choke: nipple (where the oil or melincirnya end of the bore holes) that can be moved, for example in the path of a well that is used to control the flow of oil. Sometimes called "Bean" (beans).
7. Circulating fluid: air circulation equipment, fluids and gases in a drill hole that continues berputas during the drilling process in progress.
8. Conductor: The first strings of casing of the drill hole, also called the string surface. This section must be secured with the process of Cementing.
9. Core:
10. Crown block: assembly or file a binding equipment at the top of the oil rig, which is a wire line as
11. Derrick: steel structure used to support the drill pipe and other equipment that must be lifted and lowered well as the process of drilling is in progress.
12. Doghouse: a place of refuge in the floor that is used for drilling rigs and other hands (people).
13. Dogleg: a bending edge in a well either in purpose or accidental.
14. Downhole: a term that refers to a piece of drilling equipment that has its own function.
15. Draw works: raise forklift to handle the drilling pipe, casing, and tubing.
16. Drill Collar: extra heavy pipe, some placed directly above the drilling bit. Concentrate to serve part of the heavy strings near the base (base) and to use the necessary pressure on bits, thereby preventing buckling of the string.
17. Drill pipe: steel pipe used to carry and play equipment in a well drilling and for the circulation (control) of the drilling fluid.
18. Drill pipe elevator: a clamp that buttoned, aims to raise the gear in a drilling tool and drill to pull the strings from the hole.
19. Drill stem testing: how to make the test method of preparation of an oil bearing formation, formation fluid is allowed to flow to the drill pipe in a short time.
20. Drill string: field drill pipe and drill collars that screw together, at the end of the bit had been in the screw.
21. Drilling fluid: the fluid that usually consists of clay that imprisons the water, which is used to drill wells.
22. Drilling rigs: the structure and complete machinery needed to drill a well, the term is also commonly used to describe a mobile platform that is used for investigation of offshore drilling.
23. Dynamic positioning: the working methods in offshore drilling in place floating structures using marine based computer assistance in overseeing the work supporting equipment (motor).
