7. Find the words which correspond to the given definitions:
An assembly of sheaves, mounted on beams at the top of the derrick, over which the drilling line is reeved.
A method of determining optimum weight on bit and overall bit performance by tying down the brake and measuring the time required to drill off certain weight intervals as the drill stem decompresses.
All members in the assembly used for rotary drilling from the swivel to the bit, including the kelly, drill pipe and tool joints, drill collars, stabilizers, and various specialty items.
The heavy steel member, three-, four-, six-, or eight-sided, suspended from the swivel through the rotary table and connected to the topmost joint of drill pipe to turn the drill stem as the rotary table turns. It has a bored passageway that permits fluid to be circulated into the drill stem and up the annulus, or vice versa.
An automatic machine designed to work without needing someone to operate it for each part of the process.
8. Agree or disagree with the following statements:
A sharp bit, used in the right formation and properly run, will drill faster than a worn bit improperly run or used in the wrong kind of rocks.
Many rigs are equipped with drilling rate recorders, which allow quick comparison of penetration rates.
Comparing measurements provides an accurate estimate of bit performance.
Drill-off technique makes use of the fact that the drill stem is an elastic medium like a spring, the length of which varies with its tension.
By maintaining constant weight on bit and hydraulic effort, drill-off tests can be useful for finding optimum rotary speed.
9. Answer the questions:
What can variations in the drilling rate indicate?
What is the usual basis for comparing bit performance?
How can a driller determine the drilling rate without the help oа automatic devices?
What is a commonly used method of measuring rate of penetration to determine optimum weight on bit and rotary speed?
How does it work?
What can drill-off tests be used for?
Why are drill-off tests repeated several times?
10. Explain why it is crucially important to observe variations in the drilling rate and how the rate of penetration can be measured to determine optimum weight on bit and rotary speed.
