      1. Miscellaneous

annular space (annulus)

затрубное (межтрубное) пространство

The space between two concentric objects, such as between the wellbore and casing or between casing and tubing, where fluid can flow.

cuttings

буровой шлам

Small pieces of rock that break away from the formation due to the action of the drilling bit.

deviated drilling

наклонно-направленное бурение

The intentional deviation of a wellbore from the path it would naturally take.

kick

выброс

An undesired flow of reservoir fluids into the wellbore during drilling operations.

perforation

перфорация

The communication tunnel created through the casing into the reservoir formation, through which oil or gas is produced. The most common method uses perforating guns equipped with explosive charges.

pit

амбар

A large tank that holds drilling fluid and other fluids on the rig.

to kill

глушить (скважину)

To stop a well from flowing. Kill procedures typically involve removing reservoir fluids out of the wellbore or pumping high density mud into the wellbore, or both.

Ex. 2. Answer the questions and check how well you have understood the definitions.

      1. What is produced due to the action of the drill bit?

      2. What lubricates the drill bit?

      3. Where is drilling fluid stored?

      4. What kind of pipe is used to produce reservoir fuids?

      5. Is kick a favourable or unfavourable phenomenon?

      6. What shape do derricks have?

      7. What is the synonym for slurry?

      8. Can fluid flow between casing and tubing?

      9. Which of the pipes has the largest diameter?

      10. What is the name of the machine that drills wells?

      11. What kind of pipes does the string include?

      12. What helps to prevent blowouts?

      13. In what manner does the drill bit work?

      14. What creates tunnels through casing into the rock formation?
