cement mixture
Can you please help me with the underlined parts? Thank you.
Oil wells are cemented to prevent the water from layers permeable to water, by the use of water and cement mixture under pressure in the space between protection pipes and rocks. At first, oil is bailed from the deepest oil field, and when it is exhausted/bailed, the lower part of the oil well is filled with cement and oil bailing from the upper layer begins. Passing of oil is ensured by explosive which drills/blows up the protection pipe and cement shield/shell. Detonation of the explosive is made/done/carried out electrically.

- Again I'm not sure about the ternminology 'bailed' and 'bailing'.

Thank you Alan.
I am not quite sure how this works. Why do explosives blow up the protection pipe?
The flow of oil is ensured by explosives which blows up the protection pipe and cement shell.

They drill a hole which goes down to the deepest levels that they know contain oil and, at first, bypass some deposits at levels nearer the surface. They also need to put a cement case around the outer shell of the pipes to stop water filtering in at some levels. Th production pipe going down the well is a concentric tube arrangement with several pipes fitting over one another.
