How Does an Oil Drill Work?
Setup An oil drill is set up over a hole where an oil trap, or reservoir, of oil has been discovered. There is a scaffolding called a derrick built above ground with a wire and pulley system extending down from the top of it. This pulley system is used to pull the drill out of the hole when necessary. A rod and turn table are attached to the end of the pulley system, and piping is attached to the turntable. The drill bit is last and is attached to the end of the pipe. Drilling If there is no power supply, a generator is used to start and run the engine. The engine is the motor that causes the turntable to turn. Once on, the turntable will turn the drill bit that will eat away at the earth. The drill will go down deep and then be brought up to add more piping. The piping allows the drill to be pushed further down into the ground, creating a deeper hole as it goes. Once a drill bit has been used for a while, it will be brought up and replaced with a new sharper one. This is done more oft
