Q15－18
Most of us use oil in some way, and it is difficult to
imagine the modern world without oil. But oil is not easy to find and get out
of the earth as it is trapped deep down in the ground. We must first study the
rocks carefully. When we think that the rocks in a certain place may contain
oil, we load a metal tower in the location either on the land or under sea.
This metal tower is called a derrick. The derrick is equipped with oil drilling
machinery. The machine will cut a narrow hole down into the ground. Meanwhile a
steel pipe is pushed down to stop the sides from falling and to keep out water.
At last, if we have judged correctly, the oil would rush up the pipe with great
force. This is basically how an oil well is set up. Oil, as we can see, is
obtained more easily than coal. For coal, very often we must dig it from a mine
and have it sent up to the ground surface. But for oil, it rushes up a pipe. If
an oil well is made near the middle of the oil field, then natural gas can be
obtained. In parts of the world, such gas is often sent through pipes to
distant towns and cities, so that it can be used like coal gas in houses and
factories
Question 15 Why is it difficult to find oil?
Question 16 What is a derrick?
Question 17 Why does the speaker say that oil is obtained
more easily than coal?
Question 18 According to the speaker, what can be obtained
when an oil well is made near the middle of the oil field?
