I went to Daqing oil city to visit tourism with my grandfather and colleagues in their unit.
How beautiful Daqing is! There are white clouds in the blue sky, green grassland, pink peach blossom, plain white pear flower, golden Chrysanthemum under the high derrick. The first scenic spot we visited was the "underground palace". Listening to the commentator's introduction, I learned about the process of oil formation. Oil was deposited in sponge shaped stone holes after the death of sea creatures. It took tens of millions of years to form oil. I also know how oil is extracted from the ground. When oil is extracted, a lot of water is injected into the ground to generate pressure. In this way, oil is pumped together with water. 90% of it is water and only 10% is oil.
Then we visited the iron man Memorial Hall. Before we visited the iron man memorial hall, I still thought, what is the iron man memorial hall? Is it made of iron? I entered the iron man Memorial Hall curiously, and only after the introduction of the interpreter did I know that "Iron Man" is Wang Jinxi, a hero of oil production. He is like a man of "iron", who desperately exploits oil for the country. He has a famous saying: "it is better to live 20 years less than to win the big oil field", so we call him "Iron Man".
By visiting Daqing oil city, I learned not only the knowledge of oil, but also the heroic deeds of "Iron Man" Wang Jinxi. This is a happy and meaningful tour.
