为什么要钻井? 我们知道石油是埋藏在地里面的,离地面深浅不一,怎么样将这些石油自地里取出来,这在石油工业中是很重要的一个工作。什么地方有石油,怎样找法,这是石油探勘方面的工作,可是要确实证明他们的工作,也需要另一种工作来完成的。这种工作就是“钻井”。钻井的简单意思,就是将地面上钻一个洞下去,与挖吃水井一样,不过钻取石油的井,一般地说都很深,井口很小,以现在的记录来说,最深可达6公里多,井径最大有17(3/4)英吋。所以非人工所可完成。
Why drilling? We know that oil is buried in the ground, from the surface of different depths, how to remove the oil from the ground, which in the oil industry is a very important task. Where there is oil, how to find ways, it is oil exploration work, but to prove their work, but also need another job to complete. This kind of work is “drilling.” The simple meaning of drilling is to drill a hole in the ground down to the same extent as a digging well. However, drilling oil wells is generally very deep and the wellhead is very small. With current records, it can reach a depth of up to 6 km More, the maximum diameter of 17 (3/4) inches. So non-human can be done.
