Superdeep Drilling

Our drillers have completed the stage of sinking a superdeep well. The drilling of a superdeep drilling well is of tremendous scientific interest because the majority of problems that interest researchers are still at the stage of hypothesis. It is very important to know the composition and physical state of interior spheres of the Earth, what physical and chemical transformations of matter are taking place there, or how these rocks move to cause the drift of continents and especially – the origin of the Earth.

Superdeep drilling is a very labour-consuming process. And all the more in arctic conditions. Each pipe coming to the drillers from the factory is subjected to electroscopic testing.

To reach the planned depth is a job so serious and so complex that the drillers must calculate literally every step. The geologists working on the superdeep well are using the latest methods of geological and geophysical research. They have obtained data which tend to change our concepts of the “lower storeys” of the Earth’s crust.

Student: I am a petroleum engineer and I am interested in the construction of a subsurface centrifugal pump.

Teacher: All right. You may put questions to me and I’ll try to answer them.

Student: Well, what can you say about the dimensions of such a pump?

Teacher: As far as I know, the cross-sectional dimensions of a motor are restricted by the diameter of the casing string but the length of it is quite considerable.

Student: As far as I can judge the speed of this motor must also be considerable.

Teacher: Yes, as it was mentioned in special literature the speed of subsurface pump motors is about 3000 rpm.

Student: Well, if the length of a subsurface centrifugal pump is considerable (about 7 meters) then it is not convenient for transportation?

Teacher: Right you are, for transportation the motor and pump which are quite long are placed on special racks keeping them fixed and protecting them from bending under gravity.

Student: Thank you very much for the information you have given to me.

21. Английский юмор:

The professor, who was famous for being absent-minded, returned home and rang at the door.

The ring was answered by a new maid. The girl looked at him inquiringly.

“Um-ah- is Professor Thompson at home?” he asked, naming himself.

“No, sir,” the maid replied, “but he is expected any moment now.”

The professor turned away, the girl closed the door. Then the poor man sat down on the steps to wait for himself.

At the Top

- A telegram from George, dear.

- Well, did he pass the examination this time?

- No, but he is almost at the top of the list of those who failed.

Father: Aren’t you ashamed to be at the bottom in a class of twenty-eight boys?

Willie: Oh, that’s not so bad.

Father: What do you mean, not so bad?

Willie: Suppose there were fifty boys.
