What is this device? Where is it used? What are the features?

Isn’t this a submersible screw pump, with the motor driving the pulley and gear reduction mechanism?

Judging from its appearance, it seems to be a submersible screw pump used in oil drilling and extraction.

Isn’t oil extraction done using pump jacks? I don’t see any screw pumps either

I used the image search feature on this photo, and it showed that it’s an oil pumping pump, haha. I’m not familiar with the equipment used in upstream oil operations; I’m waiting for everyone’s answers.
