Introduction to Overshot
An overshot is a specialized tool used in the oil and gas drilling industry, as well as in other drilling operations such as mining and geothermal exploration. Its primary function is to retrieve lost or stuck drill pipes, collars, or other down - hole tools. The overshot typically consists of a body, a catching mechanism (such as slips or a grappling device), and a connection for attaching to the drill string. When lowered over the lost object, the catching mechanism engages with the outside of the object, allowing it to be pulled out of the wellbore.
Now, let's take a look at the top 10 overshot manufacturers in China.
