Drill Rig Parts Fishing Tool Junk Sub for Oilfield

Certification: API
Type: Petroleum Drilling Tool & Accessory
Usage: Offshore Oil and Gas Field Exploitation Machinery
Product Structure
As the outer diameter of the external bowl is bigger, the space between the external bowl and the well hole is reduced guiding most of the fluid through the cup. The mandrel diameter at the cup mouth is bigger with larger annular space. Thus, the fluid forms a swirl at the cup mouth as the fluid flows down through the cup with a sudden reduction in capacity at the bottom. Through this working principle, some heavy objects will drop in the cup and be fished out, ensuring that the well-bore bottom is cleaned.
