Product Description

20 Years Supplier Fishing Tools Junk Sub Fishing Sub for Oilfield

Product Description:
 (Fishing Cup) is normally used to catch and remove junks that are too heavy to be circulated preventing them from settling at the bottom of the well-bore. Typical junks are shivers and fallen objects such as carbide tooth, drill bit and bearings which are too heavy to be removed from the well- hole through conventional fluid circulation. Junk Sub's main function is to keep well bottom clean to increase bit service life, reduce and prevent drill bit from unexpected damage.

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.

Features:
1. Designed and manufactured according to API spec 7-1.
2. The Junk cup can clean sundries at the bottom of the well.
3. It can improve the service life of drill bit.
4. It operators can get quicker, cleaner scraping jobs.
