Description
API fishing tools Junk basket Catcher Sub
Junk sub is a special tool for catching the heavy iron fillings or grits which are too heavy to be completely circulated out of the hole. It is important for bottom-hole cleaning, ensuring the normal work of the bit and service life.
Because of the different interspace to the wellbore between the cup OD and the rim of cup, the fluid speed dropped promptly and form a vortex, meanwhile, the carry ability of fluid also dropped. So the heavey objects in the fluid will fall into the cup and carried out in the trip process.
- Designed and manufactured according to API spec 7-1.
- The Junk cup can clean sundries at the bottom of the well.
- It can improve the service life of drill bit.
- It operators can get quicker, cleaner scraping jobs.
