Product pictures of reverse circulation junk basket


Description: The reverse circulation junk basket is used to retrieve all types of small junk objects in well bores. This tool's unique principle of reverse circulation ensures complete recovery of all junk and eliminates misruns. A drain through the tool also eliminates the possibility of pulling a wet string even though the inner barrel is plugged by the core. In addition, it may be converted into an effective fishing magnet and still retain the reverse circulation feature. Features: A single junk catcher is used in each assembly. A lifting sub is provided for ease of handling which includes a storage space for the steel ball used in the operation of the tool. It is converted into a fishing magnet by replacing the catcher with the Bowen magnet insert.

Alternate Shoes available are the Type B and Type C. The Type B shoe is similar in design to Type A but dressed with Itcoloy. The Type C is flat bottomed and dressed with Itcoloy.

reverse circulation junk basket Specification: During operation, with the steel ball dropped into the valve seat, fluid flows through the inner passage of the barrel and out the vents in its lower end. The fluid is directed outward and downward and deflected toward the center. Fluid flows in a continuous stream to the center of the tool and up through return ports in the upper end of the barrel. All junk is thus carried into the barrel above the junk catcher.

 

 

The Full-Flow reverse circulation junk basket is similar to the standard Reverse Circulation Junk Basket and is also used to retrieve small junk objects in well bores. The difference is that the Full-Flow type has a unique valve assembly which allows circulation through the center to keep out shale or debris while running in the hole. A drain through the tool eliminates the possibility of pulling a wet string even though the inner barrel is plugged by the core. 

reverse circulation junk basket Operation:

During operation, the ball is dropped to the valve seat. Pump pressure then causes pins to shear which opens the reverse circulation cavity to circulation. Fluid flows through the inner passage of the barrel, out the vents in its lower end, outward and downward deflected toward the center in a continuous stream, and up through return ports in the upper end of the barrel. All junk is thus carried into the barrel above the junk catchers.

Features:Alternate Shoes available are the Type B and Type C. The Type B shoe is similar in design to Type A but dressed with Itcoloy. The Type C is flat bottomed and dressed with Itcoloy.

Specification:Two Junk Catchers are used in each assembly. A Lifting Sub is provided for ease of handling which includes a storage space for the steel ball used in the operation of the tool. It is also converted into a Fishing Magnet by replacing the catchers with a Bowen Magnet Insert.

 

 

The Bowen - Itco Junk Basket is a rugged junk fishing device, using either a Mill Shoe or Flat Bottom Type Shoe in conjunction with two sets of free revolving finger type Catchers.

Features: The catchers are of rivetless construction. They may be easily redressed on the job, eliminating the necessity of returning them to the shop for replacement. The upper catcher is designed to effectively break the core that is cut by the shoe. The fingers extend only halfway to the center.


The lower catcher has alternately short and long fingers which extend almost to the center of the tool to effectively collect and retain odd pieces of junk or cores.

This Junk Basket may be easily converted to a fishing magnet by replacing the catchers with a Bowen magnet insert. Alternate Mill Shoes available are Type B and Type C. The Type B is similar to Type A in design but with ltcoloy dressing. The Type C is flat bottomed and dressed with Itcoloy.

Specification: Operation of the Itco Junk Basket is simple, requiring only slow rotation and circulating fluid, to retrieve junk, cores or both simultaneously.
