Reverse Circulation Junk Basket - China

price: contact company for price

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.

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.

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

the tool. It is also converted into a Fishing Magnet by

replacing the catchers with a Bowen Magnet Insert.
