Reverse Circulation Junk Basket Fishing Tool for Drilling Fluids

Product Description

Product Description

Reverse circulating junk basket is a fishing tool which use the drilling fluids partly reverse in the bottom hole, to latch small junk in the basket. It is used for fishing all types of small junk, objects in well bores, such as bit cones, cutting blades and hand tools, etc.

Boban Reverse Circulation Junk Basket is made up to the bottom of the fishing string and lowered to a point within several feet from the bottom of the hole. Begin circulation to wash the hole. Stop circulation and drop the steel ball. (When the steel ball is dropped into the valve seat, circulation fluid travels outward and downward through the inner passage of the barrel and out through the vents in the lower end. The fluid is then deflected to the center of the tool and up through the return holes in the upper end of the barrel. This reverse fluid circulation carries the junk into the barrel above the junk catcher.) Begin circulation again, slowly rotating while lowering the tool until a 10-inch core has been cut. Stop rotation and circulation and pull the tool from the hole.
