Downhole Tools Reverse Circulation Junk Basket / Junk Catcher
Product Descrption
Reverse circulation junk basket is used to catch all kinds of small
junk objects such as cones,cutters,hand tools from bottom well.
During drilling operation, it produces a local reverse circulation
of fluid at well core so as to effect a complete recovery of junk
in the junk basket.
The special reverse flow feature creates a vortex back through the centre of thebasket encouraging all loose and dislodged junk to pass into the barrel through thecatcher. Junk embedded in the bottom formation canbe core milled, the mill cuttingsand the core itself being removed by the tool.
Product Operation
Our 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” core has been cut.
Stop rotation and circulation and pull the tool from the hole.
