Downhole Fishing Tool LL Type Reverse Circulation Junk Basket
Product Overview
Model “LL” Reverse Circulating Junk Basket is designed to remove small pieces of junk such as bit cones, hand tools, slips, etc from the bottom of well. Its unique feature is utilizing the principle of reverse fluid circulation. Moreover, it can be used as a special coring tool.
Our TR 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.
