Patent ID: 8240373

Claim:
A junk basket tool for use with a tubing string for retrieving debris from an oil or gas well, the junk basket tool comprising: a tubular mandrel having an upper end and a lower end, the upper end being connectable to the tubing string; a nose on the lower end of the mandrel, the nose having at least one fluid outlet; wherein the mandrel and the nose form a continuous fluid flow passage therethrough; and a tubular strainer basket slidably supported for axial movement on the mandrel between an open position and a closed position, the strainer basket having a closed upper end and an open lower end and forming a debris collection chamber therebetween with fluid ports; wherein the strainer basket, the mandrel, and the nose are relatively configured so that in the open position debris-carrying well fluids can enter the open lower end of the strainer basket and fluid can exit the debris collection chamber through the fluid ports allowing the debris to collect in the debris collection chamber and so that in the closed position the open lower end of the strainer basket is occluded by the nose, whereby the strained debris can be withdrawn from the well bore; and wherein the fluid flow passage is configured to allow fluid to be passed through from the tubing string through the mandrel and out the at least one fluid outlet of the nose while the tubing string is advanced.
