APPARATUS AND METHOD FOR REMOVING DEBRIS FROM A WELL

摘要

An apparatus and method for retrieving debris from the well bore of an oil or gas well. The apparatus comprises a junk basket 36 with a flow passage 34 that allows fluid to be jetted out end 24 of the tool 10 while the tubing string is advanced to stir up the debris in the well fluids and facilitate capture of the debris in the strainer basket 36. Importantly, upon encountering a plug of sand or other debris in the well bore, fluid flow through the tool can be increased to work on the plug until it breaks apart. Advancement of the tubing string can be halted and resumed, as needed, in combination with control of the fluid flow through the tool until the junk basket 36 is fu or the targeted debris is collected, whereupon the junk basket 36 is withdrawn. The junk basket 36 may be deployed on coiled tubing or string of drill pipe.
