摘要： A downhole tool incorporates a junk catcher with full body casing drift. It is made of an inner tubular member that conveys the hydraulic power or circulating fluid to rearward and outward facing jet nozzles for directly flushing downhole junks in front of the tool (if encountered) into a junk collecting barrel equipped with individual magnets to retain magnetically attractive metal junks. The barrel is made of high grade steel material with outer diameter matching the full drift of wellbore casing. The front, or the lower end of the outer body is addressed with tungsten carbide cutters to effectively handle metal junks in case of milling action is required. The back, or upper end of the barrel has return flow ports equipped with a filter screen to retain small, medium and large size junks while fluid is pumped through the tool.

摘要： An oil or gas well fishing tool (60) is provided. The downhole fishing tool (60) has a receptacle (61) that is open at one end. The tool also has deployment tool engaging means (62), located on the opposite end of the receptacle (61) to the one end. The tool further has a layer of an alloy (64) provided on the interior surface of the receptacle (61). The alloy is a eutectic alloy and/or a bismuth alloy. The tool further comprises heating means (65) to heat the alloy (64) so that it melts and can flow over any object received within the receptacle (61).

摘要： A method of freeing a pipe stuck in a subterranean well can include determining a location of a portion of the pipe stuck in the well, and penetrating and/or heating a sidewall of the pipe portion with a beam of light. A system for freeing a pipe stuck in a subterranean well can include a tool deployed into a portion of the pipe stuck in the well by a differential pressure from a wellbore to a formation penetrated by the wellbore. A beam of light emitted from the tool penetrates the pipe portion. Another method of freeing a pipe stuck in a subterranean well can include determining a location of a portion of the pipe which is biased against a wall of a wellbore by differential pressure, and directing a beam of light to the pipe portion.
