摘要： Method and apparatus for providing tubing pack off for well operations and includes a pair of spaced apart stripper rubbers for packing off tubing in a tubular stripper assembly and which form an annular chamber between the tubular stripper assembly and the tubing. Ports are provided in the stripper assembly for use in flowing coolant into such chamber to prevent thermal damage to the stripper rubbers. A thermal pack off means is provided to cooperate with the above described stripper assembly to form a composite stripper assembly particularly useful during shut in periods.

摘要： "FRANGIBLE CUP THERMAL PACKER" A subsurface well bore completion assembly for a cased well is disclosed. The assembly includes thermal cup packers which may be set at a subsurface location along the well above a hot fluid injection zone. The assembly is run into the well on a tubing string and, at the desired depth, the assembly is converted to operating condition where the packers and slips are set. The apparatus may be reassembled to running condition for withdrawal from the well or the packers may be drilled-over to permit washover in the wall.

摘要： "CONCENTRIC STEAMING STRING DOWNHOLE APPARATUS" A downhole concentric tubing string is disclosed for use in distributing steam, or other hot fluids, to separated subsurface formations along a well bore. The apparatus includes elements for deflecting the steam from one string into the annulus of a cased well for injection through openings into the formation, elements for conducting the steam in another of the concentric string to a second set of openings for injection into another portion of the formation, and elements of isolating and separating the two separate injection intervals.
