Description
Editorial Note for 2010100721 There is one page of description Screw-down Packer The innovation applies to oil and gas industry and intends for well inter vals isolation for the wells with one or few formations for production. The screw-down packer consists of mandrel with packing elements and protective o-rings on it, upper support and lower support constructed by way of body which connected with mandrel by breaking pins. Upper support developed by the way of C-ring and fixed on mandrel with screws. The body has restrain ers which prevent barring. The quantity of breaking pins depends on axial stress on mandrel through tubing. The tool consists of: 1- Seating; 2 - lower support developed by way of body and connected with mandrel 10 by breaking pin 3. Screws 4 prevent the body 2 from barring. Packing elements 6 with rings 5 locate on the mandrel be tween lower support and upper support which developed by way of C ring 8. The C-ring 8 fixed between screws 7 and 9, screwed together on mandrel 10. Seating 1 locates on body 2 and can move along the mandrel. The tool operates the following way: The packer connects with tubing by seating 1 and mandrel 10 and runs into the well hole. When packer achieves total depth the axial stress should be apply. Then the axial stress cut the breaking pins 3 between mandrel 10 and body 2. The mandrel 10 moves down acting on packing elements. Packing ele ments extend and isolate the tubular annulus.
