摘要： A device is provided for cementing a casing in a well bore. The device includes, on the well head side, a shutter disposed within the casing that controls opening and closing of at least one cementing aperture. The at least one cementing aperture makes an interior of the casing communicate with an annular space situated between an external face of the casing and an internal wall of the well. The device also includes, on the well bottom side, a packer having two expandable liners mounted along the external face of the casing and at least one communication passage between an exterior of the first external liner and the annular volume. The at least one communication passage is situated on the packer side orientated towards the well bottom.

摘要： A method of patching a well or a pipe by hydroforming a tubular metal patch. A tool provided with a pair of inflatable packers is inserted inside the patch. The pair of inflatable packers are axially spaced apart from each other by a distance that is substantially equal to the length of the patch. The tool is positioned inside the patch so that the packers are in register with the end portions of the patch. The assembly of the tool and the patch is axially inserted inside the well or the pipe, and positioned in register with the zone for patching. The packers are inflated to a high pressure, sufficient for radially expanding the end portions of the patch and pressing them in a leak-tight manner against the wall of the well or the pipe. The packers are subsequently deflated and the tool is withdrawn. The method is applicable to the oil industry.

摘要： The invention relates to device for controlling an inflatable tool used to treat a well or pipeline. The device, which is inserted between the outlet of a fluid supply pipe and the tool, comprises: a chamber communicating with the exterior through a tube and with the tool via a pipeline; and a piston mounted in said chamber, which, under the force of a spring, normally occupies a first position in which it seals the outlet of the pipe, the aforementioned tube then communicating with the pipeline. The pipeline is provided with at least one spring-loaded check valve which allows the passage of the pressurised fluid from the chamber to the tool when the pressure upstream of the valve exceeds a predetermined threshold value, which prevents the passage of the fluid in the opposite direction.

摘要： According to the method, a cylindrical tube (1) is inserted into the well or the pipe (C) that is to be lined, after which part of the tube is radially expanded using an inflatable bladder (2) so that the wall of the tube is pressed against that of the well or of the pipe (C). According to the invention, this expansion is achieved by moving the already-expanded bladder axially and continuously along inside the tube (1) over a travel corresponding to the length of the tube or of the region of tube that is to be expanded. Fields of water or oil production.

摘要： The device is a sleeve that is radially expandable under the action of an inflation fluid so as to press the sleeve hermetically against a wall. The sleeve includes firstly a pair of cylindrical membranes having walls that are flexible and elastic, the membranes being engaged coaxially one inside the other, comprising an inner membrane for being subjected internally to the pressure of the inflation fluid, and an outer membrane for being pressed against the wall of the pipe or the well in order to provide sealing, and secondly, interposed between said membranes, at least one very dense annular fiber structure made up of a multitude of fine and long fibers having high mechanical strength that interconnect said end members and that are wound helically around the inner membrane, said winding being such that the density of the fibers diminishes from each end towards the central portion.
