Operational retrievable packer with mechanical landing type "M-1X"

One of the most common methods of repair and insulation works is the isolation of channels of annular flows by injection of cement material under pressure, using drilled packers. Thus, the operational retrievable packer with a mechanically fit type "M1-X" can be used: - in production, pumping, for isolation of individual zones as a lower packer in a tandem assembly, for all types of service work; - to disconnect the casing in vertical, directional and horizontal wells in the area of its installation; - to protect production columns from exposure to the injected fluid, as well as from pressure increase during technological operations on the impact on the bottomhole formation zone during the operation of injection and production wells, etc. "M-1X" - a packer with a mechanical fit by compressing or stretching the sealing and fixing elements of the packer. A retrievable packer allowing the tubing to be in a stretched, compressed or neutral position. FEATURES AND BENEFITS: * Three assembly options are possible for different differential pressures: standard pressure of 7.500 psi (517 atm.), With a large bore through hole of the packer and differential pressure of 10,000 psi (690 atm.). * The tubing can be left stretched, compressed or neutral. * Holds the differential pressure above and below the packer (in the tube and annulus). * Landing right-handed rotation, the release of right-handed rotation. * The landing and releasing mechanism of the castle type (with the J-figure groove), i.e. the mechanism allows the packer to be freed from the tubing load and, when using additional devices, replace the tubing without disrupting and lifting the packer. * Internal bypass channel that allows you to quickly balance the pressure after the packer breakdown. * The location of the seals below the upper wedges allows washing of the settled sludge before the packer is released through the bypass valve. * Converted to mechanical bridge plug when using augmented valve. * Easy landing procedure and secure release mechanism twisted right. * The design provides for the mechanism of emergency removal of the packer by rotating it to the right, which prevents the pipe cuffs during emergency operations with the packer. APPLICATION AREA: * It can be used in mining, forcing, for isolating individual zones as a lower packer in a tandem assembly, with all types of service work. * To uncouple the casing in vertical, directional and horizontal wells in the area of its installation. * To protect production columns from the effects of the injected fluid, as well as from pressure increase during technological operations on the impact on the bottomhole formation zone during the operation of injection and production wells. * Allow you to search for places of leakage of the production string, conducting interval interval impact on the bottomhole formation zone of the chemical. reagents; interval injection of fluid into injection wells to maintain reservoir pressure (water, polymer solutions, etc.). * Allow to perform repair work when using the detaching device M-2 and a deaf plug in gas and oil wells without plugging them. * The use of various modifications of the packer M1-X allows for the repair of wells without their lifting to the surface and repeatedly testing for tightness: * After work in the well, the rise of the packer to the surface is carried out without overflow. * The use of packers M1-X when pumping aggressive chemical reagents into the well allows you to protect the production string from corrosion and significantly reduce the cost of injecting neutralizing corrosion inhibitor fluids, * When using a layout of 2 packers, it is possible to exploit, perform formation treatments, and regulate the injection in 2 different production horizons opened in one well. * The use of full-pass packers M1-X can significantly reduce the cost of overhauls in injection and gas wells when using installations “Coiled tubing”, since in this case, the time and cost of works when performing cattle without raising the operating elevator will be several times lower (the possibility of flushing the propannt after hydraulic fracturing) Various designs of packers M1-X allow using them: - without lift columns, - as bridge plugs, - as a basis (holding tool) for other equipment (valve-cutters, suspension filters). * Possibility of application for hydraulic fracturing and other service work. * An additional method of planting by stretching allows the use of a packer at shallow depths (using a shank)
