The technical scheme that the utility model adopts is: mechanical type transposition valve comprises top connection, upper seal bore, piston tube, tube connector, packing element top connection, packing element, packing element core pipe, packing element lower contact, spacing ring, shearing ring, shear pin, outer barrel assembly, switching-over head, spring pressure ring, spring, spring spacing ring, stop screw, joint ring, Glais ring, sealing-plug and lower contact.It is characterized in that: there is the oil pipe internal thread upper end of top connection; There is external screw thread the lower end of top connection, and the lower end of the top connection upper seal bore that is threaded has exterior seal ring between top connection and the upper seal bore; There is horizontal screw the upper end of top connection; Screw is fixed on upper seal bore in the top connection, and a piston tube is arranged in the top connection lower end, between piston tube and the top connection inner seal ring is arranged; Be slidingly matched between the lower end outer wall of piston tube and the upper seal bore inwall, the lower end of piston tube is connected with tube connector.Between piston tube and the upper seal bore sealing ring is arranged; On the upper seal bore wall, balance pipe is arranged, liquid can get into the plunger shaft of being made up of top connection, sealing drum and piston tube through balance pipe;
There is external screw thread lower end at upper seal bore, the packing element top connection that is threaded of the lower end of upper seal bore; The lower end of packing element top connection connects packing element core pipe; Outer suit packing element of packing element core pipe and packing element lower contact; Packing element core pipe lower end connects spacing ring with tubing round thread; Spacing ring upper end outer wall is equipped with key, and the effect of key is each part of upper end and each part locking radial of the lower end that is connected with the packing element lower contact that spacing ring is connected.There is external screw thread outer barrel assembly upper end, and outer barrel assembly upper end and packing element lower contact are by being threaded, and crosswise fixed has hold-down screw in packing element lower contact lower end, and the inner of hold-down screw is in the groove of outer barrel assembly outer wall; Outer barrel assembly upper end crosswise fixed has shear pin, and shear pin is fixed together outer barrel assembly and shearing ring.The position of shearing ring is in the bottom of spacing ring; Between packing element lower contact and packing element core pipe, middle sealing ring is arranged; Between packing element lower contact and the outer barrel assembly lower seal is arranged; Four shallow inside grooves and four dark inside grooves are arranged in the outer barrel assembly, and four shallow inside grooves and four dark inside grooves are spaced and symmetry; The switching-over head of the lower end screw shackle shape of tube connector; There is a spring pressure ring spacing ring lower end, and the spring pressure ring is set with spring outward, and the spring spacing ring of spring lower end is fixed by the stop screw that is contained on the outer barrel assembly.A joint ring is arranged in outer barrel assembly, and joint ring and outer barrel assembly are slidingly matched, and the lower end of spring pressure ring and joint ring upper end are fixed together; Two groups of Glais rings are arranged on the outer wall of joint ring; Two groups of holes that are parallel to each other are arranged on the outer barrel assembly; Last extraction or the implanted layer between packing element and the following supporting packer pointed in last one group of hole, and next group hole gets into the following extraction or the implanted layer of supporting packer lower end down through the bridge-type mechanism with sealing-plug, lower contact composition.It is to be sealed by the joint ring and the Glais ring that are contained in the outer barrel assembly that one group of hole is arranged in two groups of holes that are parallel to each other all the time.A sealing-plug is arranged in outer barrel assembly, and sealing-plug and outer barrel assembly are slidingly matched; There is external screw thread the lower end of outer barrel assembly, the lower contact that is threaded of the lower end of outer barrel assembly.When the last one group of hole of pointing to the upper strata of joint ring and Glais ring sealing, extraction liquid will be entered in the oil pipe by extraction through bridge-type mechanism by lower floor, or injection liquid enters into down implanted layer by oil pipe through bridge-type mechanism.
Adopt elasticity to divide claw to be connected between piston tube and the tube connector; Adopt elasticity to divide claw to be connected between spring pressure ring and the joint ring,, except that frictional force, can not form big reaction torque guaranteeing axially effectively to effectively reduce difficulty of processing under the situation of transmitted load, make commutate more reliable.
When being used with the fluid pressure type packer according to the operating principle of lower packet; Can selecting oneself to set earlier still respectively, lower packet sets earlier; But should being in to close, the joint ring when setting lower packet earlier in the outer barrel assembly closes one group of position of opening; Hydraulic pressure just can be delivered to lower packet like this, and should be equipped with corresponding kit.Because the packing element on this transposition valve sets for the mechanical compress mode, the lower end needs a fulcrum when setting, so bottom and fluid pressure type packer be when being used, and does not advise that lower packer props up the shaft bottom and oneself set earlier then.
The operating principle of summary mechanical type transposition valve.Be connected on above position, circle, oil reservoir perforation top, top during work.Cooperating slip-type packer pipe string with the utility model below is its operating principle of example explanation.
The pipe string that is connected to setting ball seat, slip-type packer, connection oil pipe and the utility model is from bottom to top gone into well on request; When the bottom slip-type packer is positioned at upper and lower two-layer centre, the utility model and is positioned at above position, circle, oil reservoir perforation top, top; Set the bottom slip-type packer on request; Continue to transfer tubing string then; Pressurization sets mechanical type transposition valve, and its packing element is supported on the casing wall under the effect of ballast, realizes the not perforated interval more than the circle, packing element top perforation top and the perforated interval of bottom are effectively isolated.Install behind the well head and can implement to inject or extraction, inject or extraction layer position, only need add hydraulic pressure from oil sets annular space if need change to change from set unlatching layer, whenever boost-step-down once, just realize once transposition, so repeatedly.
Open and close transpositions: if be in out closed position down when going into well, then output liquid in upper strata is through the annular space entering outer barrel assembly between the utility model cartridge and bottom anchor packer, then from the oil pipe output; Then enter into the annular space between lower packet through outer barrel assembly otherwise inject liquid, enter into implanted layer again from oil pipe.
If be in open position under the shangguan when going into well, then lower floor's output liquid enters into the utility model below the anchor packer of bottom, turns to outer barrel assembly at the sealing-plug place through lower contact, walks around sealed tube and enters into the above oil pipe output that gets into of sealing-plug.Enter into the utility model otherwise inject liquid through oil pipe, the place is hampered at sealing-plug, walks around sealing-plug through outer barrel assembly and enters into through lower contact and enter into down implanted layer below the lower packet again.
The beneficial effect of the utility model: the utility model mechanical type transposition valve; The bottom connects slip-type packer or tubing anchor; The hydraulic-set packer of connecting band self-locking also is used; Can be implemented in repeatedly alternate water injection, the wheel of accomplishing the different layers position under the sleeve pipe hydraulic control and adopt, adopt with respect to conventional alternate water injection, wheel, it is easy, particularly good to the big oil-water well compliance of interlayer pressure difference to have constructing operation.
