Abstract
The utility model provides a packer can be got and bore. Relates to the technical field of oil field downhole tools. At feed liquor hole downside, the deblocking pin joint seat cover is passed through to the center tube inboard, and seat cover downside is opened on the center tube has one section slot hole, and seat cover extends out one section tongue piece to the slot hole in, and the tongue piece extends to the center tube excircle position, and tongue piece outside ditch inslot installs the jump ring, and it has the annular to advance cover lower part hole to open, advances the cover and passes through sealing washer, seat pin joint connection upper joint. The utility model discloses following beneficial effect has: through setting up the jump ring that is located the packing box of center tube inboard and advancing the annular of cover and make up the setting, utilize to drop into soluble ball and promote the packing box and cut the deblocking pin deblocking, can also cut the deblocking pin with the milling tool when the deblocking fails, the cut volume is little, and the deblocking is reliable.
Description
The technical field is as follows:
the utility model belongs to the technical field of the oil field instrument technique in the pit and specifically relates to a packer can be taken and bored.
Background art:
the zonal injection packer used at present consists of an upper joint, a central pipe, a lower joint, a rubber sleeve and a setting mechanism, and due to the complexity of water quality of injection water in some oil fields, an underground tool is seriously corroded and scaled in the long-term water injection production process, so that the structure of the underground tool mainly comprising the packer loses the action function, the packer cannot be unsealed, the underground packer cannot be unsealed by adopting major workover equipment, the underground packer cannot be unsealed, the construction period is long, the cost is high, and the production operation is seriously influenced.
The utility model has the following contents:
in order to solve the problem of difficulty in treatment when the packer corrodes, scales, unable deblocking, the utility model provides a packer can be taken and bored.
The technical scheme of the utility model is that: the utility model provides a packer can be taken and bored, including the top connection, the lower clutch, the center tube, the packing element, the retaining ring, advance the cover, the feed liquor hole of opening on piston and the center tube, above-mentioned structure is the prior art of packer, at feed liquor hole downside, the deblocking pin joint seat cover is passed through to the center tube inboard, seat cover downside, it has one section slot hole to open on the center tube, seat cover extends out one section tongue piece to the slot hole in, the tongue piece extends to center tube excircle position, install the jump ring in the tongue piece outside slot, it has the annular to advance cover lower part hole to open, it passes through the sealing washer to advance the cover, it connects to sit the pin joint.
The clamp spring is in a compressed state, and the annular groove of the pushing sleeve is located at the position of the clamp spring when the rubber sleeve is set.
An arc-shaped spring plate is vulcanized and fixed in the rubber cylinder.
The utility model discloses following beneficial effect has: the jump ring through setting up the sitting cover that is located the center tube inboard carries out the combination to sit and seals, utilizes to drop into soluble ball and promotes the sitting cover and cut the deblocking pin deblocking, can also cut the deblocking pin with the milling tool when the deblocking fails, and the cut volume is little, and the deblocking is reliable.
Description of the drawings:
fig. 1 is a schematic structural diagram of the present invention.
In the figure, 1-an upper joint, 2-a lower joint, 3-a central pipe, 4-a rubber cylinder, 5-a check ring, 6-a pushing sleeve, 7-a piston, 8-a liquid inlet hole, 9-a deblocking pin, 10-a setting sleeve, 11-a long hole, 12-an annular groove, 13-a tongue block, 14-a snap spring, 15-a setting pin and 16-an arc spring plate.
The specific implementation mode is as follows:
the present invention will be further explained with reference to the accompanying drawings:
shown by figure 1, a desirable packer that can bore, including top connection 1, lower clutch 2, center tube 3, packing element 4, retaining ring 5, impel cover 6, feed liquor hole 8 that opens out on piston 7 and the center tube 3, above-mentioned structure is the prior art of packer, at 8 downside of feed liquor hole, 3 insides of center tube connect the seat envelope cover 10 through deblocking pin 9, seat envelope cover 10 downside, it has one section slot hole 11 to open on the center tube 3, seat envelope cover 10 extends out one section tongue piece 13 to slot hole 11, tongue piece 13 extends to 3 excircle positions of center tube, 13 outside ditch inslot install jump ring 14, impel 6 lower part bores of cover to open there is annular 12, impel cover 6 to pass through the sealing washer, seat seal pin 15 connects top connection 1.
The clamp spring 14 is in a compressed state, and the annular groove 12 of the pushing sleeve 6 is located at the position of the clamp spring 14 when the rubber barrel 4 is set.
An arc-shaped spring plate 16 is vulcanized and fixed in the rubber cylinder 4.
When setting, beat in the tubular column, liquid promotes piston 7 and propulsion cover 6 and goes down, propulsion cover 6 goes down to jump ring 14 position, jump ring 14 outwards opens and gets into annular 12, propulsion cover 6 axial fixity, the setting is accomplished, when the deblocking, drop into soluble ball and seal on setting cover 10, beat in the tubular column, promote setting cover 10 and cut deblocking pin 9, setting cover 10 axial freedom, arc spring board 16 stretches out, packing element 4 contracts, promote to advance and move the deblocking on cover 6, when the deblocking, it will set up sealing cover 10 to go into the milling tool, deblocking pin 9 grinding can be deblocking to go down, the packer after the deblocking can not disperse, lift the tubular column and propose the well head with the packer.
The jump ring through setting up the sitting cover that is located the center tube inboard carries out the combination to sit and seals, utilizes to drop into soluble ball and promotes the sitting cover and cut the deblocking pin deblocking, can also cut the deblocking pin with the milling tool when the deblocking fails, and the cut volume is little, and the deblocking is reliable.
