The utility model discloses can realize the pipe cluster and take off easily from top to bottom, improve cable strength, also convenient follow-up is salvaged, reduces and meets the ground operation risk when blocking.
Description
Technical field
The utility model relates to a kind of electromechanics and to give up device of escaping, and is applicable to Oil/gas Well cable transmission perforation, coordinates dynamo-electric releasing device to use, blow weakness by explosive charge energy, in liquid access to plant, promotes piston implement device and escapes up and down.
Background technology
Deep layer is drive in conventional gas and oil exploitation boldly, and unconventionaloil pool enters large-scale development, has both needed to ensure the pressure rating of wellhead sealing in cable transmission process, the tensile strength of the cable that also needs to ensure to go into the well.Present cable transmission perforation, must arrange weakness to cable before operation, once meet card, can be broken and realize departing from, but there is following problem: 1. card met by catch-basin, likely breaks from cable body, crisis flooring-safe by weakness; 2. horizontal well meet card, cable is no longer center condition, forced position can on move to cable body; 3. break from cable body, follow-up fishing intensity is large.
Publication number is CN2856382, publication date is a kind of Novel releasing gadget that the Chinese patent literature on January 10th, 2007 discloses that a kind of oil field well construction pipe string discharges locking, and this releasing device is made up of relieving mechanism, retaining mechanism (namely separating sealing mechanism), anchor mechanism, setting mechanism.The mechanism that this device is locked due to employing retaining mechanism and waterpower anchor fluke simultaneously has larger coupling mechanism force, ensure that the synchronism of deblocking simultaneously; In anchor fluke, adopt waterpower anchor fluke Structure anchor first, overcome slips easily broken de-, flimsy shortcoming, achieves bidirectional locking; Can be stressed separately owing to have employed split-type lock ring in solution sealing mechanism, guarantee that each lobe can untie separately the success rate that improve deblocking.This device can be widely used in oil field well construction pipe string release locking operation.
But with the prior art that above-mentioned patent document is representative, still there is following shortcoming in it: need to be escaped by ground artificial intervention when meeting card; The overall tensile strength of existing apparatus is inadequate, is not easy to escape; And cable body is easily pulled off.
Utility model content
The utility model is intended to for the defect existing for above-mentioned prior art and deficiency, and provide a kind of electromechanics to give up device of escaping, the utility model can realize pipe string and escape up and down, improves cable strength, also convenient follow-up salvaging, reduces Ground Operation risk when meeting card.
The utility model realizes by adopting following technical proposals:
A kind of electromechanics is given up device of escaping, it is characterized in that: comprise electric cap, detonating fuse, blast perforate bypass, blast weakness, escape and play pawl and sealing shroud of escaping, wherein: blast perforate bypass plays pawl one end and is connected with escaping, and the bullet pawl other end of escaping is connected with sealing shroud of escaping, and described detonating fuse is connected with electric cap, detonating fuse is installed in blast perforate bypass, and described blast weakness is fit into blast perforate bypass and embeds in detonating fuse.
Blast perforate bypass and escape plays between pawl, escaping plays pawl and escapes between sealing shroud and the weakness and explode between perforate bypass and be all equipped with O RunddichtringO of exploding.
Described blast weakness is that human factor is to a part design one place circumference stress concentrated position, detonating fuse detonation energy is utilized to be carried out blowing up or destroying by stress concentrated position, make UNICOM inside and outside releasing device, form the passage that place's liquid can flow, well liquid is by passage access to plant.
Compared with prior art, the beneficial effects of the utility model show:
The structure of escaping that the utility model adopts explosion type perforate, fluid power promotes piston, device bullet pawl reclaims, detonating fuse blast perforate feed liquor promotes piston, plays pawl and departs from spacing, device realizes pipe string and escapes up and down, improve cable strength, also convenient follow-up salvaging, reduce Ground Operation risk when meeting card.
Accompanying drawing explanation
Below in conjunction with specification drawings and specific embodiments, the utility model is described in further detail, wherein:
Fig. 1 is that electromechanics is given up structure drawing of device of escaping.
Mark in figure:
1: electric cap; 2: detonating fuse; 3: blast perforate bypass; 4: blast weakness; 5:O RunddichtringO; 6: bullet pawl of escaping; 7: sealing shroud of escaping.
Detailed description of the invention
The utility model discloses a kind of electromechanics to give up device of escaping, comprise electric cap, detonating fuse, blast perforate bypass, blast weakness, escape and play pawl and sealing shroud of escaping, its annexation is as follows: the first step, and all parts assemble O RunddichtringO; Second step, blast perforate bypass 3 being connected to escapes plays pawl 6; 3rd step, sealing shroud 7 of escaping is connected to escape and plays pawl 6; 4th step, detonating fuse 2 is connected with electric cap 1; 5th step, loads in blast perforate bypass 3 by the detonating fuse 2 assembling electric cap 1; 6th step, blast weakness 4 is screwed into blast perforate bypass 3, and embeds detonating fuse 2.
The structure of escaping that the utility model adopts explosion type perforate, fluid power promotes piston, device bullet pawl reclaims, detonating fuse blast perforate feed liquor promotes piston, plays pawl and departs from spacing, device realizes pipe string and escapes up and down, improve cable strength, also convenient follow-up salvaging, reduce Ground Operation risk when meeting card.
