Description
Technical field
The utility model is related to a kind of perforator, more particularly to a kind of multi-stage pulse composite perforator device.
Background technology
It must be carried for composite perforator, hollow carrier used in oil, natural gas extraction both at home and abroad at present
A certain number of relief holes, the effect of relief hole are the high energy of moment generation after the pressure break efficacy-enhancing ingredient combustion made in perforator in perforating bullet
Gas is released outside the body of a gun in time, and detonation is changed by detonation to avoid pressure break medicine, at the same for prevent well killing fluid enter the body of a gun cause it is mute
Big gun is done over again, and must use special gasket on relief hole in operation.And due to it is difficult to ensure that sealing in practical operation
Pad is not fallen off, so it is difficult to ensure that operation quality and effect.
Invention content
The utility model provides one kind from open-cell multi-stage pulse composite perforator device, and it is caducous close both not need to setting appearance
Packing, and well killing fluid can be effectively prevented and enter the body of a gun, fundamentally avoid the generation of miso-fire rework problems.The multistage pulses are answered
It closes perforator and includes perforating gun, the firing mount of the tubulose containing energy, tube grain, perforating bullet and shallow bore hole bullet.The tubulose firing mount containing energy is arranged on
In perforating gun, and it is sleeved in tube grain.Containing that can be provided with perforating bullet in tubulose firing mount, the tail portion of perforating bullet sets one
Shallow bore hole bullet, perforating bullet and shallow bore hole projectile tail portion are equipped with round primacord slot, and primacord is equipped in primacord slot.It is right on the outer wall of the body of a gun
Blind hole should be provided at the position of perforating bullet and shallow bore hole bullet.When the utility model is used, this perforator is aligned in well
Perforation layer position, then detonating primer lead to and are ignited perforating bullets all in perforator and shallow bore hole bullet by primacord, in perforating bullet and shallow
Hole bounce it is quick-fried after, perforating bullet blows blind hole on the body of a gun and extends into stratum, and shallow bore hole bullet blasts hole at the blind hole of the body of a gun simultaneously.
After perforating bullet and shallow bore hole bullet are ignited, tube grain is ignited successively, and the firing mount containing energy and powder column form multiple-pulse effect, to stratum
Carry out perforation, pressure break effect.Since the blind hole position on the body of a gun is most weak, the impact force that shallow bore hole bullet is ignited is easy to blind hole hole
It opens, so that gunpowder detonation gas is made to be released in well rapidly, plays pressure release and prolong the effect of seam for perforation tunnel.
The utility model is simple in structure, reasonable design, and the wide open formula relief hole that existing product is changed on perforating gun is blind
Hole, and containing shallow bore hole bullet can be increased in tubulose firing mount, just fundamentally solve gasket during now with product operation in this way
It comes off, well killing fluid, which enters the phenomenon that body of a gun is so as to cause miso-fire to do over again, to be occurred.
Description of the drawings
It is attached that FIG. 1 is a schematic structural view of the utility model.

Specific embodiment
Perforating gun 1 in the utility model, the firing mount of the tubulose containing energy 2, tube grain 4, powder column 5 are that conventional material makes,
Perforating bullet 6 and primacord 8 are general equipment.With reference to the accompanying drawings, to being answered disclosed in the utility model from open-cell multistage pulses
Perforator is closed to be specifically described.
Embodiment：
The perforating gun 1 of the multi-stage pulse composite perforator device of the utility model is tubulose, and length is 1~4m, shown in attached drawing
It is wherein one section of cross-section structure, concrete structure is：The firing mount of the tubulose containing energy 2 is arranged in perforating gun 1, and be sleeved on pipe
In shape powder column 4, containing mounting hole can be equipped in tubulose firing mount 2, perforating bullet 6 and shallow bore hole bullet 7 are provided in mounting hole, shallow bore hole bullet 7 is set
It puts in the tail portion of perforating bullet, is corresponded on perforating gun 1 and blind hole 3 is equipped at the position of perforating bullet 6 and shallow bore hole bullet 7.Shallow bore hole bullet 7
Powder charge is equipped in shell case, the tail portion of shell case is equipped with primacord slot, and the tail portion of perforating bullet 6 also is provided with primacord slot, and leading for the two is quick-fried
Rope slot corresponds to installation, round primacord slot is formed, for installing primacord, that is to say, that perforating bullet 6 and shallow bore hole bullet 7 are primacord
It is clipped in the middle, primacord is made to be close to two bullets and is ignited simultaneously.The tail portion of perforating bullet 6 and shallow bore hole bullet 7 carries steel wire card hole, band in card hole
There is steel wire card 9, steel wire card 9 is fixedly connected with two bullets.
Perforator when in use, in well is directed at perforation layer position, then ignited by the composite perforator of the utility model
Detonator ignites perforating bullets all in perforator and shallow bore hole bullet via primacord, perforating bullet and shallow bore hole bounce it is quick-fried after, perforating bullet
Blind hole is blown on the body of a gun and extends into stratum, shallow bore hole bullet blasts hole at the blind hole of the body of a gun simultaneously.Perforating bullet and shallow bore hole bullet draw
After quick-fried, tube grain is ignited successively, and the tubulose firing mount containing energy and powder column form multiple-pulse effect, and perforation, pressure break are carried out to stratum
Effect.Since the blind hole position on the body of a gun is most weak, shallow bore hole bullet ignite impact force be easy to blind hole is wide open, to make gunpowder
Detonation gas is released in well rapidly, is played pressure release and is prolonged the effect of seam for perforation tunnel.
