Abstract
The utility model discloses a composite perforating gun with an inner blind hole, a via hole and a pressure release hole. The device consists of a gun body, a gun carrier and a pressure release hole. A sunken inner blind hole is arranged at the symmetrical position of the pressure release hole on the inner wall of the gun body. The pressure release hole is a penetrable step hole arranged on the gun body. A steel frame sealing device with a rubber packing is arranged in the step hole. The utility model has the advantages of high blasting height, deep perforation and rapid pressure release.
Description
Technical field
The utility model belongs to the petroleum machinery technical field, especially relates to blind hole composite perforation gun in a kind of through hole pressure release cellular type.
Background technology
In the use practice process in oil field, the use of perforating gun is more extensive, in order to pursue darker wearing deeply, the often equipped bigger perforating bullet of specification of perforating gun that diameter is less, for example equipped 102 type perforating bullets of 89 type perforating guns; The equipped 127 type perforating bullets of 102 type perforating guns etc., though this assembling mode is than the perforating gun of standard configuration, such as 89 rifles adorn 89 bullets, 102 rifles are adorned 102 bullets, wear dark raising some, but the height of burst of perforating bullet in the less rifle of diameter that specification is bigger is significantly less than same perforating bullet and is fitted in the height of burst in the bigger perforating gun of diameter, and the height of burst of perforating bullet in rifle is to influence perforating bullet to wear dark important parameter, therefore, in order to make perforating bullet can realize darker wearing deeply, just must improve the interior height of burst of rifle of perforating bullet.
Summary of the invention
The purpose of this utility model be to improve the deficiency of prior art and provide that a kind of height of burst height, perforation are dark, blind hole composite perforation gun in the pressure release through hole pressure release rapidly cellular type.
The purpose of this utility model is achieved in that blind hole composite perforation gun in the through hole pressure release cellular type, is made up of rifle body, firing mount and relief hole, is characterized in being provided with on relief hole symmetric position on the rifle body inwall the interior blind hole of depression.
In order further to realize the utility model purpose, can be that described relief hole is that the rifle body is provided with penetrating stepped hole, the sealing of steel frame rubber gasket is assemblied in the stepped hole.
Compared with the prior art the utility model has following distinguishing feature and good effect: the utility model adopts the interior blind hole that is provided with depression on relief hole symmetric position on the rifle body inwall, improves the interior height of burst of rifle of perforating bullet like this; Compare with the outer blind hole perforating gun of identical configuration, the height of burst can improve 7～8mm in the rifle of perforating bullet, and the perforator cement target of blind hole structure is worn the dark raising 10%～15% of comparing with the outer blind hole structure perforator of same configuration in adopting; Relief hole is that the rifle body is provided with penetrating stepped hole, and the sealing of steel frame rubber gasket is assemblied in the stepped hole, and the through hole pressure release makes that the pressure release of compound gunpowder is rapid more, even, the safety that has improved composite perforation gun.
Description of drawings
Below in conjunction with drawings and Examples the utility model is described in further detail.
Fig. 1 is a kind of structural representation of the present utility model.
Fig. 2 is an another kind of structural representation of the present utility model.
The specific embodiment
Embodiment 1, blind hole composite perforation gun in the through hole pressure release cellular type, with reference to Fig. 1, be in rifle body 1, to be provided with firing mount 2, perforating bullet 7 is positioned on the firing mount 2, be provided with relief hole 3 on the rifle body 1 of placing perforating bullet 7 correspondence positions, be provided with the interior blind hole 4 of depression on relief hole 3 symmetric positions on rifle body 1 inwall, this constitutes a kind of structure of the present utility model.
Embodiment 2, and blind hole composite perforation gun in the through hole pressure release cellular type with reference to Fig. 2, is on the basis of embodiment 1, and relief hole 3 is that rifle body 1 is provided with penetrating stepped hole 5, and 6 sealings of steel frame rubber gasket are assemblied in the stepped hole 5, and other and embodiment 1 are identical.
Claims (2)
