Abstract
The utility model provides an efficiency-enhancing perforating gun for oil gas wells. The utility model comprises a gun body 1 and a bullet rack 2. The improvement of the utility model is that a decompression hole on the pipe wall of the gun body is a blind hole having a rubber stopper 3, and a metallic framework 4 can be arranged in the rubber stopper 3; as the decompression hole of the efficiency-enhancing perforating gun for oil gas wells is the blind hole, water can not be penetrated into the gun; the rubber stopper on the blind hole can enhance the pressure bearing performance of the blind hole, and thus, water can not be penetrated into the gun under the conditions of high temperature and high pressure. Meanwhile, the decompression hole can normally decompress during explosion.
Description
The utility model relates to a kind of perforating oil gas well rifle, particularly oil gas well synergy perforating gun.
Known oil gas well synergy perforating gun comprises the body of a gun and firing mount, and the relief hole on the body of a gun tube wall is a through hole, has rubber seal plug or metal plug on the relief hole.Because the oil gas downhole temperature is higher, pressure is bigger, and the relief hole of the perforating gun of this structure infiltration easily enters in the rifle, and perforating gun can not be detonated, and causes fried rifle when perhaps detonating, and the body of a gun is stuck in the well, brings great difficulty to construction.
The purpose of this utility model is to provide a kind of oil gas well synergy perforating gun, to overcome the deficiency of known technology.
The utility model is achieved in that a kind of oil gas well synergy perforating gun, and it comprises the body of a gun 1 and firing mount 2, and its improvements are that the relief hole on the body of a gun tube wall is a blind hole, has rubber stopper 3 on the blind hole.
The utility model oil gas well synergy perforating gun can be to have metallic framework 4 in the rubber stopper 3.
The oil gas well synergy perforating gun that the utility model provides, relief hole is a blind hole, can not seep water enters in the rifle, rubber stopper on the blind hole can improve the withstand voltage properties of blind hole, under the bigger situation of the higher and pressure of temperature, do not seep water, simultaneously when detonating, normally pressure release of relief hole.
Fig. 1: the sketch of a kind of form of structure of the utility model oil gas and synergy perforating gun.
The partial enlarged drawing of Fig. 2: Fig. 1.
The utility model is described in further detail in conjunction with the embodiments with reference to accompanying drawing.
Embodiment 1, and Fig. 1 and Fig. 2 have provided a kind of concrete structure mode of the utility model oil gas well synergy perforating gun.As shown in the figure, it comprises the body of a gun 1 and firing mount 2, and the relief hole on the body of a gun tube wall is a blind hole, has rubber stopper 3 on the blind hole.Has metallic framework 4 in the rubber stopper 3.Relief hole is a blind hole, and can not seep water enters in the rifle, and the rubber stopper on the blind hole can improve the withstand voltage properties of blind hole, the resistance to pressure of the installation of the favourable rubber stopper of metallic framework in the rubber stopper and raising blind hole.The oil gas well synergy perforating gun of this structure can guarantee not seep water under the situation that temperature is higher and pressure is bigger, normally pressure release of relief hole when detonating simultaneously.
