[0023] In order to make the purpose, technical solution and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the attached drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0024] The following describes the specific implementation of the present utility model in detail with reference to specific embodiments.

[0025] As Figures 1-5 shown, it is a structural diagram of a gas explosion bottle provided by an embodiment of the present utility model, including: a gas explosion bottle body 1, and a cavity for filling gas is formed inside the gas explosion bottle body 1;

[0026] A weakening groove 13 is provided on the wall surface of the gas explosion bottle body 1, and the weakening groove 13 is used to guide the blasting direction of the gas explosion bottle body 1 so that the energy generated by the blasting propagates along the target direction.

[0027] In the embodiment of the present utility model, preferably, the gas explosion bottle can be applied to the seismic source device used in microseismic detection in oil and gas wells, and is used in cooperation with a signal receiving device to facilitate receiving the signal of the shock wave generated after the gas explosion bottle explodes, so as to detect the conditions in the oil and gas wells. The gas explosion bottle includes a gas explosion bottle body 1 and the gas filled in the internal cavity of the gas explosion bottle body 1. A combustion improver can also be added to the gas filled in the internal cavity of the gas explosion bottle body 1 to facilitate the detonation of the gas explosion bottle. A weakening groove 13 is provided on the wall surface of the gas explosion bottle. By using the weakening groove 13 to guide the blasting direction of the gas explosion bottle body 1 during blasting, the energy generated by the blasting can be concentrated and propagated along the target direction, so that the signal receiver used in cooperation can receive the shock wave with concentrated energy propagating downward to the ground and then returning to be detected by the signal receiver, thereby detecting the position of the wellbore, making the detection accuracy higher. Compared with the prior art in which the scattered fragments generated after detonation affect the detection effect, the energy generated by the gas explosion bottle is more concentrated and has a certain guiding property after being guided by the weakening groove 13, so as to improve the detection accuracy.

[0028] In one example of the utility model, the utility model provides a gas explosion bottle body 1 with a cavity, and gas is filled in the gas explosion bottle body 1, and a weakening groove 13 is provided on the wall surface of the gas explosion bottle body 1, by detonating the gas explosion bottle body 1 and guiding the direction of the gas explosion bottle body 1 by the weakening groove 13 of the bottle body, while guiding the energy of the gas explosion inside the gas explosion bottle body 1 to propagate along the target direction, to the target position in the target direction, and then return to be received to detect the specific position of the target position in the target direction, the energy of the explosion is concentrated by the guidance of the weakening groove 13, and the energy generated by the explosion propagates along the target direction, so that the detected direction is more accurate and with high precision.

[0029] like Figures 1-5 As shown, as a preferred embodiment of the utility model, the gas explosion bottle is cylindrical, a cylindrical bottle mouth 11 is arranged on the top of the gas explosion bottle, the inner diameter of the bottle mouth is smaller than the inner diameter of the bottle body, and the bottom 12 of the gas explosion bottle is arc-shaped to disperse the pressure of the gas on the bottom 12 of the gas explosion bottle.

[0030] In an embodiment of the utility model, preferably, the gas explosion bottle can be a cylindrical hollow structure with a certain length, and the outer diameter of the cylindrical bottle mouth 11 is smaller than the outer diameter of the gas explosion bottle body 1, and the cylindrical bottle mouth can be used to connect with the gas valve to facilitate the filling of the gas explosion bottle with gas and combustion aid. The connection between the cylindrical bottle mouth 11 and the bottle body can be an arc-shaped surface, which is similar to the arc-shaped bottom 12 in order to disperse the pressure of the internal gas on the bottom 12 of the gas explosion bottle to prevent the gas explosion bottle from self-explosion during transportation.

[0031] like Figures 1-2 As shown, as a preferred embodiment of the present utility model, the weakening groove 13 is a closed-loop groove 131 arranged on the side wall of the gas explosion bottle body 1, which is used to make the gas explosion bottle body 1 explode in the radial direction.

[0032] In an embodiment of the utility model, preferably, the weakening groove 13 can be a closed-loop groove 131 arranged on the side wall of the cylindrical bottle body. When the gas explosion bottle body 1 is detonated, the gas explosion bottle explodes radially according to the shape of the closed-loop groove 131 on the side wall. At this time, when installing the gas explosion bottle, the position of the closed-loop groove 131 can be kept consistent with the target direction of detection, so that the energy after the explosion can be concentrated and propagated.

[0033] like Figures 1-2 As shown, as a preferred embodiment of the utility model, the weakening groove 13 is set as a rectangular closed ring, and the long side of the rectangular closed ring is parallel to the axial direction of the gas explosion bottle body 1, and the groove depth of the long side of the weakening groove 13 is less than the groove depth of the short side.

[0034] In the embodiment of the present utility model, preferably, the closed-loop groove 131 can be a rectangular closed loop. The long side of the rectangular closed loop is parallel to the axial direction of the air-burst bottle, and the short side is parallel to the radial direction of the body of the air-burst bottle and the groove depth of the short side parallel to the radial direction is deeper. When the air-burst bottle body 1 explodes, the short side, that is, the radial direction, will explode first to guide the propagation direction of the energy when the air-burst bottle explodes. When exploding, it will explode according to the wall thickness of the air-burst bottle body 1. The short side in the radial direction of the weakening groove 13 will explode first and then extend to the long side to achieve axial explosion.

[0035] As Figures 3-5 shown, as another preferred embodiment of the present utility model, the weakening groove 13 includes a first annular groove 132 arranged circumferentially along the air-burst bottle body 1 for enabling the air-burst bottle body 1 to explode axially.

[0036] In the embodiment of the present utility model, preferably, the weakening groove 13 can include a first annular groove 132 arranged circumferentially along the air-burst bottle body 1. When the air-burst bottle body 1 is detonated, the air-burst bottle will explode axially according to the shape of the first annular groove 132 arranged circumferentially. At that time, the bottom 12 of the air-burst bottle will separate from the air-burst bottle body 1. At this time, when installing the air-burst bottle, the orientation of the bottom 12 of the air-burst bottle can be kept consistent with the detected target direction so that the energy generated by the explosion can be concentratedly propagated.

[0037] As Figures 3-5 shown, as a preferred embodiment of the present utility model, the groove depth of the weakening groove 13 is kept uniform.

[0038] In the embodiment of the present utility model, preferably, the groove depth of the first annular groove 132 arranged circumferentially on the air-burst bottle body 1 is kept uniform everywhere, so that the air-burst bottle body 1 will be stretched and exploded along the groove width of the first annular groove 132 during explosion, and the groove width direction is the same as the axial direction of the air-burst bottle.

[0039] As Figures 3-5 shown, as a preferred embodiment of the present utility model, the weakening groove 13 further includes a second annular groove 133 arranged circumferentially along the air-burst bottle body 1, and the second annular groove 133 and the first annular groove 132 are respectively arranged on the inner and outer sides of the air-burst bottle.

[0040] In the embodiment of the present utility model, preferably, the weakening groove 13 can further include a second annular groove 133 arranged circumferentially along the inner wall surface of the air-burst bottle, and is arranged on the inner and outer sides of the air-burst bottle separately from the first annular groove 132. The second annular groove 133 can be used to locate the position where the bottom 12 of the air-burst bottle body 1 falls off during explosion, and also enables the energy generated by the explosion to be concentratedly propagated.

[0041] As Figures 3-5As shown, as a preferred embodiment of the present utility model, the first annular groove 132 is located outside the air explosion bottle body 1, the second annular groove 133 is located inside the air explosion bottle body 1, and the width of the first annular groove 132 is greater than the width of the second annular groove 133. The second annular groove 133 is located at the middle position in the axial direction of the first annular groove 132.

[0042] In the embodiment of the present utility model, preferably, the width of the second annular groove 133 is smaller than the width of the first annular groove 132, and the second annular groove 133 is located at the middle position in the axial direction of the first annular groove 132. When the air explosion bottle body 1 explodes along the axial direction, it will preferentially explode and break at the second annular groove 133, causing the bottom 12 to fall off. When the first annular groove 132 and the second annular groove 133 are separately provided inside and outside and the second annular groove 133 is also located at the middle position in the axial direction of the first annular groove 132, the wall thickness at the second annular groove 133 will be the thinnest when the air explosion bottle explodes, and it will preferentially explode from here to achieve energy concentration during explosion.

[0043] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
