Abstract
The utility model provides an oil pipe transfer perforation electric igniting device, which comprises a metal casing(1), and the utility model is characterized in that a battery(2) is arranged inside the metal casing(1). One electrode of the battery(2) is connected with an electrode of an electric detonator, and the other electrode is connected with a conductive tube(3). A guide sleeve(4) is arranged inside the casing(1). A conductive bar(5) is arranged inside the guide sleeve(4). The lower end of the conductive bar(5) is provided with an elastic conductive body(6). The lower end of the conductive tube(3) is provided with a power off cavity(7). When the elastic conductive body(6) arranged at the lower end of the conductive bar(5) is entry into the conductive tube(3), the conductive tube(3) is electrically communicated with the casing(1). When the conductive bar(5) is positioned on a lower stopping point, the elastic conductive body(6) is released from the conductive tube(3) and entry into the power off cavity(7), the circuit is opened. The utility model has the advantages of safety and reliability.
Description
One, technical field:
The utility model relates to a kind of oil tube conveying gun perforation electric initiator that is used for the oilfield perforation.
Two, background technology:
At present, known oil pipe is carried initiator, it has an igniter cap and a flame detonator, by percussion cap, make igniter cap light flame cap sensitive perforation, the weak point of this structure be in the ignition process in case does not ignite successfully, still have the possibility of ignition during afterwards oil pipe tubing string, its security reliability is poor.
Three, summary of the invention:
The purpose of this utility model is to provide a kind of oil tube conveying gun perforation electric initiator, to overcome the deficiency of known technology.
The utility model is achieved in that a kind of oil tube conveying gun perforation electric initiator, it has metal shell (1), its special character is to have battery (2) in the housing (1), an electrode of battery (2) is connected with the electrode of electric cap, another electrode is connected with contact tube (3), in housing (1), has fairlead (4), has conducting rod (5) in the fairlead (4), the lower end of conducting rod (5) has elastic electric conductor (6), the lower end of contact tube (3) has outage chamber (7), when the elastic electric conductor (6) of conducting rod (5) lower end enters in the contact tube (3), contact tube (3) and housing (1) energising, when conducting rod (5) when being positioned at lower dead center, elastic electric conductor (6) breaks away from contact tube (3) and enters outage chamber (7) circuit and disconnect.
Oil tube conveying gun perforation electric initiator of the present utility model can be to have retainer (8) on the conducting rod (5).
The oil tube conveying gun perforation electric initiator that the utility model provides has safe and reliable advantage.
Four, description of drawings:
Fig. 1: a kind of structural representation of the present utility model.
Five, the specific embodiment:
The utility model is described in further detail in conjunction with the specific embodiment with reference to accompanying drawing.
The specific embodiment 1, accompanying drawing has provided a kind of concrete structure of the utility model, consult Fig. 1, it has metal shell (1), has battery (2) in the housing (1), an electrode of battery (2) is connected with the electrode of electric cap, another electrode is connected with contact tube (3), in housing (1), has fairlead (4), has conducting rod (5) in the fairlead (4), the lower end of conducting rod (5) has elastic electric conductor (6), the lower end of contact tube (3) has outage chamber (7), when the elastic electric conductor (6) of conducting rod (5) lower end enters in the contact tube (3), and contact tube (3) and housing (1) energising, when conducting rod (5) when being positioned at lower dead center, elastic electric conductor (6) breaks away from contact tube (3) and enters outage chamber (7) circuit and disconnect.On conducting rod (5), has retainer (8).When caber or pressure detonated, the descending elastic electric conductor of conducting rod (5) (6) entered in the contact tube (3), and circuit is connected, electric cap is ignited, in case do not ignite successfully, conducting rod (5) comes downwards to lower dead center, elastic electric conductor (6) breaks away from contact tube (3) and enters outage chamber (7), and circuit disconnects.Retainer (8) is locked in lower dead center to conducting rod (5), and no longer including ignition later on may.Has safe and reliable advantage.
Claims (2)
1, a kind of oil tube conveying gun perforation electric initiator, it has metal shell (1) and it is characterized in that having battery (2) in the housing (1), an electrode of battery (2) is connected with the electrode of electric cap, another electrode is connected with contact tube (3), in housing (1), has fairlead (4), has conducting rod (5) in the fairlead (4), the lower end of conducting rod (5) has elastic electric conductor (6), the lower end of contact tube (3) has outage chamber (7), when the elastic electric conductor (6) of conducting rod (5) lower end enters in the contact tube (3), contact tube (3) and housing (1) energising, when conducting rod (5) when being positioned at lower dead center, elastic electric conductor (6) breaks away from contact tube (3) and enters outage chamber (7) circuit and disconnect.
2, oil tube conveying gun perforation electric initiator according to claim 1 is characterized in that having retainer (8) on the conducting rod (5).
