Problems solved by technology
[0003] The main purpose of the present invention is to provide a detonating cord-free perforating gun for perforating oil and gas wells, which adopts a detonating cord-free design, and the entire system adopts plug-in and contact connections. The direct contact between the pin and the detonator acts as a detonator trigger, which detonates the detonator and ejects the perforating projectile. At the same time, the detonator also directly contacts the conductive rod to conduct electricity. The conductive rod transmits the current to the next pin through the conductive sheet, detonating the next section of perforation The detonator in the gun solves the technical problems of the existing perforating gun with complex structure, poor perforation effect and potential safety hazards in the detonating cord

The invention discloses a detonating-cord-free perforating gun for oil and gas well perforation, and relates to the technical field of perforating gun manufacturing. The technical problems that an existing perforating gun is complex in structure and poor in perforation effect, and a detonating cord has potential safety hazards are solved. The detonating-cord-free perforating gun for oil and gas well perforation comprises a contact pin (1), a partition plate joint (2), a gun barrel (3), a detonator (4), a perforating bullet rack (5) and a conductive rod (6). The detonating-cord-free perforatinggun for oil and gas well perforation can be used for exploding and jetting to open strata in oil well development. According to the detonating-cord-free perforating gun for oil and gas well perforation, by adopting the detonating-cord-free and joint-free design, the structure is simple, and the detonating-cord-free perforating gun is safer and more efficient.
Description
technical field [0001] The invention relates to the technical field of perforating gun manufacturing, in particular to a detonating cord-free perforating gun for perforating oil and gas wells. Background technique [0002] The perforating gun is a combination of equipment and accessories used for perforating oil and gas wells. Multiple perforating guns are connected in series and then lowered into the oil well to explode and shoot out the formation. , when using the perforating gun, the user needs to open the perforating gun, connect the lead wire, add perforating charges, detonating cord, detonator and connect the selective firing switch. The production efficiency of the construction, and the pyrotechnic wire as a detonating cord has potential safety hazards. Contents of the invention [0003] The main purpose of the present invention is to provide a detonating cord-free perforating gun for perforating oil and gas wells, which adopts a detonating cord-free design, and th...
