Description
Technical field
The utility model relates to the perforating gun that a kind of oil tube conveying gun perforation is used, and particularly relates to a kind of snap joint of perforating gun.
Background technology
In petroleum industry, perforation completion is present domestic and international most popular completion method.Perforation is described as " the going for goal shot " in the oil-gas exploration and development process, is the key link of formation testing operation, directly has influence on the oil gas well capacity.The perforation mode that generally adopts both at home and abroad at present has cable conveying gun perforation and oil tube conveying gun perforation.The cable conveying gun perforation can be accomplished individual layer or The Small Well section perforation; Perforation when oil tube conveying gun perforation can be accomplished long well section multilayer system, this mode also are the perforation modes that generally adopts both at home and abroad at present.
Sometimes need be when oil tube conveying gun perforation several even tens, up to a hundred perforating guns well operations under well head is connected in turn; Be screwed in and come together to realize and the connection between the perforating gun is a screw thread through male joint and female joint; From security needs; Can not use hydraulic tongs during connection, can only tighten with one one of pipe wrench with manual type.When needs connection tens, up to a hundred perforating guns, labour intensity is big, the activity duration is long, and because material control problem is prone to the thread gluing phenomenon, joint is generally no longer reused through after going into the well, and causes the waste of perforation equipment and the increase of cost.
Summary of the invention
The purpose of the utility model is to provide a kind of oil tube conveying gun perforation rifle snap joint that connects perforating gun more effectively, more quickly at well head.
For this reason, the technical scheme of the utility model is following:
The snap joint of a kind of oil tube conveying gun perforation rifle; Be made up of male joint and female joint, the outer end of said male joint and female joint is used for and the perforating gun screwed connection, and the end that said male joint connects female joint is formed with seal groove; On the male joint outer peripheral face in the seal groove outside, be formed with the claw of outside protrusion and the groove that caves inward; The lateral wall of groove is provided with a spring catch, is formed with annular slot in said female joint near the inner peripheral surface of the first end of public access, and the width of said annular slot and claw width adapt; On the female joint inwall, be formed with the claw groove that extends to said annular slot from port vertically; The shape of said claw groove and claw adapts, and is formed with a movable block in female joint near the port of male joint, on movable block, is formed with a screw fixed hole.
Preferably said claw is evenly equipped with 3 at the circumferencial direction of male joint, and the quantity of said claw groove is identical with claw quantity.
The quick coupling structure of the utility model is simple, easy to operate, safe and reliable, has improved operating efficiency greatly, reduces labour intensity.

The specific embodiment
Be elaborated below in conjunction with the structure of specific embodiment to the oil tube conveying gun perforation rifle snap joint of the utility model.
Referring to Fig. 1-Fig. 5, the oil tube conveying gun perforation rifle snap joint of the utility model is made up of male joint 1 and female joint 2, the outer end of male joint 1 and female joint 2 respectively with a perforating gun screwed connection.The end that male joint 1 connects female joint 2 is formed with seal groove 3; On the male joint outer peripheral face in seal groove 3 outsides, be formed with the claw 5 and the groove 6 that caves inward of outside protrusion; The lateral wall of groove is provided with a spring catch; Be formed with annular slot 7 in female joint 2 near the inner peripheral surface of male joint 1 one ends, the width of the width of annular slot 7 and claw 5 adapts.On the inwall of female joint 2, be formed with the claw groove 8 that extends to annular slot 7 from port vertically, claw groove 8 adapts with the shape of claw 5.In addition, be formed with a movable block 9 near the port of male joint 1, on movable block 9, be formed with a screw fixed hole 10, on movable block 9, be formed with a screw fixed hole 10 in female joint 2.
Referring to Fig. 2, in the present embodiment, claw 5 is evenly equipped with 3 at the circumferencial direction of male joint 1, and the quantity of the claw groove in the female joint is identical with claw quantity.
The method for using of this snap joint is following:
The male and female joint is connected with an oil tube conveying gun perforation rifle through the screw thread end separately, and this gets final product in indoor completion.Then the claw in the male joint is alignd with the upper clipping claw groove of female joint and male joint is inserted in the female joint, then male joint is rotated counterclockwise 60 ° with respect to female joint and puts in place, claw is got in the annular slot, screw is screwed into fixing hole gets final product.
When needing dismounting, screw is taken out from fixing hole, the relative female joint of male joint is turned clockwise 60 ° to put in place, and claw withdraws from the claw groove, pin and box sub is separated getting final product.
The snap joint of described oil tube conveying gun perforation rifle is done for the special metals steel, and pin and box sub and body of a gun link bracelet self connect and do not adopt screw thread, withstand voltage, sealing.
During oil tube conveying gun perforation, perforating gun connects the snap joint of employing perforating gun at well head, and snap joint is gone into the well with perforating gun and accomplished the perforation construction.Meet special circumstances, also easy and safety very when not accomplishing the perforation function and need dismantle only need be laid down hold-down screw at well head, and the relative female joint of male joint is turned clockwise 60 ° to put in place, and claw withdraws from the claw groove, pin and box sub is separated getting final product.
