Summary of the invention
The purpose of the utility model is the defective that exists to prior art; Provide a kind of oriented perforator to connect fastening devices fast; Simple in structure, can connect fast with position adjustable fixing fast; Shorten the perforation blind area length between the perforating gun simultaneously, increased effective cloth hole number of oriented perforator.
The utility model solves the technical scheme that its technical problem adopted: a kind of oriented perforator connects fastening devices fast, and its structure comprises orientation rifle head, orientation joint; Said orientation joint is the single joint of orientation, and said orientation rifle head connects oriented perforator through the single joint of orientation.
The single joint outer surface of said orientation rifle head and orientation is provided with trapezoidal external screw thread and fixing external screw thread, and the fixedly external screw thread of the single joint of said orientation rifle head and orientation all is with fixing hoop.
The trapezoidal external screw thread of the single joint of said orientation rifle head and orientation and fixedly the external surface between the external screw thread be provided with seal groove, also be provided with I shape Card trough and standard spanner duct at orientation rifle head and orientation list joint in addition.
Said orientation rifle head inner chamber offers priming device and connects internal thread, detonating fuse passage; Between priming device connection internal thread, detonating fuse passage, offer and set upright the colloid groove.
The single joint inner chamber of said orientation offers the detonating fuse centralizer body guiding groove and the detonating fuse passage of mutual perforation.
A kind of oriented perforator of the utility model connects fastening devices fast to be compared with prior art, has following beneficial effect:
The orientation rifle head that the utility model oriented perforator connects fastening devices fast is at former conventional pressure type or impacting type rifle head outside seal groove end fixedly screw thread and fixing hoop to be set; Being connected between perforating gun and the rifle head changes single joint into by original twin adapter and connects; Shortened the length of original transition joint; The single joint sealed at both ends of orientation groove end all is provided with fixedly external screw thread and fixing hoop, and the centre is provided with the I shape draw-in groove, and the inboard, upper end is provided with righting hole.Fixing of rifle head, single joint and perforating gun; Through the outside rollback of clip; Form reverse extruding with the perforating gun head precession, realize that the position adjustable fast self-locking is tight, realize that the unanimity and the blind holes of perforating gun direction of blind hole direction between the perforator is consistent with orientation pipe nipple direction of measurement.The utility model is simple in structure, can realize fixing quick connection of position adjustable between the oriented perforator, and shorten the length of perforation blind area between the perforating gun string, and blind area length only has 23mm, and single the effective cloth hole number of oriented perforation rifle has improved 4 holes.
