Detailed Description
The invention provides a device for processing a choke tube sand card cable in a pressurized perforating operation, which has compact structure and strong operability, and can rapidly process the problem of choke tube sand card cable in the pressurized perforating operation, thereby providing assistance for improving the maintenance efficiency of the accidents.
As shown in fig. 1, fig. 1 shows a schematic diagram of an apparatus for handling choke tube sand card cables in a pressurized perforating operation provided by the present invention for handling choke tube sand card cable accidents at a wellhead. For example, the wellhead is provided with a wellhead valve 2, a three-wing blowout preventer 3, a lubricator 4 and other devices, and the device 1 for treating the choke tube sand-blocking cable in the pressurized perforation operation provided by the invention only needs to be lifted through the control head 6 of the crane 5, the choke tube and the multistage choke tube jacket are opened step by step from top to bottom, and then dirt attached to the cable is cleaned. Further as shown in fig. 2, fig. 2 is a schematic structural view of an apparatus for treating choke tube sand card cables in a pressurized perforating operation. The device for processing the choke sand-blocked cable in the pressurized perforating operation comprises a choke clamp 11 (used for establishing fixed connection with the choke 7), a choke sleeve clamp 12 (used for establishing fixed connection with the choke sleeve 8), a nut 13 for the choke sleeve clamp, a nut 14 for the choke sleeve clamp and a screw rod 15. As shown in fig. 3, the choke collar 11 is formed by two choke tube quick fasteners of identical shape; two choke clamp fastening holes 111 and a choke clamp screw connecting hole 112 are formed in each choke tube quick fixing piece; a choke clamp fastening bolt is arranged at the position of the choke clamp fastening hole 111, and a close connection relation is established between the choke clamp and the choke tube by tightening the choke clamp fastening bolt (wherein reference numeral 113 in fig. 3 is the position of the choke tube bound by the choke clamp); preferably, the choke tube clamp fastening bolt is also matched with a matched choke tube jacket clamp fastening nut, so that a worker can conveniently screw the choke tube clamp fastening bolt. And a choke collar rubber gasket is further arranged on the choke collar at the position in contact with the choke, and the choke collar rubber gasket plays a role in increasing friction force. A choke collar nut is installed in the choke collar lead screw connection hole 112, and a fixed connection relationship between the choke collar and one end of the lead screw is established through the choke collar nut.
As shown in fig. 4, the choke tube housing collar 12 is formed of two identically shaped choke tube housing quick fasteners; two choke tube jacket clamp fastening holes 121 and one choke tube jacket clamp screw connection hole 122 are formed in each choke tube jacket quick fixing piece; similarly, a choke tube jacket clamp fastening bolt is arranged at the position of the choke tube jacket clamp fastening hole 121, and by tightening the choke tube jacket clamp fastening bolt, a tight connection relationship is established between the choke tube jacket clamp and the choke tube jacket (wherein reference numeral 123 in fig. 4 is the external position of the choke tube jacket bound by the choke tube jacket clamp); the choke tube jacket clamp fastening bolt is also matched with a matched choke tube jacket clamp fastening nut, and the choke tube jacket clamp fastening bolt also has the function of facilitating the tightening of the choke tube clamp fastening bolt by workers.
