Abstract
A kind of downhole cable drags for lance, relates to oil field well technical field of tools.Comprise cylindrical shell, shaft and end socket, it is characterized in that: the top of described cylindrical shell is provided with the inner oil tube screw thread of standard, the top of described shaft is connected with piston, piston is provided with joint ring, the bottom of shaft is provided with crowfoot, the connector of piston and shaft composition is arranged on the inside of cylindrical shell, and in shaft, cover has heavy-duty spring, and described end socket is threaded connection the below at cylindrical shell.The utility model has following effect: the utility model structure is simple, and reasonable in design, processing cost is low, by the mode adopting crowfoot and cone match to block cable, efficiently solves the problem that cable breaks off relations.
Description
Technical field:
The application relates to oil field well technical field of tools, refers in particular to a kind of downhole cable and drags for lance.
Background technology:
Cable salvage is a regular content of oilfield downhole operation, in conventional art, often adopts the polished rod with crowfoot to drag for lance and salvages, and due to this structure of dragging for lance not card cable, easily breaks off relations in cable lifting process.
Summary of the invention:
The object of the application is to provide a kind of downhole cable that can overcome the deficiency existed in above-mentioned technology to drag for lance.
The object of the application realizes as follows: a kind of downhole cable drags for lance, comprise cylindrical shell, shaft and end socket, it is characterized in that: the top of described cylindrical shell is provided with the inner oil tube screw thread of standard, the top of described shaft is connected with piston, piston is provided with joint ring, and the bottom of shaft is provided with crowfoot, and the connector of piston and shaft composition is arranged on the inside of cylindrical shell, in shaft, cover has heavy-duty spring, and described end socket is threaded connection the below at cylindrical shell; Described end socket inside is provided with the conical surface.
This novel practical has following effect: the utility model structure is simple, reasonable in design, owing to not having shaped piece, so processing cost is lower, by the mode adopting crowfoot and cone match to block cable, efficiently solves the problem that cable breaks off relations.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model.
In figure 1, cylindrical shell; 2, piston; 3, joint ring; 4, shaft; 5, heavy-duty spring; 6, end socket.
Detailed description of the invention:
With reference to Fig. 1: a kind of downhole cable drags for lance, comprise cylindrical shell 1, shaft 4 and end socket 6, it is characterized in that: the top of described cylindrical shell 1 is provided with the inner oil tube screw thread of standard, the top of described shaft 4 is connected with piston 2, piston 2 is provided with joint ring 3, and the bottom of shaft 4 is provided with crowfoot, and the connector that piston 2 and shaft 4 form is arranged on the inside of cylindrical shell 1, in shaft 4, cover has heavy-duty spring 5, and described end socket 6 is threaded connection in the below of cylindrical shell 1.Described end socket 6 inside is provided with the conical surface.
During actual use, being connected on oil pipe by originally dragging for lance by standard oil gas thread, being delivered to downhole cable position; Suppress in oil pipe, piston 2 drives shaft 4 to move downward under pressure, and crowfoot stretches out; After crowfoot hooks cable, remove oily overpressure, piston 2 resets under the effect of heavy-duty spring 5, and crowfoot is retracted, and cable is stuck between the conical surface on crowfoot and end socket 6.
The utility model structure is simple, and reasonable in design, processing cost is low, by the mode adopting crowfoot and cone match to block cable, efficiently solves the problem that cable breaks off relations.
