Abstract
The utility model relates to a radial horizontal well and well logging operation technology field, in particular to hawser sealing device. The device's sealed body internally mounted has the packing, and packing both ends inner wall is the conical surface that outer imperial palace is little, presses the cap in the sealed body upper end on the wall connection presses cap upper end internally mounted to have last copper ring on, and the wall connection pushes down the cap in the sealed body lower extreme, and it has lower copper ring to push down cap lower extreme internally mounted, and the packing lower extreme pushes up on pushing down the cap presses the cap lower extreme to compress tightly the packing on, and it division has the oil filler point that is linked together with the packing to seal up on the body lateral wall. The utility model discloses a sealing between cable and the oil pipe, sealed effectual, the cable wearing and tearing condition improves, prolongs the life of winch hawser, makes things convenient for the instrument to play to reach down blowout control, simple structure, easy processing. It is poor to have overcome the sealed effect of present well head cable sealing device, and it is not enough that hawser life shortens.
Description
Technical field:
The utility model relates to radially horizontal well and logging operation technical field, particularly a kind of hawser sealing device.
Background technology:
In radial well construction, when arriving the object degree of depth under instrument is with winch cable, high pressure to be beaten from well head to water filling in oil pipe, requiring to keep sealing state between hawser and oil pipe.In addition, in some project of logging operation, well head is also needed to pressurize by technological requirement.The principle of the wellhead cable blowout hookup of current logging Application is extruded by external force, makes packing generation deformation in device, to reach the sealing to wellhead cable.Cable and the packing phase mutual friction sealed in well logging work progress, packing and the equal serious wear of hawser, even seal failure that sealing effectiveness is not good enough, and hawser shortening in application life.
Utility model content:
The technical problems to be solved in the utility model is to provide a kind of hawser sealing device, the arrangement achieves the sealing between cable and oil pipe, good sealing effect, cable abrasion condition improves, and extends the application life of winch hawser, facilitates instrument to remove and blowout control, structure is simple, is easy to processing.Overcome existing well head cable sealing device sealing effectiveness poor, the deficiency of hawser shortening in application life.
Technical solution adopted in the utility model is: a kind of hawser sealing device, comprises seal body; Seal body inside is provided with packing, packing two ends inwall is the little conical surface of outer imperial palace, seal body upper end inwall connects upper pressing cap, inside, upper pressing cap upper end is provided with copper ring, seal body lower end inner wall connects lower pressing cap, and inside, lower pressing cap lower end is provided with lower copper ring, and packing lower end withstands on lower pressing cap, upper pressing cap lower end compresses packing, seal body sidewall has the oil filler point be connected with packing.
The beneficial effects of the utility model are: the utility model achieves the sealing between cable and oil pipe, good sealing effect, and cable abrasion condition improves, and extend the application life of winch hawser, and facilitate instrument to remove and blowout control, structure is simple, is easy to processing.
Accompanying drawing illustrates:
Below in conjunction with the drawings and specific embodiments, the utility model is described in more detail.
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention:
As shown in Figure 1, a kind of hawser sealing device, comprises seal body 1; Seal body 1 inside is provided with packing 6, and packing 6 two ends inwall is the little conical surface of outer imperial palace, adopts helical cut, conveniently penetrates cable.Seal body 1 upper end inwall connects upper pressing cap 2, and inside, upper pressing cap 2 upper end is provided with copper ring 3, and seal body 1 lower end inner wall connects lower pressing cap 4, and inside, lower pressing cap 4 lower end is provided with lower copper ring 5, and upper copper ring 3, lower copper ring 5 all do formula structure into two, conveniently assemble and disassemble.Packing 6 lower end withstands on lower pressing cap 4, and upper pressing cap 2 lower end compresses packing 6, seal body 1 sidewall has the oil filler point 7 be connected with packing 6.
During use, copper ring and conductive cable contacts, alleviate the wearing and tearing of cable as far as possible in construction.Seal body 1 has reserved seat elevator position, and seal body 1 is milled with four directions, conveniently makes pipe wrench.
During use, cable is successively through upper copper ring 3, upper pressing cap 2, packing 6, lower pressing cap 4, lower copper ring 5.The utility model is connected with the four-way upper end of quick acting well head, and winch hawser starts to transfer radial well instrument, after instrument arrives the object degree of depth, lower pressing cap 4 screw thread is tightened to position, slowly tighten upper pressing cap 2 with spanner and press down packing 6, packing 6 and cable are fitted closely gradually, plays sealing function.Unclamp upper pressing cap 2, depressurization.Now cable carries instrument on can starting.Packing is consumable accessory, can install a bottom jib root or whole replacing additional after there are wearing and tearing.After each operation completes with grease gun by oil filler point 7 to sealing dispensing stop-leak compound.
Be understandable that, above about specific descriptions of the present utility model, the technical scheme described by the utility model embodiment is only not limited to for illustration of the utility model, those of ordinary skill in the art is to be understood that, still can modify to the utility model or equivalent replacement, to reach identical technique effect; Needs are used, all within protection domain of the present utility model as long as meet.
