Abstract
The utility model discloses a glue pouring sealing mechanism for a cable penetrating device in an oil well, which comprises a pressure cover fastened on the main body of the penetrating device, a penetrating hole of the penetrating device is internally and sequentially provided with an annular gasket and a sealing structure in a compressing way from top to bottom, an encapsulation cable is arranged by passing through the center holes of the gasket and the sealing structure and comprises a circular glue pouring die formed by the fixed connection of two semicircular bodies, the side wall of the circular glue pouring die is provided with a glue injection hole, a three-phase cable is arranged in the center hole of the circular glue pouring die, and quick-drying sealant is poured between the inner wall of the center hole of the circular glue pouring die and the outer wall of the three-phase cable. By adopting the mechanism, the cable insulating layer is integrally encapsulated in the sealant, thus effectively preventing the insulating layer from contacting with outside oil gas, solving the problem of sealing of special cables with insulating layers not resistant to oil, and simultaneously enhancing the insulating performance of the cable and being capable of effectively preventing pass of high-pressure oil gas.
Description
Technical field
The utility model relates to a kind of oil well cable penetration device, particularly oil well cable insulation has the penetration device of special protection requirement to use sealant pouring and sealing mechanism.
Background technique
Existing oil well adopts foundary weight and the stack of sealing gasket multilayer with cable penetration device structure, puts into the penetration device main body, re-uses semicircle pressure cap adjustment compacted position, afterwards through the cylinder of gland with bolt pressurization lock sealing penetration device main body and cable.The shortcoming of existing structure is: 1. when compressing semicircle pressure cap 1-3 " dynamics " when too small, rubber parts distortion deficiency and impacting force are not enough in it, cause sealing and pressure-bearing thereof undesirable; When tight semicircle pressure cap " dynamics " was excessive, the scene that penetration device foundary weight element chews cable and insulation thereof appearred in scene often, causes and does over again.2. in a single day gas-blowing phenomenon appears in the gap between three heart yearns of cable, and the method that only makes rubber seal add large deformation through the increase impacting force can't resolve gas-blowing phenomenon.3. the penetration device sealing gasket loses the elastic force of sealing along with plastic deformation, aging appears in continuity and the environmental change of time.4. foundary weight middle circle ring core is connected on the semicircular ring of outer ring through bolt, and oil well uses for a long time, and pressure reaches 21MPa sometimes, and bolt is because of the corrosion ageing failure, and the cable place causes oil and gas leakage.
It is detachable combined selfsealings mechanisms that existing oil well uses cable penetration device newest structure.This structure comprises gland, compressing tablet, under described compressing tablet, compresses successively to be provided with cable and to pass assembly and sealing gasket.The advantage that this structure has is: improve sealing effect, increase sealing reliability.This structural disadvantages is: for the part cable, its isolation layer does not possess oil resistance and the anti-ability of hindering.When three cables sealed respectively, isolation layer leaked cruelly and under oil and gas conditions, influences insulating performance of cable and working life.
Summary of the invention
The purpose of the utility model is to overcome the deficiency of prior art, provides a kind of oil well cable penetration device of effective protection cable insulation to use sealant pouring and sealing mechanism.
In order to achieve the above object, the technological scheme of the utility model employing is:
Oil well cable penetration device is used sealant pouring and sealing mechanism; It comprises the gland that is fastened on the penetration device main body; In the through hole of described penetration device, compress successively from top to bottom and be provided with annular gasket and sealing configuration; The embedding cable passes the center hole setting of described pad and sealing configuration, and described embedding cable comprises the circular encapsulating mould that is made up of two semiround body fixed connections, on described circular encapsulating mould side wall, has gum-injecting port; Threephase cable is arranged in the center hole of described circular encapsulating mould, and between the center bore inner wall of described circular encapsulating mould and threephase cable outer wall, irritating has fast dry seal glue.
The advantage of the utility model is: 1. cable insulation integral body is potted in fast dry seal glue inside; Effectively stop isolation layer to contact with outside oil gas; Solved the not special cable sealing problem of oil resistant of isolation layer, increased insulating performance of cable simultaneously and can effectively stop high-pressure oil gas to pass through.2. the encapsulating mould of two semicircles, matching part posts caulking gum, prevents that effectively down-hole high pressure oil gas from leaking along the encapsulating die gap, increases the cable seal reliability.3. 2 semi-rings of foundary weight assembly and parallels assembly adopt convex-concave to cooperate, and have effectively prevented 2 semicircular ring dislocation during the oil well seal operation, and are convenient and reliable.
