Abstract
The utility model belongs to the technical field of oil exploitation equipment, relates to a device for sealing a tubing head perforation and partial cables penetrating the perforation, and aims at resolving the problems that the existing sealing operation of the cable and the sealing device of the tubing head needs to be operated on the spot, the operation is complicated, and cost of a second replacement is high once the sealing fails. The device for sealing the tubing head perforation and partial cables penetrating the perforation comprises a cable sleeve connecting the perforation and the partial cables, and a sealing member sealing the cable sleeve and the perforation, wherein the cable sleeve is fixed on the partial cables through sealing glue. The technical scheme effectively resolves the existing problems.
Description
Technical field
The utility model belongs to the oil exploration equipment technical field, relates to the device that a kind of sealing oil tube head is bored a hole and passed the part cable of described perforation.
Background technology
Oil field electric power recovers the oil, and cable need pass tubing head and arrive ground, and present method is to remove the armature of cable part at the scene, realizes the sealing of cable and tubing head by seal and corresponding mechanism.See Fig. 1, this figure has reflected the structure of the sealing device of a kind of existing realization cable and tubing head sealing, this device comprises sealing ring 5, gland 3 and housing screw 4, during use, removes earlier the armature of cable part at the scene, sealing ring 5 on cable joint-box then, gland 3 and housing screw 4 subsequently, penetrate cable the perforation of tubing head, screw gland 3 and screw housing screw 4 and compress sealing ring 5, thereby realize sealing between cable and the tubing head.
Yet, because tubing head comprises tubing hanger 1 and the upper flange 2 that is connected with tubing hanger 1 flange, so cable must pass upper flange 2 and tubing hanger 1 simultaneously, also be that above-mentioned sealing need be done twice at least, this mode execute-in-place difficulty is big, sealing was lost efficacy easily, and in a single day lost efficacy, and the cost that secondary is changed is very high.
The utility model content
Technical problem to be solved in the utility model is to have now the seal operation of the sealing device of realizing cable and tubing head sealing and need carries out at the scene, and complex operation, in case sealing failure, the very high problem of cost that secondary is changed, and a kind of sealing oil tube head perforation is provided and passes the device of the part cable of described perforation at this problem.
The utility model solves the problems of the technologies described above by the following technical programs:
A kind of sealing oil tube head perforation and pass the device of the part cable of described perforation, it is characterized in that this device comprises the described perforation of connection and the cable body of described part cable and the seal member of hermetically-sealed cable body and described perforation, described cable body is fixed on the described part cable by fluid sealant.
After adopting said structure, the technical staff can be when making cable, the cable body is set on cable in advance, thereby do not need to remove at the scene the armature of cable part, and loaded down with trivial details operations such as sealing ring, gland and housing screw are installed, also avoided simultaneously because the problem of the seal failure that error hand-manipulated causes.
On the basis of above technical scheme, the seal member of described hermetically-sealed cable body and described perforation comprises the jut that is arranged on the cable body, and cable joint-box external surface and described bore inner surface are complementary, and described jut closely is connected with described perforation.
Adopt epimere cable body need not carry out repeatedly seal operation (for example the sealing device of described a kind of existing realization cable of this specification background technology part and tubing head sealing need carry out twice sealing at least respectively according to upper flange and tubing hanger) at different seal members with the sealing means of tubing head perforation, time saving and energy saving.
Description of drawings
The structural representation of Fig. 1 sealing device that to be a kind of existing realization cable mentioned of this specification background technology part seal with tubing head;
Fig. 2 is described a kind of sealing oil tube head of embodiment and the structural representation that passes tubing head part Seal of Cables device.
Embodiment
Embodiment
See Fig. 2, a kind of sealing oil tube head perforation and pass the device of the part cable of described perforation, this device comprises the cable body 8 of described perforation of connection and described part cable and the seal member of hermetically-sealed cable body 8 and described perforation, tubing head is divided into tubing hanger 6 and is connected by flange with tubing hanger 6, be positioned at the upper flange 7 on tubing hanger 6 tops, accordingly, the tubing head perforation comprises tubing hanger perforation and upper flange perforation.
Described cable body 8 is fixed on the described part cable by fluid sealant, described seal member comprises the jut that is arranged on cable body 8, this jut can be provided with a plurality of, and closely be connected with described perforation, thereby play the effect of hermetically-sealed cable body 8 and tubing head perforation, (the part cable body that also promptly is connected with the tubing hanger perforated bottom) is provided with jut 9 to present embodiment only in cable body 8 bottoms.
In order to prevent between the perforation of cable body 8 and tubing head slide relative to take place, influence the sealing effectiveness between cable body 8 and the tubing head, cable body 8 outer surfaces and tubing head bore inner surface are complementary.
During use, only need that cable body 8 is passed the tubing head perforation and get final product.
More than show and described basic principle of the present utility model, principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present utility model; the utility model also has various changes and modifications under the prerequisite that does not break away from the utility model spirit and scope, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
Claims (2)
1. sealing oil tube head perforation and pass the device of the part cable of described perforation, it is characterized in that this device comprises the described perforation of connection and the cable body of described part cable and the seal member of hermetically-sealed cable body and described perforation, described cable body is fixed on the described part cable by fluid sealant.
2. a kind of sealing oil tube head perforation according to claim 1 and pass the device of the part cable of described perforation, the seal member that it is characterized in that described hermetically-sealed cable body and described perforation comprises the jut that is arranged on the cable body, cable joint-box external surface and described bore inner surface are complementary, and described jut closely is connected with described perforation.
