Abstract

The utility model relates to the technical field of oil exploitation, in particular to a thermal recovery wellhead assembly of an electric submersible pump. A sealing steel ring is arranged at the position where the upper end of a oil pipe hanger is in contact with the inner drift diameter of a transforming flange and is used for sealing; through holes are arranged at the corresponding parts of the oil pipe hanger and the transforming flange; when a cable passes through the through holes, fillers are used for sealing the parts between the cable and the inner wall of the oil pipe hanger and between the cable and the inner wall of the transforming flange; when the cable does not pass through the through holes, the through holes are sealed by a solid sealing assembly; and the upper end of a hanging sealing flange is connected with a lifting sealing short section and the lower end is connected with a hollow rod sealing short section. The thermal recovery wellhead assembly can meet the requirement of heat-tracing exploration of the electric submersible pump and the requirement of steam-injection exploration and overcomes the defect that the conventional wellhead device can not meet the requirements of heat-tracing exploration and steam-injection exploration of the electric submersible pump simultaneously.

Description

A kind of electric submersible pump thermal recovery well head device
Technical field:
The utility model relates to a kind of technical field of petroleum extraction, particularly a kind of electric submersible pump thermal recovery well head device.
Background technology:
In the marine oil extraction process in Yue Dong oil field, use the screw pump exploitation in advance, will carry out technological improvement at present, use the exploitation of electric submersible pump companion heat, and will annotate the vapour exploitation from now on.Need a kind of multifunctional wellhead device to satisfy exploitation of electric submersible pump companion heat and the demand of annotating the vapour exploitation simultaneously, existing wellhead assembly can not satisfy Technology Need.
The utility model content:
The technical problem that the utility model will solve provides a kind of electric submersible pump thermal recovery well head device, and this device has realized satisfying the exploitation of electric submersible pump companion heat, can satisfy the needs of annotating the vapour exploitation again.Overcome the deficiency that existing wellhead assembly can not satisfy electric submersible pump companion heat exploitation simultaneously and annotate the demand of vapour exploitation.
The technical scheme that the utility model is taked is: a kind of electric submersible pump thermal recovery well head device comprises boll-weevil hanger, crossover flange, thermal recovery flap type assembly, four-way, flange clip reducing, suspension sealing flange and table benefit core assembly; The boll-weevil hanger upper end is equipped with ring gasket with the interior latus rectum touching position of crossover flange and seals; Boll-weevil hanger and crossover flange opposite position all have through hole; When passing cable in the through hole; Adopt filler to seal between the inwall of cable and boll-weevil hanger, crossover flange, when not passing cable in the through hole, through hole adopts solid seal assembly to seal; Suspension sealing flange upper end connects the lift-off seal pipe nipple, and the lower end connects the hollow stem packoff nipple.
The beneficial effect of the utility model is: the utility model is owing to adopted boll-weevil hanger and crossover flange opposite position all to have the mode of through hole; Thereby have and both be applicable under the normal temperature electric submersible pump exploitation; Be applicable to the function of HTHP notes vapour operation again, realize the multi-functional use of a kind of well head; The utility model adopts multi-stage sealed structure, and good sealing effect has rational in infrastructure, stable performance, reliable in quality, easy to operate advantage.
Description of drawings:
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done further detailed explanation.
Fig. 1 is the structural representation of the utility model.
The structure chart of boll-weevil hanger and crossover flange when Fig. 2 accompanies thermal recovery oil for electric submersible pump.
The structure chart of boll-weevil hanger and crossover flange when Fig. 3 is exploitation via steam injection.
The structure chart of suspension sealing flange when Fig. 4 exploits for electric submersible pump companion heat.
The specific embodiment:
Like Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, a kind of electric submersible pump thermal recovery well head device comprises boll-weevil hanger 1, crossover flange 2, thermal recovery flap type assembly 3, four-way 4, flange clip reducing 5, suspension sealing flange 6 and table benefit core assembly 7; Boll-weevil hanger 1 upper end and crossover flange 2 interior latus rectum touching positions are equipped with ring gasket 10 and seal; Boll-weevil hanger 1 all has through hole 8 with crossover flange 2 opposite positions; When passing cable in the through hole 8; Adopt filler 9 to seal between the inwall of cable and boll-weevil hanger 1, crossover flange 2, when not passing cable in the through hole 8, through hole 8 adopts solid seal assembly 11 to seal; Suspension sealing flange 6 upper ends connect lift-off seal pipe nipple 13, and the lower end connects hollow stem packoff nipple 12.
It is understandable that; More than about the specific descriptions of the utility model; Only be used to the utility model is described and be not to be subject to the described technical scheme of the utility model embodiment; Those of ordinary skill in the art should be appreciated that still and can make amendment or be equal to replacement the utility model, to reach identical technique effect; As long as satisfy the use needs, all within the protection domain of the utility model.
