Abstract
The utility model discloses a wellhead hanger for electric pump wells of extrusion prevention function used in the petroleum industry, and the well head hanger is used on the well head of the electric submersible pump well. The utility model comprises a main body with a central hole, a sealing ring and a hole for laying the cable. The hole for laying the cable is positioned at the lateral side of the main body. The central line of the hole for laying the main cable is equipped with a stopper slot which is equipped with a stopper and left and right sealing strips inside. The outline structure of the stopper matches that of the main body, and the stopper is tightened within the stopper slot by the fixing bolt. When the utility model is installed on the four-way of the wellhead, no force of extrusion on the cable generates due to the rigid contact between two surfaces of the block and the main body, the cable does not be damaged, thereby ensuring the normal operation of the production and work, no loss on the well output, and having obvious economic efficiency.
Description
Technical field
The utility model belongs to the oil production equipment of petroleum industry, and particularly anti-extrusion electric pump well well head hanger uses on the well head of electric submersible pumping well.
Background technology
Existing electric submersible pumping well well head hanger generally be at main body side position axial design cable by groove and sealing ring, therefrom pass through for three strands of cables; Also have on the hanger top in addition and punch with pressing plate, the cable that will pass through is divided into three strands, and seals with weather strip.Because down-hole oil tube tubing string and electric submersible pump equipment have suitable weight, and existing electric immersible pump well well head hanger is not owing to there is the stopping means of cable, and OIH pipe weight acts on the conical surface of electric submersible pump well head, produces a radial component.Will be pressed through the cable in the well head hanger when this component reaches a certain amount of, cause cable insulation to be squeezed bad or internal short-circuit, electric submersible pump can not be turned round, oil well production can not be moved, loss operation, cost of equipment.Also can reduce the oil well production time, reduce oil well output, cause serious economy loss.
Summary of the invention
The purpose of this utility model is a design anti-extrusion electric pump well well head hanger, makes cable not be extruded damage in hanger, guarantees normally carrying out and job execution of production, avoids the oil well lost units, increases economic efficiency.
The present technique solution can reach above-mentioned purpose: anti-extrusion electric pump well well head hanger comprises the main body, joint ring and the cable that are provided with centre bore by the hole, and cable is located at the side of main body by the hole.By design limited block groove on the center line in hole, limited block and left and right weather strip are installed in it at the main body cable, the contour structures of limited block conforms to the contour structures of main body, is fastened in the limited block groove by set bolt.
The beneficial effects of the utility model are: when limited block be fixed on by set bolt form a complete revolving body on the main body after, the limited block right flank contacts with the main body rigidity, the limited block upper surface also contacts with the main body rigidity.Therefore, when the utility model being installed on the well head big four, though contacting the back with the conical surface on the utility model, the conical surface of well head big four can produce radial load, but because two faces of limited block contact with the main body rigidity, can not produce the power of extruded cable, thus can cable is crowded bad, and assurance is produced and operation is normally carried out, oil well is lost units not, has tangible economic benefit.

Fig. 2 is the left view of the utility model structural representation.
Fig. 3 is the vertical view of the utility model structural representation.
The specific embodiment
Below in conjunction with embodiment the utility model is done further detailed description: referring to Fig. 1 and Fig. 3, anti-extrusion electric pump well well head hanger comprises the main body 5, joint ring 2 and the cable that are provided with centre bore by hole 7, and cable is located at the side of main body 5 by hole 7.By design limited block groove on the center line in hole 7, limited block 1 and left and right weather strip 3 and 4 are installed in it at main body 5 cables, the contour structures of limited block 1 conforms to the contour structures of main body 5, is fastened in the limited block groove, referring to Fig. 2 by set bolt 6.Cable is to be involuted by three semicircle orifices that respectively have on limited block 1 and the limited block groove by hole 7, is equipped with seal groove in the inboard of limited block groove and limited block 1, and left and right weather strip 3 and 4 of dress also respectively has three semicircle orifices in it.
During on-the-spot the use, after down-hole string and cable were all gone into the well, down-hole oil tube was with after centre bore on the main body 5 is connected, cable is put into the cable of limited block 1 and main body 5 by hole 7 at well head, fastening with set bolt 6, again the utility model is installed on the well head big four, get final product.
