Abstract
The utility model relates to a multifunctional electric pump hanger used for an electric pump in an oil field, comprising a cable sealing pressure cap 1, a cone split sealing piece 4, a cable 8, a nitriding anti-theft tube 9 and an anti-theft platen 10 and etc. the sealing pressing ring 3 is connected with the cone split sealing piece 4 through a pin, one end of the nitriding anti-theft tube 9 is arranged inside the sealing shell 5, while the other end is arranged inside the anti-theft platen 10; the anti-theft platen 10 is connected with a hanger body 11 through a platen anti-theft screw 15, the cable 8 goes through the hanger body to change the hanger body into an integrated body, therefore, the cable is uneasy to be extruded and damaged, and the sealing property at a well mouth is good; the side extrusion sealing is changed into the longitudinal extrusion expanding sealing, so that the cable is not easy to be damaged and the sealing property is good; the sealing pressure cap is provided with a damper, therefore, the cable and an insulating layer does not be damaged in the process of the pressure sealing; even the cable breaks off, the cable maintains above the pressure cap with the damper, therefore, the cable can be connected with the well mouth without any extra power.
Description
Relate to the field
The utility model is used for a kind of multi-functional electric pump hanger on the electric pump well of oil field.
Background technology
At present, former electric pump hanger, opening from the side, well head cable are by the lateral compression sealing, and after cable insulation crushes injury, but owing to squeeze the difference of hindering degree, some problem detects not come out with instrument at the scene.Be subjected to the impact of powerful electric current a certain period after start, caused the well head cable to burn; Former electric pump hanger, opening from the side, poor sealing performance in washing well process and under the effect of some well self pressure, causes liquid to leak from the cable thorn of electric pump hanger, directly stings bad well head cable when serious, has caused pollution, has influenced construction; Former electric pump hanger is split type, and poor rigidity owing to be subjected to the influence of factors such as derrick footing, earth anchor, hook centering degree and construction quality, very easily causes the damage of hanger self; Former electric pump well platen does not play antitheft effect to the well head cable, can't connect after cable is lost; Even more serious is that some well has caused downhole cable or unit to burn because the well head cable burns, and has increased unnecessary work operations amount, has reduced crude output in the unit interval.Above problem has all caused last power to connect the well head cable.
Technology contents
The purpose of this utility model is to provide that a kind of to have hanger, a cable not fragile, good airproof performance, and make cable possess anti-theft feature, it is simple to have construction, easy to operate, safe and reliable, even cable is lost or construction quality problem occurred, need not go up the multi-functional electric pump hanger that power can keep in repair yet.
The utility model is achieved in that
Comprise cable seal pressure cap 1, drag reduction bearing 2, seal joint 3, cone split seal 4, seal casinghousing 5, steady pin 6, safety pin 7, cable 8, the antitheft pipe 9 of nitriding, antitheft platen 10, hanger body 11, hanger seal 12, hanger pressure ring 13, hanger pressure cap 14, platen anti-theft screw 15, groove 16, cable seal pressure cap 1 is connected with seal casinghousing 5, seal joint 3 is connected with taper split seal 4 pins, drag reduction bearing 2 is arranged on the seal joint 3, antitheft pipe 9 one ends of nitriding place in the seal casinghousing 5, the other end places in the antitheft platen 10, antitheft platen 10 is connected by platen anti-theft screw 15 with hanger body 11, hanger seal 12 is arranged successively at the bottom of this device, hanger pressure ring 13, hanger pressure cap 14 is interspersed with cable 8 in the device.
The utility model also adopts following technical scheme:
Steady pin 6 is arranged on the seal joint 3.
On the taper split seal 5 groove is arranged.
Steady pin 6 is connected with the groove of taper split seal 5.
There is safety pin 7 cable seal pressure cap 1 both sides.
Fluted 16 on the hanger body 11, the tongue corresponding with groove 16 arranged on the hanger seal 12.
Advantage of the present utility model is:
1. hanger body is made into as a wholely, so be difficult for squeezing hindering cable, and the well head good airproof performance.
2, antitheft Guan Shangyi is passed through at original sealing position, and lateral compression is sealed, change the swollen sealing of rising of vertical extruding into, hinder, possessed good sealing property simultaneously thereby cable is difficult for squeezing.
3, seal pressure cap has used damping device, can not damage cable and insulating layer in the pressurization process.
4, having installed antitheft pipe of nitriding and antitheft platen additional on hanger, under the protection of anti-theft screw, antitheft platen, the antitheft pipe of nitriding, also is more than the drag reduction pressure cap even cable is lost, and does not go up power like this and just can connect the well head cable.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Concrete enforcement
Below in conjunction with accompanying drawing the utility model is further described:
As shown in drawings, the electric pump hanger after the improvement is by hanging hermetic unit, cable seal part, guarding portion, and three parts are formed.
Hanging hermetic unit is made up of hanger body 11, hanger seal 12, hanger pressure ring 13, hanger pressure cap 14.Work to hang down-hole string, sealing well head.
The cable seal part is made up of cable seal pressure cap 1, drag reduction bearing 2, seal joint 3, cone split seal 4, seal casinghousing 5.Play hermetically-sealed cable.
Guarding portion is by the antitheft pipe 9 of nitriding, antitheft platen 10, and anti-theft screw 16 is formed, and carries out cascade protection, loses and also do not use the purpose that power just can connect the well head cable even reached cable.
Sit the hanger method: following intact fulgurite, earlier hanger is connected with fulgurite, cable 8 is passed along the hanger side opening; Platen is put in examination, and platen anti-theft screw 15 holes are consistent with the big four screw; The good hanger of seat; Antitheft pipe 9 and seal pressure cap 1 are penetrated from cable head, pull down part cable armour skin according to antitheft pipe 9 length at the sealing position, and antitheft pipe 9 is tightened on the hanger side opening; Install platen 10; Cable is gathered around several centimetres downwards, simultaneously taper split seal 4 is filled in the sealed tube, tighten pressure cap 1 and get final product.
Pull out the hanger method: remove well head earlier, anti-theft screw 15, platen 10; Unload seal pressure cap 1, go up portable cable 8 gently, take out seal 4; Unload antitheft pipe 9, get final product and carry hanger.
Connect the well head cable methods: unload anti-theft screw 15, platen 10; Unload seal pressure cap 1, take out
Seal 4; Unload antitheft pipe 9, stube cable 8.Get final product by opposite operation in tandem then.
