Abstract
Be a kind of submerged electric oil pump well wellhead cable sealing device disclosed in the utility model, the withstand voltage properties of electric pump well device can be improved, original wellhead assembly and flow process can be utilized, reduce Master Cost, improve well opening time.This cable sealing device comprises body, chamber body both sides are equipped with the glue injection cavities formed in the middle part of rubber cushion, its inner chamber and are communicated with the rubber injecting valve of this external installation, in rubber cushion, be provided with cable passing hole, the two ends cylindrical of body installs connecting hoop and end cap respectively, installs steel ring at the front end inner chamber of body.Changing current electric pump well needs the Well head device for electric pump well of particular design submersible electric pump cable could be connected the present situation of drawing, improve the sealing intensity of wellhead cable, improve sealing performance, produce for electric pump well and provide guarantee, particularly anticyclonic oil well effect is more obvious.
Description
Technical field
The utility model belongs to the servicing unit of petroleum industry submersible electric pump, a particularly submerged electric oil pump well wellhead cable sealing device, can improve the withstand voltage properties of electric pump well device, can utilize original wellhead assembly and flow process, reduce Master Cost, improve well opening time.
Background technology
Submersible electric pump is lifting equipment main in oil exploitation, electric pump well is due to the existence of downhole electric pump cable, Special wellhead must be adopted to be drawn by cable, the sealing of electric pump wellhead cable only adopts rubber packing directly to be sealed by the insulating layer polyvinyl chloride extruding electric-pump cable, because cable insulation anti-extrusion intensity is not high, excessive being easy to of crushing strength injures cable insulation.So adopt the electric pump well head of this sealing means, be withstand voltagely all no more than 3MPa, and on stream, because air pressure is large, casing pressure, higher than 3MPa, causes electric pump well to make a slip of the tongue cable seal place Leakage Energy, gas and cause well control risk to many electric pump wells.Electric pump well cross cable place hold need improve.
Summary of the invention
The purpose of this utility model is to provide a kind of submerged electric oil pump well wellhead cable sealing device, while can being connected with conventional wellhead assembly and using, adopts injecting glue Sealing Technology, improves cable seal performance, produces provide safeguard for electric pump well.
Technical solution of the present utility model is: a kind of submerged electric oil pump well wellhead cable sealing device comprises body, chamber body both sides are equipped with the glue injection cavities formed in the middle part of rubber cushion, its inner chamber and are communicated with the rubber injecting valve of this external installation, cable passing hole is provided with in rubber cushion, the two ends cylindrical of body installs connecting hoop and end cap respectively, installs steel ring at the front end inner chamber of body.
Remarkable result of the present utility model is: the utility model have employed rubber cushion, sealing ring and injecting glue sealing technology, changing current electric pump well needs the Well head device for electric pump well of particular design submersible electric pump cable could be connected the present situation of drawing, and draws from sleeve gate by the big four under conventional wellhead assembly.This device and sleeve gate adopt jointing clip to be connected, and first make submersible electric pump cable pass through from this device, then are sealed by the rubber injecting valve injection stop-leak compound on device.Improve the sealing intensity of wellhead cable, improve sealing performance, make its compressive resistance reach 21MPa, produce for electric pump well and provide guarantee, particularly anticyclonic oil well effect is more obvious.Use this device can use original sucker rod pump wellhead assembly or flowing well wellhead assembly, do not need to be replaced with the special wellhead assembly of electric pump well, production procedure, also without the need to reconnecting, improves rate when driving a well, and saves Master Cost, reduces cost of production.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail: see Fig. 1, a kind of submerged electric oil pump well wellhead cable sealing device comprises body 4, body 4 inner chamber both sides are equipped with the glue injection cavities 6 formed in the middle part of rubber cushion 7, its inner chamber and are communicated with the outer rubber injecting valve 5 installed of body 4, cable passing hole is provided with in rubber cushion 7, the two ends cylindrical of body 4 installs connecting hoop 3 and end cap 8 respectively, installs steel ring 1 at the front end inner chamber of body.Steel plate washer 2 is also equipped with in the outside of rubber cushion 7, in steel plate washer 2, be also provided with cable passing hole, between the cylindrical and body 4 of rubber cushion 7, be also provided with sealing ring.The front end surface of connecting hoop 3 is provided with snap-ring groove and coordinates with wellhead collar clamp.
After first electric-pump cable being drawn from sleeve gate, the steel ring 1 of this device and jointing clip 3 and body 4 are connected to sleeve gate outlet, steel plate washer 2 and rubber cushion 7 are enclosed within respectively on the electric-pump cable passed, then by rubber injecting valve 5, anaerobic adhesive is injected in glue injection cavities 6, injecting glue is after 1 hour, after anaerobic adhesive solidification, cable seal can reach 21MPa.
