Description
Technical field
The utility model is related to a kind of cavitation adhesive sealing lead sheath latent oil connection cable, and belonging to oil field equipment should
Use technical field.
Background technology
Existing lead sheath oil-submersible cable interconnection technique has two kinds, and one kind is the wrapped method of. g., lead tape.After pressure welding case connection, writhing number
After layer F46 insulating tapes and tetrafluoro insulating tape, every cable all overlaps wrapped three layers with. g., lead tape 1/2, and end will be with cable lead
Restrictive coating is overlapped, it is ensured that whole cable has continuous lead sheath layer.After every layer of. g., lead tape is wrapped, with strap from. g., lead tape lapping layer
One end is strangled and is pressed onto the other end. g., lead tape lap-joint is closely crimped, smooth, and it is wrapped then to carry out next layer of. g., lead tape, Zong Gongsan
Layer. g., lead tape.Another kind is lead pipe welding.After pressure welding case connection, the writhing number layer F46 insulating cements on every conductor and pressure welding case
Band, then with tetrafluoro insulating tape writhing number layer.After having twined adhesive tape, lead pipe is broken from middle straight line, with the lead pipe set for breaking
The connecting portion in whole lead cable is wrapped, set overseam is welded after being mutually lapped.
It is disadvantageous in that existing for existing lead sheath oil-submersible cable interconnection technique, first method is sealing by. g., lead tape
Between compression realize that the requirement of opposing connection packet technology is high, and operation difficulty is big.Second method is lead pipe welding, in oil field field
Under environment, welding is that a kind of speed is slower, and more difficult operation technology.The gas in lead sheathed cable connecting portion is in oil well
Body, especially H2During the corrosive gas environments such as S, easily corroded by corrosive gas, had a strong impact on the close of connecting portion
Sealing property, service life is short.
The content of the invention
Technical problem to be solved in the utility model is to overcome existing oil-submersible cable present in background technology in gassiness
The problem of the undesirable easy cavitation erosion influence service life of use sealing effectiveness in oil well, and a kind of cavitation adhesive sealing is provided
Lead sheath latent oil connection cable, the cavitation adhesive sealing lead sheath latent oil connection cable, enhances lead sheathed cable connecting portion
The sealing property and anti-pressure ability of the lead sheath layer of position, increase the service life.
The invention for solving the technical problem can reach by following technical solution：The cavitation adhesive sealing lead sheath is dived
Oily connection cable, including some cables, are connected in the middle of adjacent two cables by pressure welding case, and it is exhausted that the Exterior cable is surrounded by cable
Edge layer, is surrounded by the cable outer end difference connection cable lead sheath of cable insulation；The cable insulation and two end cable lead are protected
Insulating tape A, adhesive tape and. g., lead tape are wound successively after set external application adhesive, and heat is cased with after installing insulating tape B outside. g., lead tape additional
Shrinkage hose.
The utility model can have the advantages that compared with above-mentioned background technology：The cavitation adhesive sealing lead is protected
Set latent oil connection cable has used adhesive to seal and thermal contraction flexible pipe due to using said structure, enhances lead sheathed cable
The sealing property and anti-pressure ability of the lead sheath layer of connecting portion, eliminate the weak link of lead sheath oil-submersible cable connection, prevent
Only gas is sealed in, and improves the gas-tight corrosive power of oil-submersible cable connecting portion, it is ensured that lead sheath oil-submersible cable overall performance is consistent
Property.Excellent electrical properties, oil resistant, heat-proof aging is good, long service life of the oil-submersible cable in gassiness oil well, and economic benefit shows
Write.
Brief description of the drawings：
Accompanying drawing 1 is structural representation of the present utility model.
In figure：1- cable insulations, 2- pressure welding cases, 3- adhesive, 4- insulating tapes A, 5- adhesive tape, 6- glass tapes, 7-
Thermal contraction flexible pipe, 8-insulating tape B, 9-. g., lead tape, 10- cable lead sheaths.
Specific embodiment：
The utility model is described in further detail below in conjunction with the accompanying drawings：
As shown in Figure 1, the cavitation adhesive sealing lead sheath latent oil connection cable, including adjacent two for being connected with each other
Cable, is connected in the middle of adjacent two cables by pressure welding case, and the Exterior cable is surrounded by cable insulation 1, is surrounded by cable insulation
Distinguish connection cable lead sheath 10, the external application glue of 1 and two end cable lead sheath of the cable insulation 10 in the cable outer end of layer
Insulating tape A4, adhesive tape 5 and. g., lead tape 9 are wound after stick 3 successively, glass tape 6 is tied between adhesive tape 5 and. g., lead tape 9；Outside. g., lead tape 9
Thermal contraction flexible pipe 7 is cased with after installing insulating tape B8 additional；The adhesive tape 5 is HM adhesive tapes, and insulating tape A4 is HT insulating tapes.
Before the connection of lead sheath oil-submersible cable, first thermal contraction flexible pipe is set on cable, and pushes it to side, use clip
Clamp.After thermal contraction flexible pipe is inserted in, two lead sheathed cables are connected by pressure welding case.After cable connection, in insulating barrier, pressure
Female connector and lead sheath outer surface coated with adhesive, after smearing adhesive, successively writhing number layer HT insulating tapes sum layer HM adhesive tapes,
Insulating tape is 1/2 overlap joint winding.One layer of glass tape is wound on HM adhesive tapes, glass tape rough surface can be. g., lead tape
Offer certain resistance is provided, prevent. g., lead tape from loose situation about skidding occur.We are the. g., lead tape of 0.2mm using 1 thickness degree.
The writhing number layer HM adhesive tapes in. g., lead tape, are in order to protect. g., lead tape, while also functioning to the effect of fastening.Finally in HM adhesive tape outer covers
Upper thermal contraction flexible pipe carries out heating fastening.The connection of remaining two-phase cable is all carried out according to this step.
The cavitation adhesive sealing lead sheath latent oil connection cable, in order to strengthen the sealing property at cable connection position and resist
Pressure energy power, has used adhesive and thermal contraction flexible pipe.Adhesive is a kind of solvent-free thing, and its use can strengthen the sealing of cable
Performance.Adhesive generally uses seccotine, liquid polyurethane etc..The effect one of thermal contraction flexible pipe is to fix. g., lead tape, and two is to increase
Compressive property.Adhesive will be smeared after the layer polishing cleaning of pressure welding case, insulating barrier and lead sheath, and wind insulating tape and lead successively
Band, and finally use thermal contraction hose compression.Then it is threephase cable is wrapped to together, wrapped armour skin.
