Abstract
The utility model discloses a high voltage cable joint that is used in the heating and bailing oil of the exploitation in oil field. The utility model adopts a structure that the upper end of the joint is connected with large power high tensile-strength cables, the lower end of the joint is connected with a heater, the cable is provided with a double layer steel wire armored structure and two power wires and four signal lines are positioned in the structure. Therefore, three connectors are positioned in the cable joint. A sealing and locking device with an upper layer, a middle layer and a lower layer are adopted to ensure the sealing performance of the cable joint. The two technical measures of filling insulate oil into the cavity and using the imported fluoroplastic insulate bush (The insulating bush ensures that the joint can endure the working environment of high voltage and high current) are adopted to ensure the good insulation of the cable joint and solve the problem that present cable joint cannot transmit a high voltage of 1000 V and a high current of 50 A. The utility model can be widely used in the oil field operation of heavy oil and high pour point oil heating and bailing oil.
Description
Technical field:
The utility model relate to a kind of oil field recover the oil in heating drag for oil matched " high pressure cable joint ".
Background technology:
The at present domestic scene of recovering the oil in the oil field, several work such as measurement while drilling, side well all need to be equipped with cable joint, so that with cable and downhole tool, instrument couples together, cable joint is design as the case may be then, cable that existing cable joint connected and instrument instrument are mainly used to transmit various signals, use DC electronic, and voltage is generally less than 80V, electric current is not more than is 70mA.Then use alternating current in heating in the oil salvage operation, therefore, need to use high-power high-intensity be that through-put power can reach 50KW, wherein voltage can be reached 1000V, the electric current transmission cable up to 50A.Existing cable joint can't meet the demands.
The utility model content:
Can not satisfy in recovering the oil in the oil field particularly at viscous crude in order to overcome the existing cable joint, height coagulates needs to use high-power high-intensity transmission cable and down-hole lubricator and the deficiency of dragging for the required cable joint of oily instrument in the oily oil salvage operation, the utility model provides a kind of high-voltage cable joint not only to satisfy needs high-power, high strength transmission cable joint, and has a good insulation preformance, good airproof performance can bear high voltage and dismounting, change conveniently.
The technical scheme that its technical problem that solves the utility model adopts is: the high-voltage cable joint upper end links to each other with high-power high-strength cable, and the lower end links to each other with heater.High-tension cable is the double wire armor structure, in 2 power lines and 4 holding wires are arranged, therefore, be provided with 3 binding posts in the high-voltage cable joint.For guaranteeing the cable joint sealing property, in high-voltage cable joint, be provided with upper, middle and lower-ranking sealing, locking device; Employing is injected insulating oil and is used two technical measures of import fluoroplastic insulation cover to guarantee the high-voltage cable joint good insulation preformance to the high-voltage cable joint inner chamber, and the fluoroplastic insulation cover can also guarantee that this joint bears high voltage and high current work environment simultaneously; To divide the wire connection head to put into gland during connection earlier, then cable is penetrated in the branch wire connection head, the cable outer layer steel wire upwards overturns near a minute wire connection outer wall, compress the steel wire that turns up by the steel wire pressure cap, again lock cover is screwed on the screw thread of gland lower end, prevent the vertical slippage of steel wire pressure cap, cable seal nipple A upper end cross section is 3 groups of shoulder holes of distribution evenly, power line and holding wire in the cable pass from these 3 groups of holes respectively, middle part, every group of hole is provided with seal, and the seal upper end is compressed by hold-down bolt.In the cavity of cable seal nipple A, power line, holding wire are linked to each other with the binding post of import fluoroplastic insulation cover A upper end.Then with on the step of import fluoroplastic insulation cover Building A in cable seal nipple A cavity.There are 3 copper sleeve A import fluoroplastic insulation cover A lower end; Heating wires on the heater (cable, holding wire) is linked to each other with the binding post of import fluoroplastic insulation cover B lower end in the cavity of cable seal nipple B, on the step of import fluoroplastic insulation cover Building B in cable seal nipple B cavity.There are 3 copper sleeve B import fluoroplastic insulation cover B upper end; After the cable joint upper and lower side all connects, cable seal nipple A end flanges is inserted cable seal nipple B top shoulder, again end fitting is connected with cable seal nipple A outer wall thread at last.Injecting insulating oil to the insulating oil hand-hole respectively then seals with lead pad and hexagon socket head cap screw.
The beneficial effects of the utility model are, this joint design is simple, convenient disassembly, and insulation, good seal performance can be born the voltage of harmful 1000V and the alternating current of 50A.
