Description
Affiliated technical field
The utility model relates to a kind of oil-submersible cable of oil exploitation submersible electric pump, especially relates to a kind of oil-submersible cable jockey.
Background technology
Submersible electric pump is widely used in field of petroleum exploitation, and oil-submersible cable is the power delivery key component of submersible electric pump.Under submersible electric pump in the well operations, need power cable to pass through with well head with jump lead or power cable and power cable between be connected.Oil-submersible cable is a triple line, and three cables core are arranged, and the heart yearn of every cable core is wrapped in insulating barrier, restrictive coating outward successively, by steel band and fixedly the oversheath formed of gum cover again with three cables core parcels.At present, oil-submersible cable connects the cables that adopt more and compresses that pipe connects, insulating tape is wrapped, the connected mode of the wrapped protection of steel band.Because of being subjected to the influence of oil well gradient and casing size, the space of tie point is limited, three cables core fold, fracture and wrapped inhomogeneous occur easily in the narrow space of the wrapped formation of insulating tape, the insulating tape performance is subjected to factor affecting such as operational environment humidity, temperature big; Welding is fixedly scalded internal insulating layer during steel band easily; Artificial wrapped steel band evenness, tightness are low, easily the connection insulation adhesive tape are damaged when going into the well, and stay the hidden failure point, are short-circuited when work; From electrical insulation properties, because insulating tape does not have seal cavity outward, tie point only depends on the insulating tape sealing, at high temperature, high pressure with have under the oil well environment of corrosive gas, the alternating current breakdown intensity of insulating cement reduces and dielectric strength increases, thereby reduce the insulation values and the withstand voltage of oil-submersible cable, make the submersible electric pump cisco unity malfunction.
The utility model content
In order to overcome tie point tie point steel band in going into the well that existing oil-submersible cable exists insulating tape of damaging, insulating tape is subjected to the operational environment factor affecting big, the insulating tape outer exposed, cause insulating cement alternating current breakdown intensity to reduce and the increase of dielectric loss intensity, the insulation values of oil-submersible cable and withstand voltage reduce, the deficiency of oil-submersible cable short circuit accident easily takes place, and the utility model provides a kind of oil-submersible cable jockey.
The technical scheme that its technical problem that solves the utility model adopts is: the oil-submersible cable jockey comprises cable, compresses pipe, three cables core are arranged in the oversheath of cable, the heart yearn of every cable core is wrapped in insulating barrier, restrictive coating outward successively, the oversheath of cable link is peeled off, the heart yearn of cable core end, insulating barrier, restrictive coating are shelled by little successively to big stepped, and the heart yearn end is inserted in the endoporus that compresses pipe.Compress outside the pipe and be set with insulating case, insulating case and stair-stepping insulating barrier, restrictive coating are set with insulating sleeve outward; The insulating sleeve of three cables core and cable connect the end has a little cable jacket to be installed in the slips assembly.The slips body of slips assembly is for radially split type, and the cavity shape of slips body is similar to the shape of cable; Clip more than 2 or 2 is installed in the slips external surface, and the slips body is fixed.Slips intracoelomic cavity cross section is a trough type, and the two ends of slips intracoelomic cavity are bigger than the middle part; There are 2 boss at slips intracoelomic cavity middle part, and insulating sleeve is between 2 boss.
The beneficial effects of the utility model are, rational in infrastructure, easy and simple to handle, reduced the influence of operational environment factor, saved the field operation time, improved cable connection point heatproof, withstand voltage and corrosion resistance, stopped the low and burnout failure that causes of oil-submersible cable junction insulation property, guaranteed that Electric Submersible Pump Unit normally moves.
