Problems solved by technology
[0002] During the use of the electric submersible pump, as the amount of oil in the oil well gradually decreases, the liquid level gradually decreases and eventually the liquid level is lower than the height of the submersible pump motor, and the terminal of the submersible pump cable connected to the submersible pump motor cannot be used. If this phenomenon is recognized, the power supply cannot be cut off in time, which will cause the motor of the submersible pump to run idling and eventually be burned and scrapped

The invention discloses a temperature monitoring type submersible oil pump cable. A pressure gauge cable core comprises first conductors, a polypropylene insulation layer coats outside each first conductor, and a first polypropylene protection layer, a bearing armored steel wire layer and a polypropylene outer jacket sequentially coat outside the three first conductors after the first conductors are twisted; a compensation cable core comprises second conductors, a polypropylene insulation layer coats outside each second conductor, and a silicone rubber outer jacket coats outside the two second conductors after the two second conductors are twisted; and a submersible oil pump cable core comprises third conductors, and a polypropylene insulation layer, a second polypropylene protection layer and an oil-resistant cushion layer sequentially coat outside the third conductors. In the temperature monitoring type submersible oil pump cable, a cable special for an underground flow measurement system and a thermocoupling compensation guide line are added on the basis of the original submersible oil pump cable, dual protection on an electric motor in an oil well is achieved, the service efficiency of the electric motor of a submersible oil pump can be greatly improved, and the service life of the electric motor also can be prolonged.
Description
technical field [0001] The invention relates to the technical field of electric submersible pumps, in particular to a temperature measuring and monitoring type submersible pump cable. Background technique [0002] During the use of the electric submersible pump, as the amount of oil in the oil well gradually decreases, the liquid level gradually decreases and eventually the liquid level is lower than the height of the submersible pump motor, and the terminal of the submersible pump cable connected to the submersible pump motor cannot be used. If this phenomenon is recognized, the power supply cannot be cut off in time, which will cause the motor of the submersible pump to run idling and eventually be burned and scrapped. Contents of the invention [0003] The object of the present invention is to provide a temperature measurement and monitoring type submersible pump cable in order to make up for the defects of the prior art. [0004] The present invention is achieved ...
