Abstract
The utility model provides a cable of an electric submersible pump. The cable of the electric submersible pump is provided with a sheath having a flat cross section. Three cable lines and a temperature-measuring optical fiber line are arranged side by side in the sheath and an armor layer wraps the sheath. According to the utility model, by arranging the cable lines and the temperature-measuring optical fiber line, the cable of the electric submersible pump has functions of power transmission and auxiliary temperature measurement at the same time, so that defects of the prior art are made up.
Description
Technical field
The utility model belongs to petroleum production engineering field, in particular to a kind of be the matching used submersible electric pump cable of electric submersible pump.
Background technology
Oil-immersed pump power cable is the matching used private cable of Electric Submersible Pump Unit, is laid in oil well, and cable lower end is connected with the jump lead of downhole electrical motor, and upper end is connected with ground control cubicle, for Set under a well transmits electric energy.Oil-immersed pump power cable generally has can be divided into two kinds of circular and flats, is subject to the restriction of oil well casing small space, and common oil-immersed pump power cable be take flat as main, and the construction of cable is mainly partly comprised of conductor, insulating barrier, barrier layer, restrictive coating, armour etc.
In use, the general mode that is bundled in oil-pipe external wall that adopts of oil-immersed pump power cable, with oil pipe G.I.H.Because condition of work in oil well is severe, often in high temperature, high pressure, and in the very strong environment of the corrosivity such as oily.Existing electric-pump cable generally only has the effect of transferring power, Set under a well is not carried out the function of temperature monitoring, need to adopt distribution type fiber-optic, thermocouple temperature measurement technology etc. to realize temperature monitoring to down-hole string and unit, but also adopt with oil pipe binding mode and go into the well because temperature-measuring optical fiber line is the same with cable, and oil pipe bundlees two cables outward and can make oil well operation difficulty of construction strengthen simultaneously, more easily cause cable to be extruded injury and lost efficacy, while making to apply, have certain difficulty in electric pump well.
In view of this, the design people, according to the Production design experience of being engaged in for many years this area and association area, develops a kind of submersible electric pump cable, the problem existing to solving prior art.
Utility model content
The purpose of this utility model is to be to provide a kind of submersible electric pump cable, by cable and temperature-measuring optical fiber line are set, has the function of while transmission of power and auxiliary thermometric, has overcome the defect of prior art.
For this reason, the utility model proposes a kind of submersible electric pump cable, it is provided with the sheath that a cross section is flat, is provided with side by side three cables and a temperature-measuring optical fiber line in described sheath, the coated armour in its outside.
Submersible electric pump cable as above wherein, is filled with insulating material in the space outside cable and temperature-measuring optical fiber line in described sheath described in each, and described insulating material is polypropylene.
Submersible electric pump cable as above; wherein; described cable comprises a conductor, an insulating barrier, a barrier layer and a protective layer; described insulating barrier, barrier layer and protective layer are coated on the outside of described conductor from the inside to the outside successively; described temperature-measuring optical fiber line comprises that one is positioned over the temperature-measuring optical fiber in steel pipe, and the outside of described steel pipe is coated with a fiber optic protection layer.
Submersible electric pump cable as above, wherein, described conductor is for being drawn the wire forming by oxygen-free copper bar, and described insulating barrier is made by polypropylene, and described barrier layer is made by polytetrafluoroethylene, and described protective layer and fiber optic protection layer are made by nitrile rubber.
The submersible electric pump cable the utility model proposes, is provided with cable and temperature-measuring optical fiber line, by both are assembled into one, supports the use with electric submersible pump, has realized the dual purpose for Set under a well transferring power and temperature monitoring.
