Detailed description of the invention:
Embodiments of the invention are described in detail in conjunction with accompanying drawing.
Well liquid of the present invention refers to the mixture liquid of crude oil, water and sand.
Invention components I is made up of tubing anchor 1, submersible electric machine with oil 2 and motor protecter 3, and the effect of tubing anchor 1 is just
Be play and be stably fixed to sleeve pipe 14 together with, thus protect native system stable and reliable in work, the effect of submersible electric machine with oil 2 is exactly
Giving screw pump 9 and provide power, be allowed to well liquid and be transported to ground by screw pump 9, guarantor is played in the effect of motor protecter 3 exactly
Protect the effect of submersible electric machine with oil 2, it is ensured that submersible electric machine with oil 2 is stable and reliable in work.
Invention components II is made up of reduction gear oil tank 4, latent oil reductor 5 and reductor protector 6, reductor
The effect of fuel tank 4 gives the effect that latent oil reductor 5 provides lubrication exactly, and latent oil is protected in the effect of reductor protector 6 exactly
Reductor 5 is stable and reliable in work.
Invention components III is by lower lifting 7, suction apparatus 8, screw pump 9, suspension connection device 10 and sand discharge off-load list
Stream device 11 is formed, and the effect of lower lifting 7 connects reductor protector 6 and suction apparatus 8 exactly, at suction apparatus 8
Around being machined with several aperture, well liquid is through this aperture and enters in screw pump 9, and the effect of screw pump 9 is exactly defeated for well liquid
Delivering to ground, the effect of suspension connection device 10 is to ensure that screw pump 9 is stable and reliable in work, sand discharge off-load single flow device 11
Effect is to ensure that well liquid is flowed out by this sand discharge off-load single flow device 11 after screw pump 9 quits work.
The effect of power cable 12 of the present invention gives submersible electric machine with oil 2 exactly and provides electric power, owing to putting when submersible electric machine with oil 2 works
Enter the degree of depth of down-hole 1000-2500 rice, so the length of power cable 12 also will be at 1000-2500 rice, for power cable 12
Uniform force, so on petroleum pipeline 18, being provided with strain relief clamp 13 every a certain distance, the effect of sleeve pipe 14 is just
It is, it is ensured that the present invention is stable and reliable in work that well head 15 is exactly the device between ground and well, petroleum pipeline in order to the borehole wall does not caves in
The effect of 18 is exactly to carry well liquid earthward.
The liquid level monitoring device 16 of the present invention and the effect of Intelligent remote monitoring system 17 use a network for remotely exactly
The device controlled, this remotely intelligently monitoring device can detect the data such as producing fluid level, casing pressure, electric current, voltage, discharge capacity, energy in real time
