Problems solved by technology

[0005] In addition, the current electrical control equipment for screw pump wells has some common problems: First, most of them only emphasize power saving, without considering the optimal combination of underground resources and machine rod pumps, mechanical wear, and pump body leakage. And factors such as pollution to the power grid, that is, the overall system efficiency of the screw pump well is not considered
Secondly, the performance is not stable, the failure rate is high, and the anti-interference is poor. The particularity of the oilfield power grid and the variability of the controlled object screw pump well are not considered, and there is no reasonable electrical design structure.
Therefore, the actual use effect of the current electric control equipment for screw pump wells is not very satisfactory.

Abstract

The invention relates to an intelligent monitoring device for a screw pump well, which is a high-performance industrial control device combined with optical, mechanical and electronic integration and electronic information and communication technology, and is mainly used for intelligently monitoring oil extraction of the screw pump well in oil field. The intelligent monitoring device mainly comprises a light current part and a strong current part, and is characterized in that the intelligent monitoring device takes connection of parts such as a sensor capable of measuring dynamic liquid level of the screw pump well on line, a sensor capable of measuring the torque and axial force of the screw pump well on line, a sensor capable of measuring electricity using parameters such as running current constantly and a remote wireless communication device and the like with a CPU as a core to realize the effective measurement and intelligent closed-loop control of the screw pump well. The intelligent monitoring device can avoid pump burning phenomenon of a screw pump caused by evacuation through accurate measurement and effective monitoring and dispatching, scientifically make a hot washing system according to wax deposition cause and the like to avoid phenomena such as rod breakage and the like, find eccentric wear problem in time to prolong pump detection cycle, and optimize design of the screw pump well to reasonably determine working parameters and reduce potential safety hazard and the like.

Description

Technical field [0001] The invention relates to an intelligent monitoring device for a screw pump well, which is a high-performance industrial control device combining opto-mechanical and electrical integration with electronic information and communication technology, and is mainly used for intelligent monitoring of oil production of a screw pump well in an oil field. Background technique [0002] As the screw pump oil recovery technology becomes more mature and its application scale gradually expands, how to further reduce the cost of the screw pump oil recovery technology and improve the production efficiency of oil fields has become increasingly prominent in oil field development. [0003] As the screw pump is an emerging mechanical lifting technology in oilfield development, it is not perfect in terms of technology and management, and there are phenomena such as air pumping, wax deposition, partial wear, etc., resulting in problems such as pump burning, rod breakage, and ...
