Intelligent Control System Solution for Oil Extraction Parameters in Beam Pumping Units
The intelligent control system for pump jack oil extraction process parameters uses the fullness of the pump jack well power diagram as a basis, applies reasonable control strategies, optimizes the design of the pump jack well's operating system, adjusts the oil extraction capacity of the pump jack well, achieves a reasonable balance between oil well fluid production and energy consumption, thereby achieving increased production and reduced consumption, improving management, enhancing the construction level of the oilfield's digital oilfield, and further improving the control effect of pump jack wells.
The system effectively combines intelligent programmable controllers and variable frequency technology. For different oil wells, it can adopt fast downstroke and slow upstroke speeds, or slow downstroke and fast upstroke speeds, and steplessly adjust the pump jack strokes. The stroke adjustment range is 1-20 times/minute, and the stroke travel time adjustment range is 3-30 seconds/time. According to the dynamic load changes of the oil well indicator diagram, the corresponding control program software can be used to change the up and down stroke speeds of the pump jack at any time (fast upstroke can reduce pump leakage, slow downstroke can improve effective stroke, and improve the pump's filling coefficient). Remote control is also possible.
(1) Improve pump filling coefficient and reduce lifting losses.
(2) Save electricity by more than 20%; improve pump efficiency by more than 30%.
(3) Achieve soft start, reduce starting current, reduce impact on the power grid, and reduce the installed capacity of the pump jack transformer by more than 40%.
(4) Automatic restart after power failure, no manual operation required, reducing downtime.
(5) Reduce ineffective wear and tear on the pump jack and pump, extending the service life of the equipment.
(6) Achieve single-well electricity metering, allowing for intuitive assessment of electricity consumption cost per ton of oil.
(7) Dynamic parameter adjustment function: adjust operating parameters at any time according to oil well production conditions, making the pumping parameters of the pump jack more reasonable and achieving increased production.
(8) Can be assembled into a mobile variable frequency energy-saving and efficiency-increasing test device for variable-speed oil extraction tests on pump jack wells to determine the optimal operating parameters and achieve increased production through parameter adjustment.
