The liquid-driven rodless oil production system consists of driving equipment, control equipment, and downhole equipment.
The liquid-driven rodless oil production system consists of driving equipment, control equipment, and downhole equipment.
Driving Equipment: Includes a motor and high-pressure water pump, responsible for providing power to the downhole pump unit.
Control Equipment: Includes a control cabinet, water tank, directional valve system (directional valve + hydraulic station), filter, solenoid valve, flow meter, etc.
Downhole Equipment: Downhole oil pump.
① Stable operating pressure of the hydraulic cylinder ensures a long system lifespan.
② Compact size, lightweight, and easy transportation, making it particularly suitable for operations in marshlands, offshore platforms, and mountainous areas.
③ Easy to achieve long strokes and low stroke frequencies, with stepless adjustment of stroke and frequency.
④ Strong adaptability to heavy loads, meeting the needs of deep wells and heavy oil well extraction.
⑤ High efficiency, with significant energy-saving effects after adding counterweights.
⑥ Enables remote data transmission and automated control of oil wells.
⑦ Capable of driving multiple wells simultaneously from a single platform (one machine for multiple wells).
⑧ Closed-loop circulation with no leakage points, ensuring no fluid loss and ultra-long-distance transmission. The fluid delivery pipe has no joints, preventing leakage.
The liquid-driven rodless oil production system is mainly used in oil fields such as Xinjiang, Yanchang, and Jilin, as well as for dewatering and gas extraction in coalbed methane and shale gas wells. It has been applied in over 20 wells, with the longest continuous operation reaching 1,150 days and still ongoing. The system operates smoothly, requires simple maintenance, and has proven to be stable, effectively solving customer problems.
