This study carefully designed and successfully developed a mechanical voltage
stabilizing control device. The device uses silicone oil as the key component
material of the liquid spring and 1Cr13 as the main material of the pressure
control unit, enhancing its high-pressure resistance (up to 35 MPa), oxidation
resistance, and acid-alkali corrosion resistance. By optimizing the transmission
mechanism and simplifying the pressure regulation module, the device achieves a
pressure regulation range of 0.1–21 MPa with an accuracy of ±0.01 MPa,
significantly broader and more precise than traditional devices. To address
manufacturing challenges, advanced CNC machine tools, ceramic cutting tools, and
optimized heat treatment processes (e.g., quenching and tempering) were adopted,
ensuring component machining accuracy within ±0.02 mm. Field applications in 13
oil wells demonstrated a 15.6% increase in daily oil production (from 25.5 t/d
to 29.5 t/d) and a 17.9% increase in daily gas production (from 2800
m^3/d to 3300 m^3/d), with stable casing pressure
control at 5.3 MPa. The device has created 1.225 million yuan in economic
benefits while eliminating safety hazards, providing critical technical support
for efficient and environmentally friendly oil and gas production.
