The Submersible Pump with Linear Permanent Magnet Motor (SPLM) is a cutting-edge rodless artificial lift system designed for efficient and reliable crude oil extraction. Unlike conventional sucker rod pump systems, the SPLM features a linear permanent magnet motor (LPMM) that directly drives a plunger pump in a reciprocating motion, eliminating the need for sucker rods. This significantly reduces tubing wear, mechanical failures, and maintenance costs while enhancing system efficiency.
SPLM is ideal for applications in low-permeability reservoirs, marginal wells, high-pressure environments, and offshore fields. It provides high energy efficiency, remote monitoring capabilities, and extended operational life, making it an optimal solution for modern oilfield operations.
✅ Rodless Design – Eliminates sucker rod-induced failures, tubing wear, and mechanical damage, ensuring high system reliability.
✅ High Energy Efficiency – Reduces energy consumption by 30% to 80%, with system efficiency 60% to 90% higher than traditional lifting methods.
✅ Adaptability to Harsh Conditions – Operates in high-pressure wells (30-60 MPa) and withstands temperatures up to 150°C.
✅ Long Service Life – Designed for an operational lifespan of up to 10 years, reducing downtime and maintenance costs.
✅ Remote Monitoring & Intelligent Control – Provides real-time tracking of system performance, enabling automated operation and optimization.
✅ High Torque & Low Voltage Requirements – Ensures efficient startup with low power demands, making it safer and more durable.
✅ Compact & Easy to Install – Requires minimal surface equipment, making it ideal for cluster well development and offshore platforms.
🔹 Heavy Oil Production – Efficiently handles high-viscosity crude with minimal emulsification.
🔹 Marginal & Low-Permeability Reservoirs – Suitable for fields with low natural flow rates.
🔹 Directional, Deviated & Horizontal Wells – Ideal for complex well trajectories where sucker rods face high mechanical stress.
🔹 High-Pressure Wells – Performs efficiently in downhole pressures up to 60 MPa.
🔹 Offshore & Remote Oilfields – Well-suited for locations where space and energy supply are limited.
