Product Introduction
Electric Submersible Pump (ESP) is a mainstream rodless lifting equipment in oil exploitation, with core advantages: large displacement, high lift, and strong automation, suitable for high-yield, deep and complex wells.
Types and Characteristics of Equipment
Type
Conventional Centrifugal Type (Mainstream): Multi-stage centrifugal pump, with highdisplacement and high lift, sensitive to sand and gas content Submersible Screw Pump: Suitable for heavy oil and high sand content wells, friendly todeviated wells, with limited displacement
Features
Permanent Magnet Synchronous Type (New Type): High efficiency and energy saving,variable frequency speed regulation available, large starting torque Classified by Scenarios: Land General Type, Offshore Anti-corrosion Type, Heavy Oil High-temperature Resistant Type, Small Casing Special Type
ESP, Electric Submersible Pump
ESP is an electric submersible pump for lifting oil from deep wells efficiently.
ESP, Electric Submersible Pump
It is installed downhole to boost production when natural pressure is low.
Basic Principles and System Composition
Basic Working Principle
Principle: Electric energy on the ground is transmitted to the downhole motor through cables, driving the centrifugal pump to rotate, and boosting the well fluid to lift it to the ground.
Overall System Composition
Downhole Unit (Core): Motor, protector (protects the motor), gas-oil separator, multi-stage centrifugal pump Power Transmission: Submersible cable (high temperature and corrosion resistant) Ground Control: Transformer, variable frequency control cabinet (speed regulation and monitoring), sensor
Basic Principles and System Composition
Pump Running-in: Wellbore Preparation → Equipment Inspection → Unit Assembly → Cable Binding → Running-in → Surface Connection → Commissioning and Production Pump Pulling: Well Shutdown, Pressure Relief and Power Off → Wellhead Demolition → Unit Pulling-out → Disassembly and Inspection → Repair/Replacement
