What are the advantages of electric submersible pumps?

1、Strong displacement and lifting capacity

1. Large displacement range

Small displacement can meet the needs of low yield wells, while large displacement can produce thousands to tens of thousands of cubic meters of liquid per day, suitable for high-yield oil wells, high water content wells, and late stage water injection development wells.

2. High lift and deep lifting

The multi-stage impeller series structure can easily achieve a lifting depth of 2000-4000m, meeting the needs of deep and ultra deep well mining.

3. Wide range of liquid volume adjustment

The ground frequency converter can continuously adjust the speed, achieve stepless production adjustment, and adapt to changes in oil well production capacity.

2、Outstanding ability to adapt to complex well conditions

1. Suitable for inclined wells, directional wells, and horizontal wells

Without a sucker rod, there will be no eccentric wear of the rod and pipe, making it the preferred lifting method for high angle and horizontal wells.

2. Resistant to high water content and high liquid volume

It has strong adaptability to high water content wells and will not experience a sudden drop in efficiency due to large liquid volume like a sucker rod pump.

3. Can be used in offshore oil fields

Underground installation and small ground footprint make it suitable for environments with limited space on offshore platforms.

4. Adapt to high gas to oil ratio wells

Can be paired with gas processing modules, anti air pumps, suction chambers, etc. to reduce the impact of air locks.

5. Can extract heavy oil and waxy crude oil

Combined with electric heating, viscosity reduction device, and large channel impeller, heavy oil and high pour point oil can be extracted.

3、High operational efficiency and good energy consumption performance

1. High hydraulic efficiency

The multi-stage centrifugal pump structure has low hydraulic loss and overall lifting efficiency generally higher than conventional rod pumps.

2. The energy-saving effect of frequency conversion is significant

Adjust the displacement as needed to avoid large horses pulling small cars, with an energy-saving rate of up to 10% to 30%.

3. High power density

The underground motor has a small volume and high power, and can achieve high-power lifting in limited casing space.

4、Stable operation and long lifespan

1. Long continuous operation cycle

Under normal operating conditions, it can operate continuously for 1-3 years, reducing frequent operations.

2. Simple ground equipment with low failure rate

No moving parts such as pumping unit, gearbox, four-bar linkage, etc., resulting in minimal ground maintenance.

3. Good resistance to vibration and impact

The overall sealing structure underground operates smoothly and is not easily damaged.

5、High degree of automation and intelligence

1. Can achieve remote monitoring and control

Equipped with downhole pressure, temperature, leakage, and vibration sensors for real-time monitoring of working conditions.

2. Complete automatic protection function

It has multiple protections such as overload, underload, overheating, phase loss, and short circuit.

3. Easy to implement digital oilfield management

Can be connected to SCADA and IoT platforms to achieve unmanned and centralized control.

6、Installation and management advantages

1. Small footprint

Only a ground control cabinet and junction box are needed, especially suitable for cluster wells, encrypted wells, and urban wells.

2. Low noise and environmentally friendly

No reciprocating noise from the pumping unit, which is more in line with environmental protection and residential requirements.

3. The homework is relatively simple

The entire task can be completed in one go, which is faster than checking the pump.

7、Strong process scalability

1. Can be matched with various underground tools

Such as sand control, filtration, multi-point monitoring, dilution, heating, etc., it has strong adaptability.

2. Can be used for water injection wells, drainage and gas production wells

Not only for oil extraction, but also for drainage and gas production, backwashing of injection wells, groundwater discharge and other scenarios.

3. Multiple units can be connected in series or parallel

Meet the special needs of ultra-high head and ultra large displacement.

8、Economic and Management Value

1. Significant increase in single well production

Especially for middle and high-yield wells, the effect of increasing production is significant.

2. Reduce the frequency of well repair operations

Long cycle operation reduces job costs and downtime losses.

3. Easy to deploy on a large scale

Suitable for unified supporting and operation of large oil fields, with lower management costs.
