Screw compressors for oil fields

I. Main Functions

Drilling mud circulation: Compressed air drives the mud flow, ensuring a smooth drilling process.

Gas injection and drainage: Provides power for oil extraction and simultaneously drains accumulated water from the well.

Oil and gas separation: Improves oil quality and production yield.

II. Typical Applications

Mobile compressors: Such as the Doosan VHP540, designed specifically for oil and gas exploration and drilling.

Deep-sea oil fields: China Shipbuilding provided screw compressors for associated gas to the "Hai Kui No. 1" FPSO, supporting deep-sea crude oil production.

III. Technological Advantages

Stable and efficient: Adapts to complex wellsite conditions, ensuring drilling safety.

Domestic breakthrough: Equipment developed by China Shipbuilding Group's 711 Institute achieves a technological breakthrough in deep-sea operations.

Exhaust compressor

Screw compressors perform exceptionally well in oil drilling applications, with the following main advantages:

I. High Reliability

Simple structure: Fewer parts, no easily damaged components, and a low failure rate.

Long lifespan: Overhaul intervals can reach 40,000-80,000 hours, suitable for long-term continuous operation.

Strong stability: Low exhaust pressure pulsation and stable output flow ensure a smooth drilling process.

II. Easy Operation and Maintenance

High degree of automation: No extensive professional training is required, and unattended operation is possible.

Low maintenance costs: Reduced human intervention lowers maintenance frequency and costs.

III. Excellent Dynamic Balance

Smooth operation: No unbalanced inertial forces, allowing the machine to operate smoothly at high speeds.

Strong adaptability: Volumetric flow rate is virtually unaffected by discharge pressure, making it suitable for various operating conditions.

IV. High Adaptability

Good media compatibility: Suitable for the compression and transportation of various gases.

Wide range of operating conditions: Applicable to various drilling environments without changing the compressor structure.

These advantages make it an indispensable piece of equipment in oil drilling, ensuring the efficiency and safety of drilling operations.
