Screw Pump for Coalbed Methane Applications
For high-rank CBM, maximizing methane output and ensuring long-term performance, the straight-to-ground drive screw pump is optimized for high-rank CBM production. This system considers the constraints of the CBM well system and ensures coordination between the pump and well conditions.
Screw Pump System Overview
The screw pump system includes a Surface Drive Device, Downhole Screw Pump, Electrical Control Panel, and Matching Tools. Widely used in oil fields both domestically and internationally, screw pumps play a vital role in oil production. There is a growing trend to replace large heavy pumping units in shallow and medium-deep wells with screw pumps.
Applicable Oil Conditions
Screw pumps are suitable for low-viscosity crude oil as well as heavy oil, high-freezing-point oil, high-wax oil, high-sand oil, and high-gas oil. They offer advantages such as low initial investment, high oil production efficiency, low energy consumption, simple structure, and ease of operation, installation, and maintenance.
Key Advantages
Screw pumps are known for their low initial cost, high oil production efficiency, energy savings, simple design, and ease of use. They are ideal for various oil types and environments.
