Screw Pump for Coalbed Methane Application
For high-rank CBM, the goal is to extend the lifespan and maximize methane production. This involves optimizing the performance of straight-to-ground drive screw pumps in high-rank CBM systems. The pump must be coordinated with well conditions and actual constraints.
Screw Pump System Overview
The screw pump system consists of a Surface Drive Device, Downhole Screw Pump, Electrical Control Panel, and Matching Tools. These pumps are widely used in oil fields both domestically and internationally, playing a crucial role in oil production. There's a growing trend to replace large heavy pumping units in shallow and medium-deep wells.
Applicable Oil Conditions
Screw pumps can handle 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.
Advantages
Screw pumps provide cost-effective solutions with high efficiency, low power usage, and easy maintenance. Their design allows for smooth operation even in challenging environments.
