Product Introduction 

    The wellsite gas production (metering) skid is mainly installed at the wellhead of the gas well, which has the functions of pressure control and flow control, production regulation, emergency cutoff, continuous metering of single well, etc., applicable to the standardized construction of the wellsite. The product adopts highly integrated and functional modular design, which can effectively reduce the site construction cost, construction period and floor area, improve the quality of equipment design and production, and effectively realize the fine and standardized management of equipment.

   In order to meet the application and transportation requirements of single well and cluster well pad, the well pad gas production (metering) skid is mainly divided into 1 ~ 3 well pad gas production (metering) skids, and more than 3 well pad gas production (metering) skids combined.

   The equipment has significant advantages in installation, migration, floor space, function integration, safety performance, automation control, investment saving, environmental protection and energy saving, and is suitable for a variety of scenarios and industries.

 Application Cases 

The wellsite gas production (metering) skid has been promoted and applied in units such as China United Coalbed Methane, Yanchang Gas Field, and Changqing Oilfield. Through field applications, the modular and integrated design has reduced the average engineering footprint by 30%. Assembly and debugging are carried out in the factory, and on-site work only requires connecting pipeline interfaces and external electrical connections, which can shorten the construction period by 50%. Additionally, the skid structure facilitates overall relocation, enhancing equipment utilization and rapid deployment capabilities.
