The Modular Wellhead Package (MWP) is the most typical definition in the industry — a skid-mounted wellsite equipment unit that integrates all facilities from the wellhead Christmas Tree to the main process pipeline leading to the gathering station.
Working Principle: Factory Prefabrication + Rapid On-site Installation
The core concept is to transform on-site construction into factory manufacturing:
1. Factory Prefabrication — Equipment, piping, and instrumentation are pre-assembled, welded, and tested in the workshop per the process drawings, ensuring more controllable quality.
2. Integral Transportation — The skid body is transported to the wellsite as a single, integral piece of specialized equipment.
3. On-site Positioning — It is lifted into place on the pre-cast foundation; once the inlet and outlet pipelines and power supply are connected, it is ready for commissioning.
4. Intelligent Monitoring — A PLC/DCS system combined with RTU remote terminals and solar power enables unmanned operation and remote data transmission.
Compared with traditional on-site assembly, the MWP reduces on-site installation workload by approximately 80%, shortens the construction period by approximately 60%, and lowers total investment by 15–30%.
Applications
Suitable for the routine production control of gas wells, oil wells, and injection wells, providing a standardized, replicable integrated solution.
