Operational Status of Well 146 at the Yanchang Xingzichuan Oil Production Plant:
1. Significant Equipment Advantages: The unit features a compact design—reducing overall volume by 88% and footprint by 81%—while being 88% lighter, which greatly facilitates installation.
2. Convenient and Efficient Maintenance: The equipment at Well 146 is mounted on a movable support frame. During well workovers or pump inspections, the hydraulic cylinder support can simply be shifted aside, making maintenance tasks both convenient and efficient.
3. Enhanced Safety and Environmental Protection: The unit is a fully enclosed, skid-mounted hydraulic system, which minimizes the risk of mechanical injury and reduces the need for high-altitude operations. It includes an automated alarm and emergency shutdown system that triggers based on real-time operating conditions, ensuring both equipment and personnel safety. Furthermore, the hydraulic cylinders utilize proprietary sealing technology to effectively prevent the leakage of oil or gas, thereby minimizing environmental pollution.
4. Notable Energy Efficiency: The system is more energy-efficient than traditional beam-pumping units, offering an energy savings rate of approximately 40%.
5. Dynamic, Digitally-Integrated Field Management: The equipment supports intelligent operation and control, organized into a multi-tiered management structure. The smart control platform operates across three levels—the operational zone, the oil production plant, and the oilfield company—with distinct management permissions at each tier, enabling real-time, dynamic oversight.
6. High Operational Efficiency: The equipment can operate on a single-well basis. In a "one-to-two" configuration (where one unit serves two wells), if one well requires a workover or pump inspection, the system can switch to single-well mode, allowing the other well to continue production and thereby maintaining overall operational efficiency.
