On April 6th, the spring maintenance work for the 10kV power lines in the Huanjiang oil production area of the Longdong operation zone, managed by Changqing Oilfield, was successfully completed following the final inspection task on the Fucheng 10kV #116 line.
The project department for clean power development at Changqing Oilfield implemented detailed measures to ensure the maintenance proceeded smoothly. Through systematic preparation and comprehensive control of all elements, the department effectively advanced the electrical maintenance campaign. The Huanjiang Power Brigade, responsible for the maintenance tasks, concentrated its efforts by enhancing staff skill training and testing to improve practical operational capabilities. It conducted strict verification of contractor qualifications, personnel allocation, and safety measures to mitigate operational risks. A full calibration of safety tools and a meticulous inspection of key components of maintenance vehicles—such as brakes, tires, and lighting systems—were carried out to eliminate potential hazards. The brigade maintained strict control over personnel, equipment, and vehicles throughout the entire process to ensure the orderly progress of the maintenance work.
On-site supervision was significantly strengthened. The project department utilized technological tools including mobile terminals, surveillance devices, and drones to establish an all-encompassing, multi-level monitoring system. This approach enabled precise management of safety risks during the maintenance period. Party members and leading cadres from the Huanjiang Power Brigade took the initiative to work at the maintenance sites, taking the lead in safety oversight, identifying on-site risks, and controlling the quality of repairs. They conducted full-track inspections of critical maintenance sections and high-risk operations. Technical personnel provided continuous supervision in accordance with operational guidelines, ensuring that technical standards and procedural norms were strictly followed. This rigorous approach to quality control and accountability for repair standards was reinforced through frontline command, technical empowerment, and round-the-clock supervision, providing a solid foundation for the safety and quality of the maintenance operations.
Skill development was further deepened through targeted training initiatives. The project department focused on enhancing employee competencies to improve the efficiency and quality of the maintenance work. The Huanjiang Power Brigade widely promoted mentorship programs and one-on-one coaching, using on-site explanations, demonstration drills, and simulated practical exercises to help staff improve their operational skills and problem-solving abilities in real-world conditions. At the Huanbei maintenance site, the brigade organized emergency drills for fall-from-height accidents involving maintenance teams from Gengwan, Mubo, and Fanjiachuan. These exercises refined emergency response procedures and on-site handling measures, improving rescue readiness. By integrating competition into learning and using drills to simulate actual scenarios, the training outcomes were effectively translated into practical performance, ensuring the high quality and effectiveness of the spring maintenance.
According to statistics, the spring maintenance in the Huanjiang oil area lasted 22 days. During this period, a total of 20 10kV power lines, spanning 1,367.958 kilometers, were inspected and repaired. The work addressed 614 defects, replaced 1,240 pieces of equipment, and installed 164 vibration dampers. These efforts comprehensively eliminated potential risks in the power grid equipment of the oil production area, providing a reliable electricity supply to support increased crude oil production in the Huanjiang region.
