In order to complete the annual shutdown and maintenance tasks, the company organized 8 special meetings on shutdown and maintenance, communicated with Changqing Oilfield in advance, made timely adjustments to the production of gas wells, and carefully formulated shutdown and maintenance construction plans. After receiving the advance instructions for the maintenance tasks, all departments cooperated, and personnel, materials, and equipment were quickly organized and put in place. According to the maintenance work schedule, the work progressed steadily. Based on the principle of "simultaneous advancement, close connection, orderly procedures, and quality and quantity assurance", 23 professional teams were organized, and more than 20 welding units, installation units, separator sand cleaning units, and mobile cooperation units were invested to ensure the successful completion of the maintenance tasks.
During this shutdown and maintenance, a total of 10 process modifications were completed, 41 pipelines were replaced, 72 valves were replaced or installed, 10 separators were sand cleaned, and 153 small equipment parts were repaired, providing strong support for the completion of the annual production tasks.
