Core Viewpoint - The article highlights the significant advancements and achievements of the Guda Oilfield's chemical flooding technology over the past 33 years, showcasing its transition from a local to a broader service provider in the oil industry [1][2]. Group 1: Technological Development - Guda Oilfield has implemented 34 chemical flooding projects since 1992, resulting in an increase of 21.47 million tons of oil, establishing itself as the largest tertiary oil recovery base in Sinopec [2]. - The facility has transitioned from relying on imported equipment and agents to achieving 100% localization, enhancing its technological capabilities [2]. - The chemical flooding stage has improved the recovery rate by 6.9%, while the natural decline rate has continuously decreased [2]. Group 2: Service Expansion - The Guda Oilfield's first external order was received five years ago, marking the beginning of its technical service expansion, which now includes eight chemical flooding projects across six oilfield units [2][3]. - The successful implementation of a chemical flooding project on the CB22F offshore platform resulted in an increase of 358 tons of oil per day and a reduction in water content by 8.7% [3]. - The latest project, a nitrogen-sealed chemical flooding service, showcases the facility's technical strength and was completed three months ahead of schedule, injecting 28,000 cubic meters of produced water into 22 wells [3]. Group 3: Knowledge Transfer and Standardization - The establishment of a comprehensive service manual covering 63 service standards has become a guideline for the processes and operations in tertiary oil recovery [5]. - The Guda team has successfully trained local technical personnel to independently conduct offshore chemical flooding projects, ensuring the sustainability of their expertise [5][6]. - The focus on providing high-quality services based on client needs reflects the company's commitment to excellence and the dissemination of its technical knowledge [6].
