Core Viewpoint - The successful full production of the Liuhua oil field's secondary development project marks a significant advancement in China's deepwater oilfield development capabilities, achieving a daily crude oil output of 3,900 tons and setting a new production capacity record [1][3]. Group 1: Project Overview - The Liuhua oil field, China's first deepwater oil field, has fully commenced its secondary development project, consisting of 32 production wells, with an expected annual output exceeding 1 million tons next year [1]. - The project is located approximately 240 kilometers southeast of Shenzhen, utilizing the "Haiji No. 2" deepwater jacket platform and includes a subsea production system and a cylindrical offshore oil and gas processing plant [1][3]. - Since the first production wells were put into operation in September of last year, the cumulative crude oil production has surpassed 900,000 tons [1]. Group 2: Technological Innovations - The "Haiji No. 2" platform incorporates 15 globally leading technologies and features a highly integrated digital twin system that optimizes maintenance strategies and reduces operational costs [9]. - The platform is designed for deepwater operations, standing at 428 meters tall and weighing over 50,000 tons, making it the highest and heaviest offshore oil production platform in Asia [9]. - The project has successfully implemented a set of stable oil control and water management technologies, significantly improving the oil recovery rate and extending the operational lifespan of the oil field by 30 years [14]. Group 3: Industry Significance - The development of the Liuhua oil field represents a breakthrough in addressing the challenges of deepwater reef limestone oil reservoir extraction, which is recognized as a global technical difficulty [5][12]. - China's deepwater oil and gas exploration and development capabilities have made historic progress, with the country becoming one of the few able to independently conduct deepwater oil and gas exploration [15]. - The deepwater oil and gas production capacity has exceeded 12 million tons of oil equivalent, contributing significantly to national energy security [19].
