摘要
海洋石油工业具有高技术、高投入、高风险"三高"特点,这决定了在海洋油气资源勘探开采过程中必须要不断进行理论技术创新和实践,实现海洋油气资源的高效、安全合理开发利用。中国海油以国家科技重大专项为依托,"产学研用"相结合,通过联合攻关,在海洋油气勘探、开发、钻采、工程建设等方面取得了丰硕的理论认识创新、技术进步和实践成果。建立并完善了中国近海深层湖相烃源岩大规模生气和成藏理论、近海高温高压天然气成藏理论、近海新近系岩性油气藏成藏理论、盆地边缘富烃凹陷形成机制地质认识,形成了适用于近海独特地质条件的高效地震勘探配套技术,推动了中国海域渤中19-6、垦利6-1、惠州26-6等26个大中型油气田的发现;形成并丰富了海上常规稠油水驱综合调整及高效开发钻采技术、非常规稠油多轮次吞吐与规模化热采配套技术、海上油田化学驱技术,大幅提高了海上油田开发采油速度和采收率;攻克海上高温高压钻井难题,促成中国海上最大高温高压气田东方13-2成功投产;形成了具有自主知识产权的深水油气开发工程技术体系及深水工程实验技术体系,建成流花油田群示范工程,自主设计建造了世界首个带凝析油储存功能的深水半潜式平台"深海一号"。以部分典型案例为代表,论述国家科技重大专项成果为中国海油增储上产起到了支撑作用。
The offshore oil industry is characterized by high technology,high investment and high risks.Therefore,it is necessary to continually innovate the theories and technology in offshore oil and gas exploration and development to bring about high-effective,safe and reasonable development and utilization of offshore oil and gas resources.Based on the national science and technology major project and combination of production,universities and research,CNOOC has made the joint research efforts and achieved fruitful results in theoretical innovation and technological upgrading and application in the areas of offshore oil and gas exploration,development,drilling,and engineering construction.It has established and perfected the theory on large-scale gas sourcing and accumulations of lacustrine source rock in China’s offshore deep layers,the offshore high-temperature and high-pressure natural gas accumulations theory,the accumulations theory of offshore Neogene lithological oil and gas reservoirs,and the geological theory on the formation mechanism of hydrocarbon-enriched depressions on the periphery of basin.CNOOC has also developed a system of high-effective seismic exploration technologies suitable for the unique offshore geological conditions,leading to discoveries of 26 large and middle-size oil and gas fields off China’s sea areas,such as Bozhong 19-6,Kenli 6-1 and Huizhou 26-6.A series of technologies have been developed and enriched to substantially improve production speed and productivity of offshore oilfields,such as the drilling technology for integrated water-flooding adjustment and high-efficiency development of offshore conventional heavy oil,the systematic technology for multiple huff and puff thermal production of non-conventional heavy oil,and the chemical flooding technology of offshore oilfields.CNOOC also overcame the offshore high-temperature and high-pressure drilling bottlenecks,thus putting Dongfang 13-2 into production,the largest offshore high-temperature and high-pressure gas field in China.It has developed the deepwater oil and gas development engineering technological system and the deepwater engineering experiment technological system with its own independent intellectual property rights and constructed the demonstrative project of Liuhua oilfield group.In addition,CNOOC has independently designed and built the world’s first deepwater semi-submarine platform with the storing function for condensate oil-Shenhai-1.With some typical cases,the achievements from national science and technology major project supported CNOOC for increase of its offshore reserves and production.
