结合陆地稠油热采技术，研究了适合我国海洋稠油热采的方式。认为海洋稠油热采开发评价指标应该包括平台生产寿命周期、平台空间分布、热利用率、注采井网、注汽时机及方式转变、热采经济性等。对于海洋常规稠油热采可依次选用蒸汽驱、汽水交替注入与热水驱等热采方式，可以采用反七点或反九点井网，使得在平台安全生产期内采收率高，经济效益好。
結閤陸地稠油熱採技術，研究瞭適閤我國海洋稠油熱採的方式。認為海洋稠油熱採開髮評價指標應該包括平檯生產壽命週期、平檯空間分佈、熱利用率、註採井網、註汽時機及方式轉變、熱採經濟性等。對于海洋常規稠油熱採可依次選用蒸汽驅、汽水交替註入與熱水驅等熱採方式，可以採用反七點或反九點井網，使得在平檯安全生產期內採收率高，經濟效益好。

Combined with onshore heavy oil thermal recovery technique, research was conducted on the methods applicable to do-mestic offshore oil thermal recovery. It is deemed that the evaluation indexes of offshore heavy oil thermal recovery should include platform longevity, platform space distribution, heat utilization efficiency, injection/production patterns, steam flooding timing and methods convertion, economic performance of thermal recovery and so on. If possible, steamflood, alternating injection of steam and water, and hot water flooding can be successively applied in offshore conventional heavy oil thermal recovery. In addition, the appli-cation of inverted seven-spot or inverted nine-spot well pattern can improve recovery ratio and economic returns of the platform in safe production period.
