摘　　要：为有效地挖掘油田剩余油潜力,改善开发效果,大庆油田首次在葡北油田稀油油藏进行了蒸汽驱开采提高采收率的研究。在数值模拟研究的基础上,综合分析了蒸汽驱的各种影响因素,优选了注采参数,优化了注汽方案,并通过现场试验评价了蒸汽驱开发效果。试验研究结果表明:蒸汽驱是水驱油藏的有效补充,通过增加可采储量,实现了蒸汽驱和水驱的优势互补,提高了油田采收率,取得了较好的开发效果。In order to improve development results, pilot research on steam drive in thin oil reservoirs are executed in No.7 Oil Production Company for the first time. Based on digital simulation, this paper analyzes many effective factors on steam drive. Injection-production parameters and steam injection plan are optimized, and the development results are evaluated according to field tests. The testing results suggest: Steam drive can be the effective complementary technology of water flooding; Recoverable reserves can be improved; Due to the dominant complementation of steam drive and water flooding, the oil recovery factor will be improved and good development results can be achieved.
