摘　　要：为改善杜 2 39断块大凌河油藏蒸汽吞吐开发效果 ,应用数值模拟技术对该块组合式吞吐进行优化研究。结果表明 :采用组合式蒸汽吞吐 ,改善了油藏温度场、压力场以及饱和度场的分布 ,提高了油藏开发效果 ,有效减缓了区块的递减趋势 ,可获得比持续蒸汽吞吐高 2 6 %的阶段采收率。同时对组合蒸汽吞吐方式、注汽速度、注汽量。In order to improve the development response of cyclic steam stimulation in Dalinghe reservoir in block Du 239, integral cyclic steam stimulation is optimized through numerical simulation. The result shows that, integral cyclic steam stimulation has improved the distribution of reservoir temperature field, pressure field and saturation field, improved development response, slowed down the decline trend, and can achieve a stage recovery factor 2.6% higher than that of continuous cyclic steam stimulation. Also optimized are the mode, injection rate, shut-in time an scale of the integral stimulation.
