摘要在国内外蒸汽驱调研的基础上，以国内某油田区块单个井组为例，采用数值试验方法进行水平井蒸汽驱注采参数优化研究，随后对整个区块进行水平井蒸汽驱方案预测。研究表明：最优注采参数为，水平生产井布在距油层底部1/4油层厚度处，垂直注汽井射孔位置为在距油层底部20%～25%油层厚度处，每口水平生产井的注汽井数为4口，水平井水平段长度应取300 m，井排距为140 m；整个区块内，采用水平井蒸汽驱技术最终可提高采收率12%以上，该结果可为实际区块实行水平井蒸汽驱开采方案实施提供技术支持，为其他同类型油藏的开采提供借鉴。

Abstract：On the basis of literature investigation about steamflooding，the numerical simulation method is used to optimize the injection-production parameters of steamflooding with vertical injector and horizontal producer，subsequently，the development performance of steamflooding with horizontal wells of the entire block is forecasted. The results indicate，the best production conditions are：the horizontal producer should be located closely to the bottom of the reservoir，the vertical injector should be perforated with a distance of 20%–25% thickness to the bottom，each horizontal producer should allocated with 4 injectors，the length of the horizontal well should be 300 m，the distance between horizontal wells should be 140 m. The recovery factor will be enhanced by above 12% by using steam driving with horizontal wells. The results can be employed to guide the spot execution of steamflooding with horizontal wells.

Key words： numerical simulation horizontal well steamflooding multi-field coupling
