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。

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.
