摘　　要：在大庆朝阳沟油田蒸汽驱试验区地质研究基础上,利用CMG软件中的STARS模块进行蒸汽驱参数优选,并对不同蒸汽驱开发方案的开发指标进行了预测。结果表明,蒸汽驱注汽速度应不小于50 t/d,由于低渗透油藏要求高注采比,注汽速度可以提高至70 t/d。井底蒸汽的干度越高,开发效果越好;连续蒸汽驱开发效果较好;连续蒸汽驱5 a转为常规水驱开发效果与连续注蒸汽驱开发效果相当。This paper studies the geology of steam flooding pilot area in Daqing Chaoyanggou Oilfield,optimizes steam flooding parameters by using STARS module of CMG software,and predicts development indices of different steam flooding schemes.The result indicates that steam injection rate shall not be less than 50t/d.Because low permeability reservoir requires high injection-production ratio,steam injection rate can be improved to 70t/d.The higher the bottom hole steam quality is,the better the development response will be achieved;continuous steam flooding has good development response;the development response of converting to water flooding after 5 years of continuous steam flooding is equivalent to that of continuous steam flooding.
