摘　　要：为了快速评价或优选原油产能建设项目,采用统计分析方法,深入剖析2007—2015年中国石化新区产能建设项目,得到了普通稠油、热采稠油、一般低渗透、特低渗透、一般断块、复杂断块、缝洞型碳酸盐岩和海上等8类油藏影响开发方案油藏工程关键参数设计的主控因素,包括油藏类型、地质储量、含油面积、油藏埋深、渗透率和原油黏度等,建立了对应8类油藏的油藏参数与单井产能开发指标的评价模型。针对2016—2017年新区部署实例,应用8类油藏模型,快速评价106个产能建设单元的日产油能力,结果表明,快速评价模型对产能优选具有较好的预判性。通过模型应用,发现在应用前必须注意合理的适用范围,否则存在较大误差;在应用中,油藏平均参数选取必须谨慎,否则也将导致较大的误差。In order to rapidly evaluate or select oil productivity development projects,statistical analysis method was applied to thoroughly analyze the productivity development projects of new blocks,SINOPEC in 2007-2015. The main control factors of key reservoir engineering parameters influencing the development plans design were obtained for eight types of reservoirs including common heavy oil reservoirs,thermal recovery heavy oil reservoirs,low-permeability reservoirs,ultralow permeability reservoirs,fault-block reservoirs,complex fault-block reservoirs,fractured-vuggy carbonate reservoirs, and offshore reservoirs. These factors include reservoir type,geological reserves,oil-bearing area,reservoir depth,permeability,and oil viscosity,etc. Statistic models of reservoir parameters in eight types of reservoirs and productivity development indexes of single well were proposed as well. Daily oil production capacity of 106 productivity development units was evaluated rapidly according to the new deployed development blocks in 2016-2017 with 8 reservoir models. The results show that the rapid evaluation model can be used to judge the selection of productivity. The application of the model indicates that the reasonable application range should be known before the application and reservoir parameters should be selected carefully during the application to keep away to produce large errors.
