摘　　要：针对油藏工程方案优化过程中无法考虑各种因素之间的交互作用问题,在单10块蒸汽泡沫驱方案优化设计 中尝试采用均匀设计方法取代优选法,选取注氮时机、气水比、表面活性剂浓度和注采比四项参数,每项参数设计 了五个水平,共设计了12个数值模拟对比方案,研究了各参数对净产油量的影响。实际应用证明,该方法可以在 减少计算工作量的同时提高计算精度,具有较大的推广价值。For the mutual affection of all kinds of factors cannot be considered during the reservior engineering project optimization, the method of 'uniform design' has been adopted instead of the optimized method in the steam -foam flooding project optimization design in block San 10. Four parameters were chosen, namely the nitrogen injection timing, gas -water ratio, the surfactant con -centration and the injection-production ratio, five levels of every parameter and twelve numerical simulation correlation projects were designed for studying the effect of every parameter on the net oil production. The practical application indicates that the method can not only decrease the workload of calculation, but also improve the precision of calculation, which has great popularized value.
