A viscosity - temperature model of cumulative steam injection rate and cumulative oil production has been established for cyclic steam stimulation stage according to the standard viscosity - temperature curve of american material experiment society 摘要根据美国材料试验学会制定的标准粘温关系曲线,建立蒸汽吞吐阶段累计注汽量与累计产油量之间的粘温模型。
