【摘要】 从辽河油区的地质条件和开发特征出发，立足单因素分析，在着重研究渗透率、净总厚度比和单层厚度对原油采收率影响的基础上，利用《价值工程》中的“功能重要度评价法”，优化出不同类型稠油油藏蒸汽吞吐和蒸汽驱开发阶段的采收率计算公式。经实际资料验证，该公式对油田开发前期确定采收率和可采储量，具有较好的适用性。更多还原

【Abstract】 According to the geologic conditions and development characteristics of Liaohe oil zone,on the basis of emphatically studies of the effect of permeability,the ratio of net gross thickness and single zone thickness on oil recovery factor and through the single factor analysis,this paper optimizes the recovery factor calculation equation suitable for the stages of steam stimulation and steam drive of different types of heavy oil reservoirs using “the method of function importance evaluation” in the“Value Project”.Practical data confirmed that this equation is fairly applicable for determining recovery factor and recoverable reserves in the early development stage of oilfield .更多还原
