摘　　要：随着中油股份公司海外成功上市及WTO的加入,我国储量评估工作与国际通用标准接轨已势在必行。在不增加勘探工作量的前提下,尽可能使油气田可采储量计算更加接近客观实际。本次研究在收集辽河油区已开发油田182个开发单元的静、动态资料的基础上,对影响采收率的因素进行了分析,采用多元回归方法,得出了适合辽河油区勘探阶段的采收率经验公式,为勘探阶段采收率的标定提供了依据。该公式适用性较好,有一定的推广应用价值。It is imperative to conduct the reserve evaluation combined with general internal standard with the entry into WTO and PetroChina Stock Company successfully coming into the market.Therefore,it is necessary to select the parameters carefully in recoverable reserve calculation,and fully study and summarize the calculation methods.Without increase in exploration workload,we try to make the calculation of oil and gas field recoverable reserve more closed to the objective and actual condition.Based on the collected static and dynamic data from 182 development units in the developed oilfields in Liaohe oil province,this paper analyzes the factors that influence recovery factor,and sets up mathematics models by adopting multiple regression and grey theory analysis.Through analysis and screening,the recovery factor analogy standard sequence and empirical equation that fit for different kinds of reservoir types in Liaohe oil province are obtained,which can provide a basis for recovery factor calibration at exploration stage.This equation is of good applicability and has certain spread and application value.
