摘　　要：原油体积系数在容积法储量计算公式中处于分母,体积系数的微小差异将带来储量计算结果的几何级差异。体积系数的第一手资料一般来自高压物性分析,油区开发进入中后期,许多区块已不满足高压物性取样和分析的条件。目前,相对于储量计算中其他参数而言,对原油体积系数的研究甚少。基于矛盾论的哲学思想,探讨了胜利油区原油体积系数的影响因素,在此基础上提出了运用试油资料求取原油体积系数的几种方法,并给出了各方法的局限性和注意事项。The crude oil volume factor is a denominator in the reserve calculation formula of the volumetric method.A micro difference of the number will lead to the geometric difference of the calculating result of reserve.The firsthand information of volume factor often comes from the PVT analysis.But in the mid-and-late developing stage,many blocks are no longer satisfied for PVT sampling and analysis.It is very important to obtain methods for the parameters based on oil-testing materials.In terms of other reserve parameters,the research on volume factor is fewer.Based on the contradiction thinking in philosophy,this article probes into the influencing factors,and advances a few methods.Besides,this article gives the limitations and precautions of these methods.
