摘　　要：红岗北扶余油藏是一个岩性油藏,地质特征复杂,岩性变化大、储层物性很差,是典型的特低孔低渗油气藏,剩余未动用储量难以进一步落实动用。岩石物理相能较好地反映储集层储集性能的成因特征,指导储集层的评价,为油田开发措施和油藏管理提供科学依据。采用序贯指示方法对岩石物理相控建立油藏模型。利用Petrel软件体积计算模式,可得到整个油藏的储量。由于充分考虑到了储层的非均质性,因此大大提高了计算精度。Fuyu oil reservoir in the north of Honggang is a lithologic reservoir, which is a typical ultra-low porosity and low permeability reservoir with the complex geological features,large variable lithology,and very poor reservoir properties,and the remaining unused reservoir is hard to further implement.Petrophysical facies can better reflect the genetic characteristics of reservoir properties, especially the capacity differences of different petrophysical facies,the research results of petrophysical facies can guide the reservoir evaluation and provide scientific basis of the measures for oil field development and scientific management of reservoir. Using sequential indicator simulation method stimulates lithofacies,and builds property model controlled by lithofacies.It can calculate reserves by using the volume model in Petrel.Because of taking full account of the reservoir heterogeneity, it greatly increases the computational accuracy.
