针对安塞油田高25区块油藏的渗流为非达西流存在启动压力的特点,在室内启动压力梯度实验基础之上利用雷诺数准则判定了高25区块非均质油藏各单元对应的流体流态,并应用相渗曲线法,结合采油工程知识,确定高25井区非均质油藏合理井底流压界限,分析合理井底流压影响因素,为经济、有效地开发安塞油田提供理论指导和技术支持。
According to the characteristics of start-up pressure in non-Darcy flow in the reservoir of Block 25 of Ansai Oilfield, the Reynolds number criterion was used to determine the corresponding units of heterogeneous reservoir in Block 25 , And applying the phase-infiltration curve method and the oil production engineering knowledge to determine the reasonable bottom hole flow pressure limit of the heterogeneity reservoir in high-25 well area, analyzing the influencing factors of rational bottom hole flow pressure, in order to economically and effectively develop Ansai Oilfield Provide theoretical guidance and technical support.
