摘要
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。
The seepage of Gao-25 block in Ansai oilfield is non-Darcy flow,so it has a characteristic that oil reservoir exists actuating pressure.Each unit corresponding fluid condition of Chang-10 heterogeneity reservoir in Gao-25 well block was determined by using Reynolds number criterion based on start-up pressure gradient of indoor experiment.Then,the IPR curve on different flow patterns was set up combined with production engineering knowledge and parameters of relative permeability curve,influencing factors of bottom-hole flowing pressure was analyzed,which can provide theoretical guidance and technical support to develop low permeable oilfield economically and effectively.
