摘要
矿场实验数据表明,在井底流压高于饱和压力(Pf >Pb)条件下,油藏的渗流特征表现为单相达西流,当井底流压低于饱和压力(Pf<Pb)时,油藏受热动力影响较大,渗流表现为油气两相渗流.基于上述渗流理论基础,对西39-25井的普通黑油油藏和张18-28井挥发性油藏的系统试井资料进行了解释,确定出油井合理工作制度.
Laboratory testing dates show: in the conditions of the bottom hold flowing pressure higher than saturating pressure, flowing character of reservoir takes on single phase-Darcy flow, on the contrary more thermodynamic effect changes reservoir flow into gas-oil-phase flow. Based on the flowing theory, analyzed and interpreted static-well-test dates of well x39-25 in black oil reservoir and Zhang 18-28 in volatile reservoir, determined the proper nozzle of oil well.
