| 摘 要： | 对于低渗透油井,合理的井底流压是保持低渗高气油比油井稳产、高产的关键.通过分析低渗油藏油气水三相流动的流入动态,并利用拟合系数和油井完善系数对其修正,结合低渗岩石的压力敏感性,利用油井具体动、静态参数给出了低渗高气油比油井合理井底流压确定的过程.现场实例计算结果表明,低渗油藏三相流入特征修正法充分考虑了低渗高气油比油井的特点和地层参数随压力变化特征,能够准确确定油井的合理流压,具有适应性广、精度高的特点.

| Abstract: | To low permeability oil wells,proper bottom-hole fluid pressure is a key to the high and stable yield of the wells.The steps for determining the proper bottom-hole fluid pressure of the wells are proposed.Firstly,the liquid yield of the well is calculated according to the inflow performance of oil-gas-water three-phase flow at well bottom.And then,it is modified by fitting coefficient and oil-well perfect coefficient.Lastly,the proper bottom-hole fluid pressure is determined by means of the static and dynam... |
