沈北高凝油驱油效率的室内实验研究

The laboratory research on displacement efficiency of Shenbei high pour point oil

高凝油在不同温度下的流动特点给油田开发带来了一系列的困难,因此,研究不同条件下高凝油驱油效率的变化规律是十分必要的.本文针对沈北高凝油,研究了温度、渗透率等因素对驱油效率的影响以及产水率的变化特征.

:The flow characteristics of high bour point oil are different at different tempera-tures. When the temperature is below the wax precipitating temperature,the high pour pointoil is non-Newtonian liquid,and its displacement efficiency is considerably reduced. So it isnecessary to study the variation law of high pour point oil with temperature. This paper hasstudied some factors,such as temperature,permeability,etc,which influence the displacementefficiency and water cut of ShenBei high pour point oil.
