摘要

在油水两相中

流体渗流服从达西定律

由此可以建立流动单元的生产压差计算公式。流动单元主要依据储层的渗透率、孔隙半径和岩性特征来进行。双河油田可划分为4种不同的流动单元。计算结果表明:双河油田不同流动单元的理论压差值与实测值吻合。

Abstract

In oil and water phases

fluid percolation obeys Darcy's law.According to this

the formula for calculating producing pressure differences of the interwell fluid units could be established.The fluid units could be classified according to the pore radius

permeability and petrophysical property of a reservoir.The fluid units in Shuanghe Oilfields could be divided in to 4 different types.Calculated results suggest that the theoretical pressure differences of different flow units in Shuanghe Oiffields fitted well to the measured pressure differences.
