华北油田稠油油藏采收率计算方法综述

A Review on Huabei Oil Field Heavy Oil Reservoir Calculation Methods of Recovery Factor

本文通过对油藏水驱采收率的计算方法:水驱曲线法、油水粘度比法、童氏图版法、波及系数矫正法等进行了归类对比分析,针对华北油田稠油油藏水驱采收率计算的基本原理和适用条件,形成了适合计算华北稠油油藏水驱原油采收率方法,优选出目前较为适合的的原油采收率计算方法,回归得到研究区块的采收率计算公式,计算得到了华北油田某普通稠油油藏原油采收率。

In order to calculate the water flooding oil recovery method:water flooding curve method,oil-water viscosity ratio method,Tong's chart method,sweep coefficient correction method.This article in view of the above methods are classified and comparative analysis.Established for the calculation of Huabei Oil Field e heavy oil reservoir water flooding oil recovery method,on the basis of Huabei Oil Field heavy oil reservoir water drive recovery factor calculation of the basic principles and conditions.It?s selected the suitable oil recovery ratio calculation method in this paper,Regression to obtain oil recovery rate calculation formula,at last A common heavy oil reservoir in Huabei Oil Field as an example,calculated its oil recovery.
