We can learn from above that the study of material balance method during gas injection flooding is very important.

因此，研究注气开采过程中的物质平衡方程序具有十分重要的意义。

Gas injection flooding as an important method of EOR has been researched and applied on a large scale in both laboratory and field.

注气驱油作为提高采收率的一种重要方法，国内外已在实验室和现场进行了相当规模的研究和应用。

youdao

The general material balance equation was applied widely in the field, but few studies about material balance equation of gas injection flooding has been conducted.

常规物质平衡方程在油田已广泛应用，然而对油田注气物质平衡方程的研究较少。
