剩余油形成机理与赋存状态研究综述

Remaining Oil Forming Mechanism of Occurrence Research

随着油田注水开发的不断深入,储层孔隙空间内的油水饱和度随之不断地发生变化,剩余油的形成和赋存状态趋于复杂化,并在一定程度影响驱油效率。认识剩余油的形成机理和赋存状态,对下一步研究剩余油的分布和挖潜提供依据。因此,文章从剩余油的形成机理和赋存状态两个方面进行了研究综述,并对剩余油的赋存状态重新进行划分。

The saturation of oil water in interspace has been changing as a result of continued developing of injection oilfield recovery.The producing and keeping of the rest of oil become complicated and this has some effects in efficiency of using oil.Learning how the rest of oil produced and kept can provides a right way to research where can find it and how to exploit it.Therefore,the paper describes something about the producing and keeping of the oil and redefines the forming of the rest oil.
