摘要: 油藏水驱油效率低,为驱难动用储量。通过室内实验,研究该井区注空气开发的可行性。结果得出注空气能够提高驱油效率。当注入 15 个 PV 时,空气驱油效率为 57.14%,而水驱只有 34.95%。通过细长管空气驱低温氧化实验和燃烧管空气驱高温氧化实验,发现驱替过程中氧气被大量消耗,发生了低温氧化,贝尔油田希 11-72 井区南二段油层可以采取注空气驱。

Abstract: The water displacement efficiency in Beir Oilfield is low, especially the ultra-low permeable reservoir in Xi 11-72 well field. The paper studies the feasibility of air injection in the well field by bench scale experimental study, and draws the conclusion that the displacement efficiency could be advanced by air injection. The displacement efficiency of air injection can reach 57.14% when injecting 15 PV, while the water displacement efficiency is 34.95%. In slim line low-temperature oxidation experimentation and combustion tube high temperature oxidation experimentation, oxygen is exhausted in large quantities and low-temperature oxidation occurs. So the method of air injection can be adopted in the reservoir of Xi 11-72 Well Field of Beir Oilfield.

Key words: Beir Oilfield, air injection, enhance recovery, oxidation experimentation
