从储层特征出发, 分析了南翼山浅层Ⅰ+Ⅱ油层组储层产生伤害的原因, 指出由于岩性和物性的复杂性, 导致储层容易被损害。敏感性分析表明, 储层主要的伤害类型是水敏、盐敏和酸敏伤害, 其次是速敏伤害。在勘探开发中应把防止水敏、盐敏和酸敏伤害作为优先考虑的问题。

Based on the reservoir characteristics analysis of Nanyishan Ⅰ＋Ⅱ shallow reservoirs, this paper analyzes the damage mechanism of the formation. Due to the complexities of physical properties and minerals, the reservoir tends to be damaged. The sensitivity analysis indicates that the reservoir is mainly water sensitivity, salt sensitivity and acid sensitivity, but minor velocity sensitivity. So preventing water sensitivity, salt sensitivity and acid sensitivity during the exploration and exploitation of the reservoir should be taken into consideration first.
