摘　　要：通过对西峰油田环县地区长8储层的矿物岩石学特征、储层储集空间类型和孔隙结构等方面进行研究,对环县地区长8储层伤害的潜在地质因素进行了详细地分析。分析结果表明,环县地区长8储层主要敏感性矿物为填隙物中的粘土矿物和碳酸盐矿物,储层酸化过程中矿物与酸反应生成的沉淀及酸化中地层释放的微粒、储层中固体微粒的迁移和入井外来流体与地层水的不配伍等是造成储层伤害的几种主要方式。Through study on mineral petrology characteristics,reservoir space types and pore structure of Chang8 reservoir of Huan county in Xifeng oilfield,potential geological factors of formation damage in Chang8 reservoir of Huan county were analyzed.The analysis results show that,the main sensitivity minerals in Chang8 reservoir of Huan county are clay mineral and carbonate mineral in interstitial materials.Several main ways to cause the reservoir damage are shedding particles caused by acidification,solid particles migration,and incompatibility between injection and formation water.
