通过对陕北安塞油田长。储层的岩性、物性、孔隙结构、填隙物成分及地层流体性质的分析和研究，探讨了油田勘探开发过程中引起长。储层潜在性伤害的主要地质因素，认为砂岩中的敏感性矿物，尤其是酸敏性矿物是导致长。储层伤害的主要原因，孔隙结构及流体性质也可引起一定程度的储层伤害。在油田开发过程中，建议通过控制注入水的水质标准，或向地层中注人粘土稳定剂、铁离子稳定剂等方法来预防或减轻可能出现的储层伤害。 Through the Ansai Oilfield in northern Shaanxi. Reservoir lithology, physical properties, pore structure, interstitial composition and formation fluid properties of the analysis and research to explore the oil exploration and development process caused by long. The main geologic factors underlying reservoir potential damage suggest that the sensitive minerals in sandstones, especially acid sensitive minerals, are responsible for long formation. The main reason for reservoir damage, pore structure and fluid properties can also cause some reservoir damage. In the process of oilfield development, it is suggested to prevent or mitigate possible reservoir damage by controlling water quality standards for injected water, or injecting clay stratum and iron ion stabilizer into the formation.
