摘　　要：通过对志丹油田岩性特征、物性特征、填隙物特征、孔隙结构以及地层流体进行了分析,探讨了引起志丹油田长2储层伤害的地质因素。研究认为,酸敏是引起储层伤害的主要地质因素,速敏、水敏也能引起一定程度的损害。建议在开采过程中加入铁离子稳定剂,控制注入水的水质标准,以减弱或者预防储层伤害。The main geological factors are studied, related to injury of Chang 2 reservior during exploration and development, based on analysis of lithology, physical properties, pore-filling mineral composition, pore structure and formation fluid. Acid sensitivity are the main factors causes injury of Chang 2 reservior, water sensitivity and velocity is minor factor. So some suggestion are put forward to avoid to injury the reservior, such as control the quality of water, injection of Fe^3＋ stabilizing.
