摘　　要：基于黏土矿物含量、孔隙结构、储层敏感性等方面分析,针对辽宁油田X块储层压裂液对储层渗透率的伤害程度及其主要伤害因素进行了评价。分析结果表明,压裂液对储层渗透率造成的伤害程度为中等偏弱,对基质造成的伤害主要源自破胶后的残留聚合物,对裂缝造成的伤害主要源自破胶后的聚合物和残渣。Based on the analysis of clay mineral content,pore structure,reservoir sensitivity,etc.,the damage degree and main damage factors of reservoir permeability caused by fracturing fluid in block X of Liaoning Oilfield are evaluated.The analysis results show that the damage caused by fracturing fluid to the reservoir permeability is moderately weak,the damage to the matrix is mainly caused by the residual polymer after breaking the gel,and the damage to the fracture is mainly caused by the polymerization after breaking the gel objects and residues.
