在对川东北普光地区长兴-飞仙关组礁滩型储层岩性、黏土矿物、物性特征研究的基础上，对研究区33套193个岩心进行岩石敏感性实验。结果表明：普光地区长兴-飞仙关组储层岩石速敏、水敏和碱敏的损害程度为弱-中等偏弱；盐敏对T1f1-2储层的损害程度为中等偏弱-中等偏强，对P2ch储层为零-弱；酸敏对T1f1-2储层的损害程度为中等偏弱-强，对P2ch储层为零-中等偏强。总体看来，川东北普光地区长兴-飞仙关组礁滩型储层的敏感性为弱到中等偏弱。该地区的储层敏感性研究为下一步的油气开采提供了依据。

Based on the study of lithological, clay mineral and physical characteristics of the reef reservoir in Changxing-Feixian-guan formation of Puguang area, Northeast Sichuan, the sensitivity experiments of 33 sets, 193 cores in the study area are systemati-cally studied. The result shows that the damage degree of velocity sensitivity, water sensitivity and alkali sensitivity range from weak to medium(-). That of salinity sensitivity to T1f1-2 reservoir is from medium(-) to medium(+), and to P2ch is 0 to weak. That of acid sensitivity to T1f1-2 reservoir is medium(-) to strong, and to P2ch is from 0 to medium(+). Overall, the sensitivity of the reef reservoir in Changxing-Feixianguan formation of Puguang area, Northeast Sichuan is weak to medium(-). The sensitivity study of this area provides the basis for the further oil and gas exploitation.
