摘　　要：储层敏感性分析,能为储层注入水或采液速度制定合理的方案,减少储层的损害,为油田进一步提高勘探效果提供依据。通过储层水敏、酸敏、碱敏、盐敏、速敏综合研究,结果表明研究区长82储层存在无速敏、中等~中等偏强酸敏、中等偏强~中等偏弱水敏、弱盐敏和碱敏。Reservoir sensitivity analysis can formulate reasonable plans for the injection of water into the reservoir or the speed of production,reduce the damage to the reservoir,and provide basis for the oil field to further improve the exploration results.Through comprehensive research on the reservoirs of water-sensitive,acid-sensitive,alkali-sensitive,salt-sensitive,and rapid-sensitivity,the results show that there is no speed-sensitive,medium-to-medium-strong,acid-sensitive,medium-strong,and mediumweak,water-sensitive in the study area 82 reservoirs.Weak salt sensitivity and alkali sensitivity.
