摘　　要：以研究区储层敏感性实验为依据,结合粘土矿物含量及注入水水质的分析,对长春岭地区泉四段进行储层敏感性评价,认为该区储层表现为无—弱速敏、中等偏强—强水敏、中等偏强盐敏、中等偏强酸敏和中等碱敏,储层中水敏性矿物的大量存在导致水敏和盐敏对该区储层伤害最大。因此,为避免水敏和盐敏对低温低压储层的继续伤害,在油藏开发过程中,宜采用矿化度为7 500~10 000 mg/L、水型为NaHCO3型的注入水进行水驱开发。On the basis of the experiment of reservoir sensitivity in study area and combining with the analysis of clay mineral contents and the water quality injected,the article evaluated the reservoir sensitivity of Quan 4 formation in Changchunling district.The experiment showed that the behavior of reservoirs in that area was non-velocity sensitivity of flow.It belonged to strong water sensitivity,moderate to strong salt and acid sensitivities,medium alkaline sensitivity.There exist lots of water sensitivity minerals,resulting in water and salt sensitivities,which formed the most damage to reservoirs.Therefore,in order to avoid the continuous damage to the reservoirs with low temperature and low pressure,it is considered that the water flooding development method is suitable for the reservoir development with the water salinity of 7 500-10 000 mg/L and the water style of NaHCO3.
