摘要
通过对南翼山油田I～V油组2口井5个样品的实验分析,研究南翼山浅层油藏敏感性特征。结果表明,南翼山浅层油藏具有极强酸敏性、较强水敏性、中等—强碱敏性、中等盐敏性和速敏感性特征,储层主要伤害类型为酸敏、碱敏和水敏,其次为速敏和盐敏。建议在对南翼山浅层油藏储层进行保护时,着重考虑酸敏、碱敏和水敏性对储层的影响。
Through the analysis of five samples of 2 wells at south mountain oilfield I^V oil group,this paper researches the shallow reservoir sensitivity characteristics of the south mountain.The results show that the shallow reservoir in the south mountain has very strong acid sensitivity,strong water sensitivity,medium-alkali sensitivity,medium salt sensitivity and speed sensitivity,so the main reservoir damage can be attributed to acid sensitivity,alkali sensitivity and water sensitivity,followed by velocity sensitivity and salt sensitivity.During the protection of shallow reservoir in the south mountain,we shouldn′t ignore acid sensitivity,alkali sensitivity and water sensitivity′s influence.
