摘　　要：通过室内试验从油基钻井液对储层润湿性的影响和不同层位岩心经油基钻井液污染后渗透率的恢复值两方面展开,重点分析了储层润湿性的改变和储层损害的影响因素和原因,说明了储层润湿性的改变是储层损害的一个重要因素,并给出了一些新的储层保护改进措施和建议。This article starts by laboratory experiments from oil -based drilling fluid on reservoir wettability and the permeability recovery of different layers of core contaminated by oil - based drilling fluids , focusing on analysis of the influencing factors and the causes of the change of reservoir wettahility and reservoir damage, the conclusion is that the change of reservoir wettability is an important factor on reservoir damage, and finally, gives a new reservoir protection improvements and recommendations.
