摘　　要：长武地区三叠系延长组油层具有低孔隙度、低渗透率和多种敏感性的特点,导致开采难度大。分析了延长组油层的敏感性特征和对储层的损害因素,提出了酸化处理的优选配方和防护措施,为提高长武地区低渗透油层的整体工业生产能力提供科学依据。Low porosity, low permeability and multiple sensitivities are characteristic of Yanchang Pormation oil reservoirs of Triassic Systems in Changwu Region, resulting in a large number of difficulties for exploitation. This paper analyzes some sensitive features in Yanchang Formation oil reservoirs and some factors damaging reservoirs, and suggests optimum prescriptions and protective measures of acid treatment, thus providing scientific evidences for enhancing the whole industrial production capacity of low permeability oil reservoirs in Changwu Region.
