摘　　要：酸化压裂是油田增产增注的一项重要工艺。延长石油有限责任公司瓦窑堡钻采公司地处鄂尔多斯盆地,是典型的低孔特低渗油层,其主力开发层长6油层孔隙度低,渗透性差,非均质性强,敏感性矿物含量较高,通过模拟地层水对岩心的驱替实验及储层的敏性评价,优选出合适的酸液配方。acid fracturing oil production by injection is an important process. Yan Chang of the limited liability company Wayaobao oil drilling company is located in the Ordos Basin, is a typical low- permeability reservoir Conte, the development of its main reservoir of chang- 6 low porosity, permeability poor, strong heterogeneity of the sensitivity of mineral content Higher , by simulating the formation water core and the displacement of the reservoir--evaluation, optimization suitable acid formula.

关 键 词：特低渗透 酸敏 岩心流动试验
