The invention belongs to the technical field of the petroleum geological exploring evaluation, and discloses a method for quickly identifying low-resistance hydrocarbon reservoir by utilizing digitalcore technology. The method comprises the step of quickly identifying and evaluating the low-resistance hydrocarbon reservoir by adopting a cross plot of an area mid-value of a pore unit and montmorillonite content multiplying deep resistivity/stratum water resistivity and the cross lot of the area multiplying pore radius of the pore unit/pore form factor mid-value and montmorillonite content multiplying deep resistivity/ stratum water resistivity. The oil reservoir, the low-resistance oil reservoir, a suspicious layer, a high-resistance water layer and a general water layer can be obviously distinguished; compared with the existing conventional identification valuation method, the method has the features of being fast and accurate and obvious in distinguishing effect. 本发明属于石油地质勘探评价技术领域，本发明公开了种利用数字岩心技术快速识别评价低阻油气层方
