The invention belongs to the technical field of oil exploration and development oil and gas reservoir identification, particularly relates to a low-resistance oil and gas reservoir identification method and system, and aims to research the oil content level of stratum rock debris, accurately identify a low-resistance oil and gas reservoir and obtain reliable data parameters. The method comprises the following steps: acquiring a rock sample of a to-be-researched area by adopting a logging special technology; an element logging device is adopted to obtain elements of types required by the rock sample and corresponding contents, and elements of preset types and contents of the elements are screened out in combination with big data information; obtaining the shale content and the sand content of the reservoir; the shale content of the reservoir comprises the content of an aluminum element and the content of an iron element, and the sandy content of the reservoir comprises the content of a silicon element and the
