Reservoir fracture identification method and device, electronic equipment and storage medium

The invention provides a reservoir fracture identification method and device, electronic equipment and a storage medium. The method comprises the following steps: acquiring gas logging data of a target reservoir; wherein the gas logging data at least comprises a gas logging total hydrocarbon value at each depth position in the target reservoir; determining an abnormal depth position in the target reservoir according to the gas logging total hydrocarbon value at each depth position in the target reservoir, and determining an abnormal degree of the gas logging total hydrocarbon value corresponding to each abnormal depth position in the target reservoir; and according to the abnormal degree of the gas logging total hydrocarbon value corresponding to each abnormal depth position in the target reservoir, determining the development degree of the crack in each abnormal depth position in the target reservoir. According to the method, the crack can be quickly identified at a well position with less logging and seismi
