The invention discloses a three-dimensional carving method and device for strike-slip fracture and a reservoir of a sedimentary basin. The method comprises the steps that the plane distribution range and the depth range of a fracture zone are determined according to sensitive attributes of the fracture zone; according to the above range, the data body of the fracture internal structure sensitive attribute and the data body of the reservoir structure response sensitive attribute are cut along the fracture zone; constructing a three-dimensional space structural form of strike-slip fracture according to the fracture data body, and constructing a three-dimensional space structural form of the reservoir according to the reservoir data body; and according to the added well data and the target layer data, establishing a well-strike-slip fracture-reservoir space relation. According to the method, the defect that the strike-slip fault zone is difficult to present spatially is overcome, spatial distribution of the frac
