///Based on the structural analysis principle that different boundary conditions in the same stress field build different nature faults, it is commonly considered that fault subsidence of the Hailar Basin is controlled by the SSE-NNW-trending extensional stress field, forming NNE- and NEE-trending faults, with NNE-trending faults displaying distinct strike-slip deformation. Based on the coupling relation between fault activity period and accumulation period, and analysis results of typical oil and gas reservoirs, it is concluded that the early extension faults and early extension plus interim tensile shearing faults constituted sheltering faults at a critical moment of accumulation, with the sealing hydrocarbon column height generally less than the traps amplitude, and early extension and interim tensile shearing and late reversal faults were adjusted to faults.
