In the Eogene and Neogene, Qaidam Basin experienced the multiphase tectonic movement; the paleoclimate evolved from warm-humid to arid; the water in the basin was gradually salinized; the depocenter migrated from west to east. The master factors and developmental characters of lithologic hydrocarbon reservoirs have their own particularity. Taking the fine exploration zones of the southwest hydrocarbon-rich depression in Qaidam as the key point, with the analysis of source-rock distribution, sedimentary evolution and sedimentary system distribution, the author proposes that the density difference increases after the fluvial water enters, then clam and bar sand bodies are formed easily due to density flow. Highstand system tract and transgressive system tract below the maximum flooding surface are the main exploration areas of lithologic reservoir.
