The Longwangmiao Formation Well MX20. Photos of fluid inclusion petrologic and petrographic observation of (H1–H3) (-) 4597.29-4598.73 m, synchronous capture of gas-phase inclusions, bitumen inclusions, and brine inclusions in dolomite under different polarized light multiples. (H4) (UV) Non-gas-phase and bitumen inclusions. (J1), (J3), and (J4) (-) 4618.64-4618.86 m, synchronous capture of gas phase+bitumen inclusions, bitumen inclusions and aqueous inclusions in dolomite displayed at different polarized light multiples. (J2) (UV) Nonfluorescing hydrocarbon inclusions.
