The invention discloses a LNG / L-CNG skid-mounted gas station. The LNG / L-CNG skid-mounted gas station comprises a first sled base, a second sled base, a LNG pump sled, a low-temperature storage tank, aL-CNG pump sled and a gas filling machine; the L-CNG pump sled is arranged on the first sled base; the low-temperature storage tank, the L-CNG pump sled and the gas filling machine are integrated onthe second sled base in sequence; an unloading table is additionally arranged at the end, near the gas filling machine, of the second sled base; the end, near the low-temperature storage tank, of thesecond sled base is movably connected with the first sled base; the low-temperature storage tank discharges liquid by the head and tail ends; fences are arranged on two sides of the first sled base and the second sled base; the first sled base is connected with the end, near the low-temperature storage tank, of the second sled base; top cover plates are arranged at the tops of the fences; and thehorizontal plane of the top cover plates is higher than the horizontal plane of the top of the low-temperature storage tank. The LNG / L-CNG skid-mounted gas station has the following beneficial effects: through high integration degree, the country and industry standards are met, and the functions of an integrated gas station are expanded; and through the mode of discharging the liquid by the head and tail ends of the low-temperature storage tank, the generation of BOG is greatly reduced, and the liquid outlet speed is accelerated.
