Oil field oil water, mud closed evacuation recovery system

The utility model discloses a oil-water, closed sediment emptying recovery system, which comprises an oil tank, an oil transfer pump, an emptying pipeline and a main line. The inlet of the oil transfer pump is connected to the fluid discharge mouth of the oil tank. The outlet of the oil transfer pump is connected to the main line, and the emptying pipeline is connected to the oil tank. A heater is comprised, in which the heat sink is arranged inside the oil tank. The inside of the oil tank is provided with an emptying nozzle in which the emptying pipeline is connected. In the utility model, through the diffluence washing of the emptying nozzle for the oil-water and sediment, through the heating of the heater, the liquidity of the oil-water and sediment is increased. Thus the speed of oil-water emptying is fast with timely sediment ejection, and the oil-water and sediment can also be sent to the main line for recovery. The utility model is applicable for the emptying of the single well pipelines, which is also
