Zusammenfassung:	The utility model provides an underground oil injection device which comprises an oil tank, a reversing valve and an automatic oil injection mechanism. An oil storage area and a storage area are arranged in the oil tank and are arranged in a separated mode. The automatic oil injection mechanism is arranged in the storage area; the oil storage area communicates with the automatic oil injection mechanism through a second pipeline. And a reversing valve is arranged on the second pipeline and is used for two-way selection of filling oil into the oil tank and filling oil into the underground device. According to the underground oil injection device, the oil tank, the reversing valve and the automatic oil injection mechanism are arranged in the underground oil injection device, through mutual cooperation of the reversing valve and the automatic oil injection mechanism, the reversing valve is adjusted before the underground device descends, oil is injected into the oil tank through the automatic oil injection mechan
