Abstract: The present crude oil storage can be divided into three types: surface storage, underground salt cavern storage and groundwater-sealed cavern. However, it is difficult to popularize these three types of storage in China due to the actual situation. Through analysis of abandoned mines in Northeast China, combined with the engineering technical conditions of underground crude oil storage, the paper puts forward the conception of using abandoned mines to transform underground space for the construction of strategic crude oil storage. It is suggested that concerning department should carry out comprehensive investigation of underground space of abandoned mines in Northeast China, and start relevant test and research work such as sealing experiment of underground oil and gas storage as soon as possible.
