The main aspects of this are: First, the water and soil in the lower layers are easily confused with the oil, resulting in a lack of assurance of the purity of the oil extracted. Secondly, there is no support inside the oil mine, so there is a great safety hazard for workers&#8217; lives and equipment operation. In this case, many designers aim to reform the whole set [&hellip;]"}
