利用国产露头砂岩岩心,研究了亲水条件下,无机盐对岩心采用表面活性剂溶液进行自发渗吸驱油的规律和采收率的影响。
5) exposed rock formation
裸露岩层
6) coal seam outcrop
煤层露头
1.
To use 3D seismic prospecting in control of coal seam occurrence form has demonstrated its satisfying effects,but for a mine's high yield,high efficiency geological guaranteeing system still need to determine geological anomalous bodies of“barren zone”,subsided column,gob area and coal seam outcrop etc.
三维地震勘探在控制煤层赋存形态方面已取得了令人满意的效果,但矿井高产高效地质保障系统需要准确圈定“无煤带”、陷落柱、老窑采空区、煤层露头等地质异常体。
补充资料：露头
地下岩体、地层和矿床等露出地表的部分。可分为天然露头和人工露头。野外地质观察中直接或间接地反映了岩石性质、地层产状、地壳变动及矿产蕴藏等情况。
