根据界村芒硝矿藏的地质条件 ,对水溶开采埋深 80 m、厚 3.8m芒硝矿所要求的对接井钻进工艺进行了试验和研究 ,在试验中对接钻孔的最大弯曲强度达到 6.2 7°/ m,在芒硝矿层中水平保直钻进了 70 .55 m
According to the geological conditions of boundary mirabilite deposits, the drilling technology of the butt well required for water extraction with depth of 80 m and thickness of 3.8 m was studied. The maximum bending strength of butt holes reached 6.27 ° / m, the level of bergamite drilled 70.55 m
