锅锥是由火箭锥改制成的,它有象锅一样的锥头,群众就叫它为“锅锥”。由于我们设计的井型结构为筒管井形式,上部20～30米的井筒内径为700毫米,下部管井深(由地面起)50～70米,内径为200～300毫米。
The cone is made from a rocket cone. It has a cone like a pan. The masses call it “pan cone.” Since we designed the well structure in the form of a tube well, the borehole diameter of the upper 20 to 30 meters is 700 mm and that of the lower tube 50 to 70 meters (from the ground) and the inner diameter is 200 to 300 mm.
