在我们这个矿区里,二叠纪岩层比较厚,都用合金钻进。而用方形合金片钻进页岩小时效率只能达到1．2-1．5公尺左右。用菱形薄片钻进,虽然效率较高,但因砂页岩与薄层细砂岩的互层软硬不均,容易碰掉合金,而且菱形合金片供应也不足,想用全面钻进地质上又不允许。在这种情况下我们全体职工开动脑筋,想办法,经研究将方形合金磨成掉边菱形合金使用,结果提高效率二倍,小时进尺达2．4- 3．2公
In our area, the Permian strata are relatively thick and are all alloyed. However, the hourly efficiency of drilling shale with square alloy sheet can only reach about 1.2-1.5 meters. With rhombic thin sheet drilling, although the efficiency is high, but due to sand shale and thin sandstone interlaced hard and soft, easy to get out of the alloy, but also the supply of diamond alloy sheet is not enough, would like to use a comprehensive drilling geological Not allowed. In this case, all our employees brains, think of a way, the study of the square alloy into the diamond off the use of the alloy, resulting in two times the efficiency, the hour footage into the 2.4-3.2 public
