地质矿产部探矿工艺研究所与地质、石油部门有关野外队协作进行的惰性堵漏材料及其堵漏试验装置这一科研课题已取得良好成果，受到野外队的普遍欢迎。惰性材料堵漏即是将一些惰性材料诸如核桃壳、棉籽壳、贝壳、云母、蛭石之类，混入冲洗液内灌到钻孔中，使之随同冲洗液进入裂隙通道，产生架桥、充填、阻塞，以达到堵漏的目的。用这种方法堵漏， The research project of the Institute of Prospecting Technology for Geology and Mineral Resources, in collaboration with the relevant field teams in the geology and oil sectors, has carried out good results in the field of inert plugging materials and plugging test devices and is generally welcomed by field teams. Inert material plugging is the inert material such as walnut shells, cottonseed shells, shells, mica, vermiculite and the like, mixed into the irrigation fluid irrigation into the borehole, with the flushing fluid into the fissure channel, resulting in bridging, filling , Blocking, in order to achieve the purpose of plugging. Plugging in this way,
