研究适合于金刚石绳索取心钻进护孔防渗漏的冲洗液,是当前的一项迫切任务。这种冲洗液不仅应具备普通护孔浆液的特点,而且还必须具备携带岩粉、排除岩粉、润滑、防锈,以及防钻杆内壁结垢等性能。国内外的研究情况国内外早就开展了对泡沫泥浆的研究。五十年代末,我们曾在钢粒和金刚石双管钻进中进行了泡沫泥浆的实验,并取得了良好的效果。将这种泥浆应用于金刚石绳索取心钻进,钻杆内 It is an urgent task to study the rinsing liquid suitable for diamond rope core drilling seepage prevention and leakage prevention. This flushing fluid should not only have the characteristics of ordinary shield slurry, but also must carry rock dust, rupture of rock powder, lubrication, rust prevention, and anti-scaling rod inner wall performance. Domestic and foreign research situation Has carried out the research of foam mud at home and abroad for a long time. In the late fifties, we experimented with foam mud in steel and diamond twin-pipe drilling and achieved good results. This mud should be used in diamond ropes coring drilling, drill pipe
