苏联在聚丙烯酰胺和 M—14聚合物的基础上研制成聚合物冲洗液和聚合物—膨润土冲洗液,可适用于通常条件下,特别是在复杂地质条件下进行金刚石钻进和硬质合金钻进。这种新的冲洗液在绳索取心钻进时最为
Based on polyacrylamide and M-14 polymer, the Soviet Union developed a polymer rinse solution and a polymer-bentonite rinse solution. It can be applied to diamond drilling and cemented carbide under normal conditions, especially under complex geological conditions Drilling. This new flushing fluid is most likely to be coring in the rope
