河北省滦县古马铁矿矿区地层复杂，钻探存在坚硬打滑、漏失严重、构造发育（局部断层）的现象，在总结以往钻探施工经验的基础上，提出了千米以深钻孔复杂地层的钻探施工技术措施和钻探施工质量保证措施。从钻孔结构、冲洗液选取、钻探设备、钻具配置等方面入手，提出了解决坚硬“打滑”、破碎漏失及坍塌掉块地层的处理方法，优化了钻孔施工环境和广谱护壁剂、防塌堵漏剂以及聚丙烯酰胺冲洗液的配置，改善了复杂地层的深孔钻进环境，提高了钻探生产效率，保证了钻孔安全终孔。

The formation is complex in Kumar iron mine in Luanxian of Hebei Province, hard and slipping, severe leakage and tectonic development ( partial fault) are often met during drilling.Based on the previous drilling experience, drilling technical measures and drilling construction quality assurance measures were put forward to deep drilling in complex strata of more than 1000m.From aspects of the hole structure, flushing fluid selection, drilling equipment and drilling tool con-figuration, the processing methods for solving the problems in hard and slipping, broken and leakage as well as collapse blocking formations were put forward, by which the drilling construction environment, the preparation of broad-spectrum re-taining agent, anti caving plugging agent and polyacrylamide flushing fluid were improved with higher drilling efficiency and safe well completion.
