    摘要:

    针对伊朗TALEGHAN水库大坝观测仪器孔在松散、架空、透水性极强的堆石层中钻进存在的取心困难、泥浆漏失严重、孔壁稳定性差等问题,引进以KL植物胶为主要原料的处理剂配置成无固相冲洗液和不分散低固相泥浆,并配合一系列堵漏材料在现场的综合应用,取得了良好的钻进效果。介绍了KL植物胶的配方、泥浆性能指标及护壁堵漏效果,为今后类似地层钻孔提供了可借鉴的经验。

    Abstract:

    In respect of the coring difficulties, such as high circulation loss, low stability, encountered in observatory borehole drilling in loose backfilled rubbles with many cavities and high osmosis at the TALEGHAN Reservoir project in IRAN, a solid-free, non-dispersible. Drilling fluid is concocted with the KL vegetable colloid as the main additive, which, combined with sealing agents, has achieved good results at site. The composition of the KL colloid, properties of the drilling fluid and the sealing effectiveness are described, providing some experience for drilling in similar conditions.
