摘　　要：为解决水平井、大斜度井等特殊情况下的井眼清洁问题,采用了雷特超级清洁纤维作为处理剂。雷特超级清洁纤维是一种由100%白色原生材料单纤维丝聚丙烯,经过特别处理的人造纤维,呈单纤维丝纤维形态,密度为1.0 g/cm3并具有安全环保、惰性、高分散性、超强悬浮性等特性,利用其在钻井液中分散后形成高的机械悬浮、携带能力来满足清洁需要。通过在玉门油田的应用表明,雷特超级纤维清扫液配制简单,具有超强携带能力,对特殊情况下的井眼清洁具有显著功效,能有效减少井下复杂和事故;不污染钻井液,返出后井浆中的清洁纤维全部由振动筛除去;雷特超级纤维用量少,综合成本低,完全能满足特殊情况下的清洁要求。A bore hole sweep formulated with a super fiber-LeiTe-was developed for use in hole cleaning in horizontal and deviated wells.LeiTe is a specially treated,white raw polypropylene in cellfibre(or single fiber) form,with a density of 1.0 g/cm3,and has characteristics of being environmentally friendly,safe,inert,highly dispersible,and excellent suspending capacity.Drilling fluids treated with LeiTe have super carrying capacity suitable for hole cleaning in horizontal and deviated wells.LeiTe sweeps are easily formulated and have almost no effect on the properties of drilling fluids.Returned to the surface from a well,the LeiTe fibers are removed by shale shakers.LeiTe is a lost cost hole cleaning agent for use in special well conditions.
