摘　　要：在胜利油田深部泥岩地层钻进时,由于井内温度高、高密度钻井液固相含量高,特别是低密度固相含量高,同时因地层等原因产生的以CO32-、HCO3-为主的无机离子的影响,导致钻井液流变性能难以控制。有机胺处理剂由于具有极强的抑制黏土水化分散的能力,对黏土等低密度固相起到了"钝化"作用,能够明显改善钻井液的流变性,提高钻井液的稳定性。通过在利深102和桩古18-3井的应用,表明有机胺处理剂是解决胜利油田深部泥岩地层施工中钻井液流变性能控制的有效办法。Drilling fluid rheology control has long been difficult in deep shale drilling in Shengli Oilfield because of the existence of high formation temperature,high mud density,high solids(especially low density solids)content,and CO2-3and HCO-3.Amines additive,because of their strong inhibition to clay hydration and dispersion,can be used to improve drilling fluid rheology in shale formation drilling,making the mud much more stable downhole.Drilling fluids formulated with amines have been successfully used in two wells Lishen-102 and Zhuanggu-18-3,with drilling fluid rheology very easy to adjust in drilling deep shale and mud stones at elevated temperatures.
