摘　　要：桩斜161井是胜利油田在桩西地区部署的一口大位移评价井。该井在钻井过程中存在造斜点浅、上部地层造浆严重、斜井段长、摩阻大、岩屑携带困难等诸多难题,针对该井特点,采用有机硅聚磺混油防塌钻井液体系和配套工艺技术顺利完成了该井的施工。现场应用表明,有机硅聚磺混油防塌钻井液具有良好的流变性,润滑防卡性,携岩能力强,有效防止了井壁失稳,满足了大位移延伸井的钻井要求。以桩斜161井为例,介绍了该地区大位移延伸井钻井液施工经验,为桩西地区大位移延伸井实现安全、快速施工提供参考。Zhuangxie-161 well is an extended reach appraisal well in Zhuangxi area in Shengli Oilfield. By using polymer sulfonate drilling fluid mixed with oil,with matching technology,the well was successfully drilled. Application of the scene showed that this drilling fluid had good rheology, lubricaty and pipe-sticking prevention, good carrying rocks ability, which effectively prevented the wallbore instability and protected the reservoir, met the requiements of extended reach appraisal well. Take Zhuangxie-161 well as an example,this paper introduces the technical difficuhies in the drilling construction and the principle of system selecting, advances the successful experience of treatment at the scene. Some references are advised for safe and fast construction in this area.
