    摘要
  • 摘要: 针对塔北玉东区块上部地层缩径阻卡、膏盐岩层蠕变缩径和垮塌卡钻、高密度盐水钻井液流变性及滤失量控制难等一系列问题，玉东7-4-2井通过对钻井液技术的优化，解决了阻卡和膏盐层井眼稳定等问题，易塌层段井径扩大率仅为7.5%，钻井周期比邻井节约20 d以上，提速效果显著。

     

    Abstract: Drilling operations in the Block Yudong in north Tarim Basin have long been faced with a series of problems, such as tight hole in the upper formations which results in drag and overpull, creeping of salt/gypsum sections which results in tight spots, sloughing and pipe sticking, and difficulties in controlling rheology and filtration of the drilling fluid because of high mud weight. By optimizing the drilling fluid technology on the well Yudong-7-4-2, drag, overpull and borehole wall instability have all been resolved. Percent hole washout in easy-to-collapse sections was only 7.5%. Drilling time was 20 days less than wells drilled nearby, indicating the ROP was greatly increased.
