摘　　要：江苏油田黄8断块位于苏北盆地高邮凹陷西南,钻探目的层为垛一段,完钻井深为1800-2000m,黄8断块位由于长时间的注采,地层压力紊乱,钻井液使用密度较高,给水平井的钻井施工安全带来固相控制难、摩阻扭矩控制难度大、携砂困难,易形成岩屑床等技术难点。采用悬浮乳液钻井液,应用表明,钻井液性能稳定,抑制性强,润滑防卡性能好,悬浮携岩能力好,易于维护,满足了施工需要。Jiangsu Oilfield is located in Block 8 Huang Gaoyou Sag southwest,drilling object layer stack section,finished drilling depth of 1800-2000m,yellow 8-bit block due to prolonged injection and production,formation pressure disorders,the use of drilling fluids higher density,for drilling horizontal wells to bring safe solids control difficult,difficult to control the friction torque,carrying sand difficulty,easy to form cuttings beds and other technical difficulties.By suspension emulsion drilling fluid application shows stable drilling performance,strong inhibition,good lubrication of the anti-seizure properties,good suspension rock carrying capacity,easy to maintain,to meet the construction needs.
