摘　　要：针对准噶尔盆地西部隆起乌夏断裂带哈山南缘斜坡带哈浅6井预探井,该井上部地层易发生井漏;八道湾组煤层已发生井塌;三开石炭系孔隙及裂缝发育,已发生井漏及井塌的实际状况,通过使用聚合物非渗透钻井液体系和强抑制成膜钻井液体系,配合现场钻井液维护处理工艺,实现顺利钻至目的层。Haqian 6th well is located in the southern slope of Wuxia fault belt in Junggar basin. An investigation of the well shows that the upper stratum tends to have leakage and Badaowan coal seam has had collapse. It is sugges- ted that polymer non - invasive drilling fluid and compulsive membrane drilling fluid can be suited to drilling fluid maintenance and treatment techniques, eventually completing the drilling task.
