摘　　要：分析了鄂北气井长裸眼段固井的难点,针对由于封固段长而引起的施工时间长、施工压力和液柱压差大等问题,采取了双级固井工艺、选用双凝水泥浆及低密度水泥浆体系等技术措施。现场应用表明,这些技术措施较好地解决了该地区封固长裸眼段的难题。This paper analyzes the challenges to cementing long open hole in north of Hubei province. In order to cope with the long operation time and the high operation pressure and great differential hydrostatic pressure, the two stage cementing technique, the separably setting cement slurry and low density slurry are employed. Field applications show that these techniques can be successfully used to solve problems of cementing the long open holes in this area.
