| 摘 要： | 镇平277-2井是浅层漏失水平井,因底层压力低、孔隙发育,在钻井过程中发生多次漏失,使固井水泥返高难以保证；水平井段不测井径,水泥量难以把握；套管在重力和弯曲应力作用下,贴靠井壁,套管居中度差；岩屑在重力作用下沿井眼径向沉降在井眼下侧,且采用油基钻井液钻井,致使顶替效率低,严重影响水泥与地层及管柱的胶结强度.由此提出了一系列固井技术措施,进行了冲洗隔离液设计,采用防漏、低失水量、零析水、高沉降稳定性、微膨胀水泥浆体系,避免了水泥石体积的收缩,应用复合流态顶替、下套管摩阻预测、合理选择及安放扶正器等技术,获得了较好的固井质量.

| Abstract: | Because of low formation pressure and high porosity,partial and total losses happened when drilling at horizontal section of well Zhenping277-2.While cementing,some difficulties,such as the low cement top,bad centralization of casing strings,cutting deposition and low displacement efficiency were encountered.Cementing technical measures were proposed,like using washing spacer fluid,applying a cement slurry with the characteristics of lost circulation prevention,low filtration,no water flush-out and micro-sw... |
