摘　　要：针对浅层盐穴储气库井固井中存在的强度发展缓慢、水泥石韧性差等问题,开发了适用于浅层盐穴储气库井固井的低温胶乳盐水水泥浆体系。室内实验研究表明,该体系具有稳定性好、失水量低、水泥浆稠化时间可调、水泥石力学性能优良等特点,并且胶乳增强了水泥石的弹性形变能力,使水泥石韧性增强,有助于提高水泥石抗冲击破坏的能力。胶乳盐水水泥浆体系综合性能良好,能改善第一、二界面胶结,提高浅层盐穴储气库井固井质量。并成功应用于安宁盐穴储气库安资2井。For the problems of slow development of strength and poor cement paste toughness in shallow salt cavern gas storage wells,a kind of low temperature latex brine cement slurry system is developed in this paper.The experimental results show that this system has performances of good stability,low water loss,adjustable thickening time and excellent mechanical properties.Furthermore,the elastic deformation capability is improved by latex,and it also can improve the first and second interface cementing qualities of shallow salt cavern gas storage wells cementing.It is applied in well Anzi2 successfully.
