摘　　要：本研究采用具有吸水性能较强、比表面积大、水化反应快的材料开发了多功能材料C-P10,并以C-P10为核心材料辅以外掺料和功能性外加剂开发出经济型低密度水泥浆体系。开发的1.40~1.55g/cm^(3)水泥浆体系经济性好,配方简单,性能满足一般低压漏失地层技术套管固井。In this study,the multi-functional material C-P10 is developed by using the material with strong water absorption,large specific surface area and fast hydration reaction,and the low cost and low density cement slurry system was developed by using C-P10 as the core material supplemented by admixtures and functional admixtures.The 1.40~1.55 g/cm^(3) cement system are constructed with low cost,simple formulation,and performance suitable for casing cementing with conventional low-pressure lost formation technology.
