摘要：
随着油气田开采难度和并下情况复杂化程度的增加，常规水泥环易发生脆裂，进而影响水泥环的层间时隔作用，影
响并筒完整性。硫铝酸钙水泥是一种性能优良的固并水混泥材料，为了了解硫铝酸钙水泥在围并工程中应用的潜力，制作了玻璃纤维增强硫铝酸钙水泥石(CSA/GRC)样品，利用X射线衍射法分析不同龄期硫铝酸钙水泥的晶体水化产物；通过三轴应力。应变实验，测试CSA/GRC固井水泥石的力学性能；采用扫描电子显摄镜观察CSA/GRC固井水泥石断裂面的微观形貌，分新玻璃纤维在硫铝酸钙水泥石中的增初机理。研究结果表明：CSA/GRC固并水泥石具有良好的韧性和力学形变能力，轴向抗压强度和极限应变值比常规玻璃纤维图并水泥石分别提高了约45%和300%；玻璃纤维与硫铝酸钙水泥体系之间有良好的复合能力，纤维抗肩蚀性能强；通过应力分散作用和桥联作用，玻璃纤维可约束求裂缝的进一步扩展，从而提高固并水泥石的树性。

[eao aea soes ap o ado e a se e [ o aap aoap a s ae cement sheath tends to suffer brittle failure and its interlayer isolation effect is impacted. And consequently, wellbore integrity is dam-aged. Sulphoaluminate cement is a kind of cement material with excellent properties. A sample of fiber glass reinforced sulphoaluminate set cement (CSA/GRC) was prepared to clarify its application potential in cementing engineering. The crystal hydration products of sulphoaluminate cement with different ages were analyzed by means of X-ray diffraction method. The mechanical property of CSA/ GRC set cement was tested by using triaxial stress-strain experiment. The microscopic morphology on the rupture plane of CSA/GRC esseeesse set cement was investigated. It is indicated that CSA/GRC set cement has good toughness and mechanical deformation capacity and its as se a as e % e % re es en e s sso combination between fiber glass and sulphoaluminate cement system is good and fiber is highly corrosion resistant.
