摘　　要：分析了矿渣MTC浆失水、稠化时间、抗压强度、流变性、静胶凝强度发展等性能特点及技术优势,并与常规水泥浆进行了对比分析,认为矿渣MTC体系大部分性能指标优于水泥浆体系,可以满足现场固井技术要求。应用矿渣MTC固井技术解决了低压易漏失井、高压气井、调整井、长裸眼长封固段及复杂压力体系固井等固井技术难题,固井质量明显优于常规水泥浆固井。This paper presents the technical advantages and properties of MTC, including fluid loss, thickening time, compressible strength, rheology, gel strength developments,etc. In addition, on the basis of comparison analysis with normal cement slurry, it is concluded that major properties of the MTC system are better than normal cement slurry, and it can meet the demand for field cementing. Cementing with the MTC can resolve cementing challenges in low formation pressure wells, high pressure gas wells, adjustment wells, long open hole wells and wells with complex formation pressures, cementing qualities are remarkable better than normal operations.
