摘　　要：MTC具有与泥浆相容利于提高顶替效率的技术优势和可利用泥浆降失水材料控制体系的稳定性而节约降失水材料成本的经济优势。超低密度MTC可用于低压易漏地层固井。我院通过大量的理论及实验研究,研制出适于新疆油田多种泥浆体系、密度可低至1.2g/cm3、50℃常压养护24hr抗压强度可达8MPa以上、综合工程性能良好的新型超低密度MTC。MTC is favourable to enhancing displacement efficiency because it's compatible with mud, and to decreasing cost by stabilizing itself with filtrate reducers in mud. Low density MTC is suitable to cement low fracture pressure formations. By theritical and experimental studying, a new type MTC with low density, being able to be made up of various muds, being compatible with various muds, with a lowest density of 1. 2g/cm3 and 24 hours compressure strength no less than 8 MPa at 50℃ and 0. 1MPa, has been developed.
