摘　　要：以水基钻屑为主要原料制备烧结砖,综合研究并分析了不同掺量水基钻屑烧结砖力学性能、热重性能。结果表明,水料比为0.18、水基钻屑替代40%黏土、外掺5%的粉煤灰、10%的煤矸石,焙烧温度1000℃,焙烧时间100 min的条件下,制备出密度为1310 kg/m3,抗压强度为16.9 MPa的烧结砖;通过XRD、FT-IR和SEM分析结果表明,水基钻屑中的硅铝质矿物参与了体系反应;页岩气水基钻屑作为烧结砖的部分原料,是一种资源化、无害化的安全环保处理方法。The water-based drilling cuttings（WDC） were used as the main raw material to prepare the sintered brick. This paper comprehensive analysis the effects of WDC amount on mechanical and thermogravimetric properties. The results showed that properties of WDC sintered brick which was prepared according to an ingredient design, water to material ratio of 0.18, WDC replacing of 40% clay, mixed 5% fly-ash and 10% coal gangue, calcination temperature 1000 ℃ and calcination time 100 min. The capacity of the brick was 1310 kg/m3, compressive strength was 16.9 MPa.The results of XRD, FT-IR and SEM showed that the salic mineral of WDC were involved in thereaction. Using the WDC to make sintered brick is a security and environmental way which in recycling and harmless.
