Method for preparing sintered ceramsite by using offshore water-based drilling solid phase
The invention discloses a method for preparing sintered ceramsite by using an offshore water-based drilling solid phase, which comprises the following steps: S1, carrying out solid-liquid separation on drilling mud to obtain solid-phase drilling cuttings and a liquid phase; carrying out filter pressing dehydration on the liquid phase to obtain a filter cake; S2, treating the drilling cuttings and the filter cake into granular powder; S3, mixing the granular powder with fly ash, adding water, and uniformly stirring to obtain ceramsite pellets; and S4, drying the pellets, and firing to obtain the ceramsite. According to the method for preparing the sintered ceramsite from the offshore water-based drilling waste, the problem of disposal after the offshore water-based drilling waste is recovered and ashore is efficiently solved.
本发明公开了一种利用海上水基钻井固相制备烧结陶粒的方法，包括：步骤S1：对钻井泥浆进行固液分离，得到固相钻屑和液相；对液相进行压滤脱水得到滤饼；步骤S2：将钻屑和滤饼处理成颗粒粉末；步骤S3：将颗粒粉末与粉煤灰混合，加入水搅拌均匀得到陶粒料球；步骤S4：使料球干燥，然后烧制成陶粒。本发明通过采用海上水基钻井废物制备烧结陶粒的方法，高效率解决了海上水基钻井废物回收上岸后的处置问题。
