Geopolymer curing agent for water-based drilling cuttings and treatment method of geopolymer curing agent
The invention provides a geopolymer curing agent for water-based drilling cuttings and a treatment method of the geopolymer curing agent, and the curing agent comprises the following components in parts by mass: 40-50 parts of crushed drilling cuttings, 30-40 parts of slag, 5-10 parts of silica fume, 5-10 parts of water glass and 5-10 parts of a chemical treatment agent DH-2. According to the advantages of a geopolymer material, namely high early strength, good durability and thermal stability, a curing raw material with geopolymer material slag and silica fume as main materials is developed, and a chemical treatment agent DH-2 is added to better seal heavy metal ions and the like in the drilling cuttings; a treatment method is provided, formed slurry is injected into a waste well through a single-screw pump, and reutilization of waste in well cementation is achieved. The safety is enhanced, and the pollution of rock debris is reduced.
本发明提供一种水基钻屑用地聚物固化剂及其处理方法，所述固化剂以质量分数记，包括以下组分：40‑50份粉碎后的钻屑、30‑40份矿渣、5‑10份硅灰、5‑10份水玻璃、5‑10份化学处理剂DH‑2。本发明根据地聚物材料的优势，即早期强度高、良好的耐久性和热稳定性，研发出一种以地聚合物材料矿渣、硅灰为主的固化原材料，并添加一种化学处理剂DH‑2，对钻屑中的重金属离子等进行更好的封固；并提出一种处理方法通过单螺杆泵把形成的浆体注入废弃井中，实现了废物在固井上的再利用。加强了安全性，减少了岩屑的污染。
