Composite curing agent and application
The invention provides a composite curing agent. The composite curing agent comprises a component A and a component B, wherein the component A comprises, in parts by weight, 5-10 parts of fly ash, 10-15 parts by weight of calcium oxide and/or magnesium oxide and 1-3 parts by weight of a fiber material, and the component B comprises 1-3 parts by weight of a saturated calcium chloride solution and/or a saturated magnesium chloride solution. Compared with the prior art, the calcium oxide and the saturated calcium chloride solution or the magnesium oxide and the saturated magnesium chloride act together to realize hardening; meanwhile, the fly ash is added for adsorption and the fiber material realizes strengthening, so pollutants are efficiently adsorbed, wrapped, dewatered and hardened, thereby forming dense consolidates and realizing high-efficiency curing; the obtained composite curing agent is short in curing time, small in addition amount, high in strength, low in cost and wide in application range, so innocent treatment and recycling of a wastewater-based drilling fluid are promoted, harm of drilling waste to the environment is reduced, harmlessness and recycling of the waste drilling fluid are further promoted, and safe and environment-friendly development of an oil field is promoted.
本发明提供了一种复合固化剂，包括A组分与B组分；所述A组分包括：粉煤灰5～10重量份；氧化钙和/或氧化镁10～15重量份；纤维材料1～3重量份；所述B组分包括：饱和氯化钙溶液和/或饱和氯化镁溶液1～3重量份。与现有技术相比，本发明通过氧化钙与饱和氯化钙溶液或者氧化镁与饱和氯化镁共同作用硬化，同时添加粉煤灰进行吸附与纤维材料强化协同作用，高效吸附、包裹污染物、脱水硬化，形成致密的固结物，达到高效固化效果，得到的复合固化剂固化时间短、加量少、强度高、成本低、应用范围广，以促进废弃水基钻井液的无害化处理和重复利用、减少钻井废弃物对环境的危害，进一步促进废弃钻井液无害化、资源化和推动油田安全环保开发。
