摘要: 废弃油基钻井岩屑是钻井过程中产生的固体废物,是含有矿物油、酚类化合物及重金属的复杂多相体系,已被列入国家危险废物名录。为了给废弃油基钻井岩屑资源化利用提供依据,实验研究了废弃油基钻井岩屑的含油率、含水率、高位热值、元素含量及焚烧特性。结果表明:废弃油基钻井岩屑的含渣率为74.006%,含油率为18.71%,高位热值为8 000~9 000 J/g,可以在不需要辅助燃料的条件下稳定燃烧;废弃油基钻井岩屑的总硫含量为5.30%,可燃物组分全硫含量的平均值为1.25%,氮含量也较低,因此燃烧产生的氮氧化物及硫氧化物气体的排放量不大;氯含量为0.3467%,产生二噁英机率较小;焚烧后的灰渣中重金属含量较低,可以回填利用。Abstract: Drilled cuttings from wells drilled with oil base drilling fluids are waste solids containing mineral oils, phenol chemicals and heavy metals. As a complex multiphase system, the waste solids have been listed in the national hazardous waste catalog. To reuse the oil base waste solids, laboratory experiments have been conducted on the oil base waste solids for their percent residue oil retained, water content, gross heat value, element content and burning performance. The experimental results showed that an oil base waste solid with residue of 74.006%, retained oil of 18.71%, and gross heat value of 8,000-9,000 J/g can burn steadily, without the need for auxiliary fuels. The waste solids tested had gross sulfur of 5.3%, and the average total sulfur content in the combustible constituent was 1.25%, and the nitrogen content was low. All these factors considered, it can be concluded that the discharge of the oxides of nitrogen and the oxides of sulfur from the combustion of the waste solids would not be high. The chlorine content of the waste solids was 0.346,7%, meaning that the probability of producing dioxin would be low. Heavy metal content in the burned residue of the waste solids was low, indicating that the waste solids can be backfilled.
