废弃聚磺钻井液固相资源化绿色处理剂

Green treatment agent for waste polysulfonate drilling fluid solid phase resourceful utilization

  • 摘要: 随着国家环保要求的日趋严格,聚磺钻屑的有效处置成为了油气田企业亟需解决的问题,传统处置方式固化填埋、制备建材等存在潜在环境风险大、消纳能力受限等不足,而且聚磺钻屑中丰富的有机质没有得到有效利用。为此提出通过添加绿化土改良剂,将聚磺钻屑制备成绿化土,以实现对聚磺钻屑的资源化无害化处理。基于响应曲面法,得到了改良剂的最佳配方为生物质活性炭A、腐殖酸钠B、复合生物肥C、鱼骨粉D、柠檬酸E和仿生固化剂F的质量比为4.00∶1.80∶0.15∶0.15∶1.00∶3.00。应用该改良剂将威204H10平台聚磺钻屑制备成JH-绿化土,土壤发芽指数由15.77%提高到91.10%,COD、pH、有机质含量、总石油烃等指标均符合国家相关标准,浸出液中重金属含量符合GB/T 14848—2017《地下水质量标准》要求。该技术为聚磺钻屑的无害化资源化处置开拓了新思路,提高了聚磺钻屑的资源化率。

     

    Abstract: With increasingly stringent national environmental protection requirements, the effective disposal of polysulfonate drilling waste has become an urgent issue for oil and gas enterprises. The traditional disposal methods such as curing landfill and preparing building materials have some shortcomings such as potential environmental risks and limited absorptive capacity, while the abundant organic matter in polysulfonate drilling waste remains underutilized. Utilizing greening soil prepared from polysulfonate drilling waste (V204H10) enables resourceful and harmless treatment of V204H10. By employing the response surface method, we obtained the optimal formulation of the improver with a mass ratio of 4.00∶1.80∶0.15∶0.15∶1.00∶3.00 for biomass activated carbon, sodium humate, compound biological fertilizer, fish bone meal, citric acid, and bionic curing agent, respectively. The soil germination index of JH-greening soil prepared using this amendment was significantly higher than that of V204H10. Moreover, COD, pH, organic matter content, and total petroleum hydrocarbon concentrations in JH-greening soil all complied with relevant national standards, while the heavy metal content in the leaching solution met GB/T 14848—2017 Groundwater Quality criteria. This technology introduces a novel approach to the harmless disposal of polysulfonate drilling waste and enhances their comprehensive resource utilization rate.
