摘　　要：通过对长庆油田水基钻井废物泥浆池原位处理的历史情况进行调研,分析了泥浆池对周围植被和土壤的影响。结果表明:泥浆池内玉米、牧草的平均生物量分别比泥浆池外高出15.3%和44.5%,钻井废物提高了土壤的碱性。玉米籽粒及泥浆池内、外土壤中的重金属含量均未超标,泥浆池对牧草中的重金属含量无明显影响。分析发现钻井废物中含有大量的微量元素,可以促进植被生长,且钻井液添加物可以提高土壤肥力,使其具有土壤化利用的潜力,为钻井废物资源化利用提供了方向。By investigating the historical situation of the mud pools in-situ treatment to the waterbased drilling waste in Changqing Oilfield,the impacts of mud pools on surrounding vegetation and soil were analyzed.The results showed that the biomass of corn and forage in the mud pool were 15.3%and 44.5%higher than those outside the mud pool,respectively,and the mud increased the soil alkalinity.The content of heavy metals in corn kernels,soil inside and outside the mud pool did not exceed the standard,also,the mud pools had no significant effect on heavy metal content in forage grass.Analysis found that drilling waste contain lots of trace elements which can promote vegetation growth,and drilling fluid additives can improve soil fertility,making it have the potential for soil utilization.As a result,a new direction for the resource utilization of drilling waste was provided.
