发布时间：2018-07-23 20:07
【摘要】：钻井岩屑是油气田开采过程中产生的固体废弃物,其可能含有重金属、有机物等污染物,若处理不当,将会对土壤和地下水环境产生危害。通过“以废治废”的研究思路,在水泥作为固化剂的前提下,添加高炉渣,采用混料均匀设计的实验方法,研究水泥添加量、高炉渣添加量、岩屑添加量、水添加量等实验因素对固化体强度和浸出毒性的影响。结果表明,通过合适的物料配比,固化体强度可达到10 MPa以上,固化体浸出毒性满足地表水环境质量标准V级要求,从而实现对钻井岩屑的无害化、资源化的利用。
[Abstract]:Drilling cuttings are solid wastes produced in the process of oil and gas field exploitation, which may contain pollutants such as heavy metals and organic compounds. If they are not treated properly, they will cause harm to the environment of soil and groundwater. Through the research idea of "treating waste with waste", under the premise of cement as curing agent, adding blast furnace slag and adopting the experimental method of uniform design of mixing material, the amount of cement, blast furnace slag and cuttings are studied. Effects of water addition and other experimental factors on solidification strength and leaching toxicity. The results show that the strength of the solidified body can reach more than 10 MPa, and the leaching toxicity of the solidified body can meet the requirements of the environmental quality standard V of surface water, thus realizing the utilization of drilling cuttings without harm and resources.
