The overall objective of this research project was to investigate the heavy metals environmental security control of resource utilization of shale gas' drilling cuttings. To achieve this objective, we got through theoretical calculation and testing, ultimately and preliminarily determine the content of heavy metals pollutants, and compared with related standards at domestically and abroad. The results indicated that using the second Fike's law, the theoretical model of the release amount of heavy metal can be made, and the groundwater environmental risk as main point compared with soil. This study can play a role of standard guidance on environmental security control of drilling cuttings resource utilization by the exploration and development of shale gas in our country.
本研究项目的总体目标是研究页岩气钻井岩屑资源利用过程中的重金属环境安全控制。为了实现这一目标，我们通过理论计算和测试，最终初步确定了重金属污染物的含量，并与国内外相关标准进行了比较。结果表明，采用第二菲克定律，可以建立重金属释放量的理论模型，并以地下水环境风险为重点，与土壤进行比较。本研究可以为我国页岩气勘探开发过程中钻井岩屑资源利用的环境安全控制提供标准指导。
