页岩气油基钻屑脱油灰渣资源化利用进展

针对页岩气开发过程中产生的油基钻屑在堆放、运输和处理过程中均有可能对环境造成危害的问题,研究油基钻屑脱油灰渣的处置和资源化利用现状。在实际应用中,各种资源化利用技术由于政策、环保标准、经济性等原因,除水泥窑协同处置技术外,很多技术还不能大量推广应用。文章通过系统调研,阐述了各项技术的原理、优缺点及资源化利用所面临的政策障碍、实际应用及二次污染等问题,指出了资源化利用技术在开发过程中需要加强过程污染控制、开展相关政策和标准制定、提高产品高附加值等方面研究。

Current Research Processes in Utilization of Oil-based Drilling Cuttings Residue

Oil-based drilling cuttings(OBDC)are a typical hazardous waste in drilling process of exploration for shale gas resources.The production,storage,transportation and processing of OBDC may have negative impact on the local ecological environment and residents’health.The disposal and utilization of OBDC&residues have become hot topics.Currently,the promotion of OBDC utilization technologies have been limited by policies,environmental standards and economics,except co-processing in cement kiln.This study demonstrated a systematic investigation on the mechanism,advantage/disadvantage,policy obstacle in resource utilization,application and secondary pollution of OBDC treatment technologies.Furthermore,this study provided three prospects for the follow-up studies:develop environmentally friendly treatment method,develop relevant policies and standards,and improve the added value of products.
