摘要
针对微生物处理、热脱附、热清洗、焚烧和萃取等含油钻屑处理技术存在普适性差、资源浪费、技术不成熟或投资较高等问题,探究更为高效、性价比高的含油钻屑处理技术。分析了国内外含油钻屑处理的法律法规,对目前国内外常用的含油钻屑常规处理技术、资源化利用技术,及其应用现状进行了综述,通过对各类技术的对比分析,提出含油钻屑处理技术高效低成本、"高价值"基础油回收与固相残渣的资源化利用、工厂化和随钻化处理的双极发展趋势,对油基钻井液中的基础油、水进行回收利用,处理后的固相可以转化为可利用的资源。
Current technologies regarding oily drilling cutting treatment,such as microbial treatment,thermal desorption,thermal cleaning,incineration and extraction,have met with problems including poor universality,waste of resources,immature technology or high investment.In this study,current technology and application status commonly used both at home and abroad were reviewed,along with the corresponding laws and regulations,so as to explore a more efficient and cost-effective oily drilling cuttings treatment technology.Based on the comparisons among various technologies,the developing trends including recycling of high value base oil, resource utilization of solid residues,high efficiency and low cost treatment of oil-based drilling cuttings,and the bipolar ideas of factory treatment or deal while drilling were discovered.A technology roadmap with the recycling of oily drilling fluids,base oils and water,following the resource utilization of solid phase were recommended.
