含油钻屑处理技术研究进展与展望

Research and development of oily drilling cuttings treatment technologies

使用油基钻井液在钻井过程中会产生大量含油钻屑,处理不当会对生态环境和人类健康造成危害。世界各国针对含油钻屑的排放制定了严格标准,要求含油钻屑必须处理达标后方可排放。介绍国内外含油钻屑处理的相关法规和标准,对国内外含油钻屑处理技术的主要研究成果及应用现状进行综述,并阐述其技术原理。通过对各类含油钻屑处理技术的归纳总结,明确不同类型处理技术的优缺点,最后对未来含油钻屑处理技术应用研究的发展进行展望。未来含油钻屑处理技术应向着新材料、新装备、新技术的方向发展,以实现含油钻屑的无害化、资源化处理。

The use of oil-based drilling fluids will produce a large amount of oily drilling cuttings in the drilling process.Improper treatments of those cuttings can cause ecological environment problems.Many countries in the world have formulated strict standards for the discharge of oily drilling cuttings,which require that oily drilling cuttings must be treated after reaching the discharging standards.In this paper,the relevant regulations and standards for oily drilling cuttings treatments were introduced,and the main research results and application status of the oily drilling cuttings treatment technology were summarized along with its technical principles.The advantages and disadvantages of different types of the treatment technologies for oily drilling were discussed and clarified,and the research and development of new technologies were prospected.It is concluded that the future oily drilling cuttings treatment technology should develop towards new materials,new equipment,and new technologies to achieve hamless and resourceful treatment of oily drilling cuttings.
