海上废弃钻井液的无害化处理方法研究

随着中国石油行业快速发展,钻井井场产生废弃钻井液增多,大量废弃钻井液对海洋陆地环境造成严重污染,对废弃钻井液无害化处理对生态环保具有重要意义。随着对环保的重视,钻井中产生的钻井液处理受到关注。废弃钻井液是海上油田开发中产生的主要污染物,其含有多种有害物质,无害化处理对保护海洋生态环境健康具有重要意义,本文综述国内外废气钻井液生物毒性评价,指出建立多生物能级的钻井液毒性评价方法。

Study on harmless treatment of waste drilling fluid at sea

With the rapid development of China’s petroleum industry,more and more waste drilling fluid is produced in the well pad,A large number of waste drilling fluid causes serious pollution to the marine and land environment,and the harmless treatment of waste drilling fluid is of great significance to the ecological and environmental protection.With the attention to environmental protection,the treatment of drilling fluid produced in drilling is concerned.Waste drilling fluid is the main pollutant produced in offshore oilfield development,It contains a variety of harmful substances,and harmless treatment is of great significance to protect the health of marine ecological environment,In this paper,the biological toxicity evaluation of waste gas drilling fluid at home and abroad is reviewed,and the establishment of multi biological level evaluation method of drilling fluid toxicity is pointed out.
