摘　　要：在油气井的钻探过程中,往往会产生大量的废水,特别是南方多雨地区,现场钻井废水的处理一直是一个重要的环保问题,解决好这一问题对保证钻井正常运行十分重要。为此,介绍了川西地区部分井钻井废水的来源,各阶段钻井废水的水质分析以及将钻井废水应用于钻井液中的回收试验,并总结出分阶段针对不同情况回收利用钻井废水的方法。经现场应用,见到了显著的效果。该方法既解决了钻井废水污染问题,又降低了钻井液成本,为绿色钻井提供了重要的方法与途径,具有较高的实用价值。There is normally a large amount of sewage produced during oil/gas well drilling, especially at rainy areas of South China. With awareness of environmental protection increasing, how to handle the sewage is becoming a critical environmental issue on drilling sites. This paper introduced the sources of drilling sewage in west Sichuan basin, analyzed the sewage produced in different drilling stages, and tested on sewage recovery and recycling into drilling fluid. And finally different drilling sewage recycling methods are summarized. The field application results demonstrate remarkable effects. The sewage recycling can not only reduce sewage contamination, but also reduce drilling costs. It is an important and applicable way for environmental-friendly drilling.
