浅究钻井废弃物无害化处理技术

Harmless Treatment of Wasted Drilling Fluid

针对重庆气矿五宝浅15井、五宝浅9井、五宝浅12井、东浅5井的废弃钻井液进行了室内无害化处理。利用Fenton试剂法处理钻井液废水,处理后的水达到国家一级排放标准。确定了固化剂体系组成及最佳用量:20%水泥,10%电石渣,1%水玻璃,6.3%硫酸铝,0.7%硫化钠,0.3%磷酸钠。在此条件下,废弃钻井液的固化处理效果最好,其固化体浸出液达到排放标准。此固化处理方法成本低廉,操作简单,具有较好的经济与环境效益。

In this paper,it was carried out indoor harmless treatment of wasted drilling fluid of Wubaoqian15#、Wubaoqian 9#、Wubaoqian12#、Dongqian5#. Using Fenton method to treat the wasted drilling water,the treated water meets the national emission standard. Make sure the composition of the system and the best dosage of the curing agent: 20% cement,10% carbide slag,1% sodium silicate,6. 3% aluminum sulfate,0. 7% sodium sulfide and 0. 3% sodium phosphate. Under these conditions, the treatment is the best and the solidation can meet the emission standard. This treatment method is less cost,simple operatiion and having best economic and environmental benefits.
