油田封井器试压后的污水中含液压油、泥沙等废油、废渣。为了将污水中的废油、废渣分离、收集起来,使污水达到排放标准,本文研究了封井器试压后排出的废水除油除渣工艺,选用了相关的配套设备。试验结果表明,该工艺能较好地去除污水中的废油和废渣,分离后的水达到相关排放标准。本文的研究为其它含油、泥沙和水的液-液-固分离提供了参考。
After the oilfield seal blower sewage containing hydraulic oil, sediment and other waste oil, waste. In order to separate and collect the waste oil and the waste residue in the sewage, the sewage is discharged to the discharge standard. In this paper, the process of degreasing and slag removal of waste water discharged after pressure test of the blowout preventer is studied, and the related auxiliary equipment is selected. The test results show that the process can remove the waste oil and waste residue well, and the separated water meets the relevant discharge standards. This study provides a reference for other liquid-liquid-solid separation of oil, sediment and water.
