The reuse technology study about drilling wastewater in Hangjinqi area
In order to meet the severe environmental protection requirements in Hangjinqi area,reduce drilling costs and improve exploration and development benefits,the ion content was analyzed in drilling wastewater,and the mechanism that the wastewater could not be reused directly was clarified.According to the mechanism of ion chemical precipitation and particle flocculation,the wastewater treatment scheme of improving pH value-oxidation-ion capture-flocculation was formulated,and the experimental study on wastewater reuse was carried out.The experiment showed that the treated wastewater had little effect on the per-formance of drilling fluid after being reused into drilling fluid.The technology was applied in the field.The reuse effect of wastewater after be treated was good,and the goal of reducing costs and increasing efficiency was achieved.
