ZHONG Zhiying，MA Yao，HU Yuanyuan，ZHU Xinjian(Engineering Technology Research Institute of Xinjiang Oilfield Cmpany)2019，9（1）：01-04

Abstract:With the large-scale application of the volumetric fracturing development model，Xinjiang Oilfield expects a sharp increase in the amount of wastewater in the next five years，of which fracturing and returning fluid accounts for more than 50%of the total operating wastewater.At present，the treatment of operating wastewater in Xinjiang oilfield mainly relies on the centralized treatment station that has been built，because the wastewater treatment process has not been considered during the design of the sewage treatment station.After the operation wastewater is recycled to the sewage treatment system，it will cause a great impact on the system and seriously affect the water discharge index of the sewage treatment system.By analyzing the technical status of wastewater treatment in Xinjiang oilfield，this paper proposes a technical scheme to adapt to the“classification classification” of wastewater in Xinjiang oilfield，which not only realizes the resource utilization of wastewater，but also ensures the stable operation of the sewage treatment system.
