甘谷驿油田压裂返排液回用技术和室内评价

Reuse technology and indoor evaluation of fracturing and discharging fluid in Ganguyi Oilfield

为了避免压裂返排液对甘谷驿油田采出水对水处理站系统的冲击,甘谷驿油田建设了压裂返排液处理站,处理后的返排液用于回用配液。室内对处理后的回用水水质和配液情况进行评价,回用水的水质能够满足配置压裂液的用水标准。同一条件下,回用水配置的压裂液体系较清水配置的压裂液体系性能接近,不影响压裂液性能和使用效果。

In order to avoid the impact of fracturing fluid on the water treatment station system in Ganguyi, Ganguyi Oilfield has been constructed a fracturing fluid treatment station, and the treated back discharge fluid is used for reinjection. Indoor water quality and distribution of water reuse were evaluated, and water quality of water reuse could meet the standard of water used for fracturing fluids. Under the same condition, the fracturing fluid system with water injection configuration is similar to that of the fractured fluid system, which does not affect the performance and the use effect of the fracturing fluid.
