Embodiment 1
[0024] The fracturing fluid flowback fluid waste in the Hailaer block of Daqing Oilfield is transported to the fracturing flowback fluid treatment station by tank truck. The specific process is as follows:
[0025] Step S1: Recover the waste fluid of the fracturing flowback fluid through oil separation to obtain recovered waste fluid.
[0026] The waste liquid of fracturing flowback fluid is unloaded in the waste oil recovery tank, and the waste oil continuously settles and separates to float on the liquid surface. After being recovered by the oil skimmer, the recovered waste liquid is obtained, and transported by the liquid tanker to the combined station for treatment. The oil separation recovery time is 55min.
[0027] Step S2: Degrading the recovered waste liquid to obtain degraded waste liquid.
[0028] The recovered waste liquid enters the oxidation tank through the pipeline from the waste oil recovery tank, and bacteria species are added and a large amount of oxygen is...
Embodiment 2
[0038] The waste fracturing flowback fluid in the Outer Mengtamchag block of Daqing Oilfield is transported to the fracturing flowback fluid treatment station by tank truck. The specific process is as follows:
[0039] Step S1: Recover the waste fluid of the fracturing flowback fluid through oil separation to obtain recovered waste fluid.
[0040] The waste liquid of fracturing flowback fluid is unloaded in the waste oil recovery tank, and the waste oil continuously settles and separates to float on the liquid surface. After being recovered by the oil skimmer, the recovered waste liquid is obtained, and transported by the liquid tanker to the combined station for treatment. The oil separation recovery time is 60min.
[0041] Step S2: Degrading the recovered waste liquid to obtain degraded waste liquid.
[0042] The recovered waste liquid enters the oxidation tank through the pipeline from the waste oil recovery tank, and bacteria species are added and a large amount of oxyge...
Embodiment 3
[0052] The waste fracturing flowback fluid in the Zhaoyuan block of Daqing Oilfield is transported to the fracturing flowback fluid treatment station by tanker truck. The specific process is as follows:
[0053] Step S1: Recover the waste fluid of the fracturing flowback fluid through oil separation to obtain recovered waste fluid.
[0054] The waste liquid of fracturing flowback fluid is unloaded in the waste oil recovery tank, and the waste oil continuously settles and separates to float on the liquid surface. After being recovered by the oil skimmer, the recovered waste liquid is obtained, and transported by the liquid tanker to the combined station for treatment. The oil separation recovery time is 50min.
[0055] Step S2: Degrading the recovered waste liquid to obtain degraded waste liquid.
[0056] The recovered waste liquid enters the oxidation tank through the pipeline from the waste oil recovery tank, and bacteria species are added and a large amount of oxygen is su...
