Embodiment
[0012] refer to Figures 1 to 3 Embodiments of the present invention are further described:
[0013] The specific implementation steps of this desanding process are as follows:
[0014] 1) Connect the cyclone desanding device 1 to the wellhead, so that the cyclone desandering device 1 operates with the pressure of the fracturing flowback fluid in the wellbore of the oil well;
[0015] 2) Connect the outlet water from the cyclone sand removal device 1 to the pressure relief and degassing device 2 for gas-liquid separation and filtration and sedimentation; then, the primary water transfer pump 3 is directly pressed into the primary filter device 4 and the sewage tank 5, and left to stand Precipitate for 30-40min;
[0016] 3) After precipitation, the water is directly pressed into the secondary filter device 7 by the secondary transfer pump 6, and the content of sand particles and mechanical impurities in the treated water is below 0.2%;
[0017] 4) Import the treated water in...
