Step 3, the silt particle after desanding is for the first time carried out to sedimentation separation separate with quiet liquid, realize desanding for the second time, export the drainage-fluid after desanding for the second time, get rid of silt particle after desanding for the second time through sediment outflow bag and sand flash valve.
In addition, for the Produced Liquid (containing sand oil gas aqueous mixtures) in above-mentioned many hydrocyclones and oil field, the another process of utilizing many cyclone desanding devices of the utility model to carry out desanding, as shown in Figure 5, comprising:
Step 1, feed liquor header 2 are given each boundling eddy flow socket 1 by height containing the uniform distribution of sand oil gas aqueous mixtures by liquid feed valve 4.
First feed liquor header 2 is given each boundling eddy flow socket 1 containing sand oil gas aqueous mixtures through liquid feed valve 4 uniform distributions by height, by annular feed liquor distribution pipe 12, evenly enters cyclone pipe 11 with symmetry direction.This enforcement is 4 boundling eddy flow sockets 1 preferably, are arranged symmetrically with.
Step 2, the high liquid-solid rotational flow separation containing sand oil gas aqueous mixtures process cyclone pipe 12, carry out desanding for the first time, and the low sand oil gas aqueous mixtures that contains after desanding is for the first time inputed to drain pipe 5.
The many cyclone pipes that are arranged in parallel 11, drag sand mechanism according to solid-liquid density difference and drainage, and height is carried out to liquid-solid rotational flow separation containing sand oil gas aqueous mixtures, realize desanding for the first time.The low sand oil gas aqueous mixtures that contains after desanding is discharged through drainage tube 8, enters next production unit.
Silt particle after step 3, desanding for the first time enters sand storage chamber 32, carry out sedimentation separation, supernatant (supernatant is lower than the low sand content containing sand oil gas aqueous mixtures after desanding for the first time) flow through the first baffle plate 311, second baffle 312 and quiet liquid chamber 33 after sedimentation separation, carry out quiet liquid separation, realize desanding for the second time, (drainage-fluid is lower than the sand content containing sand oil gas aqueous mixtures of supernatant for drainage-fluid after desanding for the second time, it is minimum to be that sand content is down to) export through drainage tube 8, the silt particle after desanding is got rid of through sediment outflow bag 6 and sand flash valve 7 for the second time.
After total underflow opening 14 is deposited to silt particle sand storage chamber 32 and precipitates in this chamber, the supernatant of clarifying out from the overhead stream of sand storage chamber 32 through the first baffle plate 311, enter the bottom of clean liquid chamber 33 from second baffle 312, and prolong with the catercorner direction of drainage tube 8 at clean liquid chamber 33 tops and flow to this drainage tube 8.Thereby, realized in sand storage chamber 32 and set up liquid flow, and isolated silt particle in boundling eddy flow socket 1 has been drawn in sand storage chamber 32 through total underflow opening 14.Supernatant has obtained the longest sedimentation path and maximum sedimentation time in clean liquid chamber 33, makes the sand factor of drainage-fluid be down to minimum.
The silt particle accumulating in sand storage chamber 32 and clean liquid chamber 33 is regularly discharged many hydrocyclones through sediment outflow bag 6 and sand flash valve 7.
In the present embodiment, after step 3, further comprise:
Step 4, low after desanding for the first time and after desanding for the second time mixed containing sand gas-liquid mixture, separate by three phase separator.
