The specific embodiment
Embodiment is described in further detail the utility model below in conjunction with accompanying drawing.
To shown in Figure 5, the degassed liquid distributing device that removes sand of this well head comprises as Fig. 1:
Access tube 1 is used for the crude oil production fluid is sent into lower procedure, and it comprises straight length 11, bend loss 12 and the access section 13 that is connected successively.The crude oil production fluid enters access tube 1 via the access tube entrance that is positioned on straight length 11, enters access section 13 via bend loss 12.In the present embodiment, access section 11 connects following pre-separation tube inlet, and 2 one-tenth 20～30 degree angles of access section 13 and pre-separation pipe.
The second-order separation pipe 3 be arranged in parallel with pre-separation pipe 2, and the top of the second-order separation pipe is provided with the second-order separation tube inlet, and the bottom of the second-order separation pipe is provided with absolute oil outlet 31 and silt outlet opening, and the position of silt outlet opening is lower than the position of absolute oil outlet 31; Silt outlet opening in the present embodiment connects silt discharge pipe 8, and this silt discharge pipe 8 is provided with the valve (not shown).
