Above-mentioned oil conservator (13) shell communicates with the welding of sand discharger (12) shell by swash plate (14), is convenient to sand grains and crude oil Gravity Separation, accelerates sand setting speed.
Above-mentioned sand discharger (12) can be selected the manual sediment outflow mode of spiral for use, such sand discharger (12) comprise the shell that links to each other with oil conservator, helical axis (7-1) and on helicla flute (9), and be installed in the hand crank (7-2) of helical axis one end and the sediment outflow pipe (11-1) of the other end, hand crank shakes helical axis, the oil-sand that is deposited on the bottom is gone up helicla flute (9) release by helical axis (7-1), discharge from sediment outflow pipe (11-1), the sealing flange of the sediment outflow mouth of pipe (11-2) is in sealing state usually, opens during sediment outflow.
For guaranteeing that sediment outflow helical axis (7-1) goes slick, in the sand discharger shell, the two ends spindle nose has also designed the end face bearing (10-2) that has sand block plate (10-1), is installed on the bearing support (10-3).
In the both sides, front and back of sand control device shell 4 both-end bearings (8) are installed altogether, package unit is installed steadily, move lifting conveniently, and can adjust the setting height(from bottom) of sand control device.
The utility model is applied to flowing well sand control, the sediment outflow that shakes out serious.Prior art is to be used for pumpingh well down-hole sand control, because pumpingh well has down-hole string, can be with sand control pipe the sand production in oil retaining in the tubing string outside, and the down-hole shakes out and just can not enter fuel transfer system like this.Because flowing well does not have downhole pump, when sand production in oil is serious, takes sand from the liquid that oil well production is come out, if enter fuel transfer system, will cause oil transfer pump sand card and big pot of oil storage sand setting, influences crude oil production.Use this device and can carry out flowing well well head sand control, sediment outflow effectively, help the conveying and the processed of crude oil.
