Abstract
The utility model relates to an electric submersible pump used for oil extraction in an oil filed, particularly to a scale prevention separator of a centrifugal pump. The lower end of a separator shaft of the device penetrates a scale prevention base, scale prevention sheets and scale prevention spacers are stacked alternately to form a scale prevention sheet group, the scale prevention sheet group is placed in the scale prevention base and mounted on the separator shaft in a sleeving manner, an inducer cavity is connected at the upper end of the scale prevention base through screw threads and compacts the scale prevention sheet group, the upper end of the inducer cavity is connected with a casing of the separator through screw threads, and a duct is formed in the scale prevention base at the lower end of the scale prevention sheet group. The scale prevention separator prevents the centrifugal pump from scaling without increasing the unit maximum external diameter, and overcomes the defects that the oil well construction difficulty is increased because the present scale prevention equipment needs to be additionally equipped with an air deflector larger than the electric pump unit in maximum external diameter.
Description
Technical field:
The utility model relates to a kind of submersible electric pump of oil field oil recovery usefulness, particularly a kind of centrifugal pump antiscale separator.
Background technique:
At present, the oil field employed submersible electric pump pumping of recovering the oil partly comprises separator and centrifugal pump, and the well liquid that carries out after the Oil-gas Separation through separator is pumped into ground behind centrifugal pump.Because the complicated component of well liquid, the liquid of the centrifugal pump of flowing through may fouling on the impeller of centrifugal pump and guide wheel.General separator only possesses the function that well liquid is separated with gas, and the well liquid of the centrifugal pump that can not guarantee to flow through can fouling in centrifugal pump, and fouling tends to cause electric pump unit cisco unity malfunction and the shutdown of breaking down.At present; Certain prevents the equipment of oil well well liquid fouling can be employed in the installation of electric pump unit bottom; But this equipment need add the air guide sleeve greater than electric pump unit maximum outside diameter; Could guarantee enough to enter into centrifugal pump, increase the difficulty of well construction, and had a lot of production safety hidden danger through the well fluid power after the antiscale device processes.
The model utility content:
The technical problem that the utility model will solve provides a kind of centrifugal pump antiscale separator, and this device has realized preventing the centrifugal pump fouling, and need not increase the maximum outside diameter size of unit.Overcome existing antiscale equipment and need add air guide sleeve, increased the deficiency of well construction difficulty greater than electric pump unit maximum outside diameter.
The technological scheme that the utility model is taked is: a kind of centrifugal pump antiscale separator; Comprise decoupler shaft; Separator intersection guide wheel, separator rotor, separator turbine, separator guide wheel, separator impeller, inducer are sleeved on the decoupler shaft from top to bottom successively; Decoupler shaft places in the separator shell body, and the separator upper connection is threaded on the separator shell body; The decoupler shaft lower end is through on the antiscale base; Antiscale sheet and antiscale partition are stacked alternately and form antiscale sheet group; Antiscale sheet group places in the antiscale base and is sleeved on the decoupler shaft; The inducer cavity is threaded in antiscale base upper end and compresses antiscale sheet group, and the separator shell body that is threaded on the inducer cavity has the duct on the antiscale base of antiscale sheet group lower end.
The beneficial effect of the utility model is: the utility model is installed the mode of antiscale sheet group owing to having adopted, thereby has the function that prevents the centrifugal pump fouling, need not increase the maximum outside diameter size of unit simultaneously.
Description of drawings:
Below in conjunction with accompanying drawing and embodiment the utility model is done further detailed explanation.
Accompanying drawing is the structural representation of the utility model.
Embodiment:
Shown in accompanying drawing; A kind of centrifugal pump antiscale separator; Comprise decoupler shaft 1; Separator intersects guide wheel 12, separator rotor 10, separator turbine 9, separator guide wheel 8, separator impeller 7, inducer 6 and is sleeved on successively from top to bottom on the decoupler shaft 1, and decoupler shaft 1 places in the separator shell body 11, the separator upper connection 13 that is threaded of separator shell body 11 upper ends; Decoupler shaft 1 lower end is through on the antiscale base 2; Antiscale sheet 3 is stacked alternately with antiscale partition 4 and forms antiscale sheet group; Antiscale sheet group places in the antiscale base 2 and is sleeved on the decoupler shaft 1; Inducer cavity 5 is threaded in antiscale base 2 upper ends and compresses antiscale sheet group, and the inducer cavity 5 upper ends separator shell body 11 that is threaded has the duct on the antiscale base 2 of antiscale sheet group lower end.
During the utility model work; Well liquid can directly get into the utility model from underground bushing; The well liquid that gets into the utility model at first carries out scale control treatments through antiscale sheet group; And then enter into centrifugal pump after the process separator Oil-gas Separation, thereby under the situation that does not change unit maximum outside diameter size, possessed anti-scaling property.
It is understandable that; More than about the specific descriptions of the utility model; Only be used to the utility model is described and be not to be subject to the described technological scheme of the utility model embodiment; Those of ordinary skill in the art should be appreciated that still and can make amendment or be equal to replacement the utility model, to reach identical technique effect; As long as satisfy the use needs, all within the protection domain of the utility model.
