Abstract
The utility model relates to an oil-field auxiliary device, in particular to an oil-well continuous chemical dosing device which comprises a chemical storage head tank, a chemical dosing pump and an oil-water separator, wherein the chemical storage head tank is located at the top end of an pumping unit frame; an outlet pipeline of the chemical storage head tank is connected with a casing pipe through the chemical dosing pump; an oil pipeline is connected in series with the oil-water separator; an outlet pipeline at the bottom of the oil-water separator is connected to the casing pipe. The oil-well continuous chemical dosing device provided by the utility model is simple in structure and low in investment; the chemical dosing pump can be clicked by virtue of the rest energy of an oil pumping unit to ceaselessly add a viscosity reducer into the casing pipe, the injection rate can be adjusted at will, the viscosity reducer can be diluted by water separated from the oil pipeline so that the viscosity reducer reaches the optimum concentration and the utilization ratio of the viscosity reducer is improved. The oil-field auxiliary device is free of climate limitations and consumes no electric energy in the operational process, saves manpower and material resources and can greatly reduce the load of the oil pumping unit.
Description
Technical field
The utility model relates to a kind of oil field servicing unit, relates in particular to a kind of oil well device for continuously adding medicine.
Background technology
At present, on oil field, generally use deep well pump to recover the oil, because the crude oil of extraction contains higher colloid, asphalitine, on oil field, be commonly called as wax, in the process of crude oil extraction, often cause bar, pipe, the pump wax deposition of oil well, increase the load of oil pumper, serious meeting causes deep well pump normally to work.Tradition is added thinner, takes periodically to add more, regularly injects medicament from the sleeve pipe of oil well, removes a small amount of resin and asphalt of oil well bar, pipe, pump, thereby reduces the load of rod-pumped well.But this method is limited by the mal-condition such as road, sleet, thinner often can not add according to the cycle, and in running, needs to consume human and material resources, and effect is not very good yet.
Summary of the invention
Utility model is intended to for the deficiency existing in background technology, and a kind of oil well device for continuously adding medicine is provided.
The utility model oil well device for continuously adding medicine, comprise drug storage head tank, dosing pump and oil water separator, top, its export pipeline that described drug storage head tank is positioned at oil pumping frame are connected with sleeve pipe through dosing pump, on oil pipeline, be connected in series oil water separator, the outlet at bottom pipeline of oil water separator is connected to sleeve pipe.Described dosing pump is reciprocating plunger pump, and its pump rod supports edge under walking beam on pumping units.
The utility model oil well device for continuously adding medicine, reasonable in design, invest little, can utilize the dump energy of oil pumper to click dosing pump, continual is in sleeve pipe, to add thinner, and injection rate can arbitrarily regulate, can also utilize isolated water in pipeline road, dilution thinner, makes thinner reach optium concentration, improves the utilization rate of thinner.The not climate restriction in running of this device, do not consume electric energy, save human and material resources, and can significantly reduce pumping unit load.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
, be described further oil well device for continuously adding medicine of the present utility model below in conjunction with accompanying drawing 1.
The utility model oil well device for continuously adding medicine, comprise that top, its export pipeline 8 that drug storage head tank 1 described in drug storage head tank 1, dosing pump 2 and oil water separator 3 is positioned at oil pumping frame 4 are connected with sleeve pipe 6 through dosing pump 2, on oil pipeline 7, be connected in series oil water separator 3, the outlet at bottom pipeline 9 of oil water separator 3 is connected to sleeve pipe 6.Described dosing pump 2 is reciprocating plunger pump, and its pump rod supports 5 times edges of walking beam on pumping units.
Elaborate operating principle of the present utility model below: drug storage head tank 1 and dosing pump 2 are positioned over the top of oil pumping frame 4, in beam pumping unit working in reciprocating mode process, utilize the descending dump energy of walking beam on pumping units 5, click dosing pump 2, according to the needs in different condition and period, by adjusting the plunger stroke length of liquid valve and reciprocating dosing pump 2, by-pass cock and chemical feeding quantity, and then realize the continuous dosing to sleeve pipe 6.Blending agent in pipeline road 7 is when by oily-water seperating equipment 3, utilize Gravity Separation principle, free water in blending agent is isolated to a part, by valve and outlet at bottom pipeline 9 by water sprue bushing 6, be used for diluting thinner, make thinner reach applicable concentration, improve the utilization rate of thinner.
