Background technology
In order to improve oil well produced reducing crude oil viscosity anti-scaling property, need in oil well, to add viscosity reduction, anticorrosion, antiscale chemical agent.At present, have at pumpingh well well head dosing method: the dosing of well head drop pump, Vehicle loaded pump dosing, artificial well head directly pour into dosing.The dosing of well head drop pump need be installed complicated wellhead equipment, and the initial stage has high input, and the later stage needs the professional to safeguard the drop pump; The Vehicle loaded pump dosing needs Vehicle loaded pump and than long lines, every mouthful of well only need add 5～10 hydrargyrum oxydatum crudum agent at every turn, and well head dosing construction is loaded down with trivial details, time-consuming.
The utility model content
The purpose of this utility model is: provide a kind of oil well annular space band to press manual doser, can for oil well adds chemical agent, save energy and reduce the cost under oil well band pressure situation, reduce cost, improve safety.
The technical solution adopted in the utility model is: oil well annular space band is pressed manual doser, mainly is made up of ball-and-seat, piston cylinder, piston, screw rod, handwheel, chemical agent case and pipeline, and the chemical agent case has pipeline to connect the piston cylinder bottom inlet; It is characterized in that: on the pipeline of chemical agent case and piston cylinder bottom inlet, be connected with ball-and-seat; On piston cylinder outlet at bottom pipeline, be connected with ball-and-seat; Piston is arranged in the piston cylinder, be connected with screw rod on the top of piston, be connected with nut on the screw rod, nut is fixed on the upper end cover center of piston cylinder, is fixed with handwheel in the end of screw rod.
Piston cylinder outlet at bottom pipeline connects the annulus logging valve of well recovery tree.Described pipeline is a flexible pipe.What adopt being connected of piston and screw rod is to flexibly connect.
The beneficial effects of the utility model: the utility model oil well annular space band is pressed manual doser, and is on probation by on-the-spot dosing, can satisfy the requirement that oilfield anti-corrosion anti-scale annular space band is pressed dosing.Volume is little in light weight, and 25 kilograms of body weight are easy to move; A dosing cycle simple to operate is 10 minutes; Simple installation, Operating Pressure, safe and reliable; Artificial construction's energy-conserving and environment-protective.The annular space band is pressed dosing efficiency of construction height.The dosing operating expenses will reduce by 50%.
Description of drawings
Fig. 1 is that the utility model oil well annular space band is pressed manual doser and oil well syndeton schematic diagram.
Among the figure, 1. production tree, 2. oil recovery valve, 3. annulus logging valve, 4. sleeve pipe, 5. oil pipe, 6. ball-and-seat, 7. piston cylinder, 8. piston, 9. screw rod, 10. handwheel, 11. chemical agent casees.
The specific embodiment
Embodiment 1: pressing manual doser with an oil well annular space band is example, and the utility model is described in further detail.
Consult Fig. 1.The utility model oil well annular space band is pressed manual doser, mainly is made up of ball-and-seat 6, piston cylinder 7, piston 8, screw rod 9, handwheel 10, chemical agent case 11 and pipeline.Chemical agent case 11 bottom line connect the inlet of piston cylinder 7 bottoms.On the pipeline of chemical agent case 11 and piston cylinder 7 bottom inlets, be connected with a ball-and-seat 6; On piston cylinder 7 outlet at bottom pipelines, be connected with a ball-and-seat 6; Piston 8 is arranged in the piston cylinder 7, be connected with screw rod 9 on the top of piston 8, what adopt being connected of piston 8 and screw rod 9 is to flexibly connect, as: there is ring-shaped step screw rod 9 ends, and hundred million annular glands are arranged on ring-shaped step, and gland is fixed on piston 8 upper surfaces.Be connected with nut on the screw rod 9, nut is fixed on the upper end cover center of piston cylinder 7, is fixed with handwheel 10 in the end of screw rod 9.What pipeline adopted is flexible pipe.
Summary oil well annular space band is pressed being connected and use of manual doser and oil well.Consult Fig. 1.Oil recovery valve 2 is arranged at the top of production tree 1, is connected with pipeline of oil production on the oil recovery valve 2.Pipeline of oil production and oil pipe 5 UNICOMs, well liquid flows out from pipeline of oil production.Form annular space between the sleeve pipe 4 of production tree 1 bottom and the oil pipe 5, annulus logging valve 3 and annular space UNICOM.Piston cylinder 7 outlet at bottom pipelines connect the annulus logging valve 3 of well recovery tree 1.Rotating handwheel 10 drive pistons 8 pumps in piston cylinder 7.Liquid preparation when piston 8 moves upward in the suction chemical agent case 11 arrives; Piston cylinder 7 internal pressures increase when piston 8 moves downward, when pressure surpassed the pressure of oil well, the liquid preparation in the piston cylinder 7 was extruded out from the outlet of piston cylinder 7, and liquid preparation can join band by pipeline and press in the oil well, and realization oil well annular space band is pressed dosing.
