Definitions
- One method is to inject a viscous solution of polymers, particularly polyacrylamide, to mobilize a larger volume of the field.
- the injected polyacrylamides are sensitive to the mechanical and chemical degradation of the molecular weights, which requires precise handling to maintain their effectiveness.
- the polymers are in powder form, which is dissolved in water at a fairly high concentration, to reduce the size of so-called maturation tanks, that is to say of dissolution. Indeed, the dissolution time of these powders is of the order of 1 hour.
- the concentration of these solutions is 10 to 20 grams / liter with high viscosities (1,000 to 10,000 cps).
- this stock solution should be diluted to 1 to 3 grams per liter to be injected.
- Various methods are used to avoid mechanical degradation by a sudden drop in pressure, to adapt the injection pressure to the pressure of the specific well.
- the first is to install a dosing pump per well, and send the stock solution to the top of each well to dilute it with the injection water.
- the second method consists in diluting the stock solution on the dissolution platform, and sending this diluted solution into each well by separate pipelines.
- the third method is to completely dilute the stock solution by the injection water set, and to use the water injection lines. This method requires the lowest investments. In this case, the water pump will be set above the pressure of the well with the highest pressure, and the pressure on the other wells will need to be reduced, which normally corresponds to a deterioration that increases as much as the pressure differential is larger. To avoid this degradation, specific pressure reducers are used which must not degrade the polymer.
- the optimal speed is of the order of 10 meters / second.
- it is possible to modulate the pressure drop by cutting the tube into various lengths that can be fed or passed through.
- the vortex pressure reduction with several needle valves can each create a pressure drop of about 5 bars with minor degradation (document US2016 / 0168954).
- valve heads can be equipped with hydraulic motors in series, allowing the same opening on all the valves with a single adjustment.
- These systems are heavy for the first, not flexible for the second, rather expensive for the third.
- the petroleum companies' demand is with a maximum pressure drop of about 50 bar, with little degradation, with a modulation per well of about 10 bar, and a possibility of supplying wells whose pressure varies over time. with a simple and cheap device.
- the material must therefore be very flexible and easy to handle.
- each pressure reducer is made by at least one valve, preferably 2 valves, each creating a pressure drop of up to 5 bars without significant degradation of the polymer;
- the subject of the invention is an apparatus for regulating the injection pressure of a polymeric aqueous solution in a petroleum well, said apparatus consisting of:
- At least one pressure modulation valve permitting a maximum pressure drop of 5 bar per valve, practically without mechanical degradation, the said valve (s) being connected in series with;
- a vortex module being a section of tube, closed at one of its ends by a cap pierced with a hole, and adapted to be inserted into the tube;
- the apparatus having the purpose of being able to reduce the pressure up to 100 bars with a total mechanical degradation of less than 10%.
- mechanical degradation is meant the degradation of the polymer in the solution injected into the well as measured by the drop in viscosity of the solution after passing through the pressure regulating apparatus.
- the hole of the lid has a diameter of between 10 and 25 mm.
- the valves are needle or needle type, although other types of valves also work.
- the hole is preferably in the central position.
- Each vortex module may be positioned such that the hole is downstream or upstream of the flow.
- the vortex modules are all positioned in the same direction with the hole downstream of the flow of the aqueous polymeric solution.
- modules may, for example, consist of a perforated washer associated with pieces of 10 cm tube.
- the tube contains between 4 and 20 vortex modules. This allows for losses of up to 20 bar (4 modules), and up to 100 bar (20 modules).
- the vortex modules are able to be inserted into the tube.
- the outer diameter of the vortex modules is slightly less than the inside diameter of the removable tube. Preferably, it is less than 1 mm.
- the pressure modulation valve (s) may be positioned (s) upstream or downstream of the tube containing the vortex modules.
- the inner diameter of the tube is between 1.27 cm (1 ⁇ 2 inch) and 10.16 cm (4 inches), preferably between 1.27 cm (1 ⁇ 2 inch) and 7.62 cm (3 inches).
- this equipment can be used in underwater injection, on which the two modulation valves are controlled from the surface by a hydraulic motor, and the tube itself will be fixed by quick clamps, allowing disassembly, a change in the number of modules, a reassembly in a fairly easy way.
- one or more valves can be installed to modulate the pressure and to restrict or widen the control zone.
- the subject of the invention is also a process for reducing the injection pressure of an aqueous polymer solution as a function of the pressure of the well, using the apparatus according to the invention, in an enhanced oil recovery process.
- the pressure drop created in a valve or in a vortex module is at most 5 bars, preferably between 1 and 5 bar.
- Figure 1 shows a schematic view of the pressure regulating apparatus connectable in series to the main line.
- the apparatus comprises successively two valves (1) allowing a maximum reduction of pressure of 5 bars each, two pressure gauges (2) allowing a pressure control, and a removable tube (3) containing 10 vortex modules (4), each allowing a maximum pressure reduction of 5 bar.
- this device is capable of regulating the pressure up to 60 bar.
- FIG. 2 is a diagrammatic view of a part of the removable module (3) of 60 mm internal diameter containing two vortex modules (4) 100 mm long, 59 mm outside diameter, 50 mm inside diameter; each provided with a central hole with a diameter of 14 mm.
- a pressure reducer is constructed comprising: Two 2-inch needle valves with pressure gauges allowing adjustment between 1 and 5 bars of pressure drop;
- the covers are pierced at 14 mm of passage to create a vortex pressure drop of 5 bar for 19 m3 / hour.
- the tube is put in 5 modules, and the pressure can be modulated with the two valves from 125 to 135 bars.
- the tube is put in 6 modules, and can be modulated from 120 to 130 bars.
- the degradation observed is less than 5% even with a pressure difference of 50 bars.
