Definitions

  • the invention relates to a continuous mixing device intended for mixing in particular high viscosity crude oil with at least one other less viscous fluid in order to obtain a mixture of viscosity much lower than said crude oil, the mixture being more efficiently displaced by pumping by conventional systems.
  • Patent application FR-2656035 discloses a device for pumping a liquid of high viscosity, but the entire volume of the working fluid is mixed with crude oil. In addition, this installation does not describe a dynamic and continuous mixing device placed upstream of the pump.
  • the invention advantageously improves the prior techniques in particular by the use of a mixing device separate from the pump and allowing an appropriate adjustment of the physical characteristics of the mixture supplied to the inlet of the pump.
  • the object of the present invention therefore relates to a continuous mixing device comprising a body in which fluids circulate between an inlet and to an outlet of said body and at least two fluids of different viscosities entering through said inlet.
  • the device comprises a rotary shaft comprising at least two blades and it is adapted to supply at the outlet of said body a mixture of said two fluids, said mixture having a viscosity lower than that of the most viscous inlet fluid.
  • the profile of the blades can be such that without circulation, the rotation of the blades provides a reaction force substantially parallel to the axis of rotation and directed in the same direction as the flow when the latter is established.
  • the profile of the blades can be such that, without circulation, the rotation of the blades does not provide a reaction force of significant magnitude parallel to the axis of rotation.
  • the device can comprise at least a set of three stages of blades, each stage being able to consist of at least two blades having the same cylindrical volume of revolution.
  • the stages can be offset by 120 ° relative to the axis of said shaft and the cylindrical volumes generated by the revolution of each stage can be substantially adjacent.
  • the device can comprise four assemblies and said stage can comprise two blades arranged at 180 °.
  • the shaft can be linked in rotation with the shaft of a hydraulic pump and the outlet of said body can lead to the suction of said pump.
  • the pump can be driven in rotation by a hydraulic motor, itself being able to be driven in rotation by the injection of a pressurized fluid.
  • Part of the pressurized fluid injected into said motor can be led to the inlet of said body.
  • the body of the device can advantageously include deflectors whose internal edge is substantially tangent to the volume of revolution of the blades.
  • the invention also relates to a method of pumping a high viscosity fluid in which said fluid is supplied as well as at least one other fluid of lower viscosity to the inlet of a mixing device according to the invention, the mixture at the outlet of said body being led to the suction of a pump.
  • a part of the working fluid can be brought to the inlet of said body, said working fluid being injected under pressure to rotate the hydraulic motor for rotating the pump and the device.
  • the invention also relates to the use of the mixing device according to the invention in an installation for pumping crude oil with high viscosity in a well comprising a casing.
  • the installation comprises a raw material inlet duct at the inlet of said device, a duct connecting the outlet of said device to the suction of a pump, a hydraulic motor for rotating the pump and said device, a duct for injection of the working fluid connecting an injection installation to the surface and the engine, a pump outlet pipe bringing the mixture to the surface and an engine outlet pipe bringing some of the engine fluid to the surface, the other part being brought to the entry of said device by another conduit.
  • a single duct can go up said part of the working fluid and said mixture and on the surface this duct can communicate with an installation for separating in particular crude oil and the working fluid.
  • Figure 1 shows a partial sectional view of the mixing device.
  • Figure 2 shows a perspective of the rotating shaft of the mixer to better describe the respective arrangement of the blades.
  • FIG. 3 represents a graph giving the viscosity of the oil and of the mixture obtained as a function of the temperature.
  • FIG. 4 represents the diagram of a crude oil pumping installation comprising the mixer.
  • Figure 5 shows a variant of the previous pumping installation.
  • Figure 6 shows another variant of the pumping installation.
  • the mixer 1 is incorporated into a casing 12 secured to the body of the pump not shown in this figure.
  • the conduit 8 puts the crude oil reserve in communication with the inlet 2 of the body 17 of the mixer 1.
  • An orifice 9 puts the channel 10 in communication with the inlet 2 of the mixer.
  • the channel 10 is in particular located in the wall of the casing 12.
  • the outlet 3 of the body 17 of the mixer 1 communicates with the inlet 13 of the centrifugal pump, the first wheel of which is referenced 14.
  • a cylindrical shaft 4 is guided at its two ends by the bearing 6 and a connection means 5 with the shaft of the centrifugal pump.
  • the shaft 4 comprises pairs of blades 7 and 7a, symmetrical with respect to the axis of the shaft 4 and located in the same section.
  • the shaft is equipped with twelve pairs of blades arranged along the length of the shaft so that the upper edge of a blade is substantially in the same section as the lower edge of the blade adjacent.
  • each volume of revolution generated by the rotation of a pair of blades is substantially adjacent to the next.
  • the blades are inclined at an acute angle i relative to the axis of the shaft oriented in the direction of the flow, that is to say in the direction of arrow 15, the direction of rotation of the 'shaft being indicated by arrow 16.
  • This mode of orientation of the blades relative to the direction of rotation of the shaft and the direction of circulation of the fluids in the mixer provides a reactive force on the shaft in the same direction as the circulation.
  • This force is the axial component of the result of the reactive forces on each blade.
  • the rotation of these propellers that constitute all of the blades tends to push the flow in the opposite direction to its circulation.
  • the mixer can be compared to a repelling propeller. This arrangement promotes the action of stirring the fluids in the mixer to obtain a homogeneous mixture.
  • the section of the blades is not inclined as above.
  • the blades may in particular be flat and their width disposed parallel to the axis of the shaft, that is to say that the angle i is zero.
  • the blades can also be of substantially cylindrical shape. More generally, it can be said that in this embodiment the mixer will neither be repellent against flow, nor attractive. The mode of action is then close to a shearing action on the circulating fluid vein.
  • the blades of the continuous mixer cannot have an action providing an acceleration of the flow, such as an attractive propeller, or a centrifugal pump wheel.
  • the mixer of our invention is totally different from a compression element, whether this is a pump element, a booster element or a priming element.
  • the mixer of our invention provides a pressure drop, generally minimal but still noticeable.
  • the pairs of blades are distributed over the periphery of the shaft with an angular offset of 120 °. So the fourth blade has the same angular position as the first then defining a set of three pairs of blades.
  • the embodiment shown therefore comprises four of these sets.
  • the number or the arrangement of the blades are different. Indeed, depending on the nature of the fluids and their flow in the mixer, it may be necessary to increase or decrease the number of blades, and even to have more than two blades in the same cross section. In this case, they will be distributed regularly around the periphery of the tree.
  • the value of the angle i can be variable but less than or equal to 90 °, taking into account the references indicated above.
  • Figure 2 shows in partial perspective the arrangement thus obtained in the preferred embodiment.
  • the body 17 of the mixer comprises deflectors 11 arranged along generatrices of the cylindrical interior volume of the body.
  • This embodiment comprises four deflectors distributed at 90 °. These deflectors can be produced in multiple and diverse ways, their main role being to straighten the fluid stream by promoting the turbulence created by the blades while allowing the fluid to circulate between the inlet and the outlet.
  • Curve A relates to anhydrous heavy crude oil.
  • Curve B gives the viscosity of an emulsion consisting of 60% of the heavy petroleum of curve A and 40% of water, the assembly having passed through the mixing device of the invention with a flow rate of 2500 l / hour and for a mixer rotation speed of 3000 rpm.
  • Curve C represents the viscosity of a mixture obtained in a container from the same proportion of crude oil and water.
  • FIG. 4 represents a pumping installation lowered into a well 20, generally cased by a casing 21.
  • the well is in communication with a viscous oil deposit. This oil flows into the well.
  • the installation pump is immersed in petroleum 22 to a suitable depth depending in particular on the characteristics of the deposit, the configuration of the completion and the static and dynamic level of the effluent.
  • the upper part 27 is made up of concentric tubulars, assembled to the surface where are located in particular an installation 28 for injecting the working fluid, an outlet from a collecting pipe 29 for a portion of the working fluid, a line 30 for collecting the compressed mixture, an outlet from a degassing line 31 and a departure from the line 35 for injecting the working fluid.
  • Line 35 connects the injection installation 28 to the inlet 33 of the hydraulic motor.
  • Line 31 is an annular line defined by the well and the outside of the tubulars and casings of the pumping installation. This pipe directly connects the crude oil reserve to the surface and allows the gas to be collected on the surface while letting the oil degas naturally. The more the fluid 22 is degassed, the better the efficiency of the pumping installation.
  • Line 30 connects the outlet of pump 34 to the surface.
  • Line 29 connects outlet 32 of the hydraulic motor.
  • a conduit 37 connects the outlet 32 of the motor to the inlet 38 of the mixer 24.
  • the supply conduit 23 comprises two concentric tubes 40 and 41 forming baffles in order to promote the degassing of the crude. This enters the conduit through the perforations 39, passes through the annular of the tubes 40 and 41 and then back up into the tube 41 to arrive at the inlet 38 of the mixer.
  • the motor 26 can be of the turbine or volumetric type, for example according to the Moineau principle.
  • the circulation of the working fluid in the engine can be done from bottom to top or vice versa.
  • the pump can be of the single or multi-stage centrifugal type or of the volumetric type for example according to the Moineau principle.
  • the dimensions of the concentric triple completion lowered into the casing 21 in casing 9 5 / 8 ⁇ can be: casing or tubing 7 ⁇ for the pipe 30, tubing 4 1 / 2 ⁇ or 5 ⁇ for the pipe 29 and tubing 2 ⁇ or 2 7 / 8 ⁇ for the pipe 35.
  • the installation is simplified from the point of view of the number of pipes compared to the preferred embodiment of Figure 4 where three concentric pipes 30, 29, 35 are used in the well 20 , that is, a triple completion.
  • a packer type sealing element 45 between the oil supply pipe and the walls of the well. This packer isolates the reservoir area and allows the use of the annular pipe 46 above said packer for the ascent of the mixture from the outlet 34 of the pump to the surface.
  • the completion then comprises two tubes 29 and 35 for respectively raising a portion of the working fluid and injecting the motor fluid.
  • FIG. 6 A second variant of the pumping installation is shown in FIG. 6. This involves bringing together the pumped mixture and the part of the working fluid.
  • the outputs 32 and 34 respectively of the motor and of the pump communicate in a single line 47.
  • This line is connected at the surface to an installation 48 adapted to the separation of crude oil, working fluid and other fluids from the mixture if those - these are not the working fluid.
  • a pipe 49 collects the working fluid to recycle it in the injection installation 28.
  • the lines 29, 30 and 35 may not be concentric, in fact the prior art knows the multiple non-concentric completions, that is to say using parallel tubes in the well 20.
  • this lower viscosity fluid admitted to the inlet of the mixer through the orifice 9 is different from the working fluid used for the motorization of the pumping installation.
  • this lower viscosity fluid may include several constituents adapted to promote mixing. In this case we can use another separate supply line and connected to the surface.
  • the fluid (s) mixed with the high viscosity fluid may be of mineral or organic origin.
  • the mixture obtained by the mixer according to the invention will be an emulsion and / or a dilution.
  • the proportions of the constituents of the mixture can be variable depending on the characteristics of the deposit and the nature of the fluids in place.
  • means for regulating the flow rate of fluid injected at the inlet of the mixer are in particular located between the outlet of the engine and the pipe 10 or 37.
  • the well has an inclined portion and even may be close to the horizontal.
  • the pumping installation is then generally lowered into a part of the well which is strongly inclined.
