  • such pumps allow better conservation of the pumping energy efficiency under multiphase suction conditions, when the relative quantities of gas and liquid to be recompressed vary.
  • these pumps allow good adjustment flexibility as a function of the suction conditions, in particular by adjusting the flow rate of the working fluid, a short reaction time when the settings are modified, as well as a good ability to pump viscous or corrosive fluids. or forming deposits.
  • the present invention therefore relates to an effluent production device contained in an underwater geological formation comprising at least one drilled well, each of said wells extending from a low end in a hydrocarbon tank to a high end forming a well head located substantially above the seabed soil, at least one head of said wells being connected to a production conduit supplying a treatment zone such that in particular a platform, characterized in that it further comprises a pumping module arranged on the seabed provided with a jet pump connecting the well heads to the production conduit, said hydrocarbon being pumped at the outlet of the heads of well to the storage area by said jet pump.
  • the present invention is particularly advantageous when used with the technique of tools and pumped instruments, such as that commonly designated by the initials TFL (from the Anglosaxon Through Flow Line). Indeed, by this technique, it is possible to set up and remove at will the jet pump (s) to adjust their adjustment parameters or carry out control and maintenance operations.
  • the effluent production device is characterized in that at least one of said wells comprises a jet pump disposed at a given height inside said well so as to pump the effluent from the formation up to 'at the wellhead.
  • Such a device makes it possible to exploit a geological formation in an evolutionary and appropriate manner for each of the wells, in particular when the formation is heterogeneous and has already been exploited and decompressed.
  • a switching device for example, each of the branches of which is connected to a wellhead and the reunification element of which is connected to the jet pump.
  • a line of working fluid coming from the treatment zone supplies the pumping module as well as each of the well heads.
  • the wells drilled each comprise a casing coaxial outside a production tube in which is disposed a jet pump, the production tube being connected at the level of the well head with a branch of the device switch and the annular volume located between the casing and the production tube being connected to the driving fluid line.
  • the drilled wells each comprise a casing in which is disposed a first tube receiving the jet pump for the production of the effluent and connected at the wellhead to a branch of the referral device and a second tube connected at the wellhead with the driving fluid line for the supply of the jet pump.
  • the present invention also includes a method for producing effluent contained in an underwater geological formation implemented in the device as previously described, characterized in that - A driving fluid is injected into the fluid line from the platform to the jet pump of the pumping module; - Is collected by the production line, the effluent pumped in the formation and returned to the pumping module in the production tube.
  • the jet pump of the pumping module and the jet pumps situated respectively in each of said wells are controlled simultaneously by the driving fluid line.
  • the jet pumps being of the type of tools and instruments pumped, said pumps are lowered and reassembled from the platform in the production duct to the pumping module, then to each of said wells through the referral device.
  • a tool diameter changing device is used.
  • Figure 1 describes one of the modes of activation of subsea crude oil production.
  • Figure 1 shows the marine element 1 as a whole, the sea floor 2, the geological formation 3 impregnated with fluids that one wishes to extract, such as crude oil mixed with natural gas possibly associated with reservoir water.
  • Production takes place through different wells 10, 11, 12, 13 distributed so as to efficiently drain the entire extent of the deposit.
  • the number of wells represented in the example chosen is limited to four, which makes it possible to show the possible equipment differences within the framework of the effluent production process.
  • the wells shown 10, 11, 12, 13 are grouped wells "cluster" in an area with insufficient bottom pressure, all four requiring activation inside the well. These wells are then connected via a production conduit 25 to a treatment installation 30 remote from the site.
  • Each of the wells extends from a low end in a hydrocarbon tank to a high end forming a well head 9 located substantially above the ground 2 of the seabed.
  • the wells 10 and 11 represent such a type of embodiment in which the casing 13 internally comprises a production tube 14, the annular volume between the two tubes serving for 1 injection of the working fluid.
  • the invention could find the same advantages with the use of two tubes inside the casing 15, a first tube 34 serving as production tubing and a second tube 35 for injecting the working fluid into the jet pump.
  • the well heads 9 identical on each well are of the TFL type, comprising a single lyre 16 for implanting and removing pumped tools, in particular allowing the passage of TFL jet pumps whose articulated equipment has well-defined dimensions.
  • the moving heads 16 are connected to an underwater switching module 17 of the pumped tools, also ensuring the grouping of the production of each of the wells.
  • This switch module can be the "Rotatif Diverter Module” developed by the ciosohn's et Chantier de Bretagne. It allows you to direct the circulation of tools to or from each of the TFL wells at will.
  • This module is installed on an adapted underwater base plate 18, comparable to that of the U.M.C. ("Underwater Manifold Center” by Shell and Esso, used on the Cormorant deposit in the North Sea).
  • U.M.C. Underwater Manifold Center
  • Esso Used on the Cormorant deposit in the North Sea.
  • This base plate makes it possible to group and connect the main elements of control, command and transfer of underwater production.
  • This pumping module essentially comprises a jet pump 4 of dimensions and geometric shapes close to those of the downhole jet pumps, but of larger dimensions to allow the production of each of the wells, effluents from the deposit and engine fluids having to be recompressed. enabled the activation of wells equipped with jet pumps.
  • This jet pump is equipped with connection and disconnection devices inside the pumping module comparable to those used in the TFL technique, possibly using attached pumpable tools, allowing it to be brought back through the production line. 25 to the treatment platform 30, then put it back in place at the bottom of the sea by reverse circulation. These movements can be controlled by auxiliary hydraulic or electro-hydraulic control systems, through umbilical connections.
  • the pumping module 19 is equipped with a device for storing and connecting organs of 'tightness on pumped tools, to allow TFL jet pumps in particular to circulate in the collection of diameter larger than that of petroleum tubing, according to a process developed by the company OTIS and become classic in TFL technique.
  • TFL well pumps it is then necessary, by means of the appropriate commands, to first remove the underwater jet pump 4 from the pumping module according to the method indicated above, then trigger the return of the well bottom 20, 21, 22, 23, either by reversing the circulation of the working fluid (which is a conventional operation when production takes place through the annular space), or preferably using tools Appropriate removal TFL.
  • the TFL downhole pumps then flow through the well heads, the routing module, the submarine pumping module and the production line. They are replaced at the bottom of the well using a procedure based on the same principles.
  • the production line 25, the driving fluid line 26 of the other connections can be buried between the base and the platform 11, so as to avoid incidents, due for example to hooking with a fishing net, or any other object. moving to near the bottom of the water.
  • the platform 30 (FIG. 1) comprises a separator 31 fed by the production line 30 which separates the gaseous part from the liquid part of the effluent.
  • a fraction of the liquid part of the effluent (water or raw) is repressurized in the pump 33 to produce the working fluid necessary for the operation of the downhole jet pumps 10, 11, 12, 13 and the submarine pump of the pumping module 4.
  • the non-recycled liquid hydrocarbons as well as the gas are generally sent by separate lines, either to storage means, or to other installations such as treatment installations or another platform.
  • the working fluid is for example pressurized from 200 to 300 bar (20 to 30 MPa) when it is desired to produce at the level of the first jet pump an overpressure of 30 bar (3 MPa) of the effluent: this overpressure corresponds approximately to that required to transfer production over a distance of around 30 km.
  • This working fluid feeds, by a high pressure pipe 26, of diameter which may be less than that of the production pipe (for example 6 "5/8 against 8" 5/8 for the production pipe) the various jet pumps pumping module or downhole module.
  • Valves 27 judiciously placed at the well head and on the base plate 18 ensure operational safety, possibly switching off the pumping of the wells whose production stop is decided.
  • the working fluid can thus operate two functions: during the operation of installing or removing jet pumps or other tools, circulation of this equipment; In normal operation, supply or working fluid according to a distribution controlled by the size of the nozzles fitted to the jet pumps of the various jet pumps, downhole or submarine.
  • each of the pumps 20, 21, 22, 23 can operate at characteristics of flow rates and pressures of working fluid adapted to production specifications.
  • Each of the casings, lyres 16 or hydraulic connections in the well, at the wellhead, or in the vicinity of the wellheads as well as the various lines are equipped with valves and bypass conduits, not shown in the figure for more clarity, and of which the man of the art knows the location perfectly.
  • the operating diagram presented in this example offers the advantage of enabling production to be activated both at the bottom of the well and at the bottom of the sea with a minimum of connecting pipes between the deposit and the platform.
  • the method can also operate with independent activation systems for the well bottom and the underwater station, the working fluid being able to be supplied by multiple pumping lines, one for the underwater station and one for the set of wells or one for each well.
  • the completion of the wells may present other variants. In particular, more conventional double TFL completions, with two tubes in each well, can be adopted without changing the indicated operating possibilities.
