Definitions

  • This invention is concerned generally with the recovery of liquids from underground reservoirs, such as oil reservoirs below the seabed, and provides a novel method and apparatus for use in a liquid recovery system.
  • the invention has been developed primarily, though not exclusively, in connection with the recovery of residual oil from reservoirs in which naturally available delivery pressure e.g. natural gas in the reservoir chamber, has partly been used-up. or reduced to such a level that assistance is required to "lift" the oil.
  • the residual oil in such reservoirs, as well as oil at low pressure in so far untapped reservoirs, represents a significant natural resource which is worth recovering, and particularly as the more readily recoverable sources of oil become used-up.
  • Hydraulic pumps are subdivided into jet pumps, positive displacement (piston) type pumps, and centrifugal pumps driven by turbines.
  • the purpose of the assistance to the uplifting of the reservoir oil is to reduce the hydrostatic load of the column of oil passing up an oil production pipe, thereby allowing reservoir pressure to be more effective.
  • the present invention seeks to use a combination of gas lift and a pumping action in order to provide enhanced flow rates of oil from a well, and with improved efficiency.
  • references to "underground reservoirs” of course will also include reservoirs below the seabed.
  • a concentric twin pipe arrangement which comprises a central oil production pipe or conduit by which the oil is conveyed to a surface wellhead from the reservoir, and an outer pipe or conduit which lines the borehole.
  • An annular space is therefore defined between the outer surface of the central oil production pipe and the inner surface of the liner.
  • a gas inlet is arranged in the wall of the oil production pipe at a significant depth below the wellhead, and takes the form of a tubular component which forms an integral part of the pipe. Pressure gas is then introduced into the annular space, and enters the oil production pipe via the tubular component, and then rises within the pipe and thereby promotes upward movement of oil from the reservoir up the production pipe to the wellhead.
  • This upward movement of the oil is caused by the upward movement of the gas. which reduces the hydrostatic head within the pipe, and for increases in gas pressure up to a critical level of gas pressure, the greater the pressure of gas supply, the higher will be the flow rate of oil.
  • Hydraulic pumping is also used to "lift" oil from underground reservoirs, and employs a hydraulic pump which is located within the oil production pipe, and again at a significant distance below the wellhead.
  • Any suitable driving liquid pressure medium (which in practice is often water) is used to operate the pump, and this is supplied to the annular space between the liner and the oil production pipe, and from which it passes through the wall of the production pipe to enter the pump and cause it to operate.
  • the operation of the pump causes it to act on the oil in the pipe and pump the oil up from the reservoir to the wellhead.
  • the type of pump typically employed is arranged to receive the driving liquid and to mix the driving liquid with the driven liquid (oil) which then pass upwardly together in mixed form to the wellhead, and therefore these two liquids then have to be separated before further handling or treatment of the oil takes place.
  • the pumping effect achieved by this arrangement is obtained by energy transfer within the pump between the driving liquid (water) and the driven liquid (oil) , which causes the pressure of the driving liquid to decrease with consequent reduction in the intake pressure at the oil inlet to the pump, whereby the oil is pumped-up from the reservoir via the pump and then upwardly in mixed form to the wellhead.
  • the use of a hydraulic pump can achieve enhanced flow rate of oil from the reservoir to the wel lhead .
  • the present invention therefore seeks to provide an improved recovery system for lifting liquid from an underground reservoir to a wellhead, and which employs advantageous aspects of "gas lift” and pumping techniques in a combined form.
  • a recovery apparatus for lifting liquid from an underground reservoir to a wellhead comprising : a twin pipe arrangement to extend from the reservoir to the wellhead, and comprising one pipe arranged within another pipe, and in which: a first of the pipes is arranged to convey the liquid from the reservoir upwardly to the wellhead and a second of the pipes is arranged to convey a gaseous driving pressure medium to operate the apparatus: the first pipe incorporates a gas-operated pump which is arranged to receive a supply of gaseous driving pressure medium from the second pipe to operate the pump and thereby cause the pump to apply an upward pumping action to the liquid: and, the arrangement of the pump is such that the gaseous driving pressure medium used to operate the pump can be caused to exhaust into the first pipe and thereby move upwardly with the liquid in the manner of a gas lift.
  • the invention therefore provides for recovery of liquid from an underground reservoir in a combined manner which utilises the advantage of a novel means of applying a pumping action on the liquid in conjunction with a gas lift effect.
  • a method of recovering, or assisting the recovery of liquid from an underground reservoir of liquid by lifting the liquid from the reservoir to a wellhead via a twin pipe arrangement extending from the reservoir to the wellhead, said arrangement comprising one pipe arranged within another pipe, and in which: a first of the pipes conveys liquid from the reservoir upwardly to the wellhead under reservoir pressure and a second of the pipes conveys a gaseous driving pressure medium: the first pipe incorporates a gas-operated pump which receives a supply of gaseous driving pressure medium from the second pipe via a gas pressure inlet and which operates the pump to apply an upward pumping action to the liquid; and . the pump exhausts the gaseous driving pressure medium into the first pipe, after it has caused the pump to apply the upward pumping action to the liquid, so that the exhausted gas can move upwardly with the liquid in the manner of a "gas lift".
  • the gas-operated pump comprises a jet pump which is arranged to receive the supply of gaseous driving pressure medium and to discharge the gas as a throttled jet into the upwardly moving column of liquid in the first pipe in such a way as to create a pressure differential which reduces the hydrostatic load of the column and thereby allows reservoir pressure to be more effective in driving the liquid from the reservoir and up the first pipe to the wel lhead .
  • the jet pump has an inlet chamber which receives the pumped supply of gas from the second pipe, a tapered nozzle outlet from the chamber, a throat arranged to receive the gas jet produced by the nozzle, a by-pass chamber in communication with the throat and with the first pipe to receive liquid from the first pipe from below the jet pump and on which liquid a pumping action is applied by the gas jet issuing from the nozzle, and a diffuser which receives a combined output of gas and pumped liquid from the throat.
  • the design parameters of the nozzle, by-pass chamber, throat, and diffuser will be determined by suitable testing to provide optimum efficiency in utilisation of the energy of the pumped supply of gas which is transferred to the uplifted liquid i.e. to create a substantial pressure differential, and the exhausted gas i.e. after transfer of pumping energy to the uplifted flow of liquid, will then provide further assistance in uplift of the liquid by operating as a "gas lift" during travel upwardly of the first pipe from the jet pump to the wellhead.
  • said first pipe will be an inner pipe arranged within an outer liner which forms said second pipe, and preferably the inner pipe is located centrally within the outer liner.
  • the gaseous driving pressure medium therefore will be supplied to the annular space defined between the outer surface of the internal pipe and the inner surface of the liner, and any suitable gas inlet will be arranged in the wall of the inner pipe in order to communicate the gas in the annular space with a gas pressure inlet to the pump.
  • this arrangement is not essential to the invention, and a reverse arrangement may be provided, in which the gaseous driving pressure medium is supplied to an inner pipe and the upward pumping of the recovered liquid takes place via the annular space between the inner pipe and the outer liner.
  • the invention is particularly applicable to the recovery of oil from reservoirs below the seabed, and the gaseous driving pressure medium will normally be hydrocarbon gas derived from a surface separator. However, it should be understood that the invention is applicable generally to the lifting of liquids from underground reservoirs .
  • the gaseous pressure supply is therefore admitted through a housing aperture to the nozzle section of the jet pump from which it can issue as a high speed jet which is delivered sequentially to the throat section and then to the diffuser section.
  • the by-passed flow of oil is also conveyed to the throat section and then to the diffuser section, and during movement through these sections, energy is transferred from the high speed gas jet as it slows down during movement along the throat and diffuser sections, which applies a pumping action on the slower moving oil flow.
  • the oil flow takes place in an annular space defined between the jet and the walls of the throat and diffuser sections. This .pumping action increases the production rate from the reservoir, and the commingled driving fluid (gas) and reservoir fluids then flow upwardly to the well head .
  • Figure 1 is a schematic illustration of a recovery system and apparatus for lifting oil from an underground reservoir to which the invention may be applied:
  • Figure 2 is a detailed sectional view of one practical embodiment of dual function gas-operated jet pumping arrangement according to the invention: and.
  • Figure 3 is a sectional view, similar to Figure 2. of a further embodiment of gas-operated jet pumping arrangement according to the invention.
  • FIG. 1 of the drawings shows, by way of example only, a recovery system and apparatus for use in lifting oil from an underground oil reservoir.
  • the oil in the reservoir will be assumed to have insufficient reservoir pressure available in order to provide a required upward oil flow rate from the reservoir to a wellhead (not shown) via a twin pipe arrangement within the bore hole.
  • the system which will now be described is therefore intended to enhance the oil flow rate from the reservoir to the wellhead.
  • This example will be described in relation to the upward lifting of oil from a reservoir, but it should be understood that the invention will be applicable generally to the lifting of liquids from underground reservoirs.
  • the recovery system is designated generally by reference 10 and is intended to lift oil from an underground reservoir 11 to a wellhead (not shown) via a twin pipe arrangement which comprises one pipe arranged within another pipe, and extending upwardly from the reservoir 11 to the wellhead.
  • the twin pipe arrangement comprises an inner oil production pipe 12 which is arranged centrally within an outer pipe 13 which comprises a usual liner of a bore hole.
  • the inner pipe 12 comprises the first pipe of the twin pipe arrangement which serves to convey the oil from the reservoir 11 upwardly to the wellhead under the action of reservoir pressure
  • the outer liner pipe 13 serves to convey a gaseous driving pressure medium to improve the rate of uplift of oil.
  • driving medium being supplied to the annular space defined between the outer surface of the inner pipe 12 and the inner surface of the outer liner pipe 13.
  • the pipe 12 has a gas-operated pump (not shown) which is arranged to receive a supply of gaseous driving pressure medium from the annular space 14. and which is able to operate the pump (not shown) and thereby cause the pump to apply an upward pumping action to the oil.
  • the gas from the space 14 passes to the pump via a suitable gas inlet arranged in the wall of the pipe 12.
  • v/hich in the schematic arrangement shown comprises a tubular component 15 having a circumferential ly spaced set of inlet apertures 16.
  • the tubular component 15 forms a component part of the pipe 12.
  • the pump (not shown) which is arranged within the pipe 12 therefore applies an upward pumping action to the oil by creation of a substantial pressure differential, upon the supply of the gaseous pressure medium to operate the pump, but there is a further arrangement whereby the gaseous driving medium which is used to operate the pump is caused to exhaust into the pipe 12, and thereby to move upwardly with the oil in the manner of a gas lift.
  • the gaseous pressure medium supplied to the system has a dual function, in that it provides the power source to drive a pump which exerts a pumping action on the oil, but when it is vented from the pump it then functions in the manner of a gas lift, as the gas bubbles pass upwardly through the pipe 12 alongside the oil which is moving upwardly under dual acti.pn.
  • the arrangement as shown in the drawing comprises an inner oil production pipe and an outer liner which is pressurised with the gaseous pressure medium.
  • the system could readily be reversed, whereby the gaseous pressure supply is conveyed to an inner pipe, and then moves outwardly to operate the pump which exerts a dual action upward pumping movement to oil which moves upwardly through the annular space defined between the outer liner and the inner pipe.

  • Figure 1 shows, in schematic form only, the manner by which a supply of gaseous pressure medium may be utilised in a dual function (a) to provide input power to a pump and (b) after exhausting from powering the pump to mingle with the upwardly pumped flow of oil to augment the flow by the "gas lift" effect.
  • Figure 2 shows one practical embodiment by which this may be achieved.

  • a supply of gaseous pressure medium preferably comprising hydrocarbon gas at substantial pressure e.g. in the range 2000 to 4000 psi. is conveyed to an inlet chamber 24a of the nozzle section 20 via an aperture 23 in the outer housing 17. and an inlet 24 to the nozzle section 20, and then a high speed gas jet is formed in tapered nozzle outlet 24b which issues into the throat section 21 and then subsequently into the diffuser section 22.
  • a high speed gas jet is formed in tapered nozzle outlet 24b which issues into the throat section 21 and then subsequently into the diffuser section 22.
  • the jet travels along the throat section 21 and diffuser section 22, its velocity decreases.
  • the column of oil moving upwardly under reservoir pressure in production pipe 12 is guided in by-pass manner around the nozzle section 20. as shown by arrow 25. and into an annular by-pass chamber 26 surrounding the outlet of nozzle section 20.
  • the oil (reservoir fluid) is relatively slower moving than the high speed gas jet, and energy is therefore transferred from the gas jet to the slower
  • the passage of the gas jet along the throat 21 and into the diffuser 22 also creates a pressure differential which is applied to the upwardly moving column of oil to assist its upward movement.
  • the passage of the gas jet along throat 21 and diffuser 22 causes a reduction of pressure in the column of oil downstream of the nozzle section 20 relative to the pressure prevailing upstream of the nozzle section i.e. below the nozzle section, which reduces the hydrostatic load of the column extending up the production pipe to the wellhead, and thereby allows the reservoir (driving) pressure to be more effective.
  • Figure 2 is a schematic illustration only, and the design and dimensions of the nozzle section 20, throat 21 and diffuser 22 will be determined experimentally to provide the most advantageous utilisation of the energy of the gaseous pressure supply, to suit any particular oil production facility.
  • the design parameters of the nozzle section 20. chamber 26, throat section 21 and diffuser section 22 will be selected according to tests carried out on the particular gas and liquid media involved, so as to optimise the efficiency of transfer of pumping energy from the gas jet to the liquid, while allowing the exhausted gas to function as a "gas lift" to assist the uplift of liquid e.g. crude oil to the wellhead.
  • Preliminary testing of the concept has been carried out on a land based test facility, in advance of field testing on an existing oil production platform, and has shown favourable indications, using fresh water in place of oil and nitrogen gas in place of hydrocarbon gas.
  • a jet pump design generally similar in principle to that shown schematically in Figure 2 was evaluated, with fresh water being pumped along a pipe incorporating the jet pump at rates between 2000 to 4000 bbl / day using a triplex pump. Nitrogen gas was injected into the jet pump as a power fluid, at rates between 1 to 6 mmscf / day, _and pressures between 2000 to 5000 psi. A variable choke was used to control the pump discharge pressure, allowing the pressure rise generated across the jet pump to be monitored.
  • the jet pump was found to be successful in developing a positive head, which showed that the gas / liquid mixing provided sufficient momentum to overcome the frictional losses through the pump.
  • One indication of trial pump performance comprised a pressure rise from 1800 to 1940 p ⁇ ig when pumping 2000 bbl / day of water with 3 mmscf / day of nitrogen.
  • the nitrogen supply pressure was 4000 psig.
  • This improvement is commercially significant, in that the high pressure driving gas fluid supply is already available to provide a gas lift effect, and the incorporation of the specially designed jet pump into the production pipe will provide this improvement in output rate without need for any appreciable increase in operating costs and extra equipment. It is envisaged that further increase in the rate of output beyond the 5% value already achieved will be obtainable, subject to further refinement in the design parameters of the components of the jet pump.
  • Jet pump 30 will be incorporated as a separate tubular component into an oil production line, in similar manner to that shown in Figure 2. and comprises a nozzle section 31, a throat section 32 and a diffuser section 33. As can be seen from Figure 3. nozzle section 31 defines a convergent passage for incoming high pressure gas. and which is then directed through a nozzle 34 having a circular array of circumferential ly spaced jet outlets 35.
  • the upwardly flowing column of liquid e.g. oil passes into the jet pump 30 by way of inlet 36 and then into annular chamber 37 which surrounds the nozzle section 31, and which comprises a suction chamber.
  • the cylindrical wall 38 of suction chamber 37 then merges into a converging wall 39 which defines a contraction chamber, and wall 39 then merges into a slightly diverging wall defining the mixing throat section 32.
  • Throat section 32 then merges into the diverging wall of diffuser section 33.
  • the design features of the various component sections of jet pump 30. and including particularly the annular array of jet outlets 35, are intended to provide further enhancement in application of pressure differential to the upwardly flowing column of liquid which draws the liquid via inlet 36 into the jet pump 30.
  • the gas jets issuing from nozzle section 31 then form gas bubbles in the diffuser section 33 which give additional "lift” to the upwardly moving column of oil by way of "gas lift” effect.
  • Figure 3 shows generally axially extending jet outlets 35, but it is envisaged that further advantage may be achievable if the jet outlets 35 are at least slightly convergent e.g. to follow the convergence of the wall 39 of the contraction chamber.
  • Figure 3 is a schematic illustration only, and again, as with the previously described schematic illustrations, the design shape and dimensions may be varied,- as found best by experimental testing ⁇ to suit particular requirements of any oil production facility, the type of oil being uplifted and the gaseous pressure driving medium employed, which usually will be hydrocarbon gas.

Abstract

Procédé et appareil de récupération permettant de pomper un liquide se trouvant dans un réservoir souterrain (11) et de le diriger vers une tête de puits par un dispositif de tuyaux jumelés (12, 13) s'étendant depuis le réservoir (11) jusqu'à la tête de puits et comprenant un tuyau (12) placé dans un autre tuyau (13), le premier tuyau (12) acheminant en haut vers la tête de puits le liquide se trouvant dans le réservoir (11), tandis que le deuxième tuyau (13) sert à acheminer un milieu de pression de commande gazeux, par exemple un gaz d'hydrocarbure, qui fait fonctionner ledit système. Le premier tuyau (12) comprend une pompe à jet de conception spéciale (20, 30) conçue pour recevoir l'alimentation en milieu de pression de commande gazeux provenant du deuxième tuyau (13), de manière à créer un différentiel de pression dans la pompe à jet et par là à contribuer à l'élévation du liquide dans le tuyau (12) sous la pression du réservoir, la charge hydrostatique de la colonne de liquide en ascension étant ainsi réduite. Après avoir effectué cette opération de pompage, le gaz est évacué dans la colonne de flux de liquide ascensionnel et s'élève avec elle à la manière d'une extraction au gaz.
