Definitions
- the present invention relates to a process intended to maximize the recovery of fluids from liquid hydrocarbon deposits and to facilitate their exploitation with application, in particular to heavy and / or viscous hydrocarbon deposits, and to hydrocarbon deposits having a point high freezing.
- crude oils are made up of a wide variety of hydrocarbons which can range from methane to heavy parafinics sometimes mixed, in extremely variable amounts with cyclic or aromatic hydrocarbons, even even asphaltene-like solids associated with metalloid atoms, metals or others, with possible association of non-hydrocarbon chemicals.
- the exploitation is done by well, and the recovery of the oil in place is a function more particularly, of the number of wells, their spacings, the speed of withdrawal, and the means used for maintain reservoir pressure or to move fluids in place in the deposit to the withdrawal wells.
- a heating fluid is injected into the deposit and sometimes, correlatively or not, fluids helping the displacement of the crude oil in the deposit.
- the invention therefore aims to eliminate all or part of the disadvantages or hazards mentioned above.
- the process for producing the hydrocarbon deposit in particular with the aim of improving the recovery of the effluent, of facilitating its transportation to the treatment installations, as well as its treatment, consists in recovering the light fractions condensable and / or gaseous effluent, even if they are associated in small quantities, and to reinject them into the well (s) and / or into the deposit.
- this method can also successively comprise, heating of the effluent from the well, separation of the gaseous, liquid and solid phases of the effluent, compression, cooling and possibly dehydration of the gaseous phase, with recovery of the condensates. hydrocarbons and the reinjection of condensates in the well or in the deposit.
- the invention also relates to an installation for implementing the method according to the invention, this installation comprising at least one well making it possible to connect the deposit to the surface installations, at least one installation for heating the effluent, at least one separator of the gaseous, liquid and solid phases of the effluent, at least one cooling compression and possibly dehydration unit of the gaseous phase, with recovery of the hydrocarbon condensates and at least one unit for reinjecting the condensates into the well.
- the single figure is the block diagram of an installation for the exploitation of a hydrocarbon deposit with reinjection of the light fractions of the effluent.
- block 1 represents the deposit from which the effluent is removed using the well. production represented by block 2.
- the effluent emanating from this well is reheated in at least one reheating unit 3 at a temperature favorable to the separation of the liquid and gaseous phases and to the segregation of the oil, water and possibly solid constituents in at minus a separation unit 4.
- the gas phase is then cooled and compressed in one or more stages.
- the gas, during this process is dehydrated to a pinkish point such as its water content residual will not cause difficulties in downstream processing facilities.
- the condensates collected at various points in the unit 5 are recovered and separated from the water associated therewith in a purifier 6 and possibly stored in an additional storage unit 7.
- the residual gas recovered at the outlet of unit 5 is then refrigerated in at least one unit 8 using external refrigeration means, at a temperature making it possible to optimize the recovery of light and cold condensates.
- the light and cold condensates are recovered (block 9) and stored in at least one thermally insulated unit 10.
- the residual gases are
- Injected into well 2 or any other well involved in the production of the deposit directly if their pressure is sufficient, or via at least one additional compression unit 11 if their pressure is insufficient to be reinjected at the optimum depth provided in the well (s), or directly in the deposit 1.
- one or the other or the two units 8 and 11 will not necessarily be installed, all or part of the gases being either sold or used to meet energy or operating or detection fluid, field installations.
- the condensates recovered in the purifier 6 are then injected into well 2 or into any other well participating in the production of the deposit, directly if their pressure is sufficient, or via at least one pump if their pressure is insufficient to be reinjected at the optimum depth provided in the / or wells, or directly in the deposit.
- Cold condensates collected by the units 9 are then injected, mixed or not mixed in whole or in part with the condensates recovered by the purifier 6, after pumping and heating (block 13), to satisfy the pressure conditions provided for the injection of the condensates recovered by the purifier 6.
- the start-up of the first well (s) 2 may possibly be carried out by a load of light hydrocarbons (block 1 4) condensed or not, coming from a source external to the wells.
- the water associated with production, and separated by units 4 and 5 can be eliminated on the surface (block 15), but if this water generates pollution or discomfort in the environment, it will be after skimming of the residual oil (block 16), reinjected into / or the deposits 1, in order to maintain the pressure of the latter within a certain measured.
- This residual water can be combined with adjuvants (block 17) modifying its viscosity or causing a swelling effect of the adjuvant water mixture, to move the hydrocarbons in place in the / or the deposits towards the / or producing wells.
- An advantage of the process according to the invention consists in that by reinjecting into the / or the production wells ⁇ u directly into the / or the deposits of light, liquid and / or gaseous hydrocarbons, jointly or not, originating from the / or wells, with any external contribution to facilitate certain operations such as the start of production of the well (s), an effect is obtained of reducing the weight of the column of fluid in the well (s) as well as a reduction which The viscosity of the effluent can be considerable, this in order to improve the productivity of the well (s) and reduce the difficulties of separation of the phases constituting the natural effluent from the wells.
- the injection into the or the deposits of the excess of light hydrocarbons, gaseous or not, produced by the deposit will contribute to increase the recovery of the hydrocarbons from the deposit by washing the matrix, (reservoir rock), decrease in density, viscosity or plasticity of native hydrocarbons, without generating incompatibility problems such as those which can be created by the addition of fluids foreign to the deposit.
