Definitions

  • the cavity is partially filled with liquid to be stored by the annular space between the tubing and the column of tubes and there is disposed above the stored liquid, a cushion of liquefied gas in equilibrium with the vapor phase above it, sent through the annular space between the tubing and the column of tubes.
  • the depth of the cavity, the height of the liquid stored in the cavity, and the height of the cushion of liquefied gas, is selected in such a way that at the moment of withdrawal practically all the liquid is evacuated from the cavity when all of the liquefied gas is vaporized.
  • the present invention relates to a method for the subterranean storage and withdrawal of a liquid, and more particularly of brine or crude petrol, in and from an excavated cavity in a saline geological formation.
  • Subterranean storage and withdrawal methods for such liquids are already known, which consist after storage, of introducing the liquid to be stored into a subterranean cavity excavated in a layer of salt, by the intermediary of a tube connecting the summit of this cavity to the surface, in the interior of which is disposed coaxially a column of withdrawal tubes descending into the cavity to a short distance from the bottom of the latter, then, at the moment of withdrawal, sending to the surface of the stored liquid, by the annular space between the tubing and the column of tubes, a gas under pressure, which forces the liquid to ascend in the column of tubes and to thus evacuate the storage cavity.
  • a liquid such as brine or crude petrol in and from the cavity excavated in a saline for-mation
  • a subterranean storage and withdrawal of a liquid such as brine or crude petrol, in a cavity, excavated in a saline formation, the summit of which cavity is connected to the surface by the intermediary of a tubing, in the interior of which is disposed coaxially a column of withdrawal tubes descending into the cavity to a short distance from the bottom of the latter, according to which method the cavity is filled with the liquid to be stored by the annular space between the tubing and the column of tubes to the surface of the liquid, and the pressure of a compressed fluid is used to evacuate the liquid through the column of tubes, wherein, for storage the cavity is only partially filled with the liquid to be stored and there is disposed above the liquid, a cushion of liquefied gas in equilibrium with the vapour phase surmounting it, sent through the annular space between the tubing and the column of tubes, the depth of the cavity, the height of the liquid stored in this cavity and the height of the cushion of liquefied gas, being selected in such a way
  • the cushion of liquefied gas preferably extends to the summit of the cavity.
  • FIGURE 1 shows in schematic section a storage cavity filled with liquid and liquid carbonic gas
  • FIGURES 2, 3 and 4 are analogous view of FIGURE 1 showing the various stages of withdrawal
  • FIGURE 5 shows the curves of pressure variation of the carbonic gas, as a function of the depth
  • FIGURE 6 shows a graph for the utilisation of the method, drawn for a geothermic gradient of 3 C. per meters.
  • the storage and withdrawal installation used comprises a cavity 1, of which the bottom 2 is at the depth z and the summit 3 at the depth l, and which is connected to the surface by a tubing 4, in the interior of which is disposed, coaxially, a column of tubes 5 descending to a short distance from the bottom 2 of the cavity 1.
  • the cavity 1 is filled with a liquid to be stored 6, to a predetermined heightv k, reckoned starting from the bottom 2 of the cavity 1, by the annular space 7 between the tubing 4 and the column of tubes 5, then is led in by the same annular channel liquefied carbonio gas 8, forming a cushion of height ho above the stored liquids 6.
  • the density of the column of corresponding fluid is between 0.3 and 0.6 and the fluid 9 corresponds then always to a diphasic mixture of liquid and vapour, of which the pressure at each height is the saturated vapour pressure provided by reading the curves 10 of FIGURE 5.
  • carbonic anhydride 48-stored liquids 6 is equal to the pressure above the cushion of liqueded gas (point P of curve 10) increased by the pressure exerted by the height ho of the liquefied gas of density 0.8; this pressure is represented by the point A of FIG- URE 5, and the curve representing the Variation of the pressure in the stored carbonic anhydride as a function of the depth is the curve OPA.
  • the pressure of withdrawal is the difference between the pressure above the stored liquid 6, at the interface of the cushion of liquefied gas -8 and of this liquid 6, and the pressure due to the weight of the height of withdrawn liquid in the column of tubes 5.
  • the use of the brine itself may also be suppressed, by storing the cushion of liquid carbonic anhydride directly above crude petrol.
  • the carbonic gas used for the application of the method is manufactured from separator gas, by combustion and drying, gas which in the countries of high crude petrol production is currently burnt without being used.
