Definitions
- SU 605429 describes a process for the development of gas condensate deposits.
- the deposit is flooded with highly mineralized water.
- the high mineralization prevents the solution of gases in the flood water and thus allows the displacement of the natural gas and the natural gas condensate from the area of the borehole near the production well.
- a disadvantage of this method is the massive dilution of the deposit by the injected flood water.
- the injected flood water itself can lead to a blockage of the Bohrlochnahzone. This method does not allow for an effective increase in production rates.
- SU 1596081 and RU 2064572 disclose methods of treating the gas condensate reservoir with seismic waves. The seismic waves should thereby lead to an increase in the delivery rate from the gas condensate deposit. This process is not very efficient, especially in low-lying deposits.
- the gas mixture with retrograde condensation behavior at point (A) is gaseous and single-phase.
- the gas mixture at point (B) reaches the dew point curve (dpc).
- the gas mixture is virtually 100% gaseous, but an infinitesimal amount of liquid begins to form.
- the gas mixture passes into the two-phase region (l + v), in which a liquid phase is formed by partial condensation in addition to the gas phase.
- natural gas and liquid natural gas condensate are juxtaposed in a two-phase system.
- the gas mixture again reaches the dew point curve (dpc) (marked by dot (D) in FIG. 1).
- the dew point curve (dpc) is exceeded, the gas mixture reverts to the single-phase gaseous state.
- point (E) in Figure 1 the gas mixture is again in gaseous and single-phase.
- the illustration in FIG. 1 merely serves to explain the condensation behavior of retrograde gas mixtures without restricting the present invention.
- T L is higher than the crystallization temperature T K of the solution
- T L must allow complete hydrolysis of the urea and complete oxidation of the at least one metal in a relatively short time, for example within 1 to 20 days.
- a gas mixture with a retrograde condensation behavior has the following composition (data in mol%):
- the method of the invention it is possible to exclusively feed natural gas through the production well.
- the state of aggregation of the further substances optionally present in the natural gas or in the natural gas condensate likewise depends on the pressure and the temperature in the deposit or in the production well.
- the other substances may likewise be present in liquid form or in gaseous form in the mixture conveyed through the production well.
- the reservoir pressure is sufficient to deliver natural gas and / or natural gas condensate from the reservoir through the production well, this is done by conventional production methods.
- the subject matter of the present invention is thus also a method in which, after the sinking, the at least one production well is introduced into the underground gas condensate deposit (process step a) and before the fluid composition (FZ) is injected into the underground gas condensate reservoir (process step b). ) first natural gas and / or natural gas condensate (by conventional methods) through the at least one production well is promoted.
- this is not mandatory.
- the reduction of the delivery rate is due to the formation of the critical area (KB), which is at least partially blocked by liquid natural gas condensate.
- the flowable composition (FZ) contains in addition to the at least one metal urea and water.
- the flowable composition (FZ) contains 5 to 70 wt .-% urea, 1 to 30 wt .-% of at least one metal, preferably aluminum, and 20 to 80 wt .-% water, each based on the total weight of the flowable composition (FZ).
- the present invention thus also provides a process in which the flowable composition (FZ) contains from 5 to 70% by weight of urea,
- the flowable composition (FZ) preferably contains from 20 to 40% by weight of urea
- the flowable composition (FZ) is usually provided above ground by dissolving the urea in water.
- further additives for example surface-active components (surfactants).
- the urea is usually used as granules or industrially produced aqueous urea solution is used, for example, 32.5% aqueous urea solution "Ad Blue ®" BASF SE.
- the dissolution behavior of urea in water is shown in the phase diagram in FIG.
- the urea content of the flowable composition (FZ) in% by weight, based on the total weight of the flowable composition (FZ); in the event that the flowable composition (FZ) contains only urea and water.
- the temperature is given in ° C.
- the proportion of remaining after the hydrolysis of the urea residual water (RW) is given, based on the total weight of the flowable composition used (FZ).
- KH indicates therein the urea fraction of the flowable composition (FZ) used in% by weight, based on the total weight of the flowable composition (FZ) used.
- the rate at which the hydrolysis of the urea and the oxidation of the at least one metal occurs depends on the reservoir temperature T L of the underground gas condensate reservoir and the temperature at which the fluid composition (FZ) is injected in process step b). At high
- the period of rest is generally in the range of 1 to 10 days.
- the rest phase may be shorter, for example 1 to 5 days.
- the rest phase may be shorter, for example 1 to 5 days.
- the reservoir pressure is about 5 650 atm (658.6 bar).
- the permeability of the deposit is low and is between 0.2 and 1, 0 ⁇ 2 .
- the porosity of the gas condensate deposit ranges from 0.2 to 0.25%.
