Definitions
- the present invention relates to the field of measuring the diffusion coefficient of water in a porous medium, in particular a cement paste, a concrete or a compact rock resulting from an underground formation.
- Diffusion properties in porous media are an important parameter in some applications. For example, when one wants to store liquids or gases in geological layers, the cover above the storage area must act as a barrier against the transport of gas or liquids stored. In the context of nuclear waste, cementitious materials surrounding the waste must also act as a barrier and have diffusion properties as low as possible. In general, the diffusion properties in porous media are long to measure. A well known method used for many years is the technique of diffusion through (of the English "Through diffusion"). Such a method is described in particular in the document CD. Shackelford, Journal of Contaminant Hydrology 7 (1991) 177-217.
- the porous material to be tested is cut in the form of a disc; one of the (upstream) faces of the disk is brought into contact with the diffusing liquid (for example water) in which a tracer (for example tritiated water) has been inserted; the other face (downstream) is also brought into contact with the liquid but in the absence of tracer.
- the diffusing liquid for example water
- a tracer for example tritiated water
- NMR Nuclear Magnetic Resonance
- the position of molecules can be spatially coded in a manner similar to NMR imaging and deduced from diffusion coefficients in a wide variety of situations.
- the NMR technique is possible, however, only if the magnetization generated in the sample has a sufficiently long life, that is to say with quite long relaxation times.
- the time required for the coding of the magnetization is of the order of 10 ms, and thus the relaxation times must be of the same order of magnitude. This is not the case in cementitious media or compact geological environments (cover rock) for which the relaxation times are close to 1 ms or less. These weak relaxation times do not therefore allow the measurement of diffusion coefficients by the conventional NMR technique.
- the NMR technique is faster when the sample is small. This is also true for the conventional technique for which the thickness of the sample is an important parameter.
- the sample size can not be reduced below certain values; for example for a concrete containing aggregates of a size of a few millimeters (up to one centimeter), the dimensions of the samples must be kept sufficiently large relative to the size of these heterogeneities.
- the measurement of the diffusion coefficient requires a significant time because of the need to have a large sample size.
- the present invention relates to a method for measuring the diffusion coefficient of water in a porous medium, for which the coefficient is measured by an NMR technique, and for which the sample has a shape of a hollow cylinder.
- This specific form of the sample makes it possible to measure the diffusion coefficient by an NMR technique more rapidly for any type of material including concretes which comprise large aggregates.
- the invention relates to a method for measuring the diffusion coefficient of water in a porous medium.
- the method comprises the following steps:
- a sample of said porous medium is prepared in the form of a hollow cylinder; b) saturating said sample of said porous medium with water;
- said porous medium is a cement paste, a concrete, or a rock.
- said concrete contains aggregates of a size of a few millimeters.
- the outer diameter of said hollow cylinder is between 20 and 80 mm, and the inner diameter of said hollow cylinder is between 2 and 25 mm.
- said tracer fluid and not detected by NMR nuclear magnetic resonance method is a deuterium.
- said hollow cylinder is formed by double coring of said porous medium.
- the invention relates to a method for storing a fluid in an underground formation, in which the following steps are carried out: a) determining the diffusion coefficient of the water in at least one rock above said subterranean formation by means of the diffusion coefficient measurement method according to one of the preceding characteristics; and
- said fluid to be stored is an acid gas, especially C0 2 .
- the invention relates to a method for storing a radioactive material in an enclosure, in which the following steps are carried out:
- said enclosure is constructed with the cement paste having the lowest diffusion coefficient
- Figure 1 illustrates NMR measuring means.
- FIG. 2 is a comparative curve of measurement times and volumes for a solid cylinder and for three hollow cylinders as a function of the ratio between inside diameter and outside diameter of the hollow cylinder.
- FIG. 3 is a curve of the measurement of the diffusion coefficient for a cement paste using the method according to the invention.
- FIG. 4 is a curve of the measurement of the diffusion coefficient for a limestone rock using the method according to the invention.
- FIG. 5 is a curve of the measurement of the diffusion coefficient for a limestone rock by means of a method according to the prior art.
- the present invention relates to a method for measuring the diffusion coefficient of water in a porous medium.
- coefficient of diffusion of the water within a porous medium is a characteristic of a porous medium that depends, with respect to the diffusion properties of the water outside the porous medium, on the first order of the porosity, then the structure of the porous medium (tortuosity).
- the porous medium in question may be a cement paste, a concrete, a rock, or any similar medium.
- the porous medium may be a concrete which comprises aggregates (for example crushed rocks) of a size of a few millimeters.
- the method for measuring the diffusion coefficient of water in a porous medium comprises the following steps:
- a sample of the porous medium is prepared in the form of a hollow cylinder, for example by double coring;
- the concentration of water present in the sample of the porous medium is measured by a nuclear magnetic resonance (NMR) method
- the hollow cylinder shape of the sample makes it possible to reduce the measurement time, while keeping sufficient dimensions of the sample, in particular for materials comprising aggregates, in order to allow measurements of the diffusion coefficient by an NMR technique. Thus, it is possible to reduce the measurement time of the diffusion coefficient of water within the porous coefficient, and those for all materials.
- the NMR method has the advantage of being four to ten times faster than the standard method (diffusion method through) for the same sample size.
- the shape of the hollow cylinder is taken into account by means of a shape factor which depends in particular on the internal and external diameters of the sample.
- the measurement of the diffusion coefficient is adapted to the specific form of the sample.
- the dimensions of the hollow cylinder satisfy the following conditions: the outer diameter of the hollow cylinder is between 20 and 80 mm, these dimensions ensure a sample of sufficient size especially for concretes comprising aggregates;
- the inside diameter of the hollow cylinder is between 2 and 25 mm, these dimensions allow a gain in the measurement time while maintaining a sufficient sample volume for the measurement.
- the length of the hollow cylinder may be between 10 and 100 mm.
- the inside diameter of the hollow cylinder may be between 2 and 50% of the outer diameter of the hollow cylinder, in order to allow a gain in the measurement time while maintaining a sufficient volume of sample for the measurement.
- the inside diameter of the hollow cylinder may be between 15 and 30% of the outside diameter to optimize the gain of the measurement time while maintaining a sufficient volume of sample for the measurement.
- NMR devices made from permanent magnets with magnetic fields close to 0.5 T are perfectly suitable. These are indeed of lower cost. These devices generally comprise permanent magnets, a solenoid acting as transmitting and receiving antenna, and suitable electronics for generating NMR pulse sequences.
- the radio frequency field can be set to detect protons (and not deuterons) according to Larmor's law. The presence of specific coils for generating pulsed field gradients is not necessary.
- An apparatus geometry adapted to the size of the analyzed sample can be chosen to optimize the antenna fill factor and thus the signal-to-noise ratio.
- FIG. 1 schematically illustrates, in a nonlimiting manner, an NMR measuring apparatus that can be used for the method according to the invention.
- the sample saturated with water 1 is placed within a first magnetic field B 0 (substantially vertical curved arrows) formed by two magnets 2, and a second magnetic field B 1 (straight arrows). dotted) formed by a solenoid 5.
- the NMR measuring apparatus further comprises control means 3 which may comprise means for generating NMR pulse sequences, temperature control means, an amplifier, the control magnets and solenoid, and electronic means.
- the NMR measuring apparatus may include computer means 4 for automating and recording the measurements made.
- the principle of measurement by NMR with the use of a deuterium tracer can be as follows: a sample of the porous medium initially saturated with water is placed in a tube, for example a tube in glass, adapted to the NMR device used. Then, this sample is immersed in deuterium (this time defines the zero time of the experiment). As a reminder, deuterium is heavy water, in the form of an isotope of water.
- the principle of this implementation of the invention is to have two miscible liquids, one of which is not detected in NMR, or more exactly is not detected in NMR because the NMR measuring apparatus is set on the first fluid, water (note: deuterium can be detected by an NMR method, but this detection requires an NMR device set for deuterium and not for water).
- the diffusion of the two species then begins: the deuterium enters the sample, the water leaves it.
- an NMR relaxation measurement technique it is possible to measure the amount of water inside the sample, without being affected by the water outside which has a very long relaxation time. Deuterium is not detected at any time because the device is set to detect water protons.
- the deuterium tracer NMR measurement described here is similar to a so-called in-diffusion measurement, using the terminology of the radionuclide literature.
- the tube may not be permanently placed in the NMR apparatus if the kinetics are slow. Indeed, the sealed glass tube can be stored in an oven at the same temperature as that of the NMR apparatus (for example substantially 30 ° C).
- the NMR measurement method applied for the process according to the invention may be that described in the document P. Bern, P. Bachaud, M. Fleury, Oil & Gas Science and Technology - Review of the Institut für du Pperile 65 (2009). ) 473 ⁇ 184, by implementing a sample in the form of a hollow cylinder.
- the data measured by the meter is the magnetization generated by the proton population within the sample as a function of time M (t).
- the relative concentration C * of water inside the sample can be determined from the measurements of the magnetization by means of an equation of the form:
- the present invention relates to a method of storing a fluid in an underground formation. For this process it is possible to implement the following steps:
- the fluid is stored within the storage zone of the subterranean formation if the diffusion coefficient of the water in the overlying layer is below a predetermined non-dispersion threshold (in other words avoiding leakage) of the fluid to be stored to the overlying layer of the storage area of the subterranean formation.
- This method makes it possible to ensure that the cover rock present above the underground formation acts well as a barrier against the transport of the stored gas or liquids, which makes it possible to avoid leakage of gas or liquid during or after storage.
- a sample of the rock from a layer above the underground formation can be taken, and a hollow cylinder of this rock sample is formed.
- the fluid to be stored in the subterranean formation is a gas, in particular an acid gas, for example CO 2 .
- the present invention relates to a method of storing a radioactive material (for example radioactive waste) in an enclosure made from a cement paste.
- a radioactive material for example radioactive waste
- the following steps can be implemented:
- This method makes it possible to ensure that the cementitious materials surrounding the radioactive materials act as a barrier and have diffusion properties as low as possible, which makes it possible to provide for a storage of radioactive materials avoiding radioactive leaks.
- step a it is possible to form a sample having a hollow cylinder shape of each cement paste to be tested.
- the storage enclosure can be buried in an underground formation.
- FIG. 2 illustrates this comparison for the measurement time T and the investigated volume V, taking as reference the measurement time and the investigated volume for the full cylinder.
- the measurement time T (indicated in a standardized manner with respect to the measuring time for a sample having the shape of a solid cylinder) decreases rapidly according to the inside diameter a of the hollow cylinder
- the volume V (indicated in a standardized way with respect to the volume investigated for a sample in the form of a solid cylinder) investigated decreases little according to the ratio R between the inside diameter and the outside diameter of the hollow cylinder.
- the measurement time decreases by a factor of two for an internal diameter of between 15 and 28% of the outside diameter while the volume investigated decreased by only 5%.
- the duration of the measurement for a full cylinder is of the order of one year. With the geometry of the hollow cylinder having an internal diameter of between 15 and 28% of the outer diameter according to the invention, the duration of the measurement is thus reduced to 6 months or less.
- this example shows that the method according to the invention makes it possible to reduce the measurement time of the diffusion coefficient of water in a porous medium, while maintaining dimensions adapted to measurements for all types of materials.
- the second example concerns the measurement of a diffusion coefficient of water in a cement paste.
- Figure 3 illustrates the relative C concentration of water in the sample having a hollow (normalized) cylinder shape as a function of time t for this sample. Black dots indicate measurements.
- the process according to the invention makes it possible to extract the diffusion coefficient.
- the measurement of the diffusion coefficient on a full cylinder of the same outside diameter lasts more than 700 hours .
- this example also shows that the method according to the invention makes it possible to reduce the measurement time of the diffusion coefficient of water in a porous medium.
- the third example concerns the measurement of the diffusion coefficient of water in a limestone rock of Tavel.
- a hollow cylinder according to the invention was prepared by coring (outer diameter 25.18 mm, internal diameter 13.14, and length 26.73 mm), and on the other hand an inner cylinder (not hollow according to the invention). prior art) from this same coring was used as a reference (diameter 10.83mm length 18.60mm).
- the volume of the first hollow sample is 5.7 times greater than the volume of the second non-hollow sample.
- FIG. 4 illustrates the relative C concentration of water in the sample having a (normalized) hollow cylinder shape as a function of time t for this first sample. Black dots indicate measurements. It can be seen that the process according to the invention makes it possible to extract the diffusion coefficient.
- FIG. 5 illustrates the relative concentration C of water in the sample having a solid (normalized) cylinder shape as a function of time t for this second sample. Black dots indicate measurements.
- the water concentration (normalized between 1 and 0) measured in the two porous samples can be adjusted with the models with a very small error, of the order of 1% except for the very low times for which the error reaches 4%.
- the stabilization time is about 10h, compared to 16h for the full cylinder. It can be deduced that the experiment for the hollow cylinder is faster although the total volume of the sample is 5.7 times larger.
