Definitions
- a method of simulating the geological formation of a fluvial zone is provided.
- the invention relates to the field of simulation of geological processes for the study of the subsoil. We are particularly interested in the formation phenomena of fluvial zones.
- the sands are areas of interest for oil exploration. We therefore seek to predict their presence and their characteristics.
- a method for simulating the geological formation of a fluvial zone comprising:
- the term stochastic may include the superposition of a meandering term and a random disturbance. In doing so, channel modeling is made more realistic.
- meandering can include a superposition of at least one trigonometric function. Such a representation is realistic for a meandering term, and easily parameterizable.
- the observation data may comprise at least one of the following types of data:
- the probability of the occurrence of a separation of a particle into two independent particles can be estimated and, in case of occurrence, proceed to such separation;
- the probability of the occurrence of a disappearance of a particle can be estimated based on the observation data.
- a channeling belt defining a width and a thickness in which the particles are allowed to move.
- a computer program product for geological formation simulation of a fluvial zone intended to be stored in a memory of a central unit, and / or stored on a memory medium intended to cooperate with a reader of said central unit and / or downloaded via a telecommunication network, characterized in that it comprises instructions for implementing such a method when it is executed on a programmable machine.
- FIG. 1 is a diagrammatic view of a channel
- FIG. 2a is a schematic view from above of a channel model
- FIG. 2b is a diagrammatic sectional view of the channel
- FIG. 3 is an illustrative diagram of the zoning in a channel
- FIG. 4 is an overall diagram illustrating particle trajectory modeling in a channel part
- FIG. 5 is an illustrative diagram similar to that of FIG. 3 describing a separation process
- FIG. 6 is a view similar to FIG. 3 describing a melting process
- FIG. 7 is a view similar to FIG. 3 describing a disappearing process
- Figure 8 is a schematic top view of a model in which is symbolized a displacement field imposed by an external source.
- FIG. 1 schematically depicts a fluvial zone 1 extending between an upstream zone 2a and a downstream zone 2b.
- the fluvial zone to be modeled is considered over a certain width 1, a certain thickness e and a certain length L. Thickness and width are for example variable along this length.
- a river zone 1 generally comprises a channel
- This channel was formed by the flow of particles over time from the upstream zone to the downstream zone.
- a channel may have at least one of the following configurations; here being listed here in the order in which they are generally found between the upstream zone and the downstream zone:
- a meandering system 4c in which the channels have a high sinuosity
- a deltaic system 4e in which a main channel splits into a number of secondary channels opening into the sea, and
- turbid system 4f related to the interaction with another flow, such as a maritime flow.
- a spatial model of the fluvial zone can be realized in the form of a surface or volume mesh in which each of the elements represents a location of the fluvial zone.
- observation data can for example include:
- a gradient of flow velocity in the fluvial zone which can for example be defined on the basis of a hydraulic gradient in this zone, and / or from the altitude data of the upstream and downstream regions,
- geometric parameters of the fluvial zone such as, for example, the current geometry of the surface of the zone, the discontinuities observed, etc.
- geological data resulting from imagery for example seismic imagery carried out in the zone
- FIG. 2a thus represents from above a spatial model of a region of the fluvial zone, presenting a set of mesh elements, for example parallelepipedal (squares in plan view), in which a channel model 5 has already been generated by simulation.
- FIG. 2b represents a sectional view along the line B-B of FIG. 2a, thus showing a slice of the calculated channel model 5.
- this channel has three of the distinct zones mentioned above in relation to FIG. 1, which are identified in FIG. 3 by references 6a, 6b and 6c.
- Each of these zones can be the subject of a separate modeling, while respecting the constraints of connectivity at the interface between two zones. The modeling of one of these zones will be described hereinafter with reference to FIG.
- this is zone 6a.
- the channel 8 defines a width in which the particles are allowed to flow, this width possibly being variable along the average flow curve (the width is here represented constant).
- the channeling belt may extend not only on the surface, but also to a certain depth below the representation plane of the window 7a.
- the area shown comprises an upstream hydraulic load 10a and a downstream hydraulic load 10b.
- the displacement of particles in the spatial model is simulated by superimposing a deterministic term and a stochastic term. For example, we write:
- ⁇ represents the displacement of the particle
- AD represents the deterministic term
- ⁇ represents the stochastic term.
- the deterministic term is defined from the flow field shown on window 7a of FIG.
- the term stochastic is added to this term to define a perturbation of the deterministic term.
- the stochastic term can itself be realized as the superposition of two terms.
- the first of these terms is a meandering term that can easily be realized, from the mathematical point of view, by one or more trigonometric terms (sinusoidal) as represented on the window 7b of FIG. 4.
- the curve 11 a period and a half of a sine extending between points a and g, and of a given amplitude.
- the points a and g correspond to the upstream and downstream zones of the modeled zone, and the number of periods as well as the amplitude of the sinus can be parameterized independently for this zone.
- the meandriform term is superimposed on a random perturbation represented on the window 7b by the arrows 12.
- This random term is defined as a disturbance of the sinusoidal curve 11.
- the orientation and / or the amplitude of the perturbation can be determined randomly on a plurality of points 13 of the sinusoidal curve 11, for example equidistant from each other, or of equidistant abscissa, as shown.
- the window 7c represents a simulated trajectory 13 of particles, within the channeling belt 8, obtained from a superposition of the type mentioned above.
- the parameterization (period, amplitude) of the sinusoidal function is determined according to the zone modeled for the fluvial zone.
- the parameterization (frequency, intensity) of the random disturbance can be determined according to the zone considered. This parameterization can also be performed taking into account other observation data, among the observation data mentioned above.
- Such divisions are visible at 15 in Figure 5.
- the probability of having a division may depend on the area. In the example of FIG. 5, it is possible, for example, to provide that no division is possible in zone 6a. In zone 6b, it can be foreseen that divisions are possible, and that, in the case of division, a particle divides into a maximum number of daughter particles (here the maximum number of daughter particles is two). Furthermore, it is also possible to set the maximum number of divisions allowed for a particle in a given zone (at most two divisions in zone 6b shown in FIG. 5 in the example shown).
- FIG. 6 Another phenomenon that can be modeled is shown in FIG. 6. If two particles are located at a location at one and the same time, it is a matter of junction or fusion of these particles. Such a merger is visible in FIG. 6 as represented by the references 16. It will be noted that the merger process can be implemented in parallel with the division process represented above, with divisions occurring on the example of Figure 6, in point 15.
- the possibility of implementing a merger phenomenon is probabilized. This probability may for example depend on the area considered. For example, it can be expected that one proceeds systematically to a merger in the zone 6a. In zone 6b, as shown, it is possible to never implement fusion.
- FIG. 7 Another phenomenon that can be modeled is shown in FIG. 7. It is, in this case, a phenomenon of disappearance of a particle. For example, it is possible to predict that a particle will disappear after having traveled a certain distance, or to probabilize the possibility of seeing a disappearance as a function of the path traveled by the particle. Such disappearances are visible, referenced by reference 17 in FIG. 7. Separation, junction and disappearance can be probabilized according to observation data.
- Another phenomenon that can be modeled is the superposition of another energy source to the flow. in the river zone.
- this other energy source is a littoral drift as represented by the arrow 18 in FIG. 8.
- This term may for example be added to the deterministic term directly determined by the hydraulic gradient in the area when calculating the particle displacement.
- the displacement of particles in the fluvial zone is simulated according to one and / or the other of the equations and phenomena presented below.
- This simulation is for example implemented on a programmable machine, such as a computer, having stored in memory a computer program stored in memory locally or accessible via a network, and programmed to implement the above steps. It is possible to implement an end-of-simulation determination criterion, for example based on the number of simulated particles, on the simulation time, and / or on the similarity of certain results of the simulation with observation data.
- the simulation can evaluate one or both of the following parameters:
- the realistic modeling of channel formation, obtained above, and the above parameters may be useful in the context of the oil production of certain channel locations. For example, one can predict, on a channel sometimes several hundred kilometers long, areas likely to contain hydrocarbon deposits. If an area is predicted to be of particular interest for such an operation, provision may be made to place an operating facility and, where appropriate, to produce hydrocarbons from the results of the simulation process.
