[0028] In order to make the personnel in the technical field better understand the present application, the technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, but not all the embodiments.

It should be understood that the data thus used can be interchanged under appropriate circumstances, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein. The case of "target", "original" and the like is similar, which will not be described here.

[0030] Before introducing the embodiments of the present application, the current scheme adopted for temperature field simulation and the reason why it cannot be standardized to implement temperature field simulation will be described exemplarily, so as to better understand the reason why the scheme proposed by the embodiments of the present application can implement standardized temperature field simulation.

[0031] At present, the scheme for simulating the temperature field only includes a temperature field simulation scheme depending on geothermal well logging, geological survey or empirical formula calculation, but the above schemes lack a standardized system simulation process, which will lead to poor reproducibility of the simulated temperature field. At present, there is no standardized temperature field simulation process, so the temperature field simulation cannot be standardized at present.

[0032] In view of this, the embodiment of the present application provides a set of standardized temperature field simulation process by obtaining the geological data and determining the rock thermal physical parameters corresponding to at least one stratum, so as to realize the standardized temperature field simulation. Next, this will be described in detail.

[0033] Figure 1 is a flowchart of a temperature field simulation method provided in the embodiment of the present application. The embodiment is applicable to the case of temperature field simulation. The method can be executed by a temperature field simulation device provided by the embodiment of the present application, and the device can be realized by software and / or hardware. The device can be integrated on an electronic device, and the electronic device can be various user terminals or servers.

[0034] Referring to Figure 1 , the method of the embodiment of the present application specifically includes the following steps:

[0035] S110, obtaining geological data of a target area, and determining a typical profile of the target area according to the geological data.

[0036] The target area can be understood as an area whose temperature field is to be simulated; the target area can be a study area.

[0037] The geological data can be understood as geological data of the target area; the geological data can include at least one of measured geological profile raw data, stratum division and correlation data, petrology and lithofacies data, structural feature data, and a typical profile.

[0038] The typical profile can be understood as a representative profile of the stratum of the target area; referring to Figure 2 , the typical profile can include at least one of a fault, a secondary fault, a stratum boundary, a metamorphic basement, and at least one of Quaternary, Neogene, Paleogene, Cretaceous, Jurassic, Triassic, Permian-Carboniferous sedimentary rock, Ordovician and Cambrian carbonate rock, and Proterozoic and Archean basement.

[0039] In the embodiment of the present application, the geological data can be obtained, and the typical profile can be determined according to the geological data, for example, the typical profile can be selected from the geological data.

[0040] S120, establishing a geological model of the target region according to the typical profile, and determining at least one stratum in the geological model corresponding to a rock thermal physical parameter respectively.

[0041] The geological model can be understood as a model corresponding to the geology of the target region; the geological model can be a two-dimensional or three-dimensional geological model; the geological model may, for example, include Quaternary, Neogene, Paleogene, Cretaceous, Jurassic, Triassic, Permian-Carboniferous sedimentary rock, Ordovician and Cambrian carbonate rock, and Proterozoic and Archean basement.

[0042] The rock thermal physical parameter can be understood as a quantitative parameter describing the physical properties exhibited by the rock in the process of heat transfer, storage and conversion, which can be used to study the thermal behavior of the rock.

[0043] In the embodiments of the present application, the rock thermal physical parameter corresponding to at least one stratum in the geological model can be determined, for example, the lithology of the rock corresponding to each stratum can be analyzed to obtain the rock thermal physical parameter corresponding to the stratum.

[0044] Optionally, the rock thermal physical parameter includes at least one of rock thermal conductivity, rock heat generation rate and rock specific heat capacity.

[0045] The rock thermal conductivity can be understood as the thermal conductivity of the rock in the corresponding stratum.

[0046] The rock heat generation rate corresponds to the heat generation rate of the rock in the corresponding stratum.

[0047] The rock specific heat capacity corresponds to the specific heat capacity of the rock in the corresponding stratum.

[0048] In the embodiments of the present application, it is considered that at least one of the rock thermal conductivity, the rock heat generation rate and the rock specific heat capacity will affect the temperature field distribution, so that the rock thermal physical parameter can include at least one of the rock thermal conductivity, the rock heat generation rate and the rock specific heat capacity, thereby improving the simulation accuracy of the temperature field simulation.

[0049] S130, simulating the temperature field of the target region according to the geological model and the rock thermal physical parameter corresponding to at least one stratum respectively.

[0050] The temperature field can be understood as a physical quantity field describing the temperature distribution of the target region.

[0051] In the embodiments of the present application, the temperature field of the target region can be simulated according to the geological model and the rock thermal physical parameter corresponding to at least one stratum respectively, to obtain a temperature field simulation result. The temperature field simulation result can be understood as a result obtained by simulating the temperature field of the target region, and the temperature field simulation result can include a temperature field in the form of temperature contour distribution and / or a well temperature curve with depth change of a well located in the target region.

[0052] Compared with related schemes which are insufficient in spatial resolution, adaptability and simulation capability, the scheme of the embodiment of the present application can improve the spatial resolution, adaptability (applicable to temperature field simulation under different conditions) and simulation capability of the temperature field simulation, and has high engineering value, and can provide reliable theoretical basis for rational development and utilization of geothermal resources.

[0053] The scheme of the embodiment of the present application can be applied to geothermal resource distribution prediction, regional heat flow background cause analysis and geothermal energy development and utilization research and other fields.

[0054] The technical scheme of the embodiment of the present application obtains geological data of a target region, and determines a typical profile of the target region according to the geological data, to provide a geological basis for establishment of a site model through the typical profile; establishes a geological model of the target region according to the typical profile, and determines rock thermal physical property parameters corresponding to at least one stratum in the geological model, to provide a temperature basis for simulation of a temperature field through the rock thermal physical property parameters corresponding to the at least one stratum; and simulates the temperature field of the target region according to the geological model and the rock thermal physical property parameters corresponding to the at least one stratum, to realize simulation of the temperature field. The above technical scheme simulates the temperature field through the obtained geological data and the determined rock thermal physical property parameters corresponding to the at least one stratum, provides a standardized temperature field simulation process, and thus realizes standardized simulation of the temperature field.

[0055] An optional technical scheme, after simulating the temperature field of the target region according to the geological model and the rock thermal physical property parameters corresponding to the at least one stratum, the temperature field simulation method further includes: determining regional tectonic features of the target region; and establishing a geothermal genesis mode diagram of the target region according to the regional tectonic features and the obtained temperature field simulation result.

[0056] The regional tectonic features can be understood as features of regional tectonics (characterizing crustal deformation and tectonic movement traces) of the target region.

[0057] In the embodiment of the present application, the regional tectonic features can be determined, for example, the regional tectonic features can be determined according to the geological data.

[0058] The geothermal genesis mode diagram can be understood as a schematic diagram graphically summarizing at least one of a geothermal resource formation mechanism, a key control factor and an energy transfer process of the target region.

[0059] In the embodiment of the present application, the geothermal genesis pattern diagram is established by the regional tectonic characteristics and the temperature field simulation results. For example, the geothermal genesis pattern diagram can be established by the regional tectonic characteristics and the first temperature field simulation result and the second temperature field simulation result obtained from the temperature field simulation results.

[0060] In the embodiment of the present application, the geothermal resource aggregation genesis can be revealed by determining the geothermal genesis pattern diagram representing the geothermal resource aggregation genesis. For example, the geothermal genesis pattern diagram of the Yimeng uplift region (target region) can reveal that the high heat flow background genesis (geothermal resource aggregation genesis) of the Yimeng uplift region can be summarized as a composite pattern of deep basement heat generation, fault conduction and overlying low thermal conductivity layer heat aggregation. The determination of the geothermal genesis pattern diagram has high effectiveness and scientificity.

[0061] In another optional technical solution, the temperature field of the target region is simulated according to the geologic model and the rock thermal physical parameters of at least one stratum, and the simulation includes: performing adaptive grid division on the geologic model; and simulating the temperature field of the target region by multi-physical field simulation according to the rock thermal physical parameters of at least one stratum and the obtained grid division result.

[0062] The grid division result can be understood as a result of adaptive grid division on the geologic model.

[0063] In the embodiment of the present application, the adaptive grid division can be performed on the geologic model.

[0064] The multi-physical field simulation can be understood as a technical system for simulating the interaction and evolution process of a physical field (for example, a temperature field) in time and space by a numerical calculation method.

[0065] In the embodiment of the present application, the temperature field can be simulated by multi-physical field simulation according to the rock thermal physical parameters of at least one stratum and the grid division result. For example, the temperature field can be simulated by multi-physical field simulation (COMSOL Multiphysics) according to the rock thermal physical parameters of at least one stratum and the grid division result. For example, the rock thermal physical parameters of at least one stratum and the grid division result can be taken as inputs of the multi-physical field simulation to calculate and simulate the steady-state temperature field by a multi-physical field simulation solver, so as to obtain the temperature field simulation result.

[0066] In the embodiment of the present application, the temperature field of the target region is simulated by multi-physical field simulation according to the rock thermal physical parameters of at least one stratum and the obtained grid division result, which can improve the comprehensiveness and accuracy of the temperature field simulation.

[0067] In another optional technical solution, before simulating the temperature field of the target region according to the geological model and the rock thermal physical parameters corresponding to the at least one stratum, the method further comprises: performing boundary processing on the geological model, wherein the boundary processing comprises at least one of applying a heat flux boundary to the bottom of the geological model, applying a constant temperature boundary to the upper part of the geological model, and applying a thermal insulation boundary to the side of the geological model; and updating the geological model according to the obtained boundary processing result.

[0068] The boundary processing can be understood as processing the boundary of the geological model.

[0069] In the embodiments of the present application, the boundary processing can be performed on the geological model, which can be directly applying the corresponding boundary to the geological model, or can be explicitly specifying the relevant attributes (at least one of the heat flux, temperature, and thermal insulation or the like) of the boundary of the geological model.

[0070] The heat flux boundary can be understood as a boundary that explicitly specifies the heat flow (mechanisms such as conduction, convection, and radiation of heat flow).

[0071] The constant temperature boundary can be understood as a boundary that explicitly specifies the temperature; for example, the temperature of the constant temperature boundary can be 15 degrees Celsius (℃).

[0072] The thermal insulation boundary can be understood as a boundary that explicitly specifies that the geological model has no heat exchange with the external environment.

[0073] The boundary processing result can be understood as the result obtained after the boundary processing is performed on the geological model.

[0074] In the embodiments of the present application, the boundary processing can be performed on the geological model, which can be directly applying the corresponding boundary to the geological model, or can be explicitly specifying the relevant attributes (at least one of the heat flux, temperature, and thermal insulation or the like) of the boundary of the geological model.

[0075] Figure 3 is a flowchart of another temperature field simulation method provided in the embodiments of the present application. The present embodiment is optimized on the basis of the above-mentioned various technical solutions. In the present embodiment, before simulating the temperature field of the target region according to the geological model and the rock thermal physical parameters corresponding to the at least one stratum, the temperature field simulation method further comprises: for each stratum in the at least one stratum, according to the stratum conditions of the stratum, correcting the rock thermal physical parameters of the stratum, wherein the stratum conditions comprise at least one of the dry condition, the saturated condition, and the true temperature condition of the stratum; and updating the rock thermal physical parameters of the stratum according to the obtained correction result. Wherein, the explanations of the same or corresponding terms as in the above-mentioned various embodiments are not repeated here.

[0076] See Figure 3 The method in this embodiment may specifically include the following steps:

[0077] S210. Obtain geological data of the target area and determine the typical profile of the target area based on the geological data.

[0078] S220. Based on typical profiles, establish a geological model of the target area and determine the rock thermal properties parameters corresponding to at least one stratum in the geological model.

[0079] S230. For each of at least one strata, the rock thermal properties of the strata are corrected according to the strata conditions, wherein the strata conditions include at least one of the following: dry conditions, water saturation conditions, and true temperature conditions.

[0080] Among them, stratigraphic conditions can be understood as the attribute conditions of the stratigraphy.

[0081] Dry conditions can be understood as conditions that characterize whether a formation is dry.

[0082] Water saturation conditions can be understood as conditions that characterize whether a formation is saturated with water.

[0083] The true temperature condition can be understood as the condition that characterizes the actual temperature of the strata.

[0084] In this embodiment of the invention, the thermal properties of the rock can be corrected based on at least one of the formation's dryness conditions, water saturation conditions, and actual temperature conditions.

[0085] In this embodiment of the invention, when the rock thermal properties include multiple parameters, one or more of the multiple parameters can be modified. For example, based on the formation conditions, only the thermal conductivity of the rock thermal properties of the formation can be modified.

[0086] S240. Based on the obtained correction results, update the rock thermal properties parameters of the formation.

[0087] The correction result can be understood as the result obtained by correcting the thermal properties of the rocks in the formation.

[0088] In this embodiment of the invention, the rock thermal properties of the formation can be updated based on the correction results. For example, the correction results can be used as the rock thermal properties of the formation.

[0089] S250. Based on the geological model and the rock thermal properties parameters corresponding to at least one stratum, simulate the temperature field of the target area.

[0090] The technical scheme of the embodiment of the present application is that, for each of the at least one formation, the rock thermal physical property parameters of the formation are corrected according to the formation condition of the formation, wherein the formation condition includes at least one of a dry condition, a water-saturated condition and a true temperature condition of the formation; and the rock thermal physical property parameters of the formation are updated according to the obtained correction result. Compared with the related scheme in which the change of the rock thermal physical property parameters with the formation condition is not considered, the above technical scheme can correct the rock thermal physical property parameters according to the formation condition of the formation, so that the rock thermal physical property parameters can be corrected according to the change of the formation condition, thereby reducing the deviation of the temperature field simulation, improving the fitting degree of the temperature field simulation and the actual situation, and thus improving the simulation accuracy of the temperature field simulation.

[0091] An optional technical scheme is that, before the rock thermal physical property parameters of the formation are corrected according to the formation condition of the formation, the temperature field simulation method further includes: taking the rock thermal physical property parameters as uncorrected parameters; and simulating the temperature field of the target region according to the geological model and the rock thermal physical property parameters corresponding to the at least one formation respectively, including: simulating the temperature field of the target region according to the geological model and the rock thermal physical property parameters corresponding to the at least one formation respectively and the uncorrected parameters.

[0092] The uncorrected parameters can be understood as the rock thermal physical property parameters when the rock thermal physical property parameters of the formation are not corrected.

[0093] In the embodiment of the present application, the rock thermal physical property parameters when the rock thermal physical property parameters of the formation are corrected can be taken as the uncorrected parameters.

[0094] In the embodiment of the present application, the temperature field can be simulated according to the geological model and the rock thermal physical property parameters corresponding to the at least one formation respectively and the uncorrected parameters. For example, referring to Figure 4 (b) part (here, the temperature field simulation result includes a temperature field in the form of temperature contour line distribution) in FIG. 1, a first temperature field can be simulated according to the geological model and the uncorrected parameters corresponding to the at least one formation respectively to obtain a first temperature field simulation result (without considering the correction of the rock thermal physical property parameters); and referring to Figure 4 (a) part (here, the temperature field simulation result includes a temperature field in the form of temperature contour line distribution) in FIG. 1, a second temperature field can be simulated according to the geological model and the rock thermal physical property parameters corresponding to the at least one formation respectively to obtain a second temperature field simulation result (considering the correction of the rock thermal physical property parameters); and the simulated first temperature field simulation result and the second temperature field simulation result can be taken as the final required temperature field simulation result, for example, referring to Figure 5(Here, the temperature field simulation result includes a well temperature-depth curve as an example of temperature field simulation result), the temperature field simulation result can include a first well temperature-depth curve in the first temperature field simulation result (a well temperature-depth curve without considering rock thermal physical property parameter correction, indicated as not considering in Figure 5 , and a second well temperature-depth curve in the second temperature field simulation result (a well temperature-depth curve considering rock thermal physical property parameter correction, indicated as considering in Figure 5 ).

[0095] It should be noted that after the first temperature field simulation result and the second temperature field simulation result are simulated, the first temperature field simulation result and the second temperature field simulation result can be compared and analyzed to determine the formation condition influence data on the temperature field according to the obtained analysis result. For example, the scheme of the embodiment of the present application is carried out for the Yimeng uplift region (target region) of a certain area, the influence data of the Yimeng uplift region is obtained, and it can be known from the Yimeng uplift region that the well temperature-depth curve has high fitting degree with the measured value in the case of considering rock thermal physical property parameter correction, and the high temperature zone is mainly distributed in the fracture development and low rock thermal conductivity rock covering area.

[0096] In the embodiment of the present application, the temperature field of the target region is simulated according to the geological model and the rock thermal physical property parameters and uncorrected parameters of at least one formation, which can improve the comprehensiveness and accuracy of temperature field simulation.

[0097] In order to better understand the technical scheme of the above-mentioned embodiment of the present application, an optional example is provided. Illustratively, geological data is obtained, and a typical profile is determined according to the geological data, wherein the typical profile at least includes fractures and each basement (which can be a deep basement located in the deep part of the formation of the target region); a geological model is established according to the typical profile, and the rock thermal physical property parameters of at least one formation in the geological model are determined; for each formation in the at least one formation, the rock thermal physical property parameters of the formation are corrected according to the formation condition of the formation; the rock thermal physical property parameters of the formation are updated according to the correction result; the temperature field of the target region is simulated according to the geological model and the rock thermal physical property parameters of at least one formation, considering the deep basement heat generation effect and the fracture conduction effect; the regional structural features are determined; and the geothermal genesis model diagram is established according to the regional structural features and the obtained temperature field simulation result. The above-mentioned basic scheme can integrate the rock thermal physical property correction, the deep basement heat generation effect and the fracture conduction effect into the temperature field simulation, which can not only improve the accuracy of temperature field simulation, but also significantly improve the interpretation ability of geothermal genesis.
