Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0051] like Figure 1 As shown, a method for reconstructing the structural-thermal history of a marine carbonate formation according to an embodiment of the present invention includes:

[0052] Step S1, reconstructing the tectonic-thermal history of the first marine carbonate formation using a low-temperature thermochronological paleotemperature scale;

[0053] Step S2, reconstructing the tectonic-thermal history of the second marine carbonate formation using cluster isotope paleothermometer;

[0054] Step S3: Coupledly reconstructing the tectonic-thermal history of the marine carbonate rock formation based on the tectonic-thermal history of the first marine carbonate rock formation and the tectonic-thermal history of the second marine carbonate rock formation.

[0055] In the embodiment of the present invention, taking a certain basin as an example, outcrop samples in a marine carbonate formation are collected.

[0056] In step S1, the reconstruction of the tectonic-thermal history of the first marine carbonate formation using the low-temperature thermochronology paleothermometer includes:

[0057] Step A1: performing paleothermal parameter testing on clastic rock outcrop samples in marine carbonate formations, wherein the paleothermal parameters include organic vitrinite reflectance, apatite fission track and (U-Th) / He age, and zircon fission track and (U-Th) / He age;

[0058] Specifically, the collected clastic rock outcrop samples were tested to obtain organic vitrinite reflectance, apatite fission track and (U-Th) / He age, and zircon fission track and (U-Th) / He age;

[0059] Step A2: reconstructing the tectonic-thermal history of the first marine carbonate formation based on the paleothermal parameters of low-temperature thermochronology, the present geothermal field, and the characteristic parameters of the burial history of the formation;

[0060] Specifically, through comparative analysis and mutual verification of paleothermal parameters such as organic vitrinite reflectance, apatite fission track and (U-Th) / He age, zircon fission track and (U-Th) / He age, combined with the current geothermal field and burial history characteristics of the stratum, the tectonic-thermal history of the stratum, namely the tectonic-thermal history of the first marine carbonate stratum, was reconstructed using Hefty software, such as Figure 2 shown.

[0061] Through comparative analysis and mutual verification of these paleothermal parameters, combined with the current geothermal field and burial history characteristics of the strata, the tectonic-thermal history of the strata was reconstructed using Hefty software.

[0062] In step S2, reconstructing the tectonic-thermal history of the second marine carbonate formation using the cluster isotope paleothermometer includes:

[0063] Step B1, measured isotope temperature of carbonate rock clusters T(Δ 47 )

[0064] Step B2: Based on the measured temperature T(Δ 47 ), determine the isotope composition of carbonate clusters 13 C- 18 O bond solid-state rearrangement relationship;

[0065] Step B3: Cluster isotope-based 13 C- 18 O bond solid-state rearrangement relationship, determine the closing temperature and equilibrium temperature of solid-state rearrangement;

[0066] Step B4: Based on the initial diagenetic temperature of the sample, the closure temperature and equilibrium temperature of the solid-state rearrangement, and the measured temperature of carbonate cluster isotopes, the tectonic-thermal history of the second marine carbonate formation is obtained.

[0067] In step B1, the carbonate rock cluster isotope measured temperature T (Δ 47 ), including:

[0068] Step C1: Based on the phosphoric acid dissolution experiment of carbonate rock samples, the mineral 13 C- 18 O bond information, specifically, through petrographic observation, cathodoluminescence and XRD analysis, carbonate rock samples (mainly microcrystals) with weak cathodoluminescence and calcite content >95% were selected, and the carbonate rock minerals were dissolved using phosphoric acid to release CO2, and the isotope of the released CO2 was determined to obtain the mineral 13 C- 18 O key information;

[0069] Step C2, mineral-based 13 C-18 O bond information, calculate the CO2 abundance Δ at 47 parts per thousand 47 , and the CO2 abundance of 47 mass parts per thousand represents the abundance of carbonate minerals. 13 C- 18 The abundance of O bonds is calculated as follows:

[0070]

[0071] In formula (1), R 47 = 47 CO2 / 44 CO2 abundance ratio; R 46 = 46 CO2 / 44 CO2 abundance ratio; R 45 = 45 CO2 / 44 CO2 abundance ratio; R 18 = 18 O / 16 Abundance ratio of O; R 17 = 17 O / 16 Abundance ratio of O; R 13 = 13 C / 12 The abundance ratio of C, where 47 CO2, 46 CO2, 45 CO2, 44 CO2, 18 O. 17 O. 16 O. 13 C and 12 The C content can be obtained from the mineral 13 C- 18 O key information is obtained.

[0072] Step C3: According to Δ 47 The relationship between the cluster isotope measured temperature T(Δ 47 ), specifically, according to the previous empirical formula, the Δ 47 The calculation formula of (‰)-T(K) is shown in formula (2):

[0073]

[0074] The Δ calculated according to formula (1) 47 Enter into formula (2) to obtain the cluster isotope measured temperature T(Δ 47 ), the isotope measured temperature of carbonate rock clusters in this basin is T(Δ 47)The calculation results are shown in Table 1.

[0075] Table 1

[0076]

[0077]

[0078] In step B2-B3, the isotopic temperature T(Δ 47 ), determine the isotope composition of carbonate clusters 13 C- 18 O bond solid state rearrangement relationship, specifically, according to T(Δ 47 ) temperature, the cluster isotope temperature T(Δ 47 ) and the formation temperature, as shown in the figure Figure 3 As shown, from Figure 3 It can be seen that the isotopes of naturally evolved carbonate clusters 13 C- 18 The "closing temperature" of O bond solid-state rearrangement is not higher than 120°C, and the thermodynamic "equilibrium temperature" is not lower than 160°C.

[0079] In step B4, the tectonic-thermal history of the second marine carbonate formation is obtained based on the initial diagenetic temperature of the sample, the closure temperature and equilibrium temperature of the solid-state rearrangement, and the measured temperature of the carbonate cluster isotopes, including:

[0080] Step D1, determining a cluster isotope solid-state rearrangement model based on adjustment of activation energy and frequency factor in a first-order approximate reaction model;

[0081] Specifically, step D1 includes:

[0082] Simulating the cluster isotope temperature using a first-order approximate reaction model to obtain a simulated cluster isotope temperature, wherein the first-order approximate reaction model is a well-known technique in the art and will not be described in detail herein;

[0083] The activation energy and frequency factor in the first-order approximate reaction model are adjusted, and the simulated cluster isotope temperature value obtained after adjustment and the calculated cluster isotope measured temperature T(Δ 47 )Compare;

[0084] Repeat the adjustment and comparison steps until the simulated cluster isotope temperature approaches the calculated cluster isotope temperature. The time-temperature (tT) path at this time is determined as the cluster isotope solid-state rearrangement model.

[0085] Step D2: Based on the initial diagenetic temperature, the closure temperature and equilibrium temperature of the solid-state rearrangement, the solid-state rearrangement model, and the measured isotopic temperature of the carbonate cluster, the tectonic-thermal history of the second marine carbonate formation is obtained;

[0086] The initial diagenetic temperature is determined according to the burial history and diagenetic history characteristics of the stratum; the first-order approximate reaction model used to simulate the cluster isotope temperature value is well known in the art and will not be described in detail here.

[0087] Step D2 sets the initial diagenetic temperature as the starting temperature condition for simulating the tectonic-thermal history, and the closure temperature and equilibrium temperature of the solid-state rearrangement and the measured temperature of the carbonate cluster isotopes as the simulation temperature conditions. The tectonic-thermal history of the second marine carbonate formation is forward-modeled using the solid-state rearrangement model, as shown in FIG. Figure 4 As shown;

[0088] For example, the process of step D2 is listed as follows:

[0089] The initial diagenetic temperature of carbonate rocks in the basin is set to 20℃. The thermal history of the assumed carbonate rock sample is divided into a series of temperature-time intervals with 1Ma as the unit. The activation energy and frequency factor in the reaction are changed. The cluster isotope temperature is simulated using the first-order approximate reaction model. The simulation results are compared with the experimentally measured T(Δ 47 ) values ​​to determine which solid-state rearrangement model is more suitable for simulating carbonate rock samples in sedimentary basins;

[0090] The solid-state rearrangement model determined by the above steps, the closure temperature and equilibrium temperature of the solid-state rearrangement, and the measured temperature of carbonate rock cluster isotopes are performing the most suitable time-temperature (tT) path ( Figure 4 ), the T(Δ 47 )value( Figure 4 The middle dotted line) remained basically unchanged in the Paleozoic, began to rise rapidly in the Jurassic, reached its highest point in the Late Cretaceous, and then began to decline, with the final calculated result being 188°C.

[0091] In step S3, the structural-thermal history of the marine carbonate rock formation is coupled and reconstructed based on the structural-thermal history of the first marine carbonate rock formation and the structural-thermal history of the second marine carbonate rock formation;

[0092] Will Figure 2 Middle curve and Figure 4By comparing the curves in , it can be seen that, in the embodiment of the present invention, the results of reconstructing the tectonic-thermal history of the second marine carbonate rock formation using the cluster isotope paleothermometer are consistent with the results of reconstructing the tectonic-thermal history of the first marine carbonate rock formation using the low-temperature thermochronology paleothermometer, indicating that the modeling of the two paleothermometers is correct and can be coupled to reconstruct the tectonic-thermal history of the formation. When the tectonic-thermal histories reconstructed by the two paleothermometers are inconsistent, the parameters in the solid-state rearrangement model are readjusted. When the trends revealed by the modeling results are consistent, the tectonic-thermal history of the first marine carbonate rock formation and the tectonic-thermal history of the second marine carbonate rock formation can be coupled to reconstruct the tectonic-thermal history of the formation, thereby obtaining a complete and detailed tectonic-thermal history of the marine carbonate rock formation.

[0093] Specifically, based on Figure 2 and Figure 4 The coupled reconstruction of the tectonic-thermal history of the basin reveals three phases: During the Sinian to Early Paleozoic, the basin experienced intracratonic depression, without large-scale magmatic eruptions, and was a tectonic-thermally stable region with low and weakly varying heat flow. During the Permian, heat flow began to increase, reaching a peak in the Middle to Late Permian, indicating tectonic activity. This peak in heat flow was primarily due to the combined effects of crustal extension and thinning and the thermal effects of the Emeishan mantle plume. After the Late Triassic, heat flow gradually declined as magmatic activity and deep thermal processes stabilized.

[0097] The reconstruction module 3 is used to reveal the tectonic-thermal history of the marine carbonate rock formation based on the tectonic-thermal history of the first marine carbonate rock formation and the tectonic-thermal history of the second marine carbonate rock formation.
