Other existing or future terminal devices or servers that are applicable to this application should also be included within the scope of protection of this application, and are hereby incorporated by reference.
[0077] This application provides a data processing method, which can be applied to the above-mentioned...

This method can be implemented by... Figure 1 The computer device 101 in the middle performs the operation. For example... Figure 2 As shown, the method includes the following steps 201 to 204.
[0078] In step 201, based on the three-dimensional seismic data of the target area and the logging data of the long-term shut-in wells included in the target area, the thermal reservoir parameters of each sub-region of the thermal reservoir in the target area are determined.
[0079] In the exemplary embodiments of this application, the target area is a study area, which includes a living area. A long-term shutdown well refers to a well that has been continuously shut down for more than three months.
[0080] In one possible implementation, the process of determining the reservoir parameters of each sub-region of the target area's geothermal reservoir based on 3D seismic data of the target area and logging data from long-term inactive wells within the target area includes: performing fine structural interpretation of the geothermal reservoir based on the 3D seismic data of the target area and logging data from long-term inactive wells within the target area; establishing structural interpretation surfaces and fault surfaces of the geothermal reservoir; and performing fine stratigraphic correlation and sand body correlation to obtain the reservoir parameters of each sub-region of the target area's geothermal reservoir. The reservoir parameters include sand body thickness, porosity, and permeability. Optionally, the reservoir parameters also include structural features, roof depth, and formation thickness.
[0081] In one possible implementation, some long-term shut-in wells lack temperature measurement data. Therefore, to address the problem of insufficient temperature data in certain areas of the thermal reservoir, the sub-regions with available temperature data use hard temperature data, that is, the temperature of the sub-region with available temperature data is taken as the temperature of that sub-region. For areas without temperature data, the temperature data of the oil and gas-bearing layers is used to back-calculate and establish a low-temperature gradient isosurface. Using the low-temperature gradient isosurface constraint, Kriging interpolation is performed on the hard temperature data to establish a temperature field model of the target area, thereby obtaining the temperature of the sub-regions without temperature data in each sub-region of the thermal reservoir of the target area.
[0082] In step 202, based on the thermal storage parameters of each sub-region, a favorable thermal storage region is determined in each sub-region, and the thermal storage parameters of the favorable thermal storage region meet the corresponding parameter requirements.
[0083] Among them, the parameters of the thermal reservoir include sand body thickness, porosity, permeability and temperature.

[0085] The thickness threshold, porosity threshold, permeability threshold, and temperature threshold are all set based on experience or adjusted according to the implementation environment, and this application embodiment does not limit them. For example, the thickness threshold is 100 meters (m), the porosity threshold is 25%, the permeability threshold is 100 millidarcy (md), and the temperature is 150 degrees Celsius (°C).
[0086] In one possible implementation, the process of determining favorable geothermal reservoir areas in each sub-region based on the geothermal reservoir parameters of each sub-region includes: determining the type of each sub-region based on the geothermal reservoir parameters of each sub-region; and determining the sub-regions in each sub-region whose region type is high porosity, high permeability, thick layer, and high temperature as favorable geothermal reservoir areas.

Sub-regions with porosity greater than or equal to 15% and less than 25%, permeability greater than or equal to 10 millidarcy and less than 100 millidarcy, sand body thickness greater than or equal to 20 meters and less than 100 meters, and temperature greater than or equal to 90 degrees Celsius and less than 150 degrees Celsius are classified as medium-porosity, medium-permeability, medium-layer, medium-temperature. Sub-regions with porosity less than 15%, permeability less than 10 millidarcy, sand body thickness less than 20 meters, and temperature greater than or equal to 20 degrees Celsius and less than 90 degrees Celsius are classified as low-porosity, low-permeability, thin-layer, low-temperature.
[0088] In step 203, the geothermal resource volume of each target well is determined based on the logging data of each target well. Any target well is a long-term shut-in well located in a favorable geothermal reservoir area.
[0089] The logging data for the target well includes the porosity and temperature of various regions of the target well.
[0090] In one possible implementation, the process of determining the geothermal resource quantity of each target well based on the logging data of each target well includes: for any target well among the target wells, determining the comprehensive specific heat capacity of each region of the target well based on the porosity of each region of the target well; determining the thermal reservoir evaluation parameters of each region of the target well based on the comprehensive specific heat capacity and the temperature of each region of the target well, the thermal reservoir evaluation parameters of each region of the target well being used to indicate the geothermal resources of that region of the target well; determining the geothermal resource quantity of each region of the target well based on the thermal reservoir evaluation parameters and the net-to-gross ratio of each region of the target well; and determining the geothermal resource quantity of any target well based on the geothermal resource quantity of each region of the target well.
[0091] The comprehensive specific heat capacity of each region of any target well is determined according to the porosity of each region of any target well using the following formula (1).
[0092]
[0093] In the above formula (1), C i Let J be the comprehensive specific heat capacity of the i-th region of any target well (unit: J / kg comprehensive (joules per kilogram of degree Celsius)).

Let i be the specific heat capacity of the fluid in the i-th region of any target well (unit: J / kg well volume (joules per kilogram of degrees Celsius)), where i is an integer greater than 0.
[0094] Optionally, the logging data for any target well may also include rock density, rock specific heat capacity, fluid density, and fluid specific heat capacity for each region of the target well.
[0095] In one possible implementation, the thermal reservoir evaluation parameters of each region of any target well are determined according to the following formula (2) based on the comprehensive specific heat capacity and temperature of each region of any target well.
[0096] CpT i =C i *(T i -T0) formula (2)

[0098] In one possible implementation, before determining the geothermal resource quantity of each region of any target well based on the thermal reservoir evaluation parameters and the net-to-gross ratio of each region of any target well, it is necessary to first obtain the net-to-gross ratio of each region of any target well. This application embodiment does not limit the process for determining the net-to-gross ratio of each region of any target well. Optionally, for any region within any region of any target well, the net-to-gross ratio of that region is determined based on the effective rock volume of that region and the effective rock volume of the target well. For example, the quotient between the effective rock volume of any region and the effective rock volume of the target well is used as the net-to-gross ratio of that region.
[0099] For example, the net-to-gross ratio of any region of any target well is determined according to the following formula (3) based on the effective rock volume of any region of any target well and the effective rock volume of any target well.
[0100]
[0101] In the above formula (3), NTG i V represents the net-to-gross ratio of the i-th region of any target well. net V represents the effective rock volume of the i-th region of any target well. total The effective rock volume for any target well.

[0105] In another possible implementation, the geothermal resource quantity of each region of any target well can be determined based on the thermal reservoir evaluation parameters of each region of any target well and the effective rock volume of each region of any target well.
[0106] For example, the geothermal resource quantity of each region of any target well is determined according to the following formula (5) based on the thermal reservoir evaluation parameters of each region of any target well and the effective rock volume of each region of any target well.
[0107] Q i =V net *CpT i Formula (5)

Optionally, embodiments of this application provide a table showing the correspondence between various evaluation elements and rating scales, as shown in Table 2 below.

For other evaluation factors, the rating scales are shown in Table 2 above, and will not be repeated here.
[0129] In one possible implementation, the weight parameters corresponding to each evaluation element are set based on experience or adjusted according to the implementation environment; this application embodiment does not limit this. It should be noted that the sum of the weight parameters corresponding to each evaluation element and the weight parameter corresponding to the geothermal resource quantity is 1. Table 3 below is an exemplary table of the weight parameters corresponding to each evaluation element provided in this application embodiment.
[0130] Table 3
[0131]
[0132] As shown in Table 3 above, the weight parameter corresponding to the structural morphology is 0.025, the weight parameter corresponding to the thermal reservoir lithology is 0.025, and the weight parameters corresponding to other evaluation elements are shown in Table 3 above, which will not be repeated here.
[0133] In one possible implementation, the membership degree of any target well is determined according to the following formula (7) based on the rating scale corresponding to the geothermal resource quantity of any target well, the weight number corresponding to the geothermal resource quantity, the rating scale corresponding to the evaluation element of any target well, and the weight parameter corresponding to the evaluation element.
[0134]
[0135] In the above formula (7), p j Let A be the membership degree of the j-th target well. j Let α be the rating scale corresponding to the geothermal resource quantity of the j-th target well, and let α be the weight parameter corresponding to the geothermal resource quantity. Let i be the rating scale corresponding to the i-th evaluation element of the j-th target well. Let m be the weight parameter corresponding to the i-th evaluation element of the j-th target well, and m be the number of evaluation elements.
[0136] In one possible implementation, after determining the membership degree of any target well, the membership degree of any target well is normalized to obtain the index value of any target well. Optionally, the process of normalizing the membership degree of any target well to obtain the index value of any target well includes: determining the average membership degree and the standard deviation of the membership degree based on the membership degree of each target well; and determining the index value of any target well based on the membership degree, the average membership degree, and the standard deviation of the membership degree.
[0137] For example, the index value of any target well is determined according to the following formula (8) based on the membership degree, the average membership degree and the standard deviation of the membership degree of any target well.
[0138]
[0139] In the above formula (8), PCI j Let p be the index value of the j-th target well. j Let μ be the membership degree of the j-th target well, μ be the average membership degree, and σ be the standard deviation of the membership degree.
[0140] Table 4 below is a table of membership degrees and index values for each well provided in an embodiment of this application.
[0141] Table 4
[0142]
[0143] As shown in Table 4 above, the rating scale for well J9 is 0.3 for structural morphology, 0.4 for reservoir lithology, 0.4 for reservoir burial depth, 0.4 for reservoir thickness, 0.4 for reservoir temperature, 0.4 for reservoir properties, 0.4 for reservoir-to-land ratio, 0.4 for geothermal resources, 0.4 for wellbore conditions, 0.4 for surface pipelines, and 0.4 for yield. Well J9 has a membership degree of 0.3975 and an index value of 99.35. The rating scales, membership degrees, and index values for the various evaluation elements of other wells are shown in Table 4 and will not be elaborated upon here.
[0144] In one possible implementation, after determining the index values of each target well, since the index values of each target well are used to indicate whether each target well can be converted into a geothermal well, it is necessary to determine the number of geothermal wells required for the target area, and then determine whether each target well can be converted into a geothermal well.
[0145] Optionally, based on the heating area of the target region, the heating demand per square meter, and the heating capacity of a single well, a target quantity is determined, which is the number of geothermal wells required for the target region. The index values of each target well are then sorted according to the target order to obtain a ranking result. The target wells with the highest target quantity in the ranking result can be converted into geothermal wells. The target order is from largest to smallest.
[0146] The process of determining the target quantity based on the heating area of the target area, the heating demand per square meter, and the heating capacity of a single well includes: determining the total heating demand of the target area based on the heating area of the target area and the heating demand per square meter; and determining the target quantity based on the total heating demand of the target area and the heating capacity of a single well.
[0147] Optionally, the product of the heating area of the target region and the heating demand per square meter is determined as the total heating demand of the target region. The quotient between the total heating demand of the target region and the heating capacity of a single well is determined as the target quantity.
[0148] For example, the total heating demand of the target area is determined according to the following formula (9) based on the heating area of the target area and the heating demand per square meter.
[0149] Q total =S*q formula (9)
[0150] In the above formula (9), Q total Let S be the total heating demand of the target area, S be the heating area of the target area, and q be the heating demand per square meter.
[0151] The target quantity is determined according to the total heating demand of the target area and the heating capacity of a single well, as follows (10).
[0152]
[0153] In the above formula (10), N well For the target quantity, Q total Q represents the total heating demand for the target area. well For the heating supply of a single well.
[0154] In one possible implementation, before determining the target quantity based on the heating area of the target region, the heating demand per square meter, and the heating capacity of a single well, it is necessary to first determine the heating capacity of a single well. This application embodiment does not limit the method for determining the heating capacity of a single well. Optionally, the heating capacity of a single well can be determined based on the specific heat capacity of water, the density of water, the temperature difference of the well water, and the fluid production of the well.
[0155] For example, the heat supply of a single well is determined according to the following formula (11) based on the specific heat capacity of water, the density of water, the temperature difference of well water and the fluid production of the well.
[0156] Q well =c*ρ*Δt*F formula (11)
[0157] In the above formula (11), Q well Let c be the heat supply of a single well, ρ be the specific heat capacity of water, Δt be the temperature difference of the well water, and F be the fluid production rate of the well. The temperature difference of the well water refers to the difference between the outgoing and returning water temperatures. The temperature difference of the well water and the fluid production rate of the well are set based on experience or adjusted according to the implementation environment; this application does not limit these settings.
[0158] For example, if the target area requires 5 geothermal wells, and there are 10 target wells, these 10 target wells are sorted in descending order based on their index values. The resulting sorting is: Target Well 1, Target Well 2, Target Well 3, Target Well 4, Target Well 5, Target Well 6, Target Well 7, Target Well 8, Target Well 9, Target Well 10. The first 5 wells are determined to be convertible into geothermal wells. That is, Target Well 1, Target Well 2, Target Well 3, Target Well 4, and Target Well 5 are determined to be convertible into geothermal wells.
[0159] The method provided in this application has achieved good application results in a certain area. When converted to a long-term geothermal well, the initial maximum daily fluid production reached 463 cubic meters. During the large, medium, and small drop pressure reduction experiments, the wellhead temperature ranged from 48 to 52 degrees Celsius, the maximum allowable production rate was 55.5 cubic meters per hour, corresponding to a dynamic water level of 129.2 meters, and a single-well geothermal fluid production of 1333 cubic meters per day. Therefore, this area was determined to be a geothermal field with a medium production capacity.
[0160] The above method, when determining whether long-term dormant wells within a target area can be converted into geothermal wells, first identifies favorable geothermal reservoir areas within the target area to ensure that the target area possesses the conditions for resource development. Then, it determines the geothermal resource volume of long-term dormant wells located within these favorable reservoir areas. Based on the geothermal resource volume of each target well within these favorable reservoir areas, it determines the index value for each target well. This index value is used to determine whether the corresponding target well can be converted into a geothermal well. This method allows for a comprehensive, thorough, and accurate determination of the index values of long-term dormant wells, enabling the screening of those that can be converted into geothermal wells. This makes the evaluation of the geothermal resource potential of long-term dormant wells more refined and improves the reliability of geothermal development and utilization. Moreover, since the conversion involves long-term dormant wells into geothermal wells, there is no need to acquire new geothermal wells, thus saving costs.
