Description

Technical Field

[0001] The present invention relates to the technical field of geothermal resource development. More specifically, the present invention relates to a method for arranging a geothermal production and injection well group based on data analysis. Background Art

[0002] Geothermal resources are a kind of clean and renewable energy, which are widely distributed inside the earth. With the continuous growth of energy demand and the transformation of the energy structure, the development and utilization of geothermal resources have been paid more and more attention. As an important facility for geothermal resource development, the reasonable arrangement of geothermal production and injection well groups is of great significance for improving the exploitation efficiency of geothermal resources and reducing the exploitation cost. With the continuous progress of data analysis technology, the development and utilization level of geothermal resources has been continuously improved, and the geothermal exploitation effect under different arrangement schemes can be predicted, providing a scientific basis for optimizing the arrangement scheme.

[0003] The existing method for arranging a geothermal production and injection well group based on data analysis mainly includes a geothermal data collection step, a geothermal data analysis step, and a reasonable discrimination step for well position arrangement; the geothermal data collection step mainly collects geological information and geothermal resource-related data through existing tools; the geothermal data analysis step makes data analysis more convenient by converting non-digital parameters into digital geothermal analysis parameters; the reasonable discrimination step for well position arrangement accurately discriminates the existing data through the reasonableness of other well position arrangements to evaluate the reasonableness of the current well position arrangement.

[0004] However, when it is actually used, there are still some disadvantages. For example, in the data collection step, geological information and geothermal resource-related data are collected. However, due to the complex and changeable external environmental factors, the environmental parameters such as temperature, humidity, and heat change unpredictably, and it is difficult for traditional arrangement methods to obtain the changes of these parameters in real time and accurately; the arrangement of geothermal production and injection well groups is often determined by multiple factors, such as heat distribution factors, pumping and drainage activity factors, and economic benefit consideration factors, and it is difficult for traditional monitoring methods to comprehensively analyze and evaluate these factors.

[0029] Preferably, classify the first well location key text through the first well location keyword group and obtain the first well location evaluation value corresponding to the first well location key text. The first well location evaluation value is the target knowledge field involved in the first well location key text, that is, through the knowledge field to which the first well location key text belongs, so as to confirm the knowledge field involved in the first well location evaluation value corresponding to the first well location key text, which helps to improve the rationality of well location evaluation and can select a suitable intelligent well location layout analysis model for subsequent processing according to the first well location key text.

[0041] Figure 2 It is a schematic diagram of the structure of an electronic device of the present invention. Detailed Embodiments

[0042] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0043] As shown in the Figure 1 flowchart of the method for arranging a geothermal extraction and injection well group based on data analysis, the flowchart mainly includes the following steps: S1 to S7.

[0044] S1: Establish a planar coordinate system with an interval of five meters in the target area, locate the wellheads of production wells and injection wells at each coordinate point and at an interval of five meters from it, and store them in the system operation database.

[0045] In this embodiment, it should be specifically noted that the target area is the area where the well group to be arranged is located. A planar coordinate system with an interval of five meters is established in the target area to form a grid with an interval of five meters. The intersection points of the grid are coordinate points. The wellheads of production wells and injection wells at each coordinate point and at an interval of five meters from it are located. The well positions are accurately measured using GPS. At this time, the well positions to be determined are located at the coordinate points, their coordinates are recorded in the planar coordinate system, and they are stored in the system operation database.

[0046] S2: Based on the arrangement of the geothermal extraction and injection well group, select the key text for the first well position; obtain the key text for the second well position, where the key text for the second well position is the key text after the selection of the key text for the first well position.

[0047] In this embodiment, it should be specifically noted that the selection process of the key text for the first well position is as follows:

[0048] A1: Conduct geological modeling on the target distance between the production well and the injection well, and collect geological exploration data, including geological structure, lithology distribution, and thermal reservoir characteristics;

[0049] A2: Use a geographic information system and geological modeling software to construct a three-dimensional geological model, accurately represent the key geological structures of the thermal reservoir, aquitard, and fault in the model, and set the rock physical parameters to reflect the flow characteristics of geothermal fluids;

[0050] A3: Based on the three-dimensional geological model, establish a numerical model of geothermal fluid flow through numerical simulation technology;

[0051] A4: Set different target distance schemes in the numerical model, simulate the extraction and injection processes of the production well and the injection well, and evaluate the mutual influence between the production well and the injection well at different target distances;

[0052] A5: Simulate and verify the influence range of production wells and recharge wells, and estimate the economic benefits of production wells and recharge wells, including investment costs, operation and maintenance costs, and net present value;

[0053] A6: Based on the simulation and verification results, optimize the target distance between production wells and recharge wells, and obtain the first key text of well positions by screening feature words;

[0054] The second key text of well positions is the key text after the selection of the first key text of well positions. Obtain the second key text of well positions, and the obtaining method is as follows:

[0055] B1: Use geophysical exploration methods such as seismic exploration to artificially generate seismic waves and receive their reflected signals, and detect the structural characteristics of underground rock formations, including the shape, strike, scale of faults, and their relative position relationships with the simulated production wells and recharge wells;

[0056] B2: Judge the fault sealing property according to the fault shape, strike, and scale;

[0057] B3: According to the relative position relationships between faults and the simulated production wells and recharge wells, judge whether the pumping ports and drainage ports are on the same fault, and evaluate the exploitation efficiency of geothermal resources, including the production, temperature, and stability of geothermal resources;

[0058] B4: Based on the judgment results, optimize the positions of pumping ports and drainage ports, production wells and recharge wells, and obtain the second key text of well positions by screening feature words.

[0059] In this embodiment, it should be specifically noted that the judgment results include the judgment of fault sealing property and the judgment of the positions of pumping ports and drainage ports. If the fault has good sealing property and can block the oil layer and cut off the connectivity of the oil layer, there is no need to plug such faults. If the fault has a high opening degree, resulting in the channeling between oil layers and the injection water channeling, such faults need to be plugged; if they are on the same fault, the positions of pumping ports and drainage ports need to be adjusted to ensure the safety and efficiency of the layout of production and recharge well groups.

[0060] S3: Conduct primary processing on the selected first key text of well positions. The primary processing operation is used to obtain the first key word group of the first key text of well positions; conduct primary processing on the obtained second key text of well positions. The primary processing operation is used to obtain the second key word group corresponding to the second key text of well positions.

[0061] In this embodiment, it should be specifically noted that the first well position key text and the second well position key text collected are initially processed. Statistical methods are used to identify and process outliers. System operation database query statements are used to remove duplicate data. Through the integration of the associations between the fields of hydrogeological feature analysis, economic benefit analysis, geological exploration analysis, and the relative position analysis of the wellhead and the collected well position key text, a complete analysis data set is formed to ensure the accuracy and consistency of the data.

[0062] S4: Obtain the intelligent analysis model for well position arrangement. According to the intelligent analysis model for well position arrangement and through the first well position keyword group, obtain the first well position evaluation value corresponding to the first well position key text.

[0063] In this embodiment, it should be specifically noted that the intelligent analysis model for well position arrangement is a pre-constructed learning model. By importing the first well position keyword group into the intelligent analysis model for well position arrangement, the intelligent analysis model for well position arrangement obtains the first well position evaluation value according to the first well position keyword group, and sends the first well position evaluation value to the user terminal and stores it in the system operation database;

[0064] The intelligent analysis model for well position arrangement specifically includes: classifying the first well position key text according to the first well position keyword group to obtain the analysis key points corresponding to the first well position key text. The analysis key points corresponding to the first well position key text are the target knowledge fields corresponding to the first well position key text, and the target knowledge fields include the fields of hydrogeological feature analysis, economic benefit analysis, geological exploration analysis, and the relative position analysis of the wellhead; in the preset analysis database, obtain the intelligent analysis model for well position arrangement corresponding to the analysis key points. The preset analysis database is used to store the corresponding relationship between the analysis key points and the intelligent analysis model for well position arrangement.

[0065] Classify the first well location key text through the first well location keyword group, and obtain the first well location evaluation value corresponding to the first well location key text. The first well location evaluation value is the target knowledge field involved in the first well location key text, that is, the knowledge field to which the first well location key text belongs. Thus, confirming the knowledge field involved in the first well location evaluation value corresponding to the first well location key text helps to improve the rationality of well location evaluation and enables the selection of a suitable well location layout intelligent analysis model for subsequent processing according to the first well location key text. The target knowledge fields include, but are not limited to: hydrological feature analysis field, economic benefit analysis field, geological exploration analysis field, and wellhead relative position analysis field. After determining the first well location evaluation value of the first well location key text, obtain a suitable analysis model in the preset analysis database through the correspondence between the well location evaluation value and the well location layout intelligent analysis model in the preset analysis database. The preset analysis database is a database constructed to store multiple well location layout intelligent analysis models, multiple well location evaluation values, and the correspondence between multiple well location layout intelligent analysis models and multiple well location evaluation values. The well location layout intelligent analysis models and the well location evaluation values are in one-to-one correspondence, including, but not limited to: hydrological feature analysis model, economic benefit analysis model, geological exploration analysis model, and wellhead relative position analysis model.

[0066] In this embodiment, it should be specifically noted that before obtaining the well location layout intelligent analysis model and obtaining the first well location evaluation value corresponding to the first well location key text through the first well location keyword group according to the well location layout intelligent analysis model, constructing the well location layout intelligent analysis model specifically includes: obtaining the analysis data set corresponding to the target knowledge field; obtaining the target knowledge graph corresponding to the target knowledge field according to the analysis data set; constructing the well location layout intelligent analysis model according to the target knowledge graph; obtaining analysis data sets of multiple different knowledge fields, including, but not limited to, hydrological feature analysis data set, economic benefit analysis data set, geological exploration analysis data set, and wellhead relative position analysis data set.

[0067] S5: Based on the first well location keyword group and the second well location keyword group, obtain the well location associated keywords as the third well location keyword group, and obtain the second well location evaluation value corresponding to the second well location keyword group according to the well location layout intelligent analysis model through the third well location keyword group.

[0068] In this embodiment, it should be specifically noted that the well location associated keywords in the first well location keyword group and the second well location keyword group are obtained. The associated keywords are multiple keywords in the first well location keyword group and the second well location keyword group whose rationality values are greater than the preset rationality value after correlation calculation, and the multiple keywords in the first well location keyword group and the second well location keyword group are used as the third well location keyword group. In this embodiment, it should be specifically noted that based on the first well location keyword group and the second well location keyword group, the well location associated keywords are obtained as the third well location keyword group, and the method for obtaining the well location associated keywords is as follows:

[0073] S6: Based on the first well location evaluation value and the third well location keyword group, send the second well location evaluation value corresponding to the second well location keyword group to the management user terminal according to the preset evaluation method to determine the final directional well location layout plan.

[0074] In this embodiment, it should be specifically noted that the well location layout intelligent analysis model obtains the evaluation value of the keyword related to the third well location keyword group in the target knowledge graph, and uses this evaluation value as the first well location evaluation value corresponding to the first well location text, so as to combine the relevance between the first well location text and the second well location text, optimize the rationality of the geothermal extraction and injection well location layout, and provide a more accurate evaluation value for the management personnel, that is, the second well location evaluation value; display the second well location evaluation value to the management personnel according to the preset summary method.

[0077] By adopting the above method, the present invention establishes a plane coordinate system, pre-locates the positions that may be geothermal production and injection wells, and provides a position information basis for subsequent initial processing; based on the layout of the geothermal production and injection well group, obtains the key text of the first well position, and conducts initial processing on the key text of the first well position to obtain the first well position keyword group corresponding to the key text of the first well position. Thus, through the well position layout intelligent analysis model, obtains the first well position evaluation value corresponding to the key text of the first well position according to the first well position keyword group; obtains the key text of the second well position and conducts initial processing on the key text of the second well position to obtain the second well position keyword group corresponding to the key text of the second well position, and obtains the associated keywords in the first well position keyword group and the second well position keyword group, and constructs a third well position keyword group through the associated keywords.
