Description

Technical Field

[0001] The present invention relates to the field of data processing technology, and in particular to a method, device and electronic equipment for exploration resource evaluation and basic geological data storage. Background Art

[0002] In exploration resource evaluation, evaluation units are usually organized according to a certain evaluation hierarchy. At present, most software uses files or databases to obtain geological objects and divides them into levels according to geological types. The processing of the hierarchy and parent-child relationship between geological objects and the input of evaluation unit attributes is relatively simple, with insufficient structuring, and does not reflect the hierarchical relationship between geological objects. Different exploration resource evaluation activities have a sequence, and the existing software does not fully reflect the process of these activities, and does not organize these activities in a unified manner for classification and sorting. The evaluation object and the evaluation activity have a one-to-many nature. The existing software usually stores the evaluation records of a certain evaluation object, and some software does not implement the one-to-many mode; when evaluating a geological object, the result will replace the previous result. Other software that implements the storage of historical evaluation records does not make good use of historical data for scoring reference.

[0003] The development and application of geographic information systems have led to the continuous growth of spatial data. The storage and query mode of massive spatial data has become very important, which is also the bottleneck of the development of geographic information systems. The existing spatial data storage and query do not make full use of the location information of spatial data objects, the storage structure is not high enough, and the efficiency of query also needs to be improved. In terms of version management, it is not enough. For the addition, modification and deletion of spatial data elements, incremental management is also required, and the existing geographic information system does not achieve this well. How to design efficient spatial data storage and query mode, improve the speed of data import, loading, rendering, and query, support multi-version recovery, storage and backup of spatial data change operations, and provide more flexible spatial data editing functions, has become the first problem to be solved in geographic information systems.

[0004] The storage of logging, seismic and interpretation data has gone through the process of optical paper storage technology, analog tape storage technology, digital open-reel tape storage technology, cassette tape storage technology, disk storage technology, etc. With the growth of data volume, geological researchers are now facing TB or even PB-level data. When the existing software stores logging, seismic and interpretation data in the database, its structure design does not take too much consideration, and there is room for improvement in the degree of structuring and efficiency.

[0005] Basin simulation is based on physical and chemical geological mechanisms. Computers quantitatively simulate the formation and evolution of oil and gas basins, the generation, migration and accumulation of hydrocarbons in time and space to reveal the nature of oil and gas laws in basins. In the process of basin simulation, due to the huge amount of basin data, it is necessary to organize basin simulation data reasonably. There are large overheads in data storage and calculation, so some space and efficiency optimization are needed to meet modeling requirements.

[0006] In order to realize basin-level, content-oriented basic data storage and analysis, achieve exploration understanding adjustment driven by real-time data, assist in the implementation of exploration direction, and integrate target analysis and resource evaluation into deployment planning and decision-making processes, it is necessary to better unify the management of exploration resource evaluation data and basic geological data, realize basic data storage from single well to basin level, and realize the integration of exploration evaluation and deployment decision-making.

[0007] In the exploration and resource evaluation part, it is necessary to support the hierarchical relationship of geological objects, the process of resource evaluation activities, and the one-to-many nature of geological objects and resource evaluation activities. In the basic geological and spatial data part, a spatial data storage method that better utilizes the location information of spatial data objects, establishes more flexible indexes, has more complete version management functions, and supports backup and incremental recovery of spatial data editing operations is needed; a storage structure is more reasonable, and the class structure design can better reflect the data hierarchy and correlation. The storage and management method of logging, seismic and interpretation results data needs to be realized; efficient basin modeling data structure design and spatial efficiency optimization are needed.

[0008] In view of this, a method, device, electronic device and readable storage medium for exploration resource evaluation and basic geological data storage are proposed. Summary of the invention

[0076] Embodiment 2

[0077] This embodiment provides a method for exploration resource evaluation and basic geological data storage. The following will explain the technical solution of this application with the ideas of the inventor, which will help those skilled in the art to be familiar with the ideas of this application. Among them, some technical points are explained in detail so that those skilled in the art can fully understand the technical solution of this application.

[0078] Please refer to Figure 1-Figure 7 , the exploration resource evaluation and basic geological data storage method includes the following steps:

[0079] 1. First, proceed to step S110 to construct an overall management structure for exploration resource evaluation and basic geological data, and associate resource evaluation objects with geological data.

[0080] The resource evaluation object is an object system based on geological theory in exploration resource evaluation, which divides the evaluation units into several levels from large to small. According to the different levels of the evaluation units, the evaluation units at all levels are established from top to bottom, such as regions - basins - secondary structural belts - tertiary structural belts - closures - layer closures. For each evaluation unit, there is a corresponding actual geographical scope. Basic geological data refers to data collected in geological exploration such as earthquakes, well logging, and cores, and also has a corresponding actual geographical scope. Therefore, the two can be associated through the geographical scope, and the exploration resource evaluation data and the corresponding basic geological data in the same geographical location can be matched.

[0081] Furthermore, the overall management structure is as follows Figure 2 As shown. In the left part of the assessment object, the first is the basic information of the assessment object, which includes the basic parameters of the object. Object attribute information includes the results of risk assessment, resource assessment, economic assessment, etc. for the corresponding assessment object; assessment activity data records the history of these assessments, including multiple assessment records and corresponding evaluators, assessment time, etc.; templates and reference information include some standard methods used in these assessments, standard templates and other data, and methods and templates can also be customized. In the right part of the geological data basic information, various types of geological data are stored, and each piece of geological data is associated with the assessment object at the corresponding location according to its geographical location information. Basic geological data includes various types such as seismic, well logging, core, basin simulation, geographic information, contour lines, etc., which also correspond to different storage and management structures.

[0082] 2. Next, proceed to step S111, storage of exploration resource evaluation data; wherein the storage structure diagram is as follows Figure 3 shown.

[0083] The basic information table of geological objects (i_el) stores the basic data of each geological object. The geological objects are organized and created in sequence in a tree structure, and the parent-child relationship between geological objects is constructed to reflect the hierarchical relationship between different geological objects.

[0084] Among them, when establishing the resource evaluation object, the attribute information of the evaluation unit can be entered. For evaluation units of different levels, the types of geological information entered are also differentiated. For example, when a new basin-level evaluation unit is established, the information entered includes basic information, analog overview, basic geology, source data, reservoir data, caprock data, preservation conditions, closure data, etc. The entered information is stored in a series of resource evaluation object attribute tables in the figure. For a specific type of resource evaluation object, there is also its own unique attribute information. For example, the closure object attributes and block object attributes in the figure are a series of attribute tables for specific types.

[0085] In one embodiment, the relevant information of the assessment object can also be calculated through risk assessment, resource assessment, economic assessment and other modules, and the results will be stored in the corresponding assessment object attribute table. These attribute tables only store the attribute information obtained from the latest assessment activity or a user-specified assessment activity, and the historical evaluation results are stored in a series of record tables related to the assessment activities on the right. Among them, the assessment object evaluation information table (i_el_evaluation) supports the storage of evaluation results of the same assessment object by different users, and is combined with the assessment object basic information table (i_el) to form the assessment object main information view (i_el_evaluation_view), realizing multiple sets of evaluation information of different users of the assessment object in a one-to-many form.

[0086] In one embodiment, some of the asset assessment object attribute tables can also realize one-to-many. For example, the asset assessment object-factor table (i_el_factor) records the relevant results of the probability of oil and gas being calculated by using different evaluation and scoring methods for geological objects. Each geological object can be evaluated using multiple scoring templates, and the results obtained by different templates can be stored in the asset assessment object-factor table (i_el_factor). Therefore, it is also connected to the asset assessment object table through a primary and foreign key to represent a one-to-many mode. The scoring template is stored in the evaluation factor template table (r_quick_template).

[0087] It is feasible to organize the evaluation work according to the business process of the evaluation activity for different evaluation units. The main business processes include: trap management, oil and gas content evaluation, resource calculation, economic evaluation, optimization decision and post-drilling evaluation, etc. The business processes of the evaluation activities corresponding to the evaluation units of different levels are also different. The basic information table of the evaluation object (i_el) and the evaluation activity record table are connected by primary and foreign keys, reflecting the one-to-many nature between the evaluation object and the evaluation activity. An evaluation unit can conduct multiple evaluation activities, including evaluation activities under different users, different times and different parameter settings. The evaluation activity record table stores the record index and basic information of each evaluation activity. The specific information is stored in the evaluation activity parameter table, resource evaluation record table and risk evaluation record table. These three sets of tables are also connected to the evaluation activity record table through primary and foreign keys. The resource evaluation record table mainly stores the evaluation results related to the resource content of the geological object, and the risk evaluation record mainly stores the evaluation results of the oil and gas content of the geological object. In addition, a series of graphs and tables established during the evaluation activities are stored in the chart records, such as Bayesian network, probability tree, decision tree, etc.

[0088] Preferably, some templates are used when conducting the assessment activities, such as the activity tree template that specifies different assessment activity processes for different types of objects, the evaluation template for oil and gas content evaluation and the scoring parameters therein, the template for resource evaluation, etc. These templates are stored in the assessment activity template and reference data in the figure. For example, the evaluation factor template table (r_quick_template) stores the risk assessment template, and the evaluation factor parameter table (r_risk_factor) stores the specific parameters of each risk assessment factor.

[0089] In addition, the management information of the entire database, such as user management, organizational structure, ID number management, etc., is stored in the user management information of the dataset in the figure.

[0090] 3. Then, proceed to step S112 to store geographic information data.

[0091] like Figure 4 As shown in the figure, the geological basic information data is also managed in a hierarchical manner, including a three-level structure, category, theme, layer, corresponding to r_gis_maplayer_category, r_gis_maplayer_theme, and r_gis_maplayer in the figure. Among them, r_gis_maplayer stores specific geological basic information data, and the upper two levels are directory framework nodes. Each geological basic data layer corresponds to a set of layer display configuration parameters, including labels, symbols, graphics, etc., as shown in the figure, and also corresponds to a set of geographic coordinate systems. Since different layers may use different geographic coordinate systems, they need to be recorded to achieve position correspondence between layers and between layers and assessment objects. In addition, there is a user permission table to manage the access rights of different users to different layers.

[0092] For geographic information data, each geographic information data layer corresponds to a set of data tables for storage. The table name of this set of data tables is prefixed with the layer name, so that each piece of data corresponds to a set of tables. This set of tables is mainly composed of the following types of tables:

[0093] (1) Version tree table (xxx_versiontree): The fields in the table include version number, parent version number, operator, operation time, and whether it is the current version. It is used to record the version tree structure;

[0094] (2) Main table: including the main geometry table (xxx_geometry), the fields in the table include geometry number, geometry data, geometry version number, etc.; the main index table (xxx_index), the fields in the table include index grid number, geometry number, index version number, etc.; the main attribute table (xxx_feature), the fields in the table include geometry number, attribute data, attribute version number, etc. These three main tables are used to record the geometry, attribute, and index information of the current version;

[0095] (3) Version table: including the geometry version table (xxx_geometry_ver), index version table (xxx_index_ver), and attribute version table (xxx_feature_ver). The fields in the table are the fields in the corresponding main geometry table, main index table, and main attribute table, and the following two fields are added: operation type, including four data values: add, delete, modify, and no operation; version type, including three data values: table-level version, index-level version, and record-level version. These three version tables are used to back up all spatial data versions;

[0096] (4) Data change table: including the primitive addition table (xxx_geometry_add), primitive modification table (xxx_geometry_update), primitive deletion table (xxx_geometry_del), primitive conflict table (xxx_geometry_conflict), attribute addition table (xxx_feature_add), attribute modification table (xxx_feature_update), attribute deletion table (xxx_feature_del), index addition table (xxx_index_add), and index deletion table (xxx_index_del). The fields in the table are the fields contained in the corresponding main primitive table, main index table, and main attribute table. The following three fields are added on top of them: operator, operation time, and operation version. They are used to store the changes made by users to spatial data. When the version is submitted, the changes will be applied to the main table and version table.

[0097] (5) In addition, there is a configuration information table (xxx_configure) used to record the display and query related configuration of the layer. Through such table structure settings, it is possible to support the trunk and branch version evolution of the geographic information layer, and the version evolution of the layer and element levels.

[0098] 4. Next, proceed to step S113, storing earthquake data.

[0099] like Figure 5As shown in the figure, seismic data consists of the data of each seismic channel and the shape and position data of the survey line and network. The "d_seismic_dataset_survey_basic" in the channel header and network information table is used to store information such as the shape and position of the survey line and network, including the number of lines, the number of channels, the start and end line numbers and channel numbers, the line number and channel number increment, coordinates, range, etc.; the "d_seismic_dataset_survey_detail" is used to store the specific shot check point, dip angle and azimuth of each point in the network; the "d_seismic_dataset_head" table is used to store the seismic channel header information of a seismic data file, including the number of sampling points of the seismic channel, sampling interval, sampling start and end time and other attribute information.

[0100] In one embodiment, the track header and survey network information table is connected to the "d_seismic_dataset_gate" table through a foreign key. Each record in this table represents a seismic data file, including information such as the file path. It is connected to the "d_seismic_dataset" table through a foreign key. "d_seismic_dataset" represents a seismic data set, and it is connected to the "r_seismic_project" table through a foreign key. The "r_seismic_project" table represents a seismic data work area, that is, a seismic data work area is composed of several data sets, and each data set is composed of several seismic data files. "d_seismic_dataset" is connected to the "d_seismic_surveylayer" table through a foreign key to record the scope of the seismic layer, the stored broken line and other information. "d_seismic_surveylayer" is also connected to the "r_seismic_project" table through a foreign key and belongs to the seismic work area.

[0101] In addition, the "d_seismic_wavelet" table stores wavelet data, belongs to the seismic data set, and is connected to the "d_seismic_dataset" table through a foreign key. The "d_seismic_surveylayer_rendering" table, which records the network drawing parameters and other information, is connected to the "d_seismic_surveylayer" table through a foreign key. The profile display configuration table "r_seismic_profile_rendering" stores profile display related parameters such as color, display mode, etc.

[0102] In one embodiment, seismic interpretation result data is stored in "d_seismic_earthmodel", each record represents a seismic interpretation result, and the "r_seismic_project" and "d_seismic_surveylayer" tables are connected through foreign keys. The "d_seismic_earthmodel_feature" that records the specific data of the seismic interpretation results and the "d_seismic_earthmodel_rendering" that records the display mode of the interpretation results are connected to the interpretation results table and the seismic work area table through foreign keys.

[0103] 5. Further, proceed to step S114 to store the logging data.

[0104] like Figure 6 As shown in the figure, the data tables storing the basic information of the well are "d_gis_maplayer_welldata" and "d_gis_maplayer_welldata_extented", which include the well number, well name, location information, depth, altitude, invalid values, etc.; the "d_well_bore" table is the borehole information, which is connected to the well basic information table through a foreign key, indicating that a well has multiple wellheads; the well layer related parameter table records some configuration information and attribute data of the well layer, and these tables are connected to the geological basic information table through a foreign key. For each single well, a series of tables storing well data and well curve data are established with the well name as the prefix, as shown in the figure, where the curve data is stored by "d_well_trace_xxx", including the data of all well logging curves in the well logging, the corresponding data of time depth, the well inclination correction data, etc., and the "d_well_pick_xxx" table stores the sounding, vertical depth and other data; in addition, a well general parameter configuration table is established to store some standard curve names, etc.

[0105] 6. Finally, proceed to step S115 to store basin simulation data.

[0106] like Figure 7 As shown in the figure, "d_basin_simulation_model" stores the model data of basin simulation, each of which represents a model. The input data of basin simulation modeling is a set of geological layers, each of which represents a stratum. Its main data include a two-dimensional grid composed of a set of spatial coordinates, stratigraphic age, geological event type, stratigraphic splitting age interval, local geological event range and type, local refinement range and refinement ratio, and some other geological parameters.

[0107] In one embodiment, the inputted original grid data is stored in "d_basin_model_maplayer". After the data is inputted, the information such as age, shape (griddata), geological event type (geoevent), different geological event ranges (diffpartextent), and different geological event types (diffpartgeoevent) are first added to the grid data to establish the geological horizon, which is stored in "d_basin_model_geo_horizon" to form the geological horizon. Age represents the time when the geological horizon is formed, in millions of years; griddata is represented by a set of xy-direction gridded coordinates, the xy of each grid coordinate point represents the geographical location, and the z represents the depth in the current basin; geoevent values ​​include four types: sedimentation, denudation, virtual layer, and sedimentary discontinuity; diffpartextent is a set of rectangular ranges, each rectangle represents the range of a different geological event; diffpartgeoevent is a set of geological event types, each representing the event type of a different geological event, and the range of value types is the same as geoevent.

[0108] Among them, for a geological layer, there may not be only a single type of geological event in its entire area. For example, there may be sedimentation in some places and erosion in other places. For this case, diffpartextent and diffpartgeoevent need to be added to represent these local areas. diffpartextent and diffpartgeoevent appear in pairs, representing the scope and geological type of a local area respectively.

[0109] Among them, the information of different geological events is stored in "d_basin_model_setting". Then the facies information is configured for the layer, which is stored in "d_basin_model_geo_facemap", and the fault information is configured, which is stored in "d_basin_model_geo_fault". The two adjacent layers above and below are combined into a thickness layer, which is stored in "d_basin_model_blockplayer". It and "d_basin_model_mapplayer" are connected to the model table through foreign keys.

[0110] In one embodiment, the parameter information such as heat flow, temperature, water depth, etc. is stored in the "r_heat_flow", "r_sediment_water_interface_temperayure", and "r_water_paleo_depth" tables in the figure, which are connected to the model table through foreign keys. The related tables "r_geo_litho" and "ref_face_definition" that record lithology respectively realize the defined lithology and the lithology distribution record of the entire grid. "r_behar_kinetics" and "r_pepper_kinetics" store the values ​​of some parameters used in the simulation.

[0111] At this point, the exploration resource evaluation and storage process of basic geological data is completed.
