Description

Technical Field

[0001] This invention relates to the field of oil and gas reservoir exploration and development, and in particular to a method, apparatus, medium, and equipment for rapid assessment of oil and gas fractional reserves. Background Technology

[0002] Currently, oil and gas project shareholding reserve assessment is characterized by a large number of projects, their distribution across different regions globally, diverse contract types, and varying exploration and development statuses. This results in complex assessment data and a variety of assessment methods and tools. Traditional shareholding reserve assessment includes technically recoverable reserves assessment and economic evaluation. For technically recoverable reserves assessment, commonly used static methods include GST, Petrel, and NeuraMap, while dynamic methods include R3, PHDWin, and OFM. Common tools for economic evaluation include Excel and PEEP. Summary of the Invention

[0003] The input and output data formats of various tools are all different. On the one hand, assessors need to collect and analyze reserve data according to the shareholding disclosure rules, and use corresponding tools for calculation, assessment, management, and research. The assessment involves multiple data formats, calculation methods, and nodes, and limited personnel, requiring manual operation, resulting in a large workload for shareholding reserve assessment. On the other hand, during the assessment process, multiple rounds and multiple assessments are required based on data timeliness, the accuracy of assessment tool calculation results, or the achievement of performance indicators, which further increases the workload. For these reasons, the current shareholding reserve assessment cannot meet the needs of shareholding reserve assessment for oil development projects.

[0004] In view of the above problems, the present invention is proposed to provide a method, apparatus, medium, or equipment for rapid assessment of oil and gas fractional reserves that overcomes or at least partially solves the above problems.

[0005] This invention provides a method for rapid assessment of oil and gas reserve proportions, comprising:

[0006] Based on the data input and output standards of various assessment tools, the collected data of the geological blocks to be assessed are transformed into basic data that meet the requirements of integrated import.

[0007] The static and dynamic data of the geological block to be evaluated are input into the selected static method evaluation tool and the corresponding dynamic method evaluation tool, respectively. The technically recoverable reserves evaluation results output by the static method evaluation tool and the dynamic method evaluation tool are compared. If the evaluation error of the two is determined to be unacceptable according to the comparison results, the specified parameters of the static method evaluation tool and the dynamic method evaluation tool are reviewed and adjusted, and the evaluation results are obtained again until the evaluation error of the two meets the requirements, and the adjusted dynamic method evaluation tool is obtained.

[0008] The corresponding economic evaluation tool is determined based on the adjusted dynamic method evaluation tool; the dynamic data of the geological block to be evaluated is input into the adjusted dynamic method evaluation tool to obtain the final technically recoverable reserves and production profile; the production profile and the economic parameters of the geological block to be evaluated are input into the economic evaluation tool to obtain the oil and gas share reserves.

[0009] An optional implementation method involves transforming the collected data from the geological blocks to be evaluated into basic data that meets the requirements for integrated import, based on the data input and output standards of various assessment tools. This includes:

[0011] Based on the input parameter requirements of various evaluation tools, select the required input data for each evaluation tool from the acquired data;

[0012] For the input data of each assessment tool, the data is converted according to the data input unit requirements of the assessment tool, and sorted according to the input order requirements of the assessment tool to obtain the basic data that meets the requirements of integrated import.

[0013] An optional implementation involves inputting the static and dynamic data of the geological block to be evaluated into the selected static method evaluation tool and the corresponding dynamic method evaluation tool, respectively, including:

[0015] Select the input data for the static method assessment tool from the static data of the geological block to be assessed, input the data into the static method assessment tool in the preset input order, and output the technically recoverable reserves assessment results of the static assessment.

[0016] The input data for the dynamic assessment tool is selected from the dynamic data of the geological block to be assessed, and then input into the dynamic assessment tool in a preset input order. The result of the dynamic assessment of the technically recoverable reserves is then output.

[0017] An optional implementation, if the comparison results determine that the evaluation errors of the two methods do not meet the requirements, adjust the specified parameters of the static method evaluation tool and the dynamic method evaluation tool, including:

[0018] The technically recoverable reserves assessment results of static assessment output by the static method assessment tool and the technically recoverable reserves assessment results of dynamic assessment output by the dynamic method assessment tool are compared to determine whether the difference between the two is within the preset difference threshold range.

[0019] If not, use statistical methods to determine the static correlation ranking between static evaluation parameters and static evaluation results in static evaluation tools, and the dynamic correlation ranking between dynamic evaluation parameters and dynamic evaluation results in dynamic evaluation tools.

[0020] Based on the static and dynamic correlation rankings, the evaluation parameters for the specified rankings in the dynamic and static evaluation tools are adjusted.

[0021] An optional implementation, wherein obtaining the production profile based on the final technically recoverable reserves assessment results and historical production data of the geological block to be assessed, includes:

[0022] The recoverable reserves, initial production, decline pattern, and decline rate of the geological block to be evaluated;

[0023] The initial production is obtained based on the historical production data of the geological block to be evaluated. The final technically recoverable reserves assessment result is used to obtain the expected production decline pattern based on the decline pattern of the technically recoverable reserves. The final technically recoverable reserves assessment result is used to obtain the expected production decline rate based on the decline rate. The production profile is obtained based on the initial production, the expected production decline pattern, and the expected production decline rate.

[0024] Optional implementations also include:

[0025] Acquire the changed evaluation parameters and data input through the human-computer interaction interface; based on the changed evaluation parameters and data, re-transform them to obtain basic data that meets the requirements of integrated import; and / or

[0026] The system retrieves batch parameter change files uploaded by users, parses the change files to obtain multiple evaluation parameters that have changed and their corresponding change data, and then re-transforms these multiple evaluation parameters and their corresponding change data to obtain basic data that meets the requirements for integrated import.

[0027] This invention provides a device for rapid assessment of oil and gas reserve proportions, comprising:

[0028] The data conversion module is used to convert the collected data of the geological blocks to be evaluated into static data, dynamic data and economic parameters that meet the requirements of integrated import, according to the data input and output standards of various assessment tools.

[0029] The parameter adjustment module is used to input the static and dynamic data of the geological block to be evaluated into the selected static method assessment tool and the corresponding dynamic method assessment tool, respectively. The technically recoverable reserves assessment results output by the static method assessment tool and the dynamic method assessment tool are compared. If it is determined from the comparison results that the assessment error of the two does not meet the requirements, the specified parameters of the static method assessment tool and the dynamic method assessment tool are adjusted and the assessment results are obtained again until the assessment error of the two meets the requirements, and the adjusted dynamic method assessment tool is obtained.

[0033] The system retrieves batch parameter change files uploaded by users, parses the change files to obtain multiple evaluation parameters that have changed and their corresponding change data, and then re-transforms these multiple evaluation parameters and their corresponding change data to obtain static data, dynamic data, and economic parameters that meet the requirements for integrated import.

[0048] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein.

[0049] To address the problems existing in the prior art, embodiments of the present invention provide a method, apparatus, medium, and equipment for rapid assessment of oil and gas fractional reserves.

[0050] Example 1

[0051] Embodiment 1 of the present invention provides a method for rapid assessment of oil and gas fractional reserves, the process of which is as follows: Figure 1 As shown, it includes the following steps:

[0052] Step S101: Convert the collected data of the geological blocks to be evaluated into data that meets the requirements.

[0053] Based on the data input and output standards of various assessment tools, the collected data of the geological blocks to be assessed are transformed into basic data that meets the requirements for integrated import.

[0054] Step S102: Selection of dynamic and static evaluation tools and parameter adjustment.

[0055] The static and dynamic data of the geological block to be evaluated are input into the selected static method evaluation tool and the corresponding dynamic method evaluation tool, respectively. The technically recoverable reserves evaluation results output by the static method evaluation tool and the dynamic method evaluation tool are compared. If the evaluation error of the two is determined to be unacceptable according to the comparison results, the specified parameters of the static method evaluation tool and the dynamic method evaluation tool are reviewed and adjusted, and the evaluation results are obtained again until the evaluation error of the two meets the requirements, and the adjusted dynamic method evaluation tool is obtained.

[0056] Step S103: Output the evaluation results.

[0057] The corresponding economic evaluation tool is determined based on the adjusted dynamic method evaluation tool; the dynamic data of the geological block to be evaluated is input into the adjusted dynamic method evaluation tool to obtain the final technically recoverable reserves and production profile; the production profile and the economic parameters of the geological block to be evaluated are input into the economic evaluation tool to obtain the oil and gas share reserves.

[0058] In this invention, based on the data input and output standards of various assessment tools, the collected data of the geological blocks to be assessed is transformed into basic data that meets the requirements of integrated import. This automates the selection of input data required by various assessment tools from the data of the geological blocks to be assessed. The technically recoverable reserves assessment results output by static and dynamic assessment tools are compared, and the specified parameters of the static and dynamic assessment tools are adjusted, with the results mutually corroborating each other. This automates the adjustment of the specified parameters of the static and dynamic assessment tools and ensures the accuracy of their output results. Based on the final technically recoverable reserves assessment result output by the adjusted dynamic assessment tool, and based on the final technically recoverable reserves assessment result and historical production data, a projected production profile is obtained. This projected production profile and the economic parameters of the geological blocks to be assessed are input into the economic assessment tool to automatically obtain the oil and gas share reserves. This invention automates the selection of input data required by each assessment tool from the data of the geological blocks to be assessed; it automates the adjustment of the specified parameters of each assessment tool, ensuring the accuracy of the oil and gas share reserve assessment results; thereby reducing manual workload and improving the accuracy of the assessment results.

[0059] Example 2

[0060] Embodiment 2 of the present invention provides a specific implementation process of a rapid assessment method for oil and gas fractional reserves, the process of which is as follows: Figure 2 As shown, its specific structure is as follows: Figure 3 As shown, the process includes the following steps:

[0061] Step S201: Transform the collected data of the geological blocks to be evaluated into data that meets the requirements.

[0062] Based on the data input and output standards of various assessment tools, the collected data of the geological blocks to be assessed are transformed into basic data that meets the requirements for integrated import.

[0063] Specifically, the process involves acquiring data on the geological blocks to be evaluated input by the user or data on the geological blocks to be evaluated stored in the database; selecting the required input data for each evaluation tool from the acquired data based on the input parameter requirements of various evaluation tools; and converting the input data for each evaluation tool according to the data input unit requirements of the evaluation tool and sorting it according to the input order requirements of the evaluation tool to obtain basic data that meets the requirements of integrated import.

[0064] The system acquires data on the geological blocks to be evaluated input by the user and data on the geological blocks to be evaluated stored in the database. Based on the input parameter requirements of various evaluation tools, it selects the input data required by each evaluation tool from the acquired data. For the input data of each evaluation tool, it converts the data according to the data input unit requirements of the evaluation tool and sorts it according to the input order requirements of the evaluation tool to obtain basic data that meets the requirements of integrated import.

[0065] like Figure 3 The illustrated rapid reserve assessment device collects and converts geological block data through a data exchange interface between reserve assessment software programs. This interface is developed based on existing technology; it involves establishing a standardized data interface protocol according to the input and output standards of the assessment software, constructing a data conversion interface based on this protocol, and then using this interface to convert the data. For example, standards are established based on the required data formats of each assessment tool, and a data conversion interface is developed accordingly. The interface selects the required input data for each tool from the acquired data, converts the input data according to the data input unit requirements of the assessment tools, and sorts it according to the input order requirements of the tools, resulting in basic data that meets the requirements for integrated import. The assessment object conversion matching process selects the geological blocks to be assessed from among numerous geological blocks. The data exchange interface adapts to various data formats, ensuring correct data import and export.

[0066] Step S202: Selection of static and dynamic evaluation tools and parameter adjustment.

[0067] The basic data of the geological block to be evaluated are input into the selected static method evaluation tool and the corresponding dynamic method evaluation tool, respectively. The technically recoverable reserves evaluation results output by the static method evaluation tool and the dynamic method evaluation tool are compared. If it is determined from the comparison results that the evaluation error of the two does not meet the requirements, the specified parameters of the static method evaluation tool and the dynamic method evaluation tool are adjusted and the evaluation results are obtained again until the evaluation error of the two meets the requirements, and the adjusted dynamic method evaluation tool is obtained.

[0068] The implementation method for inputting the basic data of the geological block to be evaluated into the selected static method assessment tool and the corresponding dynamic method assessment tool is as follows: Based on the correspondence between the static method assessment tool and the dynamic method assessment tool, select the static assessment tool and the corresponding dynamic assessment tool; select the input data of the dynamic method assessment tool from the dynamic data of the geological block to be evaluated, input it into the dynamic method assessment tool according to the preset input order, and output the technically recoverable reserves assessment result of the dynamic assessment; select the input data of the static method assessment tool from the static data of the geological block to be evaluated, input it into the static method assessment tool according to the preset input order, and output the technically recoverable reserves assessment result of the static assessment.

[0069] If the comparison results indicate that the assessment errors of the two methods do not meet the requirements, the specified parameters of the static and dynamic assessment tools will be adjusted. Specifically, the technically recoverable reserves assessment results output by the static method and the technically recoverable reserves assessment results output by the dynamic method will be compared to determine whether the difference between the two is within a preset difference threshold. If not, statistical methods will be used to determine the static correlation ranking between the static assessment parameters and the static assessment results in the static method assessment tool, and the dynamic correlation ranking between the dynamic assessment parameters and the dynamic assessment results in the dynamic method assessment tool. Based on the static and dynamic correlation rankings, the assessment parameters for the specified rankings in both the dynamic and static assessment tools will be adjusted.

[0070] like Figure 3 The rapid resource allocation assessment device shown utilizes a combination of static and dynamic methods for tool selection and parameter adjustment. This combined approach is developed based on the combined static and dynamic assessment techniques. The assessment object, the geological block to be assessed, is determined using assessment unit matching. One dynamic assessment unit typically corresponds to one or more static assessment units. Based on the conversion and matching relationship between dynamic and static assessment units, the dynamic assessment unit and its corresponding static assessment unit are selected. Static method software data analysis utilizes static assessment tools to perform static evaluation of the geological block to be evaluated. In this embodiment, the static assessment tool mainly relies on static data such as seismic data and well logging data. The main model used by the static assessment tool is a geological model, which combines seismic data and well logging data to compare and differentiate production conditions to obtain technically recoverable reserves. Dynamic method software data analysis utilizes dynamic assessment tools to perform dynamic evaluation of the geological block to be evaluated. In this example, the dynamic assessment tool mainly relies on dynamic data such as production volume and water / gas injection volume. The dynamic assessment tool uses time series analysis, dynamic programming, and optimization algorithms to obtain technically recoverable reserves.

[0071] The static and dynamic assessment data analysis comprehensively considers the output results of the dynamic assessment tool and the static assessment tool. Based on actual business needs and data characteristics, it compares, verifies, and optimizes the two assessment results. Utilizing data fusion algorithms, error analysis algorithms, and optimization algorithms (such as gradient descent and genetic algorithms), it ultimately generates reserve assessment results, improving the accuracy and consistency of the assessment. In this implementation, statistical analysis methods and machine learning algorithms are used to analyze the technically recoverable reserves of the dynamic and static assessment tools, adjusting the specified parameters of both tools to obtain technically recoverable reserves that meet the preset error, and adjusting the static and dynamic assessment tools accordingly. For example, if the difference between the two technically recoverable reserves exceeds 10%, further verification of the dynamic method and economic evaluation parameters and models is required for further optimization and adjustment, ultimately yielding recoverable reserves that meet the requirements. Unit change processing and recording stores the assessment results of the dynamic and static assessment tools and displays them to users through a visual terminal.

[0072] The combined evaluation results of static and dynamic methods are as follows: Figure 4 As shown, the geological block to be evaluated is Block A. The static assessment tool used is NeuraMap, and the assessment method is the volumetric method. In the static assessment table, the thickness is 12m, the geological reserves are 755.00MMbbl, the recovery rate is 35.00%, the recoverable reserves are 264.25MMbbl, the cumulative production is 174.00MMbbl, and the remaining recoverable reserves are 90.25MMbbl. The geological block to be evaluated is Block A below the static assessment table. The dynamic assessment tool used was PHDWin, and the assessment method employed was the declining production method. In the dynamic assessment table, the initial production was 87,761.00 bbl / d, the annual decline rate was 22.00%, the recoverable reserves were 282.00 MBBL, the cumulative production was 174.00 MBBL, and the total number of wells drilled was 300. In the graph below the dynamic assessment table, the line graph to the left of the dashed line represents historical production, the starting point to the right of the dashed line represents initial production, and the graph to the right of the dashed line represents predicted production. The line graph is a production profile predicted based on existing producing wells, without considering future drilling and intervention efforts; the dotted line graph is a production profile predicted considering future drilling and intervention efforts. Based on the historical production profile in the line graph to the left of the dashed line and the predicted production profile in the dotted line graph to the right of the dashed line, the recoverable reserves assessed by the dynamic assessment tool were calculated. The recoverable reserves assessed by the static method are 264.25 MBBL, while the recoverable reserves assessed by the dynamic method are 282.00 MBBL. The difference between the two is within 10%, and the recoverable reserves assessment results are reasonable and reliable.

[0073] Step S203: Output the evaluation results.

[0074] The corresponding economic evaluation tool is determined based on the adjusted dynamic method evaluation tool; the dynamic data of the geological block to be evaluated is input into the adjusted dynamic method evaluation tool to obtain the final technically recoverable reserves evaluation result; based on the final technically recoverable reserves evaluation result and production profile; the production profile and the economic parameters of the geological block to be evaluated are input into the economic evaluation tool to obtain the oil and gas share reserves.

[0075] Based on the final technically recoverable reserves assessment results and historical production data of the geological blocks to be assessed, a production profile is obtained, including:

[0076] The recoverable reserves, initial production, decline pattern, and decline rate of the geological block to be evaluated;

[0077] The initial production is obtained based on the historical production data of the geological block to be evaluated. The final technically recoverable reserves assessment result is used to obtain the expected production decline pattern based on the decline pattern of the technically recoverable reserves. The final technically recoverable reserves assessment result is used to obtain the expected production decline rate based on the decline rate. The production profile is obtained based on the initial production, the expected production decline pattern, and the expected production decline rate.

[0078] like Figure 3 The rapid reserve assessment device shown outputs assessment results through a combined dynamic method and economic evaluation. The combined dynamic method and economic evaluation operation is developed based on the technology of combined dynamic method and economic evaluation. Assessment unit matching determines the assessment object, which is the geological block to be assessed. One economic evaluation unit corresponds to one or more dynamic method assessment units. Based on the conversion and matching relationship between dynamic method assessment units and economic evaluation units, dynamic method assessment units and economic evaluation units are matched to select the corresponding economic evaluation tool for the dynamic method assessment tool. Dynamic method software data analysis uses the dynamic method assessment tool to assess technically recoverable reserves and production profiles. Economic evaluation data analysis, based on the production profile, adds costs, investment, contract period, the production capacity of the geological block to be assessed, and economic factors to obtain the oil and gas share reserves. Unit change processing and recording stores the assessment results of the dynamic method assessment tool and the economic evaluation tool, and displays the assessment results to users through a visualization terminal.

[0079] In this embodiment, the economic evaluation tools can employ discounted cash flow (DCF) algorithms, net present value (NPV) algorithms, internal rate of return (IRR) algorithms, and modified IRR algorithms. The DCF algorithm estimates future output, selling prices, development costs, and discount rates to calculate future cash flows, which are then discounted to the present to obtain the economic value of the reserves. The NPV algorithm compares the present value revenue and present value cost of a project to assess its economic benefits. The IRR and modified IRR algorithms evaluate the rate of return on project investment. Sensitivity analysis and risk analysis assess the impact of various factors on the economic evaluation results and potential risks to arrive at the share of reserves.

[0080] The results of the combined evaluation of dynamic method and economic evaluation are as follows: Figure 5 The geological block to be evaluated is Block A. The dynamic evaluation tool used is PHDWin, and the evaluation method is the decreasing method. In the dynamic evaluation table, the initial production is 87,761.00 bbl / d, the annual decrease rate is 22.00%, the recoverable reserves are 282.00 MBBl, the cumulative production is 174.00 MBBl, and the total number of wells is 300. In the figure below the dynamic evaluation table, the line graph to the left of the dashed line is the historical production, the starting point to the right of the dashed line is the initial production, and the graph to the right of the dashed line is the predicted production. The straight line graph is the production profile predicted based on existing producing wells without considering future new drilling and intervention work. The dotted line graph is the production profile predicted considering future new drilling and intervention work. The Peep valuation tool was used in the economic law assessment, and the cash flow method was employed. In the economic law assessment table, the share of reserves is 84,704.00 Mbbl, the product price is $46.85 / bbl, the investment is $121,631.00 M, the cost is $903,000.00 M, the taxes and fees are $1,038,951.00 M, and the cumulative cash flow is $895,859.00 M. The bar chart below the economic law assessment table represents annual output, the dotted line graph next to the horizontal axis represents annual cash flow, and the dotted line graph away from the horizontal axis represents cumulative cash flow.

[0081] Step S204: Update the value of the specified parameter.

[0082] Acquire the changed evaluation parameters and data input through the human-computer interaction interface; based on the changed evaluation parameters and data, re-transform them to obtain basic data that meets the requirements of integrated import; and / or

[0083] The system retrieves batch parameter change files uploaded by users, parses the change files to obtain multiple evaluation parameters that have changed and their corresponding change data, and then re-transforms these multiple evaluation parameters and their corresponding change data to obtain basic data that meets the requirements for integrated import.

[0084] After the parameters are updated, a reassessment can be performed: input the basic data that meets the requirements for integrated import obtained in step S204 into steps S202 and S203 to obtain the oil and gas share reserves.

[0085] Step S204 can be performed or not.

[0086] The specific implementation method in step S204 in this embodiment.

[0087] like Figure 3 The rapid reserve allocation assessment device shown can achieve combined static and dynamic methods, combined dynamic methods and economic evaluation, and integrated reserve allocation assessment. Specifically, the integrated reserve allocation assessment technology involves analyzing data from combined dynamic, static, and economic evaluation methods (either individually or collectively) to ultimately achieve an integrated assessment of multiple methods and obtain oil and gas reserve allocations. The integrated share-based reserve assessment technology determines the assessment object through assessment unit matching, where the assessment object is the geological block to be assessed. Based on the conversion and matching relationships between static, dynamic, and economic assessment tools, static, dynamic, and economic assessment units are matched to select the appropriate tools. Static and dynamic assessment data analysis utilizes both static and dynamic assessment tools to evaluate the geological block; similarly, dynamic and economic assessment data analysis utilizes both dynamic and economic assessment tools. This integrated assessment verifies the consistency of the assessment data and ensures collaborative processing between the various assessment tools to obtain a reasonable assessment result. The dynamic and economic assessment data analysis is described in step S202, and the economic and dynamic assessment data analysis is described in step S203.

[0088] like Figure 3The illustrated rapid reserve assessment device utilizes a rapid assessment parameter management system to adjust one or more basic parameters in batches. It automatically processes the changed assessment parameters and data input through the human-computer interface, transforming them into basic data that meets integrated import requirements. Alternatively, it semi-automatically processes user-uploaded batch parameter change files, parsing them to obtain multiple changed assessment parameters and corresponding data, and then transforming them again to obtain basic data that meets integrated import requirements. A rapid assessment model algorithm generates assessment tools for the geological blocks to be assessed, which then evaluate the blocks to obtain oil and gas reserve share data. The assessment results are recorded and stored, and displayed to users via a visualization terminal. This allows decision-makers to quickly obtain new assessment results based on different scenarios and parameter assumptions, and flexibly adjust and optimize existing results.

[0089] The evaluation results of the integrated quota reserve assessment technology are as follows: Figure 6 As shown, the geological block to be evaluated is Block A. The static assessment tool used is NeuraMap, and the assessment method is the volumetric method. In the static assessment table, the thickness is 12m, the geological reserves are 755.00MMbbl, the recovery rate is 35.00%, the recoverable reserves are 264.25MMbbl, the cumulative production is 174.00MMbbl, and the remaining recoverable reserves are 90.25MMbbl. The geological block to be evaluated is Block A below the static assessment table. The dynamic assessment tool used was PHDWin, and the assessment method was the declining method. In the dynamic assessment table, the initial production was 87,761.00 bbl / d, the annual decline rate was 22.00%, the recoverable reserves were 282.00 MBBl, the cumulative production was 174.00 MBBl, and the total number of wells drilled was 300. In the figure below the dynamic assessment table, the line graph to the left of the dashed line represents the historical production, the starting point to the right of the dashed line represents the initial production, and the graph to the right of the dashed line represents the predicted production profile. The straight line graph is the production profile predicted based on existing producing wells without considering future new drilling and intervention work.
