[0030] Embodiment 1

[0031] Figure 1 This is a flow chart of an oilfield project evaluation method provided by the first embodiment of the present invention. This embodiment is applicable to the situation of evaluating and optimizing the benefits of oilfield projects. The method can be executed by an oilfield project evaluation device. The oilfield project evaluation device can be implemented in the form of hardware and / or software. The oilfield project evaluation device can be configured in a terminal and / or a server. Figure 1 As shown, the method includes:

[0032] S110 . For each to-be-applied project in each oil field, obtain a first prediction data set and a second prediction data set corresponding to the current to-be-applied project under different conditions.

[0033] Among them, the project to be applied can be understood as an oil field project to be developed and applied. The project to be applied can be any oil and gas development project for the oil field. In this embodiment, the project to be applied can be an overseas oil project. Different conditions can include maintaining the current mining status condition and changing the current mining status condition. Maintaining the current mining status condition can be understood as mining based on the existing oil wells, and can also be understood as mining without drilling new oil wells. On the contrary, changing the current mining status condition can be understood as mining under the condition of drilling at least one new well. The first prediction data set can be understood as a data set obtained by predicting the operating status of the corresponding oil field in the future preset time period under the condition of maintaining the current mining status of the current project to be applied. Correspondingly, the second prediction data set can be understood as a data set after the current project to be applied predicts the operating status of the corresponding oil field in the future preset time period under the condition of changing the current mining status. Optionally, both the first prediction data set and the second prediction data set include oil and gas production prediction data, input resource prediction data, and cost information corresponding to the operation.

[0034] For example, assuming that the current oil field includes 10 existing wells and the preset time period can be one year, the first prediction data set corresponding to the project to be applied in the current oil field under the condition of maintaining the current exploitation status may include the oil and gas production forecast data of the 10 wells in the current oil field in the next year, the resource forecast data invested in the exploitation of the 10 wells, and the cost information corresponding to the exploitation operations performed on the 10 wells; further, assuming that the current oil field is expected to add one well in the next year, it can be determined that the current oil field has changed the current exploitation status. At this time, the second prediction data set corresponding to the project to be applied corresponding to the current oil field under the condition of changing the current exploitation status may include the oil and gas production forecast data of the 11 wells in the current oil field in the next year, the resource forecast data invested in the exploitation of the 11 wells, and the cost information corresponding to the exploitation operations performed on the 11 wells.

[0035] In practical applications, in order to reflect the influence of the three parameters of oil and gas production, input resource value and cost information corresponding to the operation on the project benefit evaluation process, the predetermined oil and gas production prediction interval, input resource value prediction interval and cost information prediction interval corresponding to the operation can be sampled and processed, and then, the first prediction data set and the second prediction data set can be constructed based on the sampled data.

[0036] On the basis of the above technical solutions, it also includes: obtaining a first data set to be processed and a second data set to be processed under different conditions for the current project to be applied; processing the first data set to be processed and the second data set to be processed respectively according to a preset data sampling method to construct a first prediction data set and a second prediction data set corresponding to the current project to be applied.

[0037] Among them, the first data set to be processed can be understood as a data interval data set obtained after the current project to be applied predicts the operating status of the corresponding oil field in the future preset time period under the condition of maintaining the current mining status. Optionally, the first data set to be processed may include a first oil and gas production prediction interval, a first input resource prediction interval, and a cost information prediction interval corresponding to the first operation. Correspondingly, the second data set to be processed can be understood as a data interval data set obtained after the current project to be applied predicts the operating status of the corresponding oil field in the future preset time period under the condition of changing the current mining status. Optionally, the second data set to be processed may include a second oil and gas production prediction interval, a second input resource prediction interval, and a cost information prediction interval corresponding to the second operation. The preset data sampling method may be a predetermined data sampling method. The preset data sampling method may be an arbitrary data sampling method, and optionally, the preset data sampling method may be randomly adopted based on a probability distribution function of corresponding key parameters. Among them, the key parameters may be oil and gas production, input resources, and cost information corresponding to the operation.

[0038] In practical applications, we can first obtain the first data set to be processed corresponding to the current project to be applied under the condition of maintaining the current mining status, and the second data set to be processed corresponding to the current project to be applied under the condition of changing the current mining status. Furthermore, for the data interval corresponding to each key parameter included in the first data set to be processed, we can obtain the probability distribution function corresponding to the current key parameter, and then, we can randomly sample the data interval of the current key parameter according to the probability distribution function to obtain the data set corresponding to the current key parameter. Then, after obtaining the data set corresponding to each key parameter in the first data set to be processed, we can construct the first prediction data set based on each data set. It should be noted that the construction method of the second prediction data set is the same as the construction method of the first prediction data set, and this embodiment will not be described in detail here.

[0039] S120: Retrieve a project evaluation model corresponding to the current project to be applied, and process the first prediction data set and the second prediction data set based on the project evaluation model to determine the benefit increment of the current project to be applied.

[0040] Among them, the project evaluation model can be understood as a model for determining the predicted benefits of the project. The project evaluation model can be a mathematical model constructed based on a preset logical relationship. The preset logical relationship can match the oil field project. Exemplarily, the preset logical relationship can include a logical relationship determined based on the payment attribute value, a logical relationship determined based on the production sharing ratio, and a logical relationship determined based on the cost information corresponding to the technical service. The benefit increment can be understood as the increased benefit of the expansion project compared with the non-expansion project, that is, the benefits at the same time point under the expansion and non-expansion conditions are subtracted, and the benefit increment is obtained. In this embodiment, the benefit increment can be understood as the increased benefit of the current project to be applied in changing the current mining status conditions and maintaining the current development status conditions. The benefits at the same time point under the two conditions of changing the current mining status conditions and maintaining the current mining status conditions are subtracted, and the benefit increment is obtained.

[0041] In actual applications, for the same oil field, the corresponding project to be applied can be a project built based on different project income and expenditure types, and each project income and expenditure type can correspond to a corresponding project evaluation model. Therefore, when calling the project evaluation model corresponding to the current project to be applied, it can be called according to the project income and expenditure type corresponding to the current project to be applied.

[0042] Optionally, retrieving a project evaluation model corresponding to the current project to be applied includes: determining a project revenue and expenditure type corresponding to the current project to be applied, and retrieving the project evaluation model corresponding to the current project to be applied based on the project revenue and expenditure type.

[0043] The project income expenditure type may be a type that represents the form of project income expenditure. Optionally, the project income expenditure type may include a type corresponding to an expenditure payment attribute value, a type in which output is spent according to a preset ratio, and a type based on cost information corresponding to technical services.

[0044] In practical applications, multiple types of project revenue and expenditure can be determined in advance, and a project evaluation model corresponding to each type of project revenue and expenditure can be constructed. Furthermore, a mapping relationship between the project revenue and expenditure type and the project evaluation model can be established and stored in a database. Furthermore, in the case of determining the current project to be applied, the project revenue and expenditure type can be determined based on the project information included in the current project to be applied, and then the project evaluation model corresponding to the current project to be applied can be determined and retrieved based on the determined project revenue and expenditure type and the mapping relationship between the pre-established project revenue and expenditure type and the project evaluation model.

[0045] Furthermore, after obtaining the project evaluation model corresponding to the current project to be applied, the first prediction data set corresponding to the current project to be applied under the condition of maintaining the current mining status can be input into the acquired project evaluation model, and then the first benefit of the current project to be applied under the condition of maintaining the current mining status can be obtained; further, the second prediction data set corresponding to the current project to be applied under the condition of changing the current mining status can be input into the acquired project evaluation model, and then the second benefit corresponding to the current project to be applied under the condition of changing the current mining status can be obtained. Further, the difference between the second benefit and the second benefit can be determined, and the difference can be used as the benefit increment of the current project to be applied.

[0046] S130 , based on preset constraints and optimization functions corresponding to various optimization objectives, processing the benefit increments of all the projects to be applied, and determining the identifiers of the projects to be applied corresponding to the target benefit increments.

[0047] Among them, the preset constraints can be understood as pre-set conditions that limit the range of variables involved in project optimization. In this embodiment, the preset constraints may include upper and lower limit constraints on oil and gas production, upper limit constraints on input resources, and constraints on whether to change the current mining status. The optimization target can be understood as a predetermined target used when determining the optimal project to be applied among all projects to be applied. In this embodiment, the optimization target may include the maximum net present value, the maximum net present value rate, the maximum preference for the area where the project to be applied is located, and the minimum risk value for the area where the project to be applied is located. Correspondingly, the optimization function can be understood as an objective function corresponding to the optimization target. The identifier of the project to be applied can be identification information for locating the project to be applied. The identifier of the project to be applied can be any form of identification information, and optionally, it can include numbers, letters or other characters.

[0048] In practical applications, after determining the incremental benefits of all projects to be applied, the incremental benefits of all projects to be applied can be processed according to the preset constraints and optimization objectives to evaluate the benefits of all projects to be applied. It should be noted that the optimization objectives set for the benefit evaluation of the projects to be applied include multiple optimization objectives. At this time, the benefit evaluation of the projects to be applied is multi-objective optimization. In order to transform the multi-objective optimization into a single-objective optimization, so as to achieve the effect of minimizing the deviation between the final predicted value and the target value under limited resource conditions, the weights corresponding to each optimization objective can be pre-set according to the project optimization requirements. Then, the target optimization function can be determined according to the optimization function corresponding to each optimization objective and the corresponding weight, so as to evaluate the benefits of all projects to be applied based on the target optimization function and the preset constraints.

[0049] Optionally, the optimization objectives include a first optimization objective, a second optimization objective, a third optimization objective and a fourth optimization objective; accordingly, based on preset constraints and the optimization functions corresponding to each optimization objective, the benefit increments of all projects to be applied are processed to determine the identifier of the project to be applied corresponding to the target benefit increment, including: determining the benefit increment rate corresponding to each project to be applied according to the benefit increment corresponding to each project to be applied, and obtaining the regional preference weight value and the regional risk index value corresponding to each project to be applied; determining the target optimization function according to the optimization function corresponding to the first optimization objective, the optimization function corresponding to the second optimization objective, the optimization function corresponding to the third optimization objective and the optimization function corresponding to the fourth optimization objective; based on the preset constraints and the target optimization function, the benefit increments, benefit increment rates, regional weight values ​​and regional risk index values ​​corresponding to all projects to be applied are processed to determine the identifier of the project to be applied corresponding to the target benefit increment.

[0050] Among them, the first optimization goal can be understood as the goal of optimizing the benefit increment of the application project. The second optimization goal can be understood as the goal of optimizing the benefit increment rate of the application project. The third optimization goal can be understood as the goal of optimizing the preference for the region where the application project is located. The fourth optimization goal can be understood as the goal of optimizing the risk index value of the region where the application project is located. The benefit increment rate can be understood as the ratio between the benefit increment and the input resource value. The benefit increment rate can also be understood as the net present value rate, that is, the ratio between the net present value of the project and the original input resource value of the project. The regional preference weight value can be understood as the value obtained after the regional preference degree is digitized, that is, the regional preference degree is represented by the numerical value. For example, assuming that all the projects to be applied correspond to five areas, namely, area 1, area 2, area 3, area 4 and area 5, the preference levels of these five areas are arranged in order from large to small to obtain area 1, area 3, area 4, area 2 and area 5. Then, according to the arrangement order of the preference levels, a selection can be made from 1-10, and the weight value corresponding to area 1 can be 2, the weight value corresponding to area 3 can be 4, the weight value corresponding to area 3 can be 6, the weight value corresponding to area 2 can be 8, and the weight value corresponding to area 5 can be 10. It should be noted that the regional preference weight value can be customized based on user needs. For different users, after obtaining the same all the projects to be applied, the weight value corresponding to the area where each project to be applied is located may be different.

[0051] Among them, the regional risk index value can be understood as a comprehensive risk index value that characterizes all risks included in the region. It should be noted that the regional preference weight value can be pre-determined and stored in the database for the region where the project to be applied is located. During the project evaluation process, it can be directly retrieved from the database of the region where the project to be applied is located.

[0052] In actual applications, after obtaining the incremental benefits of all projects to be applied, for each project to be applied, the ratio between the incremental benefit corresponding to the current project to be applied and the difference between the second input resource prediction value and the first input resource prediction value can be determined, and then the incremental benefit rate corresponding to the current project to be applied can be obtained. After that, the predetermined regional preference weight value and regional risk index value of the current project to be applied can be obtained.

[0053] Further, the first weight corresponding to the first optimization target, the second weight corresponding to the second optimization target, the third weight corresponding to the third optimization target, and the fourth weight corresponding to the fourth optimization target can be determined, and the first weight is multiplied by the optimization function corresponding to the first optimization target to obtain the first optimization function to be processed, the second weight is multiplied by the optimization function corresponding to the second optimization target to obtain the second optimization function to be processed, the third weight is multiplied by the optimization function corresponding to the third optimization target to obtain the third optimization function to be processed, and the fourth weight is multiplied by the optimization function corresponding to the fourth optimization target to obtain the fourth optimization function to be processed. Furthermore, the first optimization function to be processed, the second optimization function to be processed, the third optimization function to be processed, and the fourth optimization function to be processed can be added together to obtain the target optimization function.

[0054] Furthermore, the benefit increments, benefit increment rates, regional preference weight values ​​and regional risk index values ​​of all projects to be applied can be input into the target optimization function, and the target optimization function can be optimized according to preset constraints to obtain the identification of the project to be applied corresponding to the target benefit increment.

[0055] Exemplarily, the target optimization function can be determined based on the following formula:

[0056] F=a1F1+a2F2+a3F3+a4F4

[0057]

[0058]

[0059]

[0060]

[0061] Wherein, F represents the target optimization function, a1 represents the first weight, F1 represents the optimization function corresponding to the first optimization target, a2 represents the second weight, F2 represents the optimization function corresponding to the second optimization target, a3 represents the third weight, F3 represents the optimization function corresponding to the third optimization target, a4 represents the fourth weight, F4 represents the optimization function corresponding to the fourth optimization target; NPV i represents the benefit increment of the project to be applied, i represents the identifier of the current project to be applied, and x i Indicates whether to change the current mining status, x i It is 0 or 1, 0 means maintaining the current mining status, 1 means changing the current mining status, NPVR i Represents the incremental benefit rate of the project to be applied, PR i Indicates the preference weight value of the project to be applied, RISK i Indicates the risk indicator value of the project to be applied.

[0062] Exemplarily, the preset constraint condition can be determined based on the following formula:

[0063]

[0064]

[0065] Among them, PRO_DOWN represents the lower limit of oil and gas production, PRO_UP represents the upper limit of oil and gas production, and PRO i Indicates the forecast value of oil and gas production of the project to be applied, CAPEX i represents the predicted value of the input resources for the project to be applied, CAPEX_UP represents the upper limit of the input resources, and x i Is 0 or 1.

[0066] S140: Determine a target project to be applied based on the identification of the project to be applied, and perform project development based on the target project to be applied.

[0067] The target application project can be understood as an application project that meets various target optimization objectives and preset constraints. It should be noted that the number of the obtained application project identifiers can be one or more, so the number of the target application projects is also one or more.

[0068] In practical applications, after obtaining the identification of the project to be applied, the project to be applied corresponding to the identification of the project to be applied can be determined according to the association relationship between the project identification and the project established in advance, and the determined project to be applied can be used as the target project to be applied. Furthermore, the corresponding oil field can be developed according to the target project to be applied.

[0069] The technical solution of the embodiment of the present invention obtains the first prediction data set and the second prediction data set corresponding to the current project to be applied under different conditions for each project to be applied in each oil field, and then retrieves the project evaluation model corresponding to the current project to be applied, and processes the first prediction data set and the second prediction data set based on the project evaluation model to determine the benefit increment of the current project to be applied; based on the preset constraint conditions and the optimization function corresponding to each optimization target, the benefit increment of all projects to be applied is processed to determine the identifier of the project to be applied corresponding to the target benefit increment; based on the identifier of the project to be applied, the target project to be applied is determined, and the project development is carried out based on the target project to be applied, which solves the problem that the original domestic project single well benefit evaluation method in the related technology lacks guidance for the single well evaluation of overseas projects, and then the benefits of overseas oil projects cannot be accurately evaluated, affecting the oilfield development efficiency, etc., and achieves the effect of accurately predicting the project benefits, and achieves the effect of predicting the project benefits based on different project evaluation models. At the same time, it also achieves the effect of determining the optimization project in the presence of multiple projects, and achieves the effect of improving the oilfield development benefit on the basis of reducing the oilfield development cost.

[0070] Embodiment 2

[0071] Figure 2 This is a flow chart of an oilfield project evaluation method provided by the second embodiment of the present invention, and based on the above embodiment, S120 is further refined. The technical terms that are the same as or corresponding to the above embodiment are not repeated here.

[0072] like Figure 2 As shown, the method includes:

[0073] S210 . For each to-be-applied project of each oil field, obtain a first prediction data set and a second prediction data set corresponding to the current to-be-applied project under different conditions.

[0074] S220: Retrieve a project evaluation model corresponding to the current project to be applied, and process the first prediction data set based on the project evaluation model to obtain a first prediction benefit corresponding to the current project to be applied.

[0075] The first prediction data set includes the first oil and gas production prediction value, the first input resource prediction value and the cost information corresponding to the first operation. The first prediction benefit can be understood as the corresponding project prediction benefit of the current project to be applied under the condition of maintaining the current mining status in the future preset time period.

[0076] In actual applications, after determining the current project to be applied and calling the project evaluation model corresponding to the current project to be applied, the first prediction data set can be processed based on the project evaluation model, and then the first prediction benefit corresponding to the current project to be applied can be obtained.

[0077] In this embodiment, the project evaluation model may include a first evaluation model, a second evaluation model and a third evaluation model. When the project evaluation model corresponding to the current project to be applied is a different evaluation model, the corresponding method for determining the first prediction efficiency also changes accordingly. These project evaluation models may be described in detail below.

[0079] Among them, the first evaluation model can be understood as a model for evaluating project benefits based on the payment attributes of oil and gas projects. The first preset ratio can be understood as a preset ratio of the payment attribute values ​​of oil and gas projects. The first payment attribute value can be understood as the value that needs to be paid to the region under the condition of developing the current project to be applied. The second preset ratio can be understood as the oil and gas profit sharing ratio. The first preset value and the second preset value can be understood as the values ​​corresponding to the different payment attributes of the project to be applied.

[0080] In practical applications, when the project evaluation model is the first evaluation model, the project benefits of the project to be applied can be evaluated from the payment attribute. Specifically, the product between the first oil and gas production forecast value and the first forecast ratio can be determined, and the obtained product can be used as the first payment attribute value. Afterwards, the difference between the first oil and gas production forecast value and the first payment attribute value can be determined, and the obtained difference can be the oil and gas cost value obtained after paying a part of the value of the current project to be applied, and the value can be used as the first value to be processed. Afterwards, the product between the first value to be processed and the second preset ratio can be determined, and the obtained product can be used as the first oil and gas recovery value. Afterwards, the difference between the first value to be processed and the first oil and gas recovery value is determined to obtain the second value to be processed, and the difference between the second value to be processed and the first preset value is determined to obtain the third value to be processed.

The third preset ratio can be understood as a preset oil and gas cost recovery ratio. The third preset ratio can be associated with the area corresponding to the project to be applied, that is, different oil and gas cost recovery ratios can be corresponding to different areas. The fourth preset ratio can be understood as the oil and gas profit sharing ratio. The third preset value can be a predetermined project payment attribute value.

[0083] In practical applications, when the project evaluation model is the second evaluation model, the project benefits of the project to be applied can be evaluated from the perspective of production sharing. Specifically, the product between the first oil and gas production forecast value and the third forecast ratio can be determined, and the obtained product can be used as the second oil and gas recovery value. Afterwards, the difference between the first oil and gas production forecast value and the second oil and gas recovery value can be determined, and the obtained difference can be the total profit value of the current project to be applied, and the value can be used as the fourth value to be processed. Afterwards, the product between the fourth value to be processed and the fourth preset ratio can be determined, and the obtained product can be the profit value that the owner of the current project to be applied should get, and the value can be used as the fifth value to be processed. Afterwards, the second oil and gas recovery value can be added to the fifth value to be processed to obtain the second total recovery value. Afterwards, the first input resource forecast value, the cost information corresponding to the first operation, and the third preset value can be added to obtain the second total input value. Finally, the difference between the second total recovery value and the second total input value is determined to obtain the first predicted benefit.

[0084] Optionally, when the project evaluation model is the third evaluation model, the first prediction data set is processed based on the project evaluation model to obtain the first predicted benefit corresponding to the current project to be applied, including: when the project evaluation model is the third evaluation model, determining the product of the first oil and gas production prediction value and the fifth preset ratio to obtain a third oil and gas recovery value; determining the difference between the first oil and gas production prediction value and the third oil and gas recovery value to obtain a sixth value to be processed; determining the product between the sixth value to be processed and the sixth preset ratio to obtain a seventh value to be processed; adding the third oil and gas recovery value and the seventh value to be processed to obtain a third total recovery value; adding the first input resource prediction value, the cost information corresponding to the first operation, and the fourth preset value to obtain a third total input value, and determining the difference between the third total recovery value and the third total input value to obtain the first predicted benefit.

[0085] Among them, the third evaluation model can be understood as a model for evaluating project benefits based on the technical service aspects of oil and gas projects. The fifth preset ratio can be understood as a preset oil and gas cost recovery ratio. The fifth preset ratio can be associated with the region corresponding to the project to be applied, that is, different oil and gas cost recovery ratios can correspond to different regions. The sixth preset ratio can be understood as the oil and gas profit sharing ratio. The fourth preset value can be a predetermined project payment attribute value.

[0087] The second prediction data set includes the second oil and gas production prediction value, the second input resource prediction value and the cost information corresponding to the second operation. The second prediction benefit can be understood as the corresponding project prediction benefit of the current project to be applied under the condition of changing the current mining status in the future preset time period.

[0088] In practical applications, the second prediction data set is processed based on the project evaluation model to obtain the second prediction benefit, which is the same as step S220 and will not be described in detail in this embodiment.

[0089] S240: Determine the difference between the second predicted benefit and the first predicted benefit to obtain the benefit increment of the current project to be applied.

[0090] In practical applications, after determining the first predicted benefit and the second predicted benefit of the current project to be applied, the difference between the second predicted benefit and the first predicted benefit can be determined, thereby obtaining the benefit increment of the current project to be applied.

[0091] It should be noted that since the prediction data set is constructed based on data sampling, the prediction data set includes multiple groups of data, each of which may include an oil and gas production forecast value, an input resource forecast value, and cost information corresponding to an operation. Therefore, for the current project to be applied, the number of corresponding benefit increments can match the number of sampled data points. At this time, a probability distribution curve can be determined based on the multiple benefit increments obtained, and then data can be extracted from the probability distribution curve according to a preset data extraction method to obtain the benefit increment corresponding to the current project to be applied. Among them, the preset data extraction method can be a median method.
