Description

Technical Field

[0001] The present invention relates to the technical field of oil and gas exploration and development, and in particular to a method and device for generating a legend for an oilfield mining status map. Background Art

[0002] Oilfield production status maps are often used to assist in geological research on oil and gas field development. A common approach involves collecting and organizing data such as well names and categories, importing this data into specialized software, and then using pie charts of varying radii to represent the fluid production of each well. Existing techniques, such as those proposed in "Microcomputer Applications," combine the functions of MapViewer software with parameter settings to create oil and gas field production status maps. However, this method requires complex parameter configuration and can result in occlusion issues.

[0003] Based on this, the existing technology has the following defects: First, the process of acquiring, screening and organizing oilfield production data takes too long; second, parameters such as cumulative production and daily production cannot be displayed at the same time, and information is lacking; third, the layout of the maps is unreasonable, resulting in some maps being too large, blocking the maps of neighboring wells, and increasing the difficulty of map recognition and reading.

[0004] Therefore, there is an urgent need for a new legend generation method for oil field production status maps. Summary of the Invention

In the absence of conflict, the embodiments of the present invention and the technical features in the embodiments can be combined with each other.

[0049] Figure 1 FIG. 1 is a flow chart of a method for generating a legend for an oilfield mining status map provided by an embodiment of the present invention. Figure 1 As shown in FIG, the legend generation method of the oilfield production status map includes the following steps:

[0050] S1. Obtaining oilfield production data from a database based on a user's production data request, and automatically verifying the oilfield production data based on data cleaning technology to confirm whether the oilfield production data meets availability conditions, wherein the availability conditions include a first condition, a second condition, and a third condition. The first condition is that the oilfield production data meets a requirement for accuracy, the second condition is that the oilfield production data meets a requirement for non-duplication, and the third condition is that the oilfield production data meets a requirement for completeness. The oilfield production data includes well location data and indicator data necessary for an oilfield production status map.

[0051] In an embodiment of the present invention, the database is the A2 database in the oil, gas and water well production data management system. The embodiment of the present invention responds to the user's production data request and obtains the corresponding oilfield production data from the corresponding database according to the production data request.

[0052] The oilfield production data includes the necessary well location data and indicator data for the oilfield production status map, wherein the well location data includes the oil production plant, operating area, block, combination unit, well location name and the corresponding number of well locations, etc. The indicator data includes cumulative production and daily production, such as daily liquid production, daily oil production, cumulative liquid production, cumulative oil production of oil production wells, daily water injection and cumulative water injection of injection wells, cumulative liquid production and cumulative oil production of shut-down oil production wells, cumulative water injection of shut-down injection wells, etc.

[0053] Specifically, the embodiment of the present invention needs to verify the user's identity information and the corresponding access permission level before feeding back the oilfield production data. The embodiment of the present invention obtains the oilfield production data from the database based on the user's production data request, including linking to the database according to the user's production data request, verifying the user's access permission level, and for users who meet the access permission level, parsing the production data request and obtaining the corresponding oilfield production data from the database, thereby improving the security of data acquisition.

[0054] At the same time, in order to ensure the availability of the acquired oilfield production data, an embodiment of the present invention verifies the oilfield production data based on data cleaning technology to confirm whether the oilfield production data meets the availability conditions. The availability conditions include a first condition, a second condition and a third condition. The first condition is that the oilfield production data meets the correctness requirement, the second condition is that the oilfield production data meets the non-duplication requirement, and the third condition is that the oilfield production data meets the integrity requirement. That is, for the availability of the oilfield production data, it is necessary to ensure that the oilfield production data is correct (correctness), non-duplication (singleness) and non-missing (integrity). When the verification result is that the oilfield production data does not meet at least one of the first condition, the second condition and the third condition, the embodiment of the present invention generates and returns a problem report. The problem report is used to send to data maintenance personnel and users to facilitate rapid confirmation of the problem and execution of subsequent production adjustments.

[0055] Among them, confirming that the oilfield production data meets the requirements for correctness means complying with natural and production laws, for example, the liquid production is greater than or equal to the oil production, the block production volume and injection volume are within a preset range, etc.; in some embodiments of the present invention, when the verification result is that the oilfield production data does not meet the first condition and / or the third condition, the embodiment of the present invention can select the historical oilfield production data most recent at the time node of the current oilfield production data as a replacement. If the verification result is that the oilfield production data does not meet the second condition, it can be selected to delete duplicate oilfield production data and generate a problem report.

[0056] S2. generating a layer corresponding to the number of well locations in the well location data according to a user's layer request instruction or preset configuration information and based on the verified oilfield production data;

[0057] The embodiment of the present invention selects a layer generation method based on the user's layer request instruction, and automatically generates a layer corresponding to the number of well locations in the well location data based on the verified oil field production data. In other embodiments of the present invention, one or more layers can also be generated according to the type of well location, or well locations of the same type can be configured in the same layer. The types of well locations include but are not limited to oil wells, water injection wells, shut-down oil wells, shut-down water injection wells, etc.

[0058] Of course, it should be noted that, in other embodiments of the present invention, one or more layers may also be directly generated through preset configuration information (configuration template).

[0059] S3. Generate a corresponding map for each well location based on the verified oilfield production data, wherein the map consists of a well identification symbol, a half pie chart, and a bar chart;

[0060] See Figure 2-3 As shown, it is a reference schematic diagram of the oil well map and the water injection well map in an embodiment of the present invention. The embodiment of the present invention generates a corresponding well identification symbol for each well location based on the oil field production data, and marks the corresponding well location name, and places the well identification symbol at the center of the map; a half pie chart is configured below the well identification symbol, and the setting radius of the half pie chart is positively correlated with the cumulative production in the indicator data; a bar chart is configured above the well identification symbol, and the setting height of the bar chart is positively correlated with the daily production in the indicator data.

[0061] For the half-pie chart, the half-pie chart sectors of oil production wells and shut-in oil production wells represent the cumulative oil and water production, and the setting radius of the half-pie chart is positively correlated with the cumulative liquid production (cumulative oil + cumulative water production); the half-pie chart sectors of water injection wells and shut-in water injection wells represent the cumulative water injection, and the setting radius of the half-pie chart is positively correlated with the cumulative water injection.

[0062] Specifically, in the embodiment of the present invention, the radius of the half pie chart is set Wherein, P is the cumulative fluid production (or cumulative water injection) corresponding to the well location, M is the maximum cumulative fluid production (or cumulative water injection) of all well locations in the mining data, the setting radius r of the half pie chart is in cm, and 2.5 is the adjustment coefficient of the half pie chart. It can be adjusted for the applicability of mining status maps of different scales and screens of different resolutions, and the present invention has no limitation on this.

[0063] For the bar chart, the bar chart of the oil production wells represents the daily liquid production and daily oil production, the bar chart of the water injection wells represents the daily water injection, and the shut-down oil production wells and shut-down water injection wells do not display the bar chart. The height of the bar chart is positively correlated with the daily liquid production, daily oil production or daily water injection volume.

[0064] Specifically, in the embodiment of the present invention, the setting height of the bar graph is Wherein, p is the daily liquid production (or daily water injection) of the well, m is the maximum daily liquid production (or daily water injection) of all wells in the mining data, the setting height h of the bar graph is in cm, and 2.5 is the bar graph adjustment coefficient. It can be adjusted for the applicability of mining status maps of different scales and screens of different resolutions, and the present invention has no limitation on this.

[0065] S4. Add the graphics corresponding to all well locations to the layers respectively, wherein the graphics for each well location are placed in one layer, and confirm whether there is an overlapping area on the display interface for the layers corresponding to all the graphics. For the layers with overlapping areas, move the graphics corresponding to any of the layers in the overlapping area to the blank area of ​​the layer, and draw an indicator line from the well identification symbol to the half pie chart and the bar chart, and finally combine all the layers into a legend.

[0066] See Figure 4-5 As shown, Figure 4 is a reference schematic diagram of overlapping drawings in an embodiment of the present invention, Figure 5 This is a reference schematic diagram after the overlapping of drawings is removed in an embodiment of the present invention;

[0067] Before integrating all layers into a legend, an embodiment of the present invention needs to confirm whether there is an overlapping area on the display interface among the layers corresponding to all the graphics, including separately determining whether all layers on the display interface overlap between half pie charts and half pie charts, between half pie charts and bar charts, and between bar charts and bar charts. The corresponding judgment condition is selected according to the type of overlapping area.

[0068] The display interface is an area on the screen for displaying data, and can be adjusted to suit the required scenario according to the screen resolution and actual application requirements.

[0069] Specifically, the selection of corresponding judgment conditions according to the type of overlapping area includes:

[0070] In an embodiment of the present invention, the middle position of the well identification symbol can be selected as the origin of the coordinate system, or any other fixed point can be selected as the origin of the coordinate system, and the diameter extension direction of the half pie chart (i.e., the horizontal direction) can be used as the x-axis. The relative positions of the left and right endpoints corresponding to the diameter direction of the half pie chart and the left and right endpoints above the bar chart and the origin are determined to obtain the coordinate values ​​of the left and right endpoints corresponding to the diameter direction of the half pie chart and the coordinate values ​​of the left and right endpoints above the bar chart.

[0071] Among them, for the half-pie charts, the left and right endpoint coordinate values ​​corresponding to any two half-pie charts in the diameter direction are determined respectively, and the corresponding areas of the two half-pie charts are calculated. Based on the area size relationship between the two half-pie charts and the difference in the areas corresponding to the two half-pie charts, it is determined whether the two half-pie charts overlap; let the left and right endpoint coordinate values ​​corresponding to the first half-pie chart in the diameter direction be (x1, y1), (x2, y1), let the left and right endpoint coordinate values ​​corresponding to the second half-pie chart in the diameter direction be (x3, y2), (x4, y2), where y1>y2; to improve the calculation efficiency, the half-pie chart can be approximated as an isosceles right triangle, then the areas of the first half-pie chart and the second half-pie chart are respectively and The overlapping part of the half pie chart can also be approximated as an isosceles right triangle. Let Δy=y1-y2, then the hypotenuse length of the overlapping triangle is Δx=max(0,min(x2-Δy,x4)-max(x1+Δy,x3)), and the area of ​​the overlapping part is If S 12 / min(S1, S2)>δ, where δ is a preset parameter, then it is considered that the first half of the pie chart overlaps with the second half of the pie chart, and the preset parameter δ can be determined according to actual needs.

[0072] For the half pie chart and the bar chart, determine the coordinate values ​​of the left and right endpoints of the half pie chart in the diameter direction and the coordinate values ​​of the left and right endpoints above the bar chart respectively, and determine whether the half pie chart and the bar chart overlap based on the relative positions of the left and right endpoints of the half pie chart in the diameter direction and the left and right endpoints above the bar chart; suppose the coordinate values ​​of the left and right endpoints of the half pie chart in the diameter direction are (x1, y1), (x2, y1), and the coordinate values ​​of the left and right endpoints above the bar chart are (x5, y3), (x6, y3). If y1>y3 and min(x2-y1+y3,x5)-max(x1+y1-y3,x6)>0, then it is considered that the half pie chart and the bar chart overlap.

[0073] For the histograms, determine the coordinate values ​​of the lower left endpoint and the upper right endpoint of any two histograms respectively, and determine whether the histograms overlap based on the relative positions of the lower left endpoint and the upper right endpoint of the two histograms; suppose the coordinates of the lower left endpoint and the upper right endpoint of the first histogram are (x5, y1) and (x6, y3) respectively, and the coordinates of the lower left endpoint and the upper right endpoint of the second histogram are (x7, y2) and (x8, y4) respectively. If min(x6, x8) ≥ max(x5, x8) and min(y3, y4) ≥ max(y1, y2), then the first histogram is considered to overlap with the second histogram.

[0074] For the layers with overlapping areas, an embodiment of the present invention automatically moves the graphics corresponding to any of the layers in the overlapping area (or the graphics with the largest area) to the blank area of ​​the layer, and draws an indicator line from the well identification symbol to the half pie chart and the bar chart, or customizes the moving position of the graphics based on the user's graphics movement request. The indicator line can be a dotted line or an indicator line with other guiding functions.

[0075] The method of combining the layers into a legend is to overlay the layers. In other implementations, other combination methods may also be considered.

[0076] The method for generating a legend for an oilfield production status map according to an embodiment of the present invention has the following advantages over the prior art:

[0077] 1. Respond to the user's request for mining data. After selecting the oilfield mining data to be obtained, directly obtain the corresponding oilfield mining data from the corresponding database, which improves the efficiency of data acquisition and reduces system time consumption;

[0078] 2. Generate one or more layers based on the user's layer request instructions, thereby displaying more mining status information, solving the problem of the existing technology that cumulative production and daily production cannot be displayed simultaneously;

[0079] 3. For the occlusion problem between drawings due to unreasonable layout, the system can also automatically identify the overlapping areas between drawings on the display interface and adjust the positions of drawings when overlap is confirmed, solving the problem of difficulty in reading drawings due to drawing occlusion;

[0080] 4. In view of the lack of data information on water injection wells, sealed wells and abandoned wells, the existing maps lack corresponding data. The embodiments of the present invention obtain oil field production data from the database and add it to the map, thereby enriching the well location information and improving the user experience.

The first condition is that the oilfield production data meets the requirement of accuracy, the second condition is that the oilfield production data meets the requirement of no duplication, and the third condition is that the oilfield production data meets the requirement of completeness.

For the layers with overlapping areas, the graphics corresponding to any of the layers in the overlapping area are moved to the blank area of ​​the layer, and indicator lines are drawn from the well identification symbols to the half pie chart and the bar chart, and finally all the layers are combined into a legend.
