[0002] The effective thickness of oil and gas reservoirs refers to the thickness of oil and gas reservoirs that have the capacity to produce oil and gas industrially in the oil and gas-bearing strata that meet the reserve calculation standards under current economic and technical conditions. The standard plate for the lower limit of effective thickness of oil and gas reservoirs is one of the basic maps in the process of reservoir evaluation and reserve declaration, and is of great significance for accurately understanding reservoir characteristics and calculating the effective thickness of oil and gas layers.

[0043] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific embodiments of the present invention are now described in detail with reference to the accompanying drawings. Features defined as "first", "second", "third", etc. may explicitly or implicitly include one or more of the features. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0044] In the following description, specific details such as specific system structures, technologies, etc. are provided for the purpose of illustration rather than limitation, so as to provide a thorough understanding of the embodiments of the present invention. However, it should be clear to those skilled in the art that the present invention may be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to prevent unnecessary details from obstructing the description of the present invention.

[0045] The invention provides a method and device for drawing a standard plate of the lower limit of effective thickness of oil and gas reservoirs, which are used to reduce labor costs.

[0046] The method for drawing the standard plate of the lower limit of the effective thickness of the oil and gas reservoir provided by the present invention is applied to a system, a server or a terminal with logic analysis and processing capabilities for execution and implementation. The embodiment of the present invention is described by taking the system as an example. Figure 1 As shown, an embodiment of the method for drawing the standard plate of the lower limit of effective thickness of oil and gas reservoirs of the present invention comprises:

[0047] S101, extracting target keyword information from raw data, and establishing a standardized format basic data table according to the target keyword information, wherein the raw data is basic data for establishing a standard for the lower limit of effective thickness of oil and gas reservoirs;

[0048] In this embodiment, the system first obtains the original data uploaded by the user. The original data contains wellbore measurement data, reservoir parameter logging calculation data, pressure measurement data, sampling data, geological stratification data, coring data, and oil and gas well mid-test and production data, etc., which are basic data data for establishing the lower limit standard of effective thickness of oil and gas reservoirs. Among them, the wellbore measurement data may include parameters such as natural gamma, density, neutron porosity, acoustic wave time difference and resistivity, and the reservoir parameter logging calculation data may include parameters such as porosity, permeability and saturation.

[0049] Then, the system extracts the target keyword information corresponding to the target keyword from the original data according to the preset target keyword. For example, the target keyword can be preset as the well name, layer name, data source, depth, porosity, mud content, water saturation, resistivity and conclusion description. The target keyword information is the data corresponding to each target keyword, such as the well name is XJ2-4-A and the layer name is ZJ110. The specific information is not limited here. Finally, the target keyword information corresponding to all basic data points is sorted and summarized to obtain a standardized format basic data table. For example, the standardized format basic data table corresponding to the above target keyword example is as follows:

[0050]

[0051] S102, classifying all basic data points in the standardized format basic data table according to the target keyword information to obtain several different types of basic data point sets;

[0052] In this embodiment, in the standard plate of the lower limit of the effective thickness of the oil and gas reservoir, it is usually required that the basic data points of the same type should have the same display form, so it is necessary to classify the basic data points. Among them, the target keyword information contains data corresponding to multiple target keywords. When a certain target keyword is used as a reference, the system can classify each basic data point in the standardized format basic data table according to the reference. For example: taking the data source and conclusion description in the target keyword as a reference, when the data source and conclusion description between any different basic data points are the same, these basic data points can be divided into the same type, and the specific classification process will be described in the subsequent embodiments. After the classification is completed, different types of basic data point sets can be obtained, and the basic data point set contains multiple different types of basic data points, such as: type A basic data point, type B basic data point or type C basic data point. Each type of basic data point can contain only one basic data point or contain multiple basic data points at the same time, which is not limited here.

[0053] S103, importing different types of basic data point sets into the initial template in sequence;

[0054] In this embodiment, the initial template is a preliminarily established two-dimensional scattered point intersection plate, which is a blank plate with no data. Users can establish blank plates of different styles as initial templates according to actual needs, so that the system can quickly import different types of basic data point sets in sequence.

[0055] S104, setting corresponding display forms for all different types of basic data point sets in the initial template according to preset distinction rules to generate a standard plate for the lower limit of effective thickness of oil and gas reservoirs.

[0056] After all different types of basic data point sets are imported into the initial template, in order to facilitate the distinction between the basic data point sets in the initial template, different display forms can be set for different types of basic data point sets according to preset distinction rules to generate a more intuitive standard plate for the lower limit of effective thickness of oil and gas reservoirs.

[0057] In this embodiment, firstly, the target keyword information is extracted from the original data, and a standardized format basic data table is established according to the target keyword information. The original data data is the basic data data used to establish the standard of the lower limit of the effective thickness of the oil and gas reservoir; then, all the basic data points in the standardized format basic data table are classified and processed according to the target keyword information to obtain several different types of basic data point sets; then, the different types of basic data point sets are sequentially imported into the initial template; finally, all different types of basic data point sets in the initial template are set to the corresponding display form according to the preset distinction rules to generate the standard plate of the lower limit of the effective thickness of the oil and gas reservoir. In this way, each basic data point can be classified and processed according to the target keyword information, and then the basic data points imported into the initial template are displayed and distinguished according to different types and preset distinction rules, so as to realize the drawing of the standard plate of the lower limit of the effective thickness of the oil and gas reservoir, and no longer need to be classified and displayed manually, so as to reduce the labor cost of drawing the standard plate of the lower limit of the effective thickness of the oil and gas reservoir. In addition, since it is no longer necessary to classify and display manually, the working time increased by manual operation can be reduced to improve the drawing efficiency of the standard plate of the lower limit of the effective thickness of the oil and gas reservoir. Moreover, since preset distinction rules are used for display distinction, the differences between plates drawn by different staff members can be reduced, thereby improving the comparability and universality between different plates.

[0058] like Figure 2 As shown, another embodiment of the method for drawing the standard plate of the lower limit of effective thickness of oil and gas reservoirs of the present invention comprises:

[0059] S201, extracting target keyword information from raw data, and establishing a standardized format basic data table according to the target keyword information, wherein the raw data is basic data for establishing a standard for the lower limit of effective thickness of oil and gas reservoirs;

[0060] Step S201 in this embodiment is similar to the above Figure 1 The type of step S101 in the illustrated embodiment will not be described in detail here.

[0061] S202, assigning a label in a unified format to each basic data point in the standardized format basic data table, the label including four target keyword information: well name, layer name, data source, and conclusion description, the well name and layer name are composed of a number of different codes, the different codes in the well name are used to determine whether different basic data points belong to the same geological structural unit in the plane, and the different codes in the layer name are used to determine whether different basic data points belong to the same stratigraphic unit in the vertical direction;

[0062] S203, determining whether different basic data points simultaneously meet the first preset classification condition, the second preset classification condition, and the third preset classification condition, wherein the first preset classification condition is that the data sources and conclusion descriptions in the labels corresponding to different basic data points are consistent, the second preset classification condition is that the different basic data points belong to the same geological structural unit in the plane, and the third preset classification condition is that the different basic data points belong to the same stratigraphic unit in the vertical direction. If so, executing step S204;

[0063] S204, determining that different basic data points are basic data points of the same type;

[0064] Optionally, in this embodiment, before classifying each basic data point, a label in a unified format can be assigned to each basic data point to facilitate the system's identification during the classification process, and the label can also be used as the type name of different types. The label can be composed of data corresponding to four target keywords: well name, layer name, data source, and conclusion description. For example: the label of basic data point A is the pressure measurement oil layer point of the MN567 layer of the XY1-2-3 well.

[0065] Specifically, the well name can be composed of several different codes, such as: the well name of basic data point B is XY1-2-3 well, which is composed of four codes in sequence, among which "XY" is the depression code, "1" is the block code, "2" is the trap code, and "3" is the well point code. For different application scenarios of the standard plate of the lower limit of effective thickness of oil and gas reservoirs, the same geological structure unit can be set as the same well point, trap, block or depression and other well name code units. For different geological structural units, the second preset classification condition will have different definitions. For example, if the well point is selected as the basic geological structural unit on the plane, it can be determined that different basic data points with completely identical four codes in the well name belong to the same geological structural unit on the plane, and different basic data points with completely identical four codes in the well name can be classified into one category during the classification process; if the trap is selected as the basic geological structural unit on the plane, it can be determined that different basic data points with completely identical first three codes in the well name belong to the same geological structural unit on the plane, and different basic data points with completely identical first three codes in the well name can be classified into one category during the classification process. The basic data points with exactly the same codes in the first two items of the well name can be classified into one category; if the block is selected as the basic geological structural unit on the plane, it can be determined that the different basic data points with exactly the same codes in the first two items of the well name belong to the same geological structural unit on the plane, and the different basic data points with exactly the same codes in the first two items of the well name can be classified into one category during the classification process; if the depression is selected as the basic geological structural unit on the plane, it can be determined that the different basic data points with exactly the same codes in the first item of the well name belong to the same geological structural unit on the plane, and the different basic data points with exactly the same codes in the first item of the well name can be classified into one category during the classification process.

[0066] The layer name can be composed of several different codes. For example, the layer name of the basic data point C is MN567 layer, which is composed of 4 codes in sequence, among which "MN" is the group code, "5" is the segment code, "6" is the stratum code, and "7" is the sublayer code. For different application scenarios of the standard plate of the lower limit of effective thickness of oil and gas reservoirs, the same stratigraphic unit can be set as the same sublayer, stratigraphic system, segment or group and other stratigraphic name code units. For different stratigraphic unit compositions, the third preset classification condition will have different definitions. For example, if the sublayer is selected as the basic stratigraphic unit in the vertical direction, different basic data points with exactly the same four codes in the layer name can be determined to belong to the same stratigraphic unit in the vertical direction, and different basic data points with exactly the same four codes in the layer name can be classified into one category during the classification process; if the layer system is selected as the basic stratigraphic unit in the vertical direction, different basic data points with exactly the same first three codes in the layer name can be determined to belong to the same stratigraphic unit in the vertical direction, and the first three codes in the layer name can be classified into one category during the classification process. Different basic data points that are completely consistent are grouped into one category; if the segment is selected as the basic stratigraphic unit in the vertical direction, it can be determined that different basic data points with the first two items of the stratigraphic name are completely consistent belong to the same stratigraphic unit in the vertical direction, and different basic data points with the first two items of the stratigraphic name are completely consistent can be grouped into one category in the classification process; if the group is selected as the basic stratigraphic unit in the vertical direction, it can be determined that different basic data points with the first item of the stratigraphic name are completely consistent belong to the same stratigraphic unit in the vertical direction, and different basic data points with the first item of the stratigraphic name are completely consistent can be grouped into one category in the classification process.

[0067] During the classification process, different basic data points that simultaneously meet the first preset classification condition, the second preset classification condition and the third preset classification condition can be classified into the same type. For example, the basic data point types can be divided into 5 categories, namely, "XJ2-4 trap ZJ group pressure measurement water layer point", "XJ2-4 trap ZJ group pressure measurement oil layer point", "XJ2-4 trap ZJ group sampling oil layer point", "XJ2-4 trap ZJ group sampling water layer point" and "XJ2-4 trap ZJ group pressure measurement dry layer point".

[0068] S205, importing different types of basic data point sets into the initial template in sequence;

[0069] Step S205 in this embodiment is similar to the above Figure 1 Step S103 in the illustrated embodiment is similar and will not be described in detail here.

[0070] S206, assigning blue values ​​to the basic data point set whose conclusion description type is water layer, assigning black values ​​to the basic data point set whose conclusion description type is dry layer, and assigning mixed color values ​​to the basic data point set whose conclusion description type is other layers, wherein the mixed color values ​​include red, yellow, green and purple. The conclusion description type includes water layer, dry layer and other layers, and the other layers include background points of non-target areas. The background points of the non-target areas are the conclusion description types corresponding to the basic data points that do not belong to the same geological structural unit in the plane and do not belong to the same stratigraphic unit in the vertical direction.

[0071] Optionally, in this embodiment, different types of basic data point sets can be color-differentiated according to different conclusion description types, where the conclusion description types may include water layers, dry layers, and other layers, and other layers may include oil layers, oil-water layers, oil-water layers, and gas layers, which are not specifically limited here.

[0072] Specifically, when configuring colors, six color systems can be set, including blue, black, red, yellow, green and purple. The red, yellow, green and purple systems are called mixed color systems, and each color system is divided into multiple colors according to the chromaticity distinction. Among them, when the conclusion description type of any basic data point set is a water layer, all basic data points in the basic data point set are set in a blue system; when the conclusion description type of any basic data point set is a dry layer, all basic data points in the basic data point set are set in a black system; when the conclusion description type of any basic data point set is an oil layer, an oil-water layer, an oil-water layer or a gas layer and other layers, all basic data points in the basic data point set are set in a mixed color system. In this way, different types of color distinction settings can be used to improve the recognition of basic data points, making the standard plate of the lower limit of effective thickness of oil and gas reservoirs more intuitive.

[0073] S207, assigning core customized symbols to the basic data point set whose data source type is core; assigning conventional symbols to the basic data point set whose data source type is non-core, and the data source type includes core and non-core;

[0074] Optionally, in this embodiment, different types of basic data point sets can be differentiated in shape according to different data source types, where the data source types include core and non-core, and non-core can include mid-stream testing, pressure measurement, sampling and production of oil and gas wells, which are not specifically limited here.

[0075] Specifically, when configuring symbols, two major types of symbols can be set, including core customized symbol types and conventional symbol types. Among them, core customized symbol types include symbols such as oil-saturated, oil-rich, oil-immersed, oil spots, oil traces, fluorescence and no display, and conventional symbol types include symbols such as circles, squares, diamonds, five-pointed stars, regular triangles, inverted triangles, crosses, forks, horizontal lines and vertical lines. When the data source type of any basic data point set is core, the shapes of all basic data points in the basic data point set are set to core customized symbols; when the data source type of any basic data point set is non-core, the shapes of all basic data points in the basic data point set are set to conventional symbols. In this way, different types of shapes can be used to distinguish and set them, which further improves the recognition of basic data points and makes the standard plate of the lower limit of effective thickness of oil and gas reservoirs more intuitive.

[0076] S208, when the conclusion description type of the basic data point set is a dry layer, eliminating the internal filling color of the symbol corresponding to the basic data point set;

[0077] S209: When the conclusion description type of the basic data point set is a background point of a non-target area, the size and color transparency of the corresponding symbol of the basic data point set are reduced by half.

[0078] Optionally, in this embodiment, other layers in the conclusion description type may also include background points of non-target areas, and the background points of non-target areas and the dry layer both belong to special conclusion description types, so the basic data point sets of these two types can be specially displayed to distinguish. Specifically, when the conclusion description type of the basic data point set is the dry layer, the internal fill color of the corresponding symbol of the basic data point set is eliminated, and only the symbol border of its black color is retained; when the conclusion description type of the basic data point set is the background points of the non-target area, the symbol size of the corresponding symbol of the basic data point set is reduced to half of the original, and the corresponding color transparency is reduced to half of the original. In this way, the distinction between special types of basic data points and other basic data points can be improved, making all basic data points easier to identify.

[0080] The establishing unit 301 is used to extract target keyword information from the original data, and establish a standardized format basic data table according to the target keyword information, wherein the original data is the basic data data used to establish the lower limit standard of the effective thickness of the oil and gas reservoir;
