Description

Technical Field

[0001] The present invention relates to the technical field of geological research, and particularly to a method, device, equipment and medium for determining a structural trap volume correction coefficient. Background Art

[0002] The structural trap volume is a direct parameter for predicting the potential of oil and gas resources stored in a structural trap. Generally, the structural trap volume is calculated by the product of the bottom area and the reservoir thickness. However, there is a large error between the structural trap volume determined in this way and the actual situation. Usually, a volume correction coefficient is introduced to correct the calculated structural trap volume. Therefore, how to accurately obtain the volume correction coefficient of the structural trap has become the biggest bottleneck restricting the prediction accuracy of the structural trap resource volume.

[0003] In the prior art, usually, the volume correction coefficient of the structural trap is directly assigned based on personal experience or by using the expert scoring method during the prediction of the structural trap resource volume, or even the influence of this parameter on the resource volume prediction result is directly ignored. The structural trap resource volume obtained thereby usually overestimates or underestimates the structural trap volume, and the result has an obvious error. Therefore, it cannot truly reflect the real resource potential underground, and directly affects the evaluation of the exploration potential of the structural trap and the deployment of the exploration plan.

[0037] Embodiment 1

[0038] Figure 1 It is a flowchart of a method for determining the structural trap volume correction coefficient provided in Embodiment 1 of the present invention. This embodiment is applicable to the situation of quickly and accurately obtaining the structural trap volume correction coefficient. This method can be executed by a device for determining the structural trap volume correction coefficient, and the device for determining the structural trap volume correction coefficient can be implemented in the form of hardware and / or software. The device for determining the structural trap volume correction coefficient can be configured in an electronic device with data processing capabilities. As Figure 1 shown, the method includes:

[0039] S110, determine the trap type of the to-be-detected structural trap, and determine the standard cross-section of the to-be-detected structural trap according to the trap type; the trap type includes anticline type, fault-anticline type, and fault-block type, and the standard cross-section is used to represent the plane where the bottom surface of the to-be-detected structural trap is located.

[0040] Among them, a structural trap may refer to a trap formed by a reservoir rock formation and its overlying caprock due to a certain local structural deformation. The structural trap to be measured may refer to a structural trap waiting to be detected. The trap type can be used to characterize the type of the structural trap, specifically including three types: anticline type, fault-anticline type, and fault-block type. A standard cross-section may refer to a representative cross-section selected to determine the volume correction coefficient of the structural trap to be measured, and can be used to represent the plane where the bottom surface of the structural trap to be measured is located. It should be noted that the selection of the standard cross-section is related to the trap type of the structural trap to be measured. Since the structural traps to be measured with different trap types have different structural characteristics, different representative standard cross-sections need to be selected correspondingly.

[0041] In this embodiment, first, the trap type of the structural trap to be measured is determined, and then the standard cross-section of the structural trap to be measured is determined according to the trap type. Optionally, the standard cross-section is determined according to the cross-section where the target line segment within the range of the structural trap to be measured is located, where: when the trap type is anticline type, the target line segment is the line segment passing through the center point of the anticline within the range of the structural trap to be measured, and the length of the target line segment is equal to the average length of the first reference line segment and the second reference line segment. The first reference line segment and the second reference line segment are respectively the longest line segment and the shortest line segment passing through the center point of the anticline within the range of the structural trap to be measured; when the trap type is fault-anticline type, the target line segment is the line segment perpendicular to the fault controlling the trap within the range of the structural trap to be measured, and the length of the target line segment is equal to half of the length of the third reference line segment. The third reference line segment is the longest line segment perpendicular to the fault controlling the trap within the range of the structural trap to be measured; when the trap type is fault-block type, the target line segment is the line segment parallel to the fourth reference line segment within the range of the fault-block type trap to be measured, and the length of the target line segment is equal to half of the length of the fourth reference line segment. The fourth reference line segment is the connection line of the intersection points of the two faults controlling the trap and the structural spill point isoline within the range of the fault-block type trap to be measured.

[0042] Among them, the target line segment can be used as the direct basis for selecting the standard cross-section. Specifically, the standard cross-section is determined according to the cross-section where the target line segment within the range of the structural trap to be measured is located. Figure 2A It is a schematic diagram of a standard cross-section of an anticline type structural trap provided in Embodiment 1 of the present invention. As Figure 2A shown in the left figure in ′ aa ′ represents the target line segment, bb ′ represents the longest line segment (i.e., the first reference line segment) passing through the center point of the anticline within the range of the anticline type structural trap, cc ′ represents the shortest line segment (i.e., the second reference line segment) passing through the center point of the anticline within the range of the anticline type structural trap. Among them, aa ′ passes through the center point of the anticline within the range of the anticline type structural trap, and the length of aa ′ is equal to the average length of bb ′ and cc ′ . AsFigure 2A As shown in the right figure in r L r and H ′ respectively represent the reservoir cross-sectional length and the reservoir cross-sectional thickness within the anticlinal trap range on the standard cross-section at the ideal angle, where the ideal angle means the reservoir dip angle is 0 degrees. It should be noted that the position of the target line segment aa r is the mean position reflecting the influence of L

Figure 2B As shown in the left figure in ′ aa ′ represents the target line segment, and bb ′ represents the longest line segment (i.e., the third reference line segment) perpendicular to the trap-control fault within the range of the faulted anticlinal structural trap. Among them, aa ′ is perpendicular to the trap-control fault within the range of the faulted anticlinal structural trap, and the length of aa ′ is equal to half of the length of bb Figure 2B As shown in the right figure in r L r and H ′ respectively represent the reservoir cross-sectional length and the reservoir cross-sectional thickness within the faulted anticlinal trap range on the standard cross-section at the ideal angle. It should be noted that the position of the target line segment aa r is the mean position reflecting the influence of L

[0044] Figure 2C This is a schematic diagram of the standard cross-section of a fault-block type structural trap provided in the first embodiment of the present invention. As Figure 2C shown in the left figure in ′ aa ′ represents the target line segment, and bb ′ represents the connection line (i.e., the fourth reference line segment) of the intersection points of the two trap-control faults within the range of the fault-block trap and the structural spill point isoline. Among them, aa ′ is parallel to bb ′ and the length of aa ′ is equal to half of the length of bb Figure 2C As shown in the right figure in r L r and H ′ respectively represent the reservoir cross-sectional length and the reservoir cross-sectional thickness within the fault-block trap range on the standard cross-section at the ideal angle. It should be noted that the position of the target line segment aa rThe mean position affecting the bottom area of the fault-block type structural trap, so the selected standard cross-section is representative.

[0045] S120, determine the target parameter information of the to-be-detected structural trap on the standard cross-section, and determine the reference correction coefficient of the to-be-detected structural trap according to the target parameter information; the reference correction coefficient includes at least two of the amplitude correction coefficient, the fault correction coefficient, and the reservoir correction coefficient.

[0046] Among them, the target parameter information can be used as the basis for determining the reference correction coefficient of the to-be-detected structural trap and needs to match the trap type, that is, different trap types correspond to different target parameter information. The reference correction coefficient can be used as the basis for determining the volume correction coefficient of the to-be-detected structural trap and also needs to match the trap type, that is, different trap types correspond to different reference correction coefficients. Among them, the reference correction coefficient includes at least two of the amplitude correction coefficient, the fault correction coefficient, and the reservoir correction coefficient. Exemplarily, when the trap type is the anticline type, the reference correction coefficient includes two types: the amplitude correction coefficient and the reservoir correction coefficient; when the trap type is the fault-anticline type, the reference correction coefficient includes three types: the amplitude correction coefficient, the fault correction coefficient, and the reservoir correction coefficient; when the trap type is the fault-block type, the reference correction coefficient includes two types: the fault correction coefficient and the reservoir correction coefficient.

[0047] Among them, the amplitude correction coefficient is determined according to the ratio of the first cross-sectional area to the second cross-sectional area. The first cross-sectional area is determined based on the first reference area, and the first reference area refers to the cross-sectional area of the to-be-detected structural trap affected by the top surface amplitude. The second cross-sectional area is determined based on the second reference area, and the second reference area refers to the cross-sectional area of the to-be-detected structural trap at the ideal angle. The ideal angle means that the reservoir dip angle is 0 degrees. The fault correction coefficient is determined according to the ratio of the third cross-sectional area to the second cross-sectional area. The third cross-sectional area is determined based on the third reference area, and the third reference area refers to the cross-sectional area of the to-be-detected structural trap affected by the controlled fault. The reservoir correction coefficient is determined according to the ratio of the fourth cross-sectional area to the second cross-sectional area. The fourth cross-sectional area is determined based on the fourth reference area, and the fourth reference area refers to the cross-sectional area of the to-be-detected structural trap affected by the reservoir attitude inclination.

[0048] In this embodiment, after determining the corresponding standard cross-section according to the trap type of the to-be-detected structural trap, it is necessary to further determine the target parameter information of the to-be-detected structural trap on the standard cross-section and determine the reference correction coefficient of the to-be-detected structural trap according to the target parameter information.

[0049] In this embodiment, optionally, determining a reference correction coefficient for a to-be-detected structural trap according to target parameter information includes: when the trap type is an anticline type, determining an amplitude correction coefficient for the to-be-detected structural trap according to the first amplitude parameter information and the first amplitude function in the target parameter information; wherein, the first amplitude parameter information includes the reservoir cross-sectional length and the reservoir cross-sectional thickness within the range of the to-be-detected structural trap on the standard cross-section at the ideal angle, and the left-wing top surface dip angle and the right-wing top surface dip angle of the to-be-detected structural trap on the standard cross-section; the first amplitude function is used to describe the mapping relationship between the first amplitude parameter information and the amplitude correction coefficient; when the trap type is a fault-anticline type, determining an amplitude correction coefficient for the to-be-detected structural trap according to the second amplitude parameter information and the second amplitude function in the target parameter information; wherein, the second amplitude parameter information includes the reservoir cross-sectional length and the reservoir cross-sectional thickness within the range of the to-be-detected structural trap on the standard cross-section at the ideal angle, and the top surface dip angle of the to-be-detected structural trap on the standard cross-section; the second amplitude function is used to describe the mapping relationship between the second amplitude parameter information and the amplitude correction coefficient.

[0050] Among them, the first amplitude parameter information may refer to the parameter information associated with determining the amplitude correction coefficient in the target parameter information of the anticline-type structural trap. Among them, the first amplitude parameter information includes the reservoir cross-sectional length and the reservoir cross-sectional thickness within the range of the to-be-detected structural trap on the standard cross-section at the ideal angle, and the left-wing top surface dip angle and the right-wing top surface dip angle of the to-be-detected structural trap on the standard cross-section. The first amplitude function may refer to the preset functional relationship for determining the amplitude correction coefficient of the anticline-type structural trap, and can be used to describe the mapping relationship between the first amplitude parameter information and the amplitude correction coefficient. Exemplarily, the first amplitude function can be set as C = H r (cotα1 + cotα r ) / 2L r , where C is the amplitude correction coefficient, L r and H r are respectively the reservoir cross-sectional length and the reservoir cross-sectional thickness within the range of the anticline-type trap on the standard cross-section at the ideal angle, and α1 and α r are respectively the left-wing top surface dip angle and the right-wing top surface dip angle of the anticline-type trap on the standard cross-section.

[0051] Specifically, as shown in the right figure of Figure 2A , the cross-sectional area (i.e., the second cross-sectional area) of the anticline-type structural trap at the ideal angle can be expressed as L r × H r . Figure 3A is a schematic diagram of the first cross-sectional area of an anticline-type structural trap provided in the first embodiment of the present invention. Among them, the first cross-sectional area can be used to characterize the cross-sectional area of the anticline-type structural trap affected by the top surface amplitude. As shown in Figure 3A , the first cross-sectional area can be expressed as 1 / 2 × Hr ×H r ×(cotα1 + cotα r )。Therefore, the first amplitude function can be expressed as C = 1 / 2 × H r ×H r ×(cotα1 + cotα r ) / (L r ×H r ) = H r (cotα1 + cotα r ) / 2L r 。Furthermore, when α1 = α r = α, the first amplitude function can be expressed as C = H r cotα / L r 。For an anticlinal structural trap, after obtaining the target parameter information, the first amplitude parameter information in the target parameter information can be substituted into the first amplitude function, and the amplitude correction coefficient of the anticlinal structural trap can be obtained through calculation.

[0052] Among them, the second amplitude parameter information can refer to the parameter information associated with determining the amplitude correction coefficient in the target parameter information of a fault-anticlinal structural trap. Among them, the second amplitude parameter information includes the length and thickness of the reservoir cross-section within the range of the structural trap to be measured on the standard cross-section at the ideal angle, and the dip angle of the top surface of the structural trap to be measured on the standard cross-section. The second amplitude function can refer to the functional relationship for presetting the amplitude correction coefficient of a fault-anticlinal structural trap, which can be used to describe the mapping relationship between the second amplitude parameter information and the amplitude correction coefficient. It should be noted that the second amplitude function and the first amplitude function can be set to the same functional form or different functional forms, which can be specifically set according to actual needs.

[0053] Exemplarily, if the second amplitude function and the first amplitude function have the same functional form, such as setting the second amplitude function to C = H r (cotα1 + cotα r ) / 2L r , where L r and H r respectively represent the length and thickness of the reservoir cross-section within the range of the fault-anticlinal trap on the standard cross-section at the ideal angle, α1 represents the dip angle of the top surface of the fault-anticlinal trap on the standard cross-section, and at this time α r does not exist (this item is ignored). If the second amplitude function and the first amplitude function have different functional forms, the second amplitude function can be directly set to C = H r cotα / 2L r , where α represents the dip angle of the top surface of the fault-anticlinal trap on the standard cross-section. Specifically, such as Figure 2BAs shown in the middle right figure, the cross-sectional area (i.e., the second cross-sectional area) of the faulted anticline type structural trap at the ideal angle can be expressed as L r ×H r . Figure 3B This is a schematic diagram of the first cross-sectional area of a faulted anticline type structural trap provided in the first embodiment of the present invention. Among them, the first cross-sectional area is used to characterize the cross-sectional area of the faulted anticline type structural trap caused by the influence of the top surface amplitude. As Figure 3B shown, the first cross-sectional area can be expressed as 1 / 2×H r ×H r ×cotα. Therefore, the second amplitude function can be expressed as C = 1 / 2×H r ×H r ×cotα / (L r ×H r ) = H r cotα / 2L r . For the faulted anticline type structural trap, after obtaining the target parameter information, the second amplitude parameter information in the target parameter information can be substituted into the second amplitude function, and the amplitude correction coefficient of the faulted anticline type structural trap can be obtained through calculation.

[0054] It should be noted that when the trap type is the fault block type, neither α1 nor α r exists. At this time, there is no need to consider the amplitude correction coefficient, so the amplitude correction coefficient of the fault block type structural trap can be directly set to 0. Thus, a general amplitude function can be set to solve the amplitude correction coefficients of the three types of structural traps respectively.

[0055] In this embodiment, optionally, determining the reference correction coefficient of the to-be-detected structural trap according to the target parameter information includes: when the trap type is the faulted anticline type, determining the fault correction coefficient of the to-be-detected structural trap according to the first fault parameter information and the first fault function in the target parameter information; wherein, the first fault parameter information includes the reservoir cross-sectional length and the reservoir cross-sectional thickness within the range of the to-be-detected structural trap on the standard cross-section at the ideal angle, and the controlled trap fault dip angle of the to-be-detected structural trap on the standard cross-section; the first fault function is used to describe the mapping relationship between the first fault parameter information and the fault correction coefficient; when the trap type is the fault block type, determining the fault correction coefficient of the to-be-detected structural trap according to the second fault parameter information and the second fault function in the target parameter information; wherein, the second fault parameter information includes the reservoir cross-sectional length and the reservoir cross-sectional thickness within the range of the to-be-detected structural trap on the standard cross-section at the ideal angle, and the left-wing controlled trap fault dip angle and the right-wing controlled trap fault dip angle of the to-be-detected structural trap on the standard cross-section; the second fault function is used to describe the mapping relationship between the second fault parameter information and the fault correction coefficient.

[0056] Among them, the first fault parameter information may refer to the parameter information related to determining the fault correction coefficient in the target parameter information of the fault-anticline type structural trap. Among them, the first fault parameter information includes the length and thickness of the reservoir cross-section within the range of the to-be-detected structural trap on the standard cross-section at the ideal angle, and the dip angle of the trap-controlling fault of the to-be-detected structural trap on the standard cross-section. The first fault function may refer to the functional relationship for presetting the fault correction coefficient of the fault-anticline type structural trap, which can be used to describe the mapping relationship between the first fault parameter information and the fault correction coefficient. Exemplarily, the first fault function can be set as F = H r tanβ / 2L r , where F represents the fault correction coefficient, L r and H r are respectively the length and thickness of the reservoir cross-section within the range of the fault-anticline type trap on the standard cross-section at the ideal angle, and β is the dip angle of the trap-controlling fault of the fault-anticline type trap on the standard cross-section.

[0057] Specifically, as shown in the right figure of Figure 2B , the cross-sectional area (i.e., the second cross-sectional area) of the fault-anticline type structural trap at the ideal angle can be expressed as L r × H r . Figure 4A This is a schematic diagram of the third cross-sectional area of a fault-anticline type structural trap provided in the first embodiment of the present invention. Among them, the third cross-sectional area can be used to characterize the cross-sectional area of the fault-anticline type structural trap affected by the trap-controlling fault. As shown in Figure 4A , the third cross-sectional area can be expressed as 1 / 2 × H r × H r × tanβ. Therefore, the first fault function can be expressed as F = 1 / 2 × H r × H r × tanβ / (L r × H r ) = H r tanβ / 2L r . For the fault-anticline type structural trap, after obtaining the target parameter information, the first fault parameter information in the target parameter information can be substituted into the first fault function, and the fault correction coefficient of the fault-anticline type structural trap can be obtained through calculation.

[0058] Among them, the second fault parameter information may refer to the parameter information related to determining the fault correction coefficient in the target parameter information of the fault-block type structural trap. Among them, the second fault parameter information includes the reservoir cross-sectional length and the reservoir cross-sectional thickness within the range of the to-be-detected structural trap on the standard cross-section at the ideal angle, as well as the left-wing trap-controlling fault dip angle and the right-wing trap-controlling fault dip angle of the to-be-detected structural trap on the standard cross-section. The second fault function may refer to the function relationship for presetting the fault correction coefficient of the fault-block type structural trap, which can be used to describe the mapping relationship between the second fault parameter information and the fault correction coefficient. Exemplarily, the second fault function may be set as F = H r (tanβ1 + tanβ r ) / 2L r , where L r and H r respectively represent the reservoir cross-sectional length and the reservoir cross-sectional thickness within the range of the fault-block type trap on the standard cross-section at the ideal angle, and β1 and β r respectively represent the left-wing trap-controlling fault dip angle and the right-wing trap-controlling fault dip angle of the fault-block type trap on the standard cross-section.

[0059] Specifically, as shown in the right figure of Figure 2C , the cross-sectional area (i.e., the second cross-sectional area) of the fault-block type structural trap at the ideal angle can be expressed as L r × H r . Figure 4B This is a schematic diagram of the third cross-sectional area of a fault-block type structural trap provided in Embodiment 1 of the present invention. Among them, the third cross-sectional area can be used to characterize the cross-sectional area of the fault-block type structural trap affected by the trap-controlling fault. As shown in Figure 4B , the third cross-sectional area can be expressed as 1 / 2 × H r × H r × (tanβ1 + tanβ r ). Therefore, the second fault function can be expressed as F = 1 / 2 × H r × H r × (tanβ1 + tanβ r ) / (L r × H r ) = H r (tanβ1 + tanβ r ) / 2L r . Further, when β1 = β r = β, the second fault function can be expressed as F = H r tanβ / L r . For the fault-block type structural trap, after obtaining the target parameter information, the second fault parameter information in the target parameter information can be substituted into the second fault function, and the fault correction coefficient of the fault-block type structural trap can be obtained through calculation.

[0060] It should be noted that the first fault function and the second fault function can be set to the same function form or different function forms, which can be specifically set according to actual needs. If the first fault function and the second fault function have the same function form, for example, both are set to F = H r (tanβ1 + tanβ r ) / 2L r . For fault-block type structural traps, β1 and β r respectively represent the dip angles of the left-wing trap-controlling fault and the right-wing trap-controlling fault of the fault-block type trap in the standard cross-section; for fault-anticline type structural traps, β1 represents the dip angle of the trap-controlling fault of the fault-anticline type trap in the standard cross-section, and at this time β r does not exist (this item is ignored). For anticline type structural traps, both β1 and β r do not exist. At this time, the fault correction coefficient does not need to be considered, so the fault correction coefficient of the anticline type structural trap can be directly set to 0. Thus, a general fault function can be set to solve the fault correction coefficients of the three types of structural traps respectively.

[0061] In this embodiment, optionally, determining the reference correction coefficient of the to-be-detected structural trap according to the target parameter information includes: determining the reservoir correction coefficient of the to-be-detected structural trap according to the reservoir parameter information in the target parameter information and the preset reservoir function; wherein, the reservoir parameter information includes the reservoir dip angle in the to-be-detected structural trap, and the preset reservoir function is used to describe the mapping relationship between the reservoir parameter information and the reservoir correction coefficient.

[0062] Among them, the reservoir parameter information may refer to the parameter information in the target parameter information of the to-be-detected structural trap that is associated with determining the reservoir correction coefficient. Among them, the reservoir parameter information includes the reservoir dip angle in the to-be-detected structural trap. The preset reservoir function may refer to the function relationship for determining the reservoir correction coefficient of the to-be-detected structural trap preset in advance, which can be used to describe the mapping relationship between the reservoir parameter information and the reservoir correction coefficient. Exemplarily, the preset reservoir function can be set to R = 1 / cosγ - 1, where R represents the reservoir correction coefficient and γ represents the reservoir dip angle in the to-be-detected structural trap.

[0063] Specifically, as shown in the right figure of Figures 2A - 2C , the cross-sectional area (i.e., the second cross-sectional area) of the to-be-detected structural trap at the ideal angle can be expressed as L r ×H r , where L r and H r respectively represent the reservoir cross-sectional length and the reservoir cross-sectional thickness within the range of the to-be-detected trap in the standard cross-section at the ideal angle. Figure 5 This is a schematic diagram of the fourth cross-sectional area of a to-be-detected structural trap provided in Embodiment 1 of the present invention.

[0064] Among them, the ideal state refers to the state at an ideal angle, and the fourth cross-sectional area can be used to characterize the cross-sectional area of the trap of the structure to be measured caused by the inclination of the reservoir attitude. For example Figure 5 As shown, the fourth cross-sectional area can be expressed as L rt ×(H r -L r )×H r =L r / cosγ×H r -L r ×H r =L r ×H r ×(1 / cosγ - 1), where L rt is the true reservoir cross-sectional length within the range of the trap of the structure to be measured caused by the inclination of the reservoir attitude. Therefore, the preset reservoir function can be expressed as R = L r ×H r ×(1 / cosγ - 1) / (L r ×H r ) = 1 / cosγ - 1. Through this general preset reservoir function, the fault correction coefficients of the three types of traps can be solved respectively.

[0065] S130, determine the volume correction coefficient of the trap of the structure to be measured according to the reference correction coefficient.

[0066] In this embodiment, after determining the reference correction coefficient of the trap of the structure to be measured, the volume correction coefficient of the trap of the structure to be measured can be further determined according to the reference correction coefficient. Exemplarily, a general formula for obtaining the volume correction coefficient can be set, such as V FA =1 - C - F + R, and the volume correction coefficients of the three types of traps to be measured are determined respectively. Among them, V FA is the volume correction coefficient of the trap of the structure to be measured, and C, F, and R are the amplitude correction coefficient, fault correction coefficient, and reservoir correction coefficient of the trap of the structure to be measured respectively. Specifically, for the anticline-type trap, the fault correction coefficient does not need to be considered, so F = 0 can be set, that is, V FA =1 - C + R; for the fault-block type trap, the amplitude correction coefficient does not need to be considered, so C = 0 can be set, that is, V FA =1 - F + R.

[0067] In this embodiment, optionally, determining the volume correction coefficient of the to-be-detected structural trap according to the reference correction coefficient includes: when the trap type is anticlinal, determining the volume correction coefficient of the to-be-detected structural trap according to the amplitude correction coefficient and the reservoir correction coefficient in the reference correction coefficient; when the trap type is fault-anticlinal, determining the volume correction coefficient of the to-be-detected structural trap according to the amplitude correction coefficient, the fault correction coefficient and the reservoir correction coefficient in the reference correction coefficient; when the trap type is fault block, determining the volume correction coefficient of the to-be-detected structural trap according to the fault correction coefficient and the reservoir correction coefficient in the reference correction coefficient.

[0068] Among them, the anticlinal structural trap is affected by two aspects: the top surface amplitude and the inclination of the reservoir occurrence. Therefore, the volume correction coefficient of the anticlinal structural trap can be determined according to the amplitude correction coefficient and the reservoir correction coefficient; the fault-anticlinal structural trap is affected by three aspects: the top surface amplitude, the trap-controlling fault and the inclination of the reservoir occurrence. Therefore, the volume correction coefficient of the fault-anticlinal structural trap can be determined according to the amplitude correction coefficient, the fault correction coefficient and the reservoir correction coefficient; the fault-block structural trap is affected by two aspects: the trap-controlling fault and the inclination of the reservoir occurrence. Therefore, the volume correction coefficient of the fault-block structural trap can be determined according to the fault correction coefficient and the reservoir correction coefficient.

[0069] In this embodiment, optionally, determining the volume correction coefficient of the to-be-detected structural trap according to the amplitude correction coefficient and the reservoir correction coefficient in the reference correction coefficient includes: determining the volume correction coefficient of the to-be-detected structural trap through a first volume formula, and the first volume formula is expressed as V FA = 1 - C + R; where V FA is the volume correction coefficient, C is the amplitude correction coefficient, and R is the reservoir correction coefficient; determining the volume correction coefficient of the to-be-detected structural trap according to the amplitude correction coefficient, the fault correction coefficient and the reservoir correction coefficient in the reference correction coefficient includes: determining the volume correction coefficient of the to-be-detected structural trap through a second volume formula, and the second volume formula is expressed as V FA = 1 - C - F + R; where F is the fault correction coefficient; determining the volume correction coefficient of the to-be-detected structural trap according to the fault correction coefficient and the reservoir correction coefficient in the reference correction coefficient includes: determining the volume correction coefficient of the to-be-detected structural trap through a third volume formula, and the third volume formula is expressed as V FA = 1 - F + R.

[0070] Among them, the first volume formula can be used to determine the volume correction coefficient of an anticline-type structural trap, the second volume formula can be used to determine the volume correction coefficient of a fault-anticline-type structural trap, and the third volume formula can be used to determine the volume correction coefficient of a fault-block-type structural trap. In this embodiment, when determining the volume correction coefficient of the structural trap to be measured, only the reference correction coefficient corresponding to the trap type needs to be substituted into the corresponding volume formula, and the volume correction coefficient of the structural trap to be measured of the corresponding trap type can be determined through simple calculation.

[0071] Exemplarily, the first volume formula for determining the volume correction coefficient of an anticline-type structural trap can be specifically expressed as V FA = 1 - C + R = 1 - H r (cotα1 + cotα r ) / 2L r + 1 / cosγ - 1 = 1 / cosγ - H r (cotα1 + cotα r ) / 2L r . Among them, L r and H r are respectively the reservoir cross-sectional length and the reservoir cross-sectional thickness within the anticline-type trap range on the standard cross-section under the ideal angle, α1 and α r are respectively the dip angles of the left-wing top surface and the right-wing top surface of the anticline-type trap on the standard cross-section, and γ is the dip angle of the reservoir within the anticline-type trap. Further, when α1 = α r = α, the first volume formula can be simplified to V FA = 1 / cosγ - H r cotα / L r .

[0072] Exemplarily, the second volume formula for determining the volume correction coefficient of a fault-anticline-type structural trap can be specifically expressed as V FA = 1 - C - F + R = 1 - H r cotα / 2L r - H r tanβ / 2L r + 1 / cosγ - 1 = 1 / cosγ - H r (cotα + tanβ) / 2L r . Among them, L r and H r are respectively the reservoir cross-sectional length and the reservoir cross-sectional thickness within the fault-anticline-type trap range on the standard cross-section under the ideal angle, α is the dip angle of the top surface of the fault-anticline-type trap on the standard cross-section, β is the dip angle of the fault controlling the trap on the standard cross-section of the fault-anticline-type trap, and γ is the dip angle of the reservoir within the fault-anticline-type trap.

[0073] Exemplarily, the third volume formula for determining the volume correction coefficient of a fault-block type structural trap can be specifically expressed as V FA = 1 - F + R = 1 - H r (tanβ1 + tanβ r ) / 2L r + 1 / cosγ - 1 = 1 / cosγ - H r (tanβ1 + tanβ r ) / 2L r . Wherein, L r and H r are respectively the reservoir cross-sectional length and the reservoir cross-sectional thickness within the fault-block type trap range on the standard cross-section at the ideal angle. β1 and β r are respectively the dip angles of the left-wing trap-controlling fault and the right-wing trap-controlling fault of the fault-block type trap on the standard cross-section, and γ is the dip angle of the reservoir within the fault-block type trap. Further, when β1 = β r = β, the third volume formula can be simplified to V FA = 1 / cosγ - H r tanβ / L r .

[0074] In this embodiment, exemplarily, taking the fault-anticline type structural trap as an example, the determination process of the volume correction coefficient will be described. Specifically, first, determine the standard cross-section of the fault-anticline type structural trap according to the cross-section where the target line segment within the fault-anticline type structural trap range is located, see Figure 2B . Wherein, the target line segment aa' is the line segment perpendicular to the trap-controlling fault within the fault-anticline type structural trap range, and the length of the target line segment aa' is equal to half of the length of the third reference line segment bb'. According to the structural map of the fault-anticline type structural trap, L r = 250m and α = 30° can be calculated. According to the well logging interpretation results of the adjacent wells around the fault-anticline type structural trap, H r = 50m can be queried. Wherein, L r and H r respectively represent the reservoir cross-sectional length and the reservoir cross-sectional thickness within the fault-anticline type trap range on the standard cross-section at the ideal angle, and α is the dip angle of the top surface of the fault-anticline type trap on the standard cross-section, see Figure 2B and Figure 3B . At this time, according to the second amplitude function, the amplitude correction coefficient of the fault-anticline type structural trap can be determined as C = H r cotα / 2L r = 50m × cot30° / (2 × 250m) = 0.173. By querying the seismic profile of the fault-anticline type structural trap, β = 35° can be calculated, where β is the dip angle of the trap-controlling fault of the fault-anticline type trap on the standard cross-section. Specifically, it can be seen from Figure 4AAt this time, according to the first fault function, the fault correction coefficient of the faulted anticline type structural trap can be determined as F = H r tanβ / 2L r = 50m × tan 35° / (2 × 250m) = 0.070. By querying the seismic profile of the faulted anticline type structural trap, γ = 10° can be calculated, where γ is the dip angle of the reservoir within the faulted anticline type trap. Specifically, reference can be made to Figure 5 At this time, according to the preset reservoir function, the reservoir correction coefficient of the faulted anticline type structural trap can be determined as R = 1 / cosγ - 1 = 1 / cos 10° - 1 = 0.015. Thus, according to the second volume formula, the volume correction coefficient of the faulted anticline type structural trap can be obtained as V FA = 1 - C - F + R = 1 - 0.173 - 0.070 + 0.015 = 0.772.

[0075] In the technical solution of the embodiment of the present invention, the trap type of the to-be-detected structural trap is determined, and the standard cross-section of the to-be-detected structural trap is determined according to the trap type; the trap types include anticline type, faulted anticline type, and fault block type, and the standard cross-section is used to represent the plane where the bottom surface of the to-be-detected structural trap is located; the target parameter information of the to-be-detected structural trap on the standard cross-section is determined, and the reference correction coefficient of the to-be-detected structural trap is determined according to the target parameter information; the reference correction coefficient includes at least two of the amplitude correction coefficient, the fault correction coefficient, and the reservoir correction coefficient; the volume correction coefficient of the to-be-detected structural trap is determined according to the reference correction coefficient. This technical solution can quickly and accurately obtain the volume correction coefficient of the structural trap approaching the underground actual situation based on the standard cross-section of the structural trap, which helps to improve the prediction speed and prediction accuracy of the resource volume of the structural trap.
