Description

Technical Field

[0001] The invention relates to the technical field of geological research, and in particular to a method, device, equipment and medium for determining a volume correction coefficient of anticline-type closures. Background Art

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

[0003] In the prior art, the volume correction coefficient of anticline traps is usually assigned directly based on personal experience or expert scoring when predicting the resources of anticline traps, or even the influence of this parameter on the resource prediction results is directly ignored. The resources of anticline traps obtained in this way usually overestimate or underestimate the volume of anticline traps, and the results have obvious errors, so they cannot truly reflect the actual resource potential of the underground, which directly affects the exploration potential evaluation and exploration plan deployment of anticline traps.

The ideal angle refers to a reservoir dip of 0 degrees.′ The location is the embodiment of L r The mean position of the impact on the bottom area of ​​the anticline trap is thus selected to be representative of the standard cross section.

[0039] S120, determining a reference correction coefficient of the anticline trap to be measured according to the target parameter information; the reference correction coefficient refers to an amplitude correction coefficient and a reservoir correction coefficient.

[0040] Among them, the reference correction coefficient can be used as a basis for determining the volume correction coefficient of the anticline type trap to be measured. Specifically, the reference correction coefficient refers to the amplitude correction coefficient and the reservoir correction coefficient. 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, the first reference area refers to the cross-sectional area of ​​the anticline type trap to be measured caused by the influence of the top surface amplitude, the second cross-sectional area is determined based on the second reference area, the second reference area refers to the cross-sectional area of ​​the anticline type trap to be measured at an ideal angle, the ideal angle refers to the reservoir inclination of 0 degrees, the reservoir 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, the third reference area refers to the cross-sectional area of ​​the anticline type trap to be measured caused by the influence of the reservoir occurrence inclination.

[0041] In this embodiment, after determining the target parameter information of the anticline trap to be measured on the standard cross section, the reference correction coefficient of the anticline trap to be measured, that is, the amplitude correction coefficient and the reservoir correction coefficient, can be determined according to the target parameter information. Optionally, determining the reference correction coefficient of the anticline trap to be measured according to the target parameter information includes: determining the amplitude correction coefficient of the anticline trap to be measured according to the amplitude parameter information in the target parameter information and a preset amplitude function; wherein the amplitude parameter information includes the reservoir cross-section length and reservoir cross-section thickness within the range of the anticline trap to be measured on the standard cross section at an ideal angle, and the left wing top surface inclination angle and the right wing top surface inclination angle of the anticline trap to be measured on the standard cross section; the preset amplitude function is used to describe the mapping relationship between the amplitude parameter information and the amplitude correction coefficient; determining the reservoir correction coefficient of the anticline trap to be measured according to the reservoir parameter information in the target parameter information and the preset reservoir function; wherein the reservoir parameter information includes the reservoir inclination angle within the anticline trap to be measured, and the preset reservoir function is used to describe the mapping relationship between the reservoir parameter information and the reservoir correction coefficient.

[0042] Among them, the amplitude parameter information may refer to the parameter information associated with the amplitude correction coefficient in the target parameter information of the anticline trap to be measured. Specifically, the amplitude parameter information includes the reservoir cross-section length and reservoir cross-section thickness within the range of the anticline trap to be measured on the standard cross-section at an ideal angle, and the left wing top surface inclination angle and the right wing top surface inclination angle of the anticline trap to be measured on the standard cross-section. The preset amplitude function may refer to a pre-set functional relationship for determining the amplitude correction coefficient of the anticline trap to be measured, which can be used to describe the mapping relationship between the amplitude parameter information and the amplitude correction coefficient. Optionally, the expression of the preset amplitude function is as follows: C=H r (cotα 1 +cotα r ) / 2L r ; Where C is the amplitude correction coefficient, L r is the reservoir cross-section length within the anticline trap to be measured on the standard cross-section at the ideal angle, H r is the reservoir cross-section thickness within the anticline trap to be measured on the standard cross section at the ideal angle, α 1 is the left wing top surface inclination angle of the anticline trap to be tested on the standard cross section, α r It is the inclination angle of the top surface of the right wing of the anticline trap to be measured on the standard cross section.

[0043] Specifically, Figure 2 As shown in the right figure in the figure, the cross-sectional area of ​​the anticline trap to be tested at the ideal angle (i.e., the second cross-sectional area) can be expressed as L r ×H r . Figure 3 A schematic diagram of a first cross-sectional area of ​​an anticline structural trap provided in Example 1 of the present invention. The first cross-sectional area can be used to characterize the cross-sectional area of ​​the anticline structural trap caused by the top surface amplitude. Figure 3 As shown, the first cross-sectional area can be expressed as 1 / 2×H r ×H r ×(cotα 1 +cotα r ). Therefore, according to the ratio of the first cross-sectional area to the second cross-sectional area, the expression of the preset amplitude function can be obtained as C=1 / 2×H r ×H r ×(cotα 1 +cotα r ) / (L r ×H r )=H r (cotα 1 +cotα r ) / 2L r . Furthermore, when α 1 =α r=α, the preset amplitude function can be simplified to C = H r cotα / L r After obtaining the target parameter information, the amplitude parameter information in the target parameter information can be substituted into the preset amplitude function, and the amplitude correction coefficient of the anticline trap to be measured can be obtained through calculation.

[0044] Wherein, the reservoir parameter information may refer to the parameter information associated with determining the reservoir correction coefficient in the target parameter information of the anticline trap to be measured. Specifically, the reservoir parameter information includes the reservoir dip in the anticline trap to be measured. The preset reservoir function may refer to a pre-set functional relationship for determining the reservoir correction coefficient of the anticline trap to be measured, which can be used to describe the mapping relationship between the reservoir parameter information and the reservoir correction coefficient. Optionally, the expression of the preset reservoir function is as follows: R=1 / cosγ-1; wherein R is the reservoir correction coefficient, and γ is the reservoir dip in the anticline trap to be measured.

[0045] Specifically, Figure 2 As shown in the right figure in the figure, the cross-sectional area of ​​the anticline trap to be tested at the ideal angle (i.e., the second cross-sectional area) can be expressed as L r ×H r . Figure 4 A schematic diagram of the third cross-sectional area of ​​an anticline structural trap provided in Example 1 of the present invention. The ideal state may refer to a state at an ideal angle, and the third cross-sectional area may be used to characterize the cross-sectional area of ​​the anticline trap caused by the inclination of the reservoir. Figure 4 As shown, the third 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 It represents the length of the actual reservoir cross section caused by the inclination of the reservoir occurrence within the anticline trap. According to the ratio of the third cross-sectional area to the second cross-sectional area, the expression of the preset reservoir function can be obtained as R = L r ×H r ×(1 / cosγ-1) / (L r ×H r )=1 / cosγ-1. After obtaining the target parameter information, the reservoir parameter information in the target parameter information can be substituted into the preset reservoir function, and the reservoir correction coefficient of the anticline trap to be measured can be obtained through calculation.

[0046] S130, determining a volume correction coefficient of the anticline trap to be measured according to the reference correction coefficient.

[0047] In this embodiment, after determining the reference correction coefficient of the anticline trap to be measured, the volume correction coefficient of the anticline trap to be measured can be further determined according to the reference correction coefficient. Optionally, determining the volume correction coefficient of the anticline trap to be measured according to the reference correction coefficient includes: determining the volume correction coefficient of the anticline trap to be measured by a preset volume function, and the expression of the preset volume function is as follows: V FA =1-C+R; where V FA is the volume correction factor, C is the amplitude correction factor, and R is the reservoir correction factor.

[0048] The preset volume function may refer to a pre-set functional relationship of a volume correction coefficient for determining anticline-type structural traps. Specifically, the preset volume function is represented by V FA =1-C+R. In this embodiment, when determining the volume correction coefficient of the anticline trap to be tested, it is only necessary to substitute the reference correction coefficient (amplitude correction coefficient and reservoir correction coefficient) of the anticline trap to be tested into the preset volume function, and the volume correction coefficient can be obtained through simple calculation. The preset volume function can be specifically expressed as V FA =1-C+R=1-H r (cotα 1 +cotα r ) / 2L r +1 / cosγ-1=1 / cosγ-H r (cotα 1 +cotα r ) / 2L r Among them, L r and H r They represent the length and thickness of the reservoir cross section within the anticline trap to be measured on the standard cross section at the ideal angle, respectively. 1 and α r They represent the left wing top surface inclination and the right wing top surface inclination of the anticline trap to be tested on the standard cross section, and γ is the reservoir inclination in the anticline trap to be tested. 1 =α r =α, the preset volume function can be simplified to V FA =1 / cosγ-H r cotα / L r .

[0049] For example, the standard cross section of the anticline trap to be tested is first determined based on the cross section where the target line segment within the anticline trap to be tested is located. The target line segment aa′ is a line passing through the center point of the anticline within the anticline trap to be tested, and the length of aa′ is equal to the average length of bb′ and cc′, see Figure 2 Assuming that the lengths of bb′ and cc′ are 500m and 450m respectively according to the structural diagram of the anticline trap to be tested, we can get L r =(500m+450m) / 2=475m. According to the logging interpretation results of the adjacent wells around the anticline trap to be tested, H r =50m, according to the top structural diagram of the anticline trap to be tested, α can be calculated 1 =30° and α r =25°. At this time, according to the preset amplitude function, the amplitude correction coefficient of the anticline trap to be tested can be obtained as C=H r (cotα 1 +cotα r ) / 2L r =50m×(cot30°+cot25°) / (2×475m)=0.204. By querying the seismic profile of the anticline trap to be tested, γ=10° can be calculated. At this time, according to the preset reservoir function, the reservoir correction coefficient of the anticline trap to be tested can be determined as R=1 / cosγ-1=1 / cos 10°-1=0.015. According to the preset volume function, the volume correction coefficient of the anticline trap to be tested can be obtained as V FA =1-C+R=1-0.204+0.015=0.811.

[0050] The technical solution of the embodiment of the present invention determines the target parameter information of the anticline trap to be measured on the standard cross section; the standard cross section is used to represent the plane where the bottom surface of the anticline trap to be measured is located; the reference correction coefficient of the anticline trap to be measured is determined according to the target parameter information; the reference correction coefficient refers to the amplitude correction coefficient and the reservoir correction coefficient; the volume correction coefficient of the anticline trap to be measured is determined according to the reference correction coefficient.
