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 a fault-block type trap. Background Art

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

[0003] In the prior art, the volume correction coefficient of the fault-block trap is usually assigned directly based on personal experience or expert scoring method when predicting the resource volume of the fault-block trap, or even the influence of this parameter on the resource prediction result is directly ignored. The resource volume of the fault-block trap obtained in this way usually overestimates or underestimates the volume of the fault-block trap, and the result has obvious errors, so it cannot truly reflect the actual resource potential of the underground, which directly affects the exploration potential evaluation and exploration plan deployment of the fault-block trap.

[0040] Among them, the reference correction coefficient can be used as a basis for determining the volume correction coefficient of the fault-block type trap to be measured. Specifically, the reference correction coefficient refers to the fault correction coefficient and the reservoir correction coefficient. Among them, the fault 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 caused by the influence of the controlled fault of the fault-block type trap to be measured, 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 fault-block 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 caused by the influence of the reservoir dip inclination of the fault-block type trap to be measured.

[0041] In this embodiment, after determining the target parameter information of the fault-block trap to be detected on the standard cross section, the reference correction coefficients of the fault-block trap to be detected, namely the fault correction coefficient and the reservoir correction coefficient, can be determined according to the target parameter information. Optionally, determining a reference correction coefficient of a block-type trap to be measured according to target parameter information includes: determining a fault correction coefficient of the block-type trap to be measured according to fault parameter information in the target parameter information and a preset fault function; wherein the fault parameter information includes a reservoir cross-sectional length and a reservoir cross-sectional thickness within the range of the block-type trap to be measured on a standard cross-sectional area at an ideal angle, and a left-wing controlling fault dip and a right-wing controlling fault dip of the block-type trap to be measured on the standard cross-sectional area; the preset fault function is used to describe a mapping relationship between the fault parameter information and the fault correction coefficient; determining a reservoir correction coefficient of the block-type 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 a reservoir dip within the block-type trap to be measured, and the preset reservoir function is used to describe a mapping relationship between the reservoir parameter information and the reservoir correction coefficient.

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

[0043] Specifically, Figure 2 As shown in the right figure in the figure, the cross-sectional area of ​​the fault block 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 ​​a fault-block type structural trap provided in the first embodiment of the present invention. The first cross-sectional area can be used to characterize the cross-sectional area caused by the influence of the controlled fault of the fault-block type structural trap. Figure 3 As shown, the first cross-sectional area can be expressed as 1 / 2×H r ×H r ×(tanβ 1 +tanβ r ). Therefore, according to the ratio of the first cross-sectional area to the second cross-sectional area, the expression of the preset fault function can be obtained as F=1 / 2×H r ×H r ×(tanβ 1 +tanβ r ) / (L r ×H r )=H r (tanβ 1 +tanβ r ) / 2L r . Furthermore, when β 1 =β r =β, the preset fault function can be simplified to F = H r tanβ / L r After obtaining the target parameter information, the fault parameter information in the target parameter information can be substituted into the preset fault function, and the fault correction coefficient of the fault-block type structural trap to be measured can be obtained through calculation.

[0044] Among them, the reservoir parameter information may refer to the parameter information associated with determining the reservoir correction coefficient in the target parameter information of the fault-block type trap to be measured. Specifically, the reservoir parameter information includes the reservoir dip in the fault-block type trap to be measured. The preset reservoir function may refer to a pre-set functional relationship for determining the reservoir correction coefficient of the fault-block type 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 fault-block type trap to be measured.

[0045] Specifically, Figure 2 As shown in the right figure in the figure, the cross-sectional area of ​​the fault block 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 ​​a fault-block type structural trap provided in Example 1 of the present invention. The ideal state refers to a state at an ideal angle, and the third cross-sectional area can be used to characterize the cross-sectional area of ​​the fault-block type trap caused by the influence of the reservoir occurrence inclination. 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 fault-block 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 fault-block trap to be measured can be obtained through calculation.

[0046] S130, determining a volume correction coefficient of the fault-block trap to be detected according to the reference correction coefficient.

[0047] In this embodiment, after determining the reference correction coefficient of the fault-block type trap to be detected, the volume correction coefficient of the fault-block type trap to be detected can be further determined according to the reference correction coefficient. Optionally, determining the volume correction coefficient of the fault-block type trap to be detected according to the reference correction coefficient includes: determining the volume correction coefficient of the fault-block type trap to be detected by a preset volume function, and the expression of the preset volume function is as follows: V FA =1-F+R; where V FA is the volume correction factor, F is the fault 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 a fault-block type structural trap. Specifically, the preset volume function is represented by V FA =1-F+R. In this embodiment, when determining the volume correction coefficient of the fault-block trap to be tested, it is only necessary to substitute the reference correction coefficients (fault correction coefficient and reservoir correction coefficient) of the fault-block 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-F+R=1-H r (tanβ 1 +tanβ r ) / 2L r +1 / cosγ-1=1 / cosγ-H r (tanβ 1 +tanβ r ) / 2L r Among them, L r and H r are the length and thickness of the reservoir cross section within the fault block trap to be tested on the standard cross section at the ideal angle, β 1 and β r are the left-wing controlling fault dip angle and the right-wing controlling fault dip angle of the fault-block trap to be tested on the standard cross section, respectively, and γ is the reservoir dip angle in the fault-block trap to be tested. 1 =β r =β, the preset volume function can be simplified to V FA =1 / cosγ-H r tanβ / L r .

[0049] For example, firstly, the standard cross section of the fault-block type trap to be tested is determined according to the cross section where the target line segment within the range of the fault-block type trap to be tested is located. ′ With bb ′ Parallel, and aa ′ Length equal to bb ′ Half the length, see Figure 2Assume that bb is obtained based on the structural diagram of the fault-block trap to be tested. ′ The length is 500m, so we can get L r =500m / 2=250m. Based on the logging interpretation results of the adjacent wells around the fault-block trap to be tested, H r =50m, β can be calculated based on the seismic profile of the fault-block trap to be tested. 1 =35° and β r =30°. At this time, according to the preset fault function, the fault correction coefficient of the fault block trap to be tested can be obtained as F=H r (tanβ 1 +tanβ r ) / 2L r =50m×(tan 35°+tan 30°) / (2×250m)=0.128. By querying the seismic profile of the fault block trap to be tested, γ=10° can be calculated. At this time, according to the preset reservoir function, the reservoir correction coefficient of the fault block 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 fault block trap to be tested can be obtained as V FA =1-F+R=1-0.128+0.015=0.897.
