[0031] Embodiment 1

[0032] Figure 1 This is a flow chart of a seismic data interpretation method provided in the first embodiment of the present invention. This embodiment is applicable to the case of automatically interpreting seismic data at sensitive locations. The method can be executed by a seismic data interpretation device. The seismic data interpretation device can be implemented in the form of hardware and / or software. The seismic data interpretation device can be configured in a terminal and / or a server. Figure 1 As shown, the method includes:

[0033] S110, acquiring an original seismic data volume, and performing coherent slicing processing on the original seismic data volume to obtain coherent volume slices of a target layer.

[0034] In this embodiment, the original seismic data volume refers to a three-dimensional amplitude data volume that can characterize stratum characteristics. The coherent volume slice of the target layer can be used to identify spatial distribution characteristics such as faults and lithology.

[0035] Specifically, the original seismic data volume can be obtained from a preset storage path of an electronic device, or the original seismic data volume can be obtained by collecting oil and gas exploration equipment. Optionally, the original seismic data volume is subjected to coherent slicing processing to obtain a seismic coherent data volume, including: coherently processing the original seismic data volume to obtain a seismic coherent data volume; horizontally slicing the seismic coherent data volume to obtain a coherent volume slice of the target layer.

[0036] S120, performing an azimuth search on the coherent volume slice of the target layer to obtain at least one target coherent azimuth.

[0037] In this embodiment, the target coherent azimuth refers to the result of azimuth search on the coherent volume slice of the target layer.

[0038] Exemplarily, the target coherence orientation may be an orientation where the sum of coherence values ​​in the coherence volume slice of the target layer is the largest or an orientation where the sum of coherence values ​​is within a preset coherence value range, which is not specifically limited here.

[0039] S130, acquiring a target fracture orientation from the target coherent orientation, and rotating the target fracture orientation to obtain a sensitive orientation.

[0040] In this embodiment, the target fracture azimuth refers to the azimuth at which the fracture needs to be observed. It should be noted that the imaging accuracy of the same fracture in different azimuth data volumes varies, and the azimuth at which the fracture imaging is clearest can be called a sensitive azimuth.

[0041] Specifically, the target fracture orientation can be determined according to the orientation energy of the target coherent orientation. Specifically, the orientation with the highest orientation energy among the target coherent orientations can be determined as the target fracture orientation, or the orientation with the second highest orientation energy among the target coherent orientations can be determined as the target fracture orientation, etc., which are not specifically limited here.

[0042] After obtaining the target fracture orientation, the target fracture orientation can be rotated to obtain a sensitive orientation with the clearest fracture imaging, wherein the rotation angle can be any angle, which is not specifically limited here, for example, the rotation angle can be 30 degrees, 60 degrees or 90 degrees, etc.

[0043] S140, performing seismic data interpretation on the seismic data volume of the sensitive location to obtain a seismic interpretation result of the sensitive location.

[0044] In some optional embodiments, before performing seismic data interpretation on the seismic data volume of the sensitive orientation to obtain the seismic interpretation result of the sensitive orientation, it also includes: updating the main survey line orientation to the sensitive orientation and obtaining the seismic data volume of the sensitive orientation.

[0045] For example, Figure 2 It is a comparative schematic diagram of seismic interpretation results provided according to an embodiment of the present invention. Figure 2 The image on the left in the middle is the seismic interpretation result of the target fault orientation, and the direction of the arrow in the square is the target fault orientation; Figure 2 The image on the middle right is the seismic interpretation result of the sensitive orientation, and the direction of the arrow in the square is the sensitive orientation. Comparing the two images, it can be seen that the fault at the position indicated by the arrow in the seismic interpretation result of the sensitive orientation is clearer, which can effectively improve the recognition accuracy of the structure and fault.

[0046] The technical solution of the embodiment of the present invention obtains the original seismic data body, performs coherent slicing processing on the original seismic data body, obtains the coherent volume slices of the target layer, and then performs azimuth search on the coherent volume slices of the target layer to obtain at least one target coherent azimuth, obtains the target fault azimuth from the target coherent azimuth, rotates the target fault azimuth to obtain the sensitive azimuth, and realizes the automatic selection of the sensitive azimuth, and then performs seismic data interpretation on the seismic data body of the sensitive azimuth to obtain the seismic interpretation results of the sensitive azimuth. Compared with the seismic interpretation results of the original azimuth, the seismic interpretation results of the sensitive azimuth can effectively improve the recognition accuracy of structures and faults.

[0047] Embodiment 2

[0048] Figure 2 A flowchart of a seismic data interpretation method provided for the second embodiment of the present invention, the method of this embodiment can be combined with the various optional schemes in the seismic data interpretation method provided in the above embodiments. The seismic data interpretation method provided in this embodiment is further optimized. Optionally, an azimuth search is performed on the coherent volume slice of the target layer to obtain at least one target coherent azimuth, including: for any azimuth in any calculation time window, the azimuth energy corresponding to the azimuth is determined according to the coherence value corresponding to the coherent volume slice of the target layer in the azimuth; the azimuth energies corresponding to each orientation in the current calculation time window are compared, and the candidate coherent azimuth in the current calculation time window is determined based on the comparison result; the candidate coherent azimuths in each calculation time window are summarized to obtain the target coherent azimuth.

[0049] like Figure 2 As shown, the method includes:

[0050] S210: Acquire an original seismic data volume, and perform coherent slicing processing on the original seismic data volume to obtain coherent volume slices of a target layer.

[0051] S220. For any orientation in any calculation time window, determine the orientation energy corresponding to the orientation according to the coherence value corresponding to the coherence volume slice of the target layer at the orientation.

[0052] The azimuth energy corresponding to the azimuth may be the sum of the coherence values ​​at the azimuth.

[0053] S230, comparing the azimuth energies corresponding to the various azimuths in the current calculation time window, and determining the candidate coherent azimuths in the current calculation time window based on the comparison result.

[0054] The candidate coherent orientation is the orientation with the largest sum of coherent values ​​among all orientations in the current calculation time window.

[0055] Specifically, the azimuth energies corresponding to adjacent azimuths in the current calculation time window are compared in turn until all azimuths in the current calculation time window are compared, the azimuth corresponding to the maximum azimuth energy among all azimuths is retained, and the azimuth corresponding to the maximum azimuth energy among all azimuths is determined as the candidate coherent azimuth in the current calculation time window.

[0056] S240: Summarize the candidate coherent directions in each calculation time window to obtain the target coherent direction.

[0057] The target coherent orientation refers to the set of candidate coherent orientations in all time windows.

[0058] Exemplarily, within a preset calculation window of a fixed radius, any azimuth can be selected as the starting point, and the starting azimuth is set to 0°, and then the coherence values ​​at the starting azimuth are summed; further, the azimuth is moved to an adjacent azimuth, wherein the default increment of the angle of the adjacent azimuth may be 1°, and the sum of the coherence values ​​at the adjacent azimuths is calculated, and the sum of the coherence values ​​at the starting azimuth (i.e., 0°) and the adjacent azimuth (i.e., 1°) is compared, and the azimuth with the larger sum of the coherence values ​​is recorded. The azimuth with the larger sum is recorded as X°; then move to the next adjacent azimuth, that is, move to 2°, and then calculate the sum of the coherence values ​​on the 2° azimuth, and compare the sum of the coherence values ​​on the azimuth X° and the azimuth 2°. If the sum of the coherence values ​​of the azimuth 2° is greater than the sum of the coherence values ​​of the azimuth X°, then replace the recorded azimuth with the new azimuth 2°, otherwise the original recorded azimuth remains unchanged; continue to move the azimuth and compare the sum of the coherence values ​​until 180 azimuths are compared, so as to obtain the azimuth with the largest sum of the coherence values ​​among all azimuths in the current calculation time window. Move to the next time window and repeat the above steps until the azimuths in all time windows are obtained, that is, the target coherent azimuth is obtained.

[0059] S250, acquiring a target fracture orientation from the target coherent orientation, and rotating the target fracture orientation to obtain a sensitive orientation.

[0060] S260: Perform seismic data interpretation on the seismic data volume of the sensitive location to obtain a seismic interpretation result of the sensitive location.

[0061] The technical solution of the embodiment of the present invention determines the azimuth energy corresponding to any azimuth in any calculation time window according to the coherence value corresponding to the coherence volume slice of the target layer in the azimuth, and then compares the azimuth energies corresponding to each azimuth in the current calculation time window, determines the candidate coherent azimuth in the current calculation time window based on the comparison result, and then summarizes the candidate coherent azimuths in each calculation time window to obtain the target coherent azimuth, thereby realizing accurate search of the azimuth.

[0062] Embodiment 3

[0063] Figure 3 This is a flow chart of a seismic data interpretation method provided in Embodiment 3 of the present invention. The method of this embodiment can be combined with each optional solution in the seismic data interpretation method provided in the above embodiments. The seismic data interpretation method provided in this embodiment is further optimized. Optionally, the target fault azimuth is rotated 90 degrees to obtain a sensitive azimuth.

[0064] like Figure 3 As shown, the method includes:

[0065] S310: Acquire an original seismic data volume, and perform coherent slicing processing on the original seismic data volume to obtain coherent volume slices of a target layer.

[0066] S320: Perform an azimuth search on the coherent volume slice of the target layer to obtain at least one target coherent azimuth.

[0067] S330, acquiring a target fracture orientation from the target coherent orientation, and rotating the target fracture orientation by 90 degrees to obtain a sensitive orientation.

[0068] S340, performing seismic data interpretation on the seismic data volume of the sensitive orientation to obtain a seismic interpretation result of the sensitive orientation.

[0069] It should be noted that when observing along the fault azimuth, the changes caused by the observed cracks are small, such as travel time delay, amplitude attenuation, and frequency reduction, while the changes caused by the observed cracks when observing along the normal azimuth of the cracks are the largest. Therefore, by interpreting seismic data at the sensitive azimuth obtained by rotating the target fault azimuth by 90 degrees, the accuracy of seismic data interpretation can be effectively improved.

[0070] Optionally, the target fracture orientation is obtained from the target coherent orientation, including: generating an energy histogram based on the target coherent orientation and the orientation energy corresponding to the target coherent orientation; determining the candidate coherent orientation corresponding to the highest energy peak in the energy histogram as the main fracture orientation; determining the candidate coherent orientation corresponding to the second highest energy peak in the energy histogram as the secondary fracture orientation; and determining the main fracture orientation or the secondary fracture orientation as the target fracture orientation.

[0071] The horizontal axis of the energy histogram is the target coherent azimuth, and the vertical axis is the azimuth energy corresponding to the target coherent azimuth. Specifically, the main fracture azimuth or the secondary fracture azimuth can be determined as the target fracture azimuth according to the detection requirements to achieve targeted observation.

[0072] The technical solution of the embodiment of the present invention can effectively improve the accuracy of seismic data interpretation by performing seismic data interpretation on the sensitive azimuth obtained by rotating the target fault azimuth by 90 degrees.
