Description

Technical Field

[0001] This application belongs to the technical field of oil and gas exploration, especially the technical field of seismic data processing for oil and gas exploration. Specifically, it relates to a method and device for quality control of seismic horizon interpretation results. Background Art

[0002] When performing horizon interpretation of seismic data in the time domain, the existing methods generally perform tracking in the line direction and trace direction of the event respectively. As the interpretation grid is gradually refined, a complete seismic horizon interpretation result is finally formed. At the intersection of the line and trace directions, the t0 time of the same horizon should be equal, that is, the so-called closure of the section. In particular, when there is a fault within the layer, the fault throw should be taken into account. Generally, the closure error should not exceed half a phase. If this requirement is exceeded, it means that the same phase of the reflected wave is not being tracked during correlation, and there are deviations in the interpretation results, which need to be modified and re-correlated and interpreted. Otherwise, it will have a serious impact on subsequent geological understanding, structural mapping, and various attribute extraction results. It can be seen that the closure of horizon interpretation data is an effective means to check or verify the accuracy of seismic data interpretation. In other words, the calculation of the closure error in the line and trace directions of 3D seismic interpretation is an effective quality control method for seismic horizon tracking interpretation.

[0003] Relatively speaking, there are few evaluation methods for quality control of 3D seismic data interpretation accuracy in the existing technology. Relatively reliable methods include, for example, the horizon flattening quality control method or the color scale along the horizon quality control method, etc. However, such quality control methods are often greatly affected by subjective factors and require the cooperation of multiple methods to improve the effect, and it is gradually difficult to meet the accuracy requirements and the increasingly high efficiency requirements of seismic interpretation work. In particular, quantitative evaluation methods urgently need to be innovated. In recent years, there have only been a few informally released programming procedures, and their usability and stability need to be improved. The steps are relatively cumbersome and the operation convenience is not high, resulting in problems such as low work efficiency and inconsistent result output forms, which urgently need to be solved.

[0083] Embodiment 1:

[0084] An embodiment of the present invention provides a specific implementation manner of a method for quality control of seismic horizon interpretation results. Refer to Figure 1 , and specifically includes the following content:

[0085] Step 100: On the target seismic horizon interpretation result, establish a frame line passing through the intersection of the main survey line and the connecting survey line to generate a first frame line interpretation result; wherein, the frame line is two straight lines intersecting at the intersection.

[0086] Step 200: Subtract the time difference between the first frame line interpretation result and the seismic horizon interpretation result to generate a second frame line interpretation result.

[0087] Step 300: Subtract the time difference between the seismic horizon interpretation result and the second frame line interpretation result to generate a third frame line interpretation result.

[0088] Step 400: Perform quality control on the target seismic horizon interpretation result according to the second frame line interpretation result and the third frame line interpretation result.

[0089] As can be seen from the above description, an embodiment of the present invention provides a method for quality control of seismic horizon interpretation results, including: First, on the target seismic horizon interpretation result, establish a frame line passing through the intersection of the main survey line and the connecting survey line to generate a first frame line interpretation result; wherein, the frame line is two straight lines intersecting at the intersection. Then, subtract the time difference between the first frame line interpretation result and the seismic horizon interpretation result to generate a second frame line interpretation result; subtract the time difference between the seismic horizon interpretation result and the second frame line interpretation result to generate a third frame line interpretation result; finally, perform quality control on the target seismic horizon interpretation result according to the second frame line interpretation result and the third frame line interpretation result.

[0090] The quality control method for seismic horizon interpretation results provided by the embodiments of the present invention locates the intersection positions of seismic horizon interpretation data lines and trace directions by building framework lines and combining corresponding calculation formulas. On this basis, the data at the intersection positions in two directions are extracted. If there are differences in the data of the line and trace directions at the intersection positions and the difference value exceeds the normal range, it is identified as a "jumping point" that is not closed in seismic horizon interpretation, thereby realizing the quality control of the seismic horizon interpretation effect.

[0091] Embodiment 2:

[0092] It can be understood that in the field of oil and gas exploration technology, the seismic horizon interpretation results are very important, which can provide information about the underground structure and properties of potential oil and gas reservoirs. Preferably, the seismic horizon interpretation results include the following aspects: Oil and gas reservoir identification: Through seismic horizon interpretation, the location, thickness, and morphology of potential oil and gas reservoirs can be determined. The reflection characteristics and amplitude changes of seismic waves can be used to identify potential reservoirs, such as sandstone, carbonate rock, or shale, etc. Reservoir property evaluation: Seismic horizon interpretation can provide information about reservoir properties, such as porosity, permeability, saturation, etc. By analyzing the changes in seismic wave velocity, frequency, and amplitude, the physical properties of the reservoir can be inferred and its potential oil and gas reserves can be evaluated. Underground structure analysis: Seismic horizon interpretation can reveal the characteristics of underground structures, such as faults, folds, and basins, etc. By analyzing the reflection characteristics and fault displacements on seismic profiles, the geometric morphology and movement history of structural features can be determined, providing important references for oil and gas exploration. Directional drilling decision-making: The seismic horizon interpretation results can be used to determine drilling targets and paths. By analyzing the location, morphology, and thickness of the reservoir, the optimal drilling location and direction can be determined, improving the success rate of oil and gas exploration.

[0093] In addition, the main line (Main Line) refers to the main line arranged in seismic exploration, which is arranged along the predetermined seismic profile direction. The purpose of the main line is to obtain seismic data along a specific seismic profile for the interpretation and analysis of underground structures and reservoir characteristics. The seismic data on the main line usually has a high spatial resolution and can provide more detailed underground information, such as the location, thickness, and properties of oil and gas reservoirs, etc.

[0094] The tie line (Tie Line) refers to the auxiliary line connecting the main lines. The role of the tie line is to perform data correction and verification between the main lines to ensure the consistency and accuracy of seismic data. The tie line usually intersects or is adjacent to the main line and passes through the data points of the main line for data verification and correction. The tie lines are usually arranged densely to ensure the continuity and accuracy of seismic data.

[0095] It should be noted that the frame line in step 100 is similar in shape to a cross, that is, two perpendicular intersecting straight lines, one extending in the north-south direction and the other extending in the east-west direction, and the intersection point thereof coincides with the intersection point of the main survey line and the connecting survey line.

[0096] Steps 200 to 300 are based on the mechanism of the closure error of seismic horizon interpretation to accurately identify the "jumping points" where the intersection positions of the midline and the trace direction in the horizon interpretation are not closed, and then to evaluate the quality of the seismic horizon interpretation results.

[0097] In some embodiments of the present invention, referring to Figure 2 , the method for quality control of seismic horizon interpretation results further includes:

[0098] Step 500: Determine the grid size of the main survey line and the connecting survey line according to the interpretation accuracy of the target seismic horizon interpretation result;

[0099] Step 600: Establish the main survey line and the connecting survey line on the target seismic horizon interpretation result according to the grid size.

[0100] In step 500 and step 600, according to the grid accuracy of the horizon interpretation data (for example, 8×8), in the survey network, "frame lines" and points in the directions of the main survey line (Inline), the connecting survey line (Crossline) and the intersection of the two directions are newly established with grids of the same size, and then converted into an interpretation file.

[0101] In some embodiments of the present invention, one straight line direction in the frame line is the north-south direction, and the other straight line direction is the east-west direction;

[0102] The second frame line interpretation result is the target horizon interpretation result of the interpretation result without the intersection point. That is, using the operation function in the interpretation platform, the "frame line" in the Inline direction that has been converted into the interpretation format is calculated with the intersection point (Eliminate where Z=suface(x,y)), and the "frame line" in the main survey line direction with the intersection point position data eliminated is obtained.

[0103] In some embodiments of the present invention, referring to Figure 3 , step 200 includes:

[0104] Step 201: Subtract the time difference between the part corresponding to the main survey line in the first frame line interpretation result and the seismic horizon interpretation result to generate a first sub-interpretation result of the second frame line;

[0105] Using the arithmetic function in the interpretation software, calculate the "frame lines" in the Inline direction and the intersections that have been converted to the interpretation format (Eliminate where Z=suface(x,y)) to obtain the main survey line direction "frame lines" with the intersection position data removed;

[0106] Step 202: Subtract the time difference between the part corresponding to the connecting survey line in the first frame line interpretation result and the seismic horizon interpretation result to generate the second sub-interpretation result of the second frame line;

[0107] Similar to the operation process of the "frame lines" in the main survey line (Inline) direction in Step 201, remove the intersection position data from the "frame lines" in the connecting survey line (Crossline) direction;

[0108] Step 203: Generate the second frame line interpretation result based on the first sub-interpretation result of the second frame line and the second sub-interpretation result of the second frame line.

[0109] In some embodiments of the present invention, see Figure 4 , Step 300 includes:

[0110] Step 301: Subtract the time difference between the seismic horizon interpretation result and the first sub-interpretation result of the second frame line to generate the first sub-interpretation result of the third frame line;

[0111] Make another copy of the seismic horizon interpretation data, and perform an operation (Eliminate where Z=suface(x,y)) on one of the copies and the "frame lines" in the main survey line (Inline) direction with the intersection position data removed;

[0112] Step 302: Subtract the time difference between the seismic horizon interpretation result and the second sub-interpretation result of the second frame line to generate the second sub-interpretation result of the third frame line;

[0113] Similar to the operation process in Step 301, perform an operation (Eliminate where Z=suface(x,y)) on the other copy of the previously copied seismic horizon interpretation data and the "frame lines" in the connecting survey line (Crossline) direction with the intersection position data removed.

[0114] Step 303: Generate the third frame line interpretation result based on the first sub-interpretation result of the third frame line and the second sub-interpretation result of the third frame line.

[0115] In some embodiments of the present invention, see Figure 5 , Step 400 includes:

[0116] Step 401: Perform interpolation operations on the first sub-interpretation result of the third frame line and the second sub-interpretation result of the third frame line respectively to generate the first sub-interpretation result of the differential third frame line and the second sub-interpretation result of the differential third frame line;

[0117] Perform interpolation operations (Seismic operations-Interpolate empty) on the seismic horizon interpretation data in the first sub-interpretation result of the third frame line and the second sub-interpretation result of the third frame line;

[0118] It should be noted that interpolation operation refers to the spatial area that needs to be interpolated due to missing or incomplete data in seismic data processing. Interpolation empty usually appears in the following situations:

[0119] Lack of line coverage: The layout of seismic lines is usually limited and may not cover the entire exploration area. In the areas not covered by the lines, interpolation empty will appear, and interpolation processing is required to fill the missing part of the data.

[0120] Missing or low-quality data: Due to various factors in the seismic data acquisition process, such as instrument failures and data quality problems, some data may be missing or of poor quality. In these areas, interpolation processing is also required to fill the missing part of the data or repair the low-quality data.

[0121] Abnormal noise or abnormal data: There may be abnormal noise or abnormal data in seismic data, which may have a negative impact on interpretation and analysis. To reduce the impact of abnormal data, interpolation processing can be performed on these areas.

[0122] In the interpolation empty area, interpolation algorithms can be used to infer the values of missing or low-quality data. Commonly used interpolation methods include linear interpolation, Kriging interpolation, inverse interpolation, etc. The choice of interpolation method should be determined according to the data characteristics and requirements to obtain as accurate results as possible.

[0123] Step 402: Respectively subtract the time difference between the first sub-interpretation result of the differential third frame line and the second sub-interpretation result of the differential third frame line from the interpretation result of the first frame line to generate the first interpretation result of the intersection point and the second interpretation result of the intersection point;

[0124] Specifically, perform operations (Eliminate where Z=suface(x,y)) on the two interpolated seismic horizon interpretation data respectively with the pre-created "intersection point" interpretation file to obtain two seismic horizon interpretation data that only retain the intersection point positions.

[0125] Step 403: Perform quality control on the target seismic horizon interpretation result according to the first intersection interpretation result and the second intersection interpretation result.

[0126] In some embodiments of the present invention, referring to Figure 6 , Step 403 includes:

[0127] Step 4031: Perform arithmetic operations on the first intersection interpretation result and the second intersection interpretation result to determine the elevation difference of the seismic horizon interpretation data line and the intersection position data in the trace direction of the target seismic horizon interpretation result;

[0128] Specifically, the two obtained seismic horizon interpretation data that only retain the intersection positions are subtracted from each other (Arithmetic operations Z = Z - Surface(x,y)), and thus the "elevation difference" of the seismic horizon interpretation data line and the intersection position data in the trace direction is obtained.

[0129] Step 4032: Perform quality control on the target seismic horizon interpretation result according to the seismic horizon interpretation data line and the elevation difference of the intersection position data in the trace direction.

[0133] Embodiment 3:

[0134] In a specific implementation manner, the present invention also provides a specific implementation manner of a method for quality control of seismic horizon interpretation results. Refer to Figure 7 and Figure 8 , which specifically includes the following steps.

[0135] S1: Conduct horizon tracking interpretation according to a preset interpretation density;

[0136] S2: According to the grid accuracy of the horizon interpretation data, in the survey network, respectively create "frame lines" and points in the directions of the main survey line (Inline), connecting survey line (Crossline), and the intersection of the two directions with grids of the same size, and convert them into interpretation files;

[0137] S3: Calculate the "frame line" in the Inline direction that has been converted into the interpretation format and the intersection points (Eliminate where Z=suface(x,y)), and obtain the "frame line" in the main survey line direction after eliminating the intersection point position data;

[0138] S4: Similar to the operation process of the "frame line" in the main survey line (Inline) direction in step S3, eliminate the intersection point position data of the "frame line" in the connecting survey line (Crossline) direction;

[0139] S5: Make a copy of the seismic horizon interpretation data, and perform an operation (Eliminate where Z=suface(x,y)) on one copy and the "frame line" in the main survey line (Inline) direction after eliminating the intersection point position data;

[0140] S6: Similar to the operation process in step S5, perform an operation (Eliminate where Z=suface(x,y)) on the other copy of the previously copied seismic horizon interpretation data and the "frame line" in the connecting survey line (Crossline) direction after eliminating the intersection point position data.

[0141] S7: Perform interpolation operations (Seismicoperations-Interpolate empty) on the two copies of the seismic horizon interpretation data obtained in steps S5 and S6 respectively;

[0142] S8: Perform an operation (Eliminate where Z=suface(x,y)) on the two interpolated copies of the seismic horizon interpretation data and the pre-established "intersection point" interpretation file respectively, and obtain two copies of the seismic horizon interpretation data that only retain the intersection point positions;

[0143] S9: Subtract the two sets of seismic horizon interpretation data that only retain the intersection positions obtained in step S8 (Arithmetic operations Z = Z - Surface(x,y)), thereby obtaining the "height difference" of the seismic horizon interpretation data line and the intersection position data in the trace direction;

[0144] S10: Convert the "height difference" of the seismic horizon interpretation data line and the intersection position data in the trace direction into a point file, and set the color display to "Z value (height difference) display". Further, by adjusting the color scale, the closed anomaly points can be highlighted by color, which are the "jumping points" that are not closed in the seismic horizon interpretation.

[0145] Here, taking the 3D seismic contiguous processing and interpretation in the Hangjinqi area in the northern Ordos Basin as an example, the quality control method for the seismic horizon interpretation results is further explained: First, in the interpretation software, conduct the tracking and interpretation of the T9 horizon (local) in the work area according to the required interpretation density, with an interpretation accuracy of 8x8, as Figure 9 shown.

[0146] Next, according to the 8x8 accuracy of the T9 horizon interpretation, in the survey network, respectively create "frame lines" and points in the main survey line (Inline), tie line (Crossline) directions and the intersection of the two directions with the same size grid, and convert them into interpretation files; Using the operation function in the interpretation platform, calculate the "frame line" in the Inline direction that has been converted into the interpretation format with the intersection (Eliminate where Z = suface(x,y)), obtaining the main survey line direction "frame line" excluding the intersection position data, as Figure 10 shown; According to the same method, exclude the intersection position data from the "frame line" in the tie line (Crossline) direction; Make a copy of the seismic horizon interpretation data, and perform an operation on one copy with the main survey line (Inline) direction "frame line" excluding the intersection position data (Eliminate where Z = suface(x,y)); According to the same method, perform an operation on the other copy of the previously copied seismic horizon interpretation data with the tie line (Crossline) direction "frame line" excluding the intersection position data (Eliminate where Z = suface(x,y)). Perform an interpolation operation on the two sets of seismic horizon interpretation data obtained above (Seismic operations - Interpolate empty); Perform an operation on the two sets of interpolated seismic horizon interpretation data with the previously created "intersection" interpretation file respectively (Eliminate where Z = suface(x,y)), obtaining two sets of seismic horizon interpretation data that only retain the intersection positions, see Figure 11; Subtract the two obtained seismic horizon interpretation data that only retain the intersection positions from each other (Arithmetic operations Z = Z – Surface(x,y)), and thus obtain the "height difference" of the intersection positions of the seismic horizon interpretation data line and the trace direction, as shown in Figure 12 .

[0147] Finally, convert the "height difference" of the intersection positions of the seismic horizon interpretation data line and the trace direction into a point file, and set the color display to "Z value (height difference) display". Further, by adjusting the color scale, the closed difference abnormal points can be highlighted by color, that is, the "jumping points" that are not closed in the T9 horizon interpretation (partial) of this work area, as Figure 13 shown.

[0148] As can be seen from the above description, the embodiment of the present invention provides a method for quality control of seismic horizon interpretation results, including: First, on the target seismic horizon interpretation result, establish a frame line through the intersection of the main survey line and the connecting survey line to generate a first frame line interpretation result; wherein, the frame line is two straight lines intersecting at the intersection point; then, perform time difference subtraction on the first frame line interpretation result and the seismic horizon interpretation result to generate a second frame line interpretation result; perform time difference subtraction on the seismic horizon interpretation result and the second frame line interpretation result to generate a third frame line interpretation result; finally, perform quality control on the target seismic horizon interpretation result according to the second frame line interpretation result and the third frame line interpretation result.

[0149] Whether the horizon interpretation data is closed is a key indicator for testing the accuracy of seismic data interpretation, and the closed difference calculation is an effective quality control method for seismic horizon tracking interpretation. The embodiment of the invention provides a method for quality control of seismic horizon interpretation results. Based on the calculation function of the mainstream interpretation software platform in the professional field, locate the intersection positions of the line and the trace direction and extract the horizon interpretation data at this point to obtain the closed differences in two directions, and then realize the visualization of the "jumping points" that are not closed at the intersection positions of the line and the trace direction in the horizon interpretation, improving the efficiency of seismic data horizon interpretation.
