Description

TECHNICAL FIELD

[0001] The present application relates to the field of petroleum seismic exploration, and particularly relates to a three-dimensional visualization method and system for seismic data acquisition optimization excitation lithology well depth design. BACKGROUND

[0002] The excitation well depth design of seismic data acquisition is established on the basis of surface structure investigation mainly by micro-logging, and the velocity stratification from shallow to deep and core change of the surface shallow layer are understood by micro-logging, and then the surface high-speed layer is selected for excitation or excitation below the water table. In most areas such as mountains, hills, deserts, the surface sedimentary sequence is relatively stable, and the lithology of the high-speed layer is basically single and does not change, while the surface sedimentary sequence (lithofacies change) of the plain water network or saline-alkali area is complex, with the characteristics of repeated occurrence in the vertical direction and change in the horizontal direction, which is mainly caused by the alluvial deposition of the Quaternary system. The velocity of the surface structure is usually controlled by the phreatic surface, and the phreatic surface is the top interface of the high-speed layer. The complex and variable lithology layer below the phreatic surface is actually the same high-speed layer velocity, which cannot be distinguished by velocity (as shown in Figure 1 ).

[0003] Figure 1 It is shown that the conventional well depth design uses the conventional 7m below the phreatic surface, which can ensure the excitation effect of the entire work area. However, when there is extensive clay deposition in the surface layer of the work area, the excitation effect of clay excitation is usually better than that of fixed 7m below the phreatic surface. From the perspective of the best excitation effect, clay excitation should be selected. Since the clay is the result of the alluvial deposition of the Quaternary system in the surface layer, as shown in Figure 2 , the change of the clay in the vertical and horizontal directions is large, Figure 3 , and the conditions to be met for selecting clay excitation are more, so the realization of selecting clay excitation is a complex process.

[0004] Figure 4 , Figure 5 shows the method for designing well depth for clay in the past. Different isopachous surfaces are taken to judge the distribution of clay by horizontal plane slicing, whether there is clay (red) between the micro-logging at the isopachous surface, and the method ignores the influence of the surface elevation. The clay distribution between the micro-logging is interpolated by the sufr software, and it is inevitable that the boundary of the clay is not clear. As shown in Figure 4 , it can be seen that whether there is clay between the micro-logging needs many slices, and the well depth design is complicated, Figure 5 , and it is difficult to judge the boundary of the clay.

[0005] It can be seen that the previous seismic acquisition data cannot meet the needs of oil and gas development, and most exploration areas are arranging for the second or even third seismic data reacquisition. The current seismic data acquisition method gradually develops in the direction of high density, hoping that the signal-to-noise ratio and resolution of single shot data are improved compared with previous data. The previous only considering the excitation layer velocity cannot meet the needs of the excitation well depth design, and it is necessary to consider the excitation velocity layer in more detail on the basis of the excitation velocity layer, and excite in the best excitation lithology.

[0006] In addition, the existing two-dimensional vertical plane cement interpolation method cannot overcome the influence of the surface height difference, resulting in errors in the position of the cement; the boundary of the cement interpolation of the horizontal two-dimensional depth slice is not clear, resulting in inaccurate plane distribution of the cement. Moreover, the previous cannot carry out three-dimensional visualization scene interactive design, resulting in long design period and low efficiency. SUMMARY

[0007] The present application is aimed at the defects in the prior art that the well depth design in the cement layer is complicated, and the well depth design is prone to deviation, and provides a three-dimensional visualization method and system for seismic data acquisition and optimal cement excitation, which is simple to design and can accurately position.

[0052] In order to make the purpose, technical scheme and advantages of the present application more clear, the present application will be further described in detail below in combination with the drawings and examples. It should be understood that the specific examples described herein are only used to explain the present application, and are not used to limit the present application.

[0053] The three-dimensional visualization method for optimizing mud stimulation of the seismic data acquisition of the embodiment of the present application comprises the following steps:

[0054] S1, according to the imported each micro-logging borehole core data, the core is classified according to the standard stratigraphic attribute, and the initial surface lithology model is constructed according to the geological horizontal layer modeling technology;

[0055] S2, the aerial oblique photography data is loaded in the initial surface lithology model, the elevation of the initial surface lithology model is corrected to obtain a high-precision surface elevation lithology model, and the high-precision surface elevation lithology model and the surface image are fused to obtain a surface lithology fusion model;

[0056] S3, in the high-precision surface lithology surface lithology fusion model, one of the clay layers is selected as the excited lithology;

[0057] S4, in the surface lithology fusion model, one of the clay layers is selected as the excited layer, and the surface position of the excited point is determined, the depth position of the excited point is observed through the three-dimensional view of the surface lithology fusion model, if the depth position of the excited point is not in the selected clay layer, the depth position of the excited point is adjusted until the requirement is met.

[0058] In step S4, the bottom projection point of the excited well is observed through the forward top view and the reverse overhead view of the surface lithology fusion model, if the bottom projection point of the excited well cannot be seen in the selected clay layer in the two views, it indicates that the depth of the excited point is in the selected clay layer, and the depth of the excited well does not need to be adjusted.

[0059] If the projection point of the excited well is seen on the selected clay layer in the forward top view, the depth of the excited well needs to be deepened.

[0060] If the projection point of the excited well is seen on the selected clay layer in the reverse overhead view, the depth of the excited well needs to be reduced.

[0061] Further, if there are multiple clay layers in the surface lithology fusion model, one of the clay layers meeting the requirements of the excited well depth is selected.

[0062] Further, the method of the application further comprises the following steps:

[0063] S5, the best excited point position is selected from the adjusted excited point position, which meets the requirements of the excited well depth and lithology.

[0064] In another embodiment of the application, the fusion modeling can be realized by the following steps:

[0065] (1) three-dimensional lithology modeling of surface core investigation

[0066] For example Figure 6 The data of each micro-logging borehole core investigation is imported, and then the core is classified according to the standard stratigraphic attribute{x i , y j, (lithology 1, lithology 2, lithology 3,...)}, according to the horizontal layer modeling technique of geological modeling, a surface lithology model (such as Figure 7 、 Figure 8 , Figure 8 is a surface lithology modeling model of Figure 2 , from Figure 8 it can be seen that the model is suitable for geological sedimentary characteristics, can have geological phenomena such as lens and pinchout, and the contact relationship of the stratum is clear, which has never been done before and cannot be done.

[0067] (2) Realize the fusion of the surface image model and the lithology model

[0068] The drilling data in the surface lithology modeling model and the DEM data (aerial oblique photography data) are matched, and the DEM data can be used for interpolation, so as to obtain a high-precision surface elevation model. On this basis, the geological body is constructed from top to bottom, as shown in Figure 9 .

[0069] (3) Realize the three-dimensional visualization of the optimization design of the stimulated well depth lithology

[0070] The surface elevation difference in the plain water network area is between 2-5m. In the past, the well depth was designed by using the same elevation reference surface as Figure 10 , and since the thickness of the cement is not uniform, the slight surface elevation difference will affect the design precision of the well depth, and it is impossible to guarantee the purpose of cement stimulation. Therefore, in Figure 4 , before the plane interpolation of the cement distribution at different horizontal red lines, the influence of the surface elevation change on the elevation of the micrologging cement layer should be considered, and tedious elevation correction should be performed, such as the elevation correction effect shown in Figure 11 . In addition, the plane diagram obtained by the interpolation method in the past, such as Figure 5 , also has the problem of unclear lithology boundary, which indicates that the interpolation method in the past does not have the ability to optimize the cement stimulation design, not to mention ignoring the surface elevation difference. Generally, the micrologging well depth is about 30m, and the production well is about 15m, Figure 11 shows the position and depth relationship between the micrologging and the designed production well, and the depth of the micrologging and the designed well is different.

[0071] Since the geological model has the characteristics of one-time fast modeling, the influence of the surface elevation change (which is determined by the way of geological modeling), and the reasonable and clear description of the cement boundary, on the basis of the model, the optimization of the stimulated lithology can be realized.

[0072] On the basis of the above, the steps of the three-dimensional visualization method for the optimization of the cement stimulation of the seismic data acquisition of the preferred embodiment of the present application are as follows:

[0073] First, according to the coordinate range of the project (work area), the micrologging lithology column chart of the surface structure survey point is imported {xi , y j , (lithology 1, lithology 2, lithology 3, …), then the lithology horizontal layer interpolation method can be used to establish a geological lithology model, and then load the surface image map. The effect of this "surface lithology + surface image" three-dimensional fusion model is shown in the left of Figure 12 The different colors on the right side of the figure represent the geological layers from top to bottom as follows: 1 sand, 2 clay (yellow), 3 fine sand, 4 silt, 5 clay, 6 silt, 7 fine sand, 8 clay, 9 fine sand, and 10 clay.

[0074] Secondly, the model explosion analysis method (pulling apart the interval distance in x, y, and z directions) is used to establish the surface lithology - excited lithology (clay), as shown in the right of Figure 12 The figure shows 4 layers of deposited clay, and the yellow clay layer of the first layer is the target preferred layer. The other 3 layers of clay (the 3 layers of clay below the yellow clay layer) are not considered because the depth exceeds the design requirements of the well depth.

[0075] Figure 12 The red column in the middle of the right represents the lithology change encountered by a micro-logging drilling well with a depth of 30 m.

[0076] Figure 13 is a two-dimensional broken line lithology profile section of the three-dimensional surface lithology fusion model (i.e., high-precision surface lithology model + surface image model). This figure can flexibly cut and display the lateral variation of the lithology at the concerned position, and is used to analyze the data quality variation difference of different excited points on the broken line path.

[0077] Figure 14 The left is a well depth design and explosion analysis diagram of the three-dimensional surface lithology fusion model. The red column on the left is the lithology distribution drilled by all the designed excited points, Figure 14 The explosion analysis on the right shows that some wells are excited by sand, some by clay, and some by fine sand.

[0078] Figure 15 is based on Figure 14 The right, which hides and does not display non-clay lithology, separately displays the position distribution of the clay layer. The red column shows the lithology corresponding to the well depth of the excited test well at the position. The position of the subterranean water surface under the surface shows that the excited points of the test points are all below the subterranean water surface.

[0079] Figure 16 is a comparison diagram of the excited effects of different well depths and different excited lithologies. The figure shows that the reflection of the excited clay has the best continuity and signal-to-noise ratio.

[0080] Figure 17is the projection of the well bottom designed for 5m well depth under the water table on the front and back of the cement layer. From the figure, we can see that the drilling enters the cement, and there is no projection point (red dot) on the upper and lower surfaces of the cement layer for the designed well bottom that does not break through the cement layer; the well bottom that does not drill into the cement will have a projection point (red dot) on the upper surface of the cement, which needs to increase the well depth design; the well bottom that drills through the cement will have a projection point (red dot) on the lower surface of the cement, which needs to reduce the well depth design.

[0081] Figure 18 is the projection of the well bottom designed for the cement layer on the front and back of the cement layer. After adjusting the design well depth, the drilling depth points are all in the cement layer, and there are no projection points on the upper and lower surfaces of the cement layer.

[0082] Figure 19 Only the first layer of yellow cement (depth is designed in the left and right of the well depth, and the depths of the second and third layers of cement below are too deep and are not considered) is shown to facilitate the adjustment of well depth design and make the visualization target clearer.

[0083] Figure 20 The cement position display shows part of the western and southern areas of the work area, where there is no cement. From the overhead view, the upper surface of the cement layer has no red dot display, indicating that the drilling has drilled into the cement layer.

[0084] Figure 21 is the overhead image distribution of the drilling depth points on the bottom of the cement. From the display of the red projection point of the well site, most of the drilling has drilled through the cement, and there is no red projection point in the four red circles. That is, the designed well depth is only in the yellow cement of the four red circle points. Therefore, when designing, the points outside the four circles need to be adjusted to reduce the designed well depth, and the method of Figure 20 、 Figure 21 is used for three-dimensional visualization.

[0085] Figure 22 is the fusion well depth design model of the surface image, velocity model and lithology model. From the figure, we can see the position relationship between the depth of the excitation point under the high-speed layer top interface (water table) and the yellow cement. The red circled position (one of the four circles) is the best well depth position, which meets the double optimization (depth optimization, lithology optimization) excitation point position, meets the requirement of finding the cement layer under the water table, and can obtain better acquisition data than the conventional well depth design under the water table.

[0086] As Figure 23The prior cement excitation design method is compared with the cement optimization excitation design method. The present application realizes the visual cement layer optimization excitation design, brings the spatial on-the-spot feeling to the seismic data acquisition well depth design, improves the design efficiency and design precision of the target lithology excitation, and enriches the evaluation and analysis means of the single shot quality of the seismic acquisition. Especially in the gently-structured basin terrain, the fourth system alluvial deposit area, the present application can be used to excite the selected cement or other favorable lithology, so as to further improve the data quality.

[0087] The three-dimensional visualization system for the preferred cement excitation of the seismic data acquisition of the present application embodiment is mainly used for realizing the above-mentioned method embodiment, and the system mainly comprises:

[0088] An initial surface lithology model construction module is used for classifying the core according to the imported various micro-logging borehole core data, and constructing an initial surface lithology model according to the geological horizontal layer modeling technology;

[0089] A surface lithology fusion model construction module is used for loading the aerial oblique photography data in the initial surface lithology model, correcting the elevation of the initial surface lithology model to obtain a high-precision surface elevation lithology model, and connecting the initial surface lithology model and the surface image elevation without difference to obtain a surface lithology fusion model;

[0090] A three-dimensional visualization excitation point setting module is used for selecting a cement layer to design the excitation well depth in the surface lithology fusion model or the high-precision surface elevation model, and determining the excitation point position, observing the position of the excitation point through the three-dimensional view of the surface lithology fusion model or the high-precision surface elevation lithology model, and adjusting the excitation point position until the requirement is met if the excitation point position is not in the selected cement layer.

[0091] The three-dimensional visualization excitation point setting module specifically observes the projection point of the excitation well through the forward top view and the reverse overhead view of the surface lithology fusion model or the high-precision surface elevation lithology model, and if the well bottom projection point of the excitation well cannot be seen in the selected cement layer in the two views, it is indicated that the excitation point is in the selected cement layer, and the excitation well depth does not need to be adjusted.

[0092] If the well bottom projection point of the excitation well is seen in the selected cement layer in the forward top view, the depth of the excitation well needs to be deepened.

[0093] According to the above technical solution, if the well bottom projection point of the excitation well is seen in the selected cement layer in the reverse overhead view, the depth of the excitation well needs to be reduced.

[0094] If there are multiple cement layers in the initial surface lithology model, one cement layer meeting the excitation well depth requirement is selected.

[0095] The application further provides a computer readable storage medium, such as a flash memory, a hard disk, a multimedia card, a card memory (for example, an SD or DX memory, etc.), a random access memory (RAM), a static random access memory (SRAM), a read-only memory (ROM), an electrically erasable programmable read-only memory (EEPROM), a programmable read-only memory (PROM), a magnetic memory, a magnetic disk, an optical disk, a server, an App application store, and the like, which stores a computer program, and the program is executed by a processor to realize corresponding functions. The computer readable storage medium of the embodiment is used to realize the three-dimensional visualization method of the seismic data acquisition and optimized mud excitation when executed by the processor.

[0096] In summary, the application performs attribute unified calibration according to drilling core data of surface structure investigation; shallow surface geological model is established by using horizontal stratum modeling technology; the fusion model of "image + surface lithology" is established based on surface image data, the model has surface data, overcomes the influence of surface elevation, and can quickly realize well depth design; the projection technology of drilling on the upper and lower surfaces of the target mud layer is adopted, whether the designed well depth excitation point is in the mud layer can be quickly checked, so as to improve the design efficiency and design accuracy.
