Description

Technical Field

[0001] The present invention relates to the technical field of oil exploration and development, and particularly to a method, device, electronic device and storage medium for seismic horizon interpretation and verification. Background Art

[0002] Seismic horizon interpretation is a key technology in seismic exploration. Usually, it is important basic data for geological work such as drawing stratigraphic structure maps, thickness maps, paleogeomorphic restoration, and seismic attribute extraction, etc. It involves a method of tracing and interpreting the target horizon on the seismic data volume according to the seismic reflection characteristics of the target horizon to obtain seismic horizon data. During the process of seismic horizon interpretation, information such as the amplitude, phase, morphology, continuity, and characteristic combination of seismic signals is mainly concerned. This technology is particularly important for oil and gas exploration and development, and is a way to study the geology of underground reservoirs using seismic data, because its accuracy directly affects the rationality of underground reservoir interpretation.

[0003] Seismic horizon correction is even one of the important tasks in seismic horizon interpretation, and the accuracy of its results directly affects the understanding of subsequent strata, structures, and reservoirs, etc. The current horizon correction mainly relies on the layered data in wells for well-seismic calibration to correct the accuracy of seismic horizons, but it has a high requirement for well pattern density. In the case of low well pattern density, this correction method is difficult to make full use of seismic information. Its accuracy is better in the cross-well profile, but it is difficult to grasp the accuracy in the inter-well area. Therefore, a method that can perform correctness analysis in space is needed.

[0004] Seismic horizon flattening is a commonly used method to verify whether it is correct, but it mostly uses a single profile for verification. Therefore, it cannot analyze the correctness of the seismic interface in space. After projecting it into three-dimensional space, although the three-dimensional display technology can identify the similarity of a single layer, it is difficult to analyze the transformation relationship between horizons, and it cannot verify the rationality of the seismic horizon interpretation in space. Summary of the Invention

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the present invention.

[0019] In the description of the embodiments of the present invention, unless otherwise specified, the meaning of "a plurality" is two or more. "And / or" describes the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist simultaneously, and B exists alone.

[0020] The descriptions such as "first" and "second" involved in the embodiments of the present invention are only for descriptive purposes, and cannot be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features. Therefore, the technical features defined with "first" and "second" may explicitly or implicitly include at least one such feature.

[0021] Referring to "embodiments" herein means that the specific features, structures, or characteristics described in connection with the embodiments can be included in at least one embodiment of the present invention. The phrase appears in various places in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0022] Before presenting the embodiments, the following terms are explained first: Well: Refers to a drilling well, which is a vertical or inclined underground passage drilled for purposes such as geological exploration, oil and gas extraction, or scientific research.

[0023] Layer flattening analysis method: By flattening the seismic data volume along the seismic reflection horizon corresponding to a specific geological boundary, the paleogeomorphology in the geological history period is restored, and then the paleostructure, paleosedimentary characteristics, and geological evolution process of the underlying strata are examined.

[0024] Connected well section: Refers to a continuous geological cross-section formed by comprehensively analyzing the geological data (such as lithology, formation thickness, fossil data, etc.) of multiple wells. It can intuitively display the continuity of strata at different depths underground, helping geologists better understand the structure and distribution of underground strata.

[0025] Gyration contrast: Based on core and logging information, controlled by stratigraphic correlation marker beds and the spatial evolution law of sedimentary facies, comprehensively considering factors such as the self-gyration characteristics of strata, sedimentary microfacies combinations, and sand body configuration relationships, contrast the boundaries of high-order genetic stratigraphic units, analyze the relationship between the spatial distribution of genetic stratigraphic units and the evolution law of sedimentary facies, and improve the results of stratigraphic isochronous correlation.

[0026] Reflection signal: It is the energy record of the seismic wave reflected by the underground stratigraphic interface and is the key information carrier for revealing underground structures and lithological characteristics.

[0027] Seismic interface: Refers to the interface in the underground medium layer that can reflect or refract artificial seismic waves, usually the wave impedance interface or velocity interface.

[0028] Seismic horizon tracking: It is the core link in seismic data interpretation, mainly used to identify the in-phase axis in seismic data (i.e., the reflection signal of the stratigraphic interface), so as to infer the underground geological structure and reservoir distribution.

[0029] The present invention provides a seismic horizon interpretation verification method, a photovoltaic cabin power supply system, and a control method, which will be described separately below.

[0030] Figure 1 It is a schematic flow chart of an embodiment of the seismic horizon interpretation verification method provided by the present invention. As Figure 1 shown, the seismic horizon interpretation verification method includes: S101. Establish a number of seismic correlation profiles passing through the central well point based on a preset central well point and several standard well points.

[0031] It should be noted that when selecting the central well point and standard well points, representative well points in the study area should be selected as the central well point based on regional geological understanding. Because the selected central well point is representative and has a standard role in the stratigraphic division of this area, the stratigraphic division result is the most accurate. After determining the central well, look for standard wells in all directions of the study area to provide support for the next step.

[0032] Furthermore, the method steps of the present invention are all carried out in the Petrel software, and modeling and analysis are carried out in Petrel to more intuitively analyze the spatial correlation of seismic horizons.

[0033] In order to improve the spatial rationality of the final seismic horizon interpretation result, as many and representative original samples as possible need to be obtained. For example Figure 2 , in some embodiments of the present invention, step S101 specifically includes: S201. Construct a well connection profile between the central well point and several standard well points; S202. Based on the cross-well profile, with the central well point as the center, several seismic correlation profiles are constructed at preset angular intervals.

[0034] Preferably, with the central well point as the center and at an angular interval of 30°, the common midpoint radial seismic correlation profiles as shown in Figure 3 are obtained.

[0035] S102. Perform well-seismic calibration on several seismic correlation profiles.

[0036] To further improve the accuracy of seismic horizon tracking, as shown in Figure 4 , in some embodiments of the present invention, step S102 includes: S401. Divide the formation of the standard well points on the seismic correlation profiles.

[0037] Specifically, based on the principle of formation correlation and with a preset marker bed as the basis, the formation of the standard well is divided by the method of cycle correlation.

[0038] S402. Successively perform synthetic seismic records and time-depth conversion on the standard well points after the formation division to obtain the positions of the formations of each standard well on the seismic interface.

[0039] S103. Perform seismic horizon tracking on several seismic correlation profiles based on the reflection characteristics of the seismic correlation profiles and the results of well-seismic calibration, and continuously roll and flatten all the tracked seismic horizons on the seismic correlation profiles, and correct the seismic horizons based on the change trend between the upper and lower horizons of the flattened seismic horizons.

[0040] As shown in Figure 5 , in some embodiments of the present invention, step S103 includes: S501. For any seismic correlation profile, determine the formation framework division scheme based on the corresponding reflection characteristics.

[0041] Specifically, by comparing the reflection characteristics of the seismic profile, a formation framework division scheme is formed. Taking Figure 6 as an example, the characteristics of the second-order sequence interfaces on the seismic profile are obvious, all being strong amplitude and continuous reflections, with truncation, downlap and other reflection characteristics in local areas. The formations inside the second-order sequence interfaces are mostly medium-strong reflections or weak reflections, with poor continuity.

[0042] S502. Perform seismic horizon tracking on the seismic correlation profile based on the formation framework division scheme and the results of well-seismic calibration; S503. Layer by layer, flatten the seismic horizons of the seismic correlation profile; S504. If the flattened seismic horizon and the upper and lower horizons of the seismic horizon thicken and diverge or converge and thin together, it is determined that the seismic horizon tracking of the seismic correlation profile is correct and the next step is entered; otherwise, the seismic horizon tracking is performed again. S505. Perform seismic horizon tracking on other seismic correlation profiles except the above-mentioned seismic correlation profile based on a preset line spacing. Specifically, starting from the central well point and using the stratification points on the radiating profile as the starting points, seismic horizon division and comparison are carried out along the connecting lines of the main lines at a certain line spacing.

[0043] It should be noted that in this embodiment, it is confirmed whether the interpretation of the seismic horizons tracked by the present invention is correct. If it is feasible, it means that other profiles are comparable to the sample profile in terms of correctness. Therefore, only by flattening layer by layer according to the line spacing, the same calibration accuracy can be achieved with less workload.

[0044] S506. Flatten the seismic horizons of other seismic correlation profiles layer by layer and surface by surface. S507. If the flattened seismic horizon and the upper and lower horizons of the seismic horizon thicken and diverge or converge and thin together, it is determined that the seismic horizon tracking of the seismic correlation profile is correct; otherwise, the seismic horizon tracking is performed again.

[0045] It should be noted that for each seismic horizon interpreted by the radioactive seismic correlation profile, layer flattening analysis is carried out. Through layer flattening, the relationship between the upper and lower seismic reflection horizons will be found. It may occur that the upper and lower layers are parallel or thicken and diverge or converge and thin together after flattening. This generally indicates that the compared horizons are okay. If the upper and lower horizons show a consistent downward or upward convex trend, it is very likely that there is a problem with the horizons during comparison. The upward convexity may be due to the local horizon being tracked too low, and the downward concavity may be due to the tracked horizon being too high. At this time, adjustment is required.

[0046] Such as Figure 6 , in some embodiments of the present invention, step S502 includes: S601. Construct a formation framework on the seismic correlation profile based on the formation framework division scheme.

[0047] S602. Within the formation framework, perform seismic horizon tracking based on the positions of the formations of each standard well on the seismic interface.

[0048] It can be understood that in this embodiment, first, the large structure is divided on the seismic correlation profile through the formation framework division scheme, and then the seismic horizons are refined at each level of structure class according to the positions of the formations of each standard well on the seismic interface.

[0049] Through the above steps, the present invention has obtained a seismic horizon interpretation with high accuracy on a two-dimensional level. Further, these two-dimensional seismic horizon interpretations are transformed into three-dimensional seismic horizon interpretations to make them relevant in space, such as Figure 1 , the present invention further includes the following steps: S104. Project a number of seismic correlation profiles after seismic horizon correction into three-dimensional space and compare them with a preset seismic axis in the three-dimensional space. If there is no difference, it is confirmed that the verification is completed.

[0050] Specifically, for the three-dimensional seismic model obtained by projecting a number of seismic correlation profiles after correction into three-dimensional space, rolling comparison is performed in the main survey line direction and the tie line direction respectively based on the preset seismic axis. If there is no difference, the verification is completed.

[0051] Compared with the prior art, a seismic horizon interpretation verification method provided by the present invention is based on representative center points and standard points in a pre-selected work area. With the center point as the center, seismic correlation profiles are established through the center point according to a preset interval. Then, seismic horizon tracking is performed on the seismic correlation profiles, and the mutual relationship between the strata above and below the seismic horizon is checked by continuously rolling and flattening the tracked horizons to complete the verification of the seismic horizon interpretation. At the same time, by continuously rolling the seismic correlation profiles, the seismic horizons are adjusted so that the mutual relationship between the upper and lower strata conforms to geological understanding, and a two-dimensional profile with high accuracy is obtained. Finally, each two-dimensional profile is projected into three-dimensional space to obtain a three-dimensional seismic model with high accuracy, so as to be able to verify the rationality of each seismic horizon interpretation in space and form a seismic interpretation framework with geological significance, effectively solving the technical problem that the prior art cannot verify the rationality of seismic horizon interpretation in space.

[0052] Such as Figure 7 , on the second aspect, the present invention further provides a seismic horizon interpretation verification device 70, including: A profile establishment module 710, configured to establish a number of seismic correlation profiles passing through the center well point based on a preset center well point and a number of standard well points; A well-seismic calibration module 720, configured to perform well-seismic calibration on a number of seismic correlation profiles; A horizon flattening verification module 730, configured to perform seismic horizon tracking on a number of seismic correlation profiles based on the reflection characteristics of the seismic correlation profiles and the results of well-seismic calibration, and continuously roll and flatten all the tracked seismic horizons on the seismic correlation profiles, and correct the seismic horizons based on the change trend between the upper and lower horizons of the flattened seismic horizons; A three-dimensional verification module 740, configured to project a number of seismic correlation profiles after seismic horizon correction into three-dimensional space and compare them with a preset seismic axis in the three-dimensional space. If there is no difference, it is confirmed that the verification is completed.

[0054] It should be understood that: when the processor 820 executes the magnetic resonance image optimization program in the memory 810, in addition to the above functions, other functions can also be implemented. For details, reference can be made to the description of the corresponding method embodiments above.

[0055] Furthermore, the type of the electronic device 80 mentioned in the embodiments of the present invention is not specifically limited. The electronic device 80 may be a mobile phone, a tablet computer, a personal digital assistant (PDA), a wearable device, a laptop computer, or other portable electronic devices.

The above portable electronic devices may also be other portable electronic devices, such as a laptop computer with a touch-sensitive surface (such as a touch panel). It should also be understood that in some other embodiments of the present invention, the electronic device 80 may not be a portable electronic device, but a desktop computer with a touch-sensitive surface (such as a touch panel).

[0056] Fourthly, the present invention further provides a storage medium, comprising: For storing computer-readable programs or instructions, the programs or instructions can implement the steps in the seismic horizon interpretation verification method described in any one of the above method items when executed by a processor.

[0057] Those skilled in the art can understand that all or part of the processes for implementing the methods in the above embodiments can be completed by instructing relevant hardware (such as a processor, a controller, etc.) through a computer program.

Among them, the computer-readable storage medium is a magnetic disk, an optical disk, a read-only memory, or a random access memory, etc.

The description of the above embodiments is only used to help understand the method and its core idea of the present invention; at the same time, for those skilled in the art, according to the idea of the present invention, there will be changes in the specific implementation manner and application scope.
