This embodiment is applicable to the case of quantitative analysis of oil and gas accumulation based on a physical simulation experimental model of oil and gas accumulation. The method can be performed by a quantitative analysis device for oil and gas accumulation. The quantitative analysis device for oil and gas accumulation can be implemented in the form of hardware and / or software. The quantitative analysis device for oil and gas accumulation can be configured in an electronic device. Figure 1 As shown, the method includes:

[0031] S110. Physical simulation experimental model of structural oil and gas accumulation.

[0032] In this scheme, the physical simulation experimental model of oil and gas accumulation is widely used in the structural deformation of oil and gas sedimentary basins. It is an important method for quantitative analysis and evaluation of the formation and evolution of oil and gas structural closures.

[0033] Specifically, a physical simulation experimental model of oil and gas reservoir formation can be prefabricated in the experimental sand box. The commonly used materials for the physical simulation experimental model of oil and gas reservoir formation are loose materials and white oil. The cracking of loose materials under external stress conforms to the rock cracking criterion in nature and is often used to simulate the structural deformation of real underground oil and gas migration. Among them, materials with different densities represent different underground rock layers.

[0034] Optional, physical simulation experimental model for structural oil and gas accumulation, including:

[0035] According to the actual geological model, a physical simulation experimental model of oil and gas accumulation is constructed according to a predetermined similarity ratio, and filled with oil and gas to construct the final physical simulation experimental model of oil and gas accumulation.

[0036] In this embodiment, the actual geological model of the target area can be obtained through geological exploration technology.

[0037] Among them, the similarity ratio can be set according to the structural requirements of the oil and gas reservoir physical simulation experimental model.

[0038] Furthermore, according to the principle of structural physical simulation experiment of oil and gas accumulation, the actual geological model can be prefabricated into an oil and gas accumulation physical simulation experiment model in an experimental sand box according to a certain similarity ratio, and filled with oil and gas to construct the final oil and gas accumulation physical simulation experiment model.

[0039] By constructing a physical simulation experimental model for oil and gas accumulation, we can use industrial computer tomography technology and seismic imaging physical simulation technology to quantitatively analyze oil and gas accumulation in tectonic areas, thereby improving the accuracy of oil and gas accumulation analysis and making oil and gas exploration more precise.

[0040] Optionally, a physical simulation experimental model of oil and gas accumulation is constructed according to the actual geological model and a predetermined similarity ratio, including:

[0041] According to the actual geological model and the predetermined similarity ratio, a physical simulation experimental model of oil and gas accumulation is constructed based on quartz sand structures with different densities.

[0042] Among them, quartz sand is quartz particles made by crushing quartz stone. Quartz stone is a non-metallic mineral, a hard, wear-resistant, and chemically stable silicate mineral.

[0043] Specifically, according to the principle of structural physical simulation experiment of oil and gas accumulation, the actual geological model can be prefabricated into an oil and gas accumulation physical simulation experiment model composed of different quartz sands in an experimental sand box according to a certain similarity ratio, and then filled with oil and gas to construct the final oil and gas accumulation physical simulation experiment model.

[0044] By constructing a physical simulation experimental model for oil and gas accumulation, we can use industrial computer tomography technology and seismic imaging physical simulation technology to quantitatively analyze oil and gas accumulation in tectonic areas, thereby improving the accuracy of oil and gas accumulation analysis and making oil and gas exploration more precise.

[0045] Optionally, based on the actual geological model, a physical simulation experimental model for oil and gas accumulation is constructed according to a predetermined similarity ratio, which also includes:

[0046] According to the actual geological model, the boundary conditions of the oil and gas accumulation physical simulation experimental model are constructed according to a predetermined similarity ratio; wherein the boundary conditions include deformation rate and deformation amount.

[0048] By constructing a physical simulation experimental model for oil and gas accumulation, we can use industrial computer tomography technology and seismic imaging physical simulation technology to quantitatively analyze oil and gas accumulation in tectonic areas, thereby improving the accuracy of oil and gas accumulation analysis and making oil and gas exploration more precise.

[0049] S120, using industrial computer tomography technology to scan the oil and gas reservoir physical simulation experimental model to obtain a structural velocity model.

[0050] Among them, industrial computerized tomography (industrial CT) can scan and image the oil and gas migration conditions at different structural deformation stages of the physical simulation experimental model of oil and gas accumulation. Industrial CT has greater power and stronger penetration ability.

[0051] In this embodiment, there are differences in material density during the experiment. The propagation speed of ultrasound is different in materials of different densities. By scanning the physical simulation experimental model of oil and gas reservoir formation using industrial computer tomography technology, an accurate structural velocity model can be established.

[0052] Furthermore, in actual oil and gas exploration in complex structural areas, it is very difficult to establish an accurate structural velocity model due to the complex structural deformation, which increases the difficulty of later oil and gas reservoir exploration. Therefore, the accurate structural velocity model provided by the physical simulation experimental model of oil and gas accumulation can improve the quantitative analysis and evaluation of oil and gas accumulation in complex structural areas.

[0053] Optionally, the oil and gas reservoir physical simulation experimental model is scanned using industrial computer tomography technology to obtain a structural velocity model, including:

[0054] The structural deformation results and the acoustic wave propagation velocity of the oil and gas reservoir physical simulation experimental model are scanned by industrial computer tomography technology to obtain a structural velocity model.

[0055] Specifically, according to the actual geological conditions and research needs, the structural deformation results of the oil and gas accumulation physical simulation experimental model were scanned using industrial computer tomography technology at regular intervals during the experiment. At the same time, based on the speed at which ultrasonic waves propagate in different materials, a structural velocity model of structural deformation was established.

[0056] The physical simulation experimental model of oil and gas accumulation based on industrial computer tomography technology can accurately provide structural models and velocity models for different oil and gas migration stages, and provide model support for seismic imaging of complex structural belts.

[0057] S130, using seismic imaging physical simulation technology to process the oil and gas reservoir physical simulation experimental model to obtain seismic imaging.

[0058] Among them, the physical simulation of seismic imaging is based on the artificially established geological model. Ultrasonic waves are used in the laboratory to simulate artificial explosions in the field, collect and process the model reflection signals and form images, guide the actual seismic data processing and interpretation, and improve the quality of seismic imaging and the accuracy of interpretation.

[0059] In this scheme, since a wave impedance interface will be generated between different materials, the seismic imaging physical simulation technology can be used to collect the reflection signal of the oil and gas accumulation physical simulation experimental model of the oil and gas accumulation structure and perform seismic imaging.

[0060] Optionally, the oil and gas reservoir physical simulation experimental model is processed using seismic imaging physical simulation technology to obtain seismic imaging, including:

[0061] The seismic imaging physical simulation technology is used to collect and process the reflection signal of the oil and gas reservoir physical simulation experimental model to obtain seismic imaging.

[0062] Specifically, the seismic imaging physical simulation technology uses ultrasound to simulate artificial explosions in the field in the laboratory, collects and processes the reflected signals of the oil and gas accumulation physical simulation experimental model and images it to construct seismic imaging.

[0063] The seismic imaging physical simulation technology is used to collect and process the reflection signals of the oil and gas accumulation physical simulation experimental model to construct seismic imaging, which can guide the actual seismic data processing and interpretation and improve the quality of seismic imaging and interpretation accuracy.

[0064] S140, quantitatively analyzing oil and gas accumulation based on the structural velocity model and seismic imaging.

[0065] In this embodiment, quantitative analysis of oil and gas accumulation in complex structural areas based on structural velocity models and seismic imaging can improve geological understanding, reduce exploration risks, and make oil and gas exploration more accurate, which is of great significance to the advancement of oil and gas exploration technology in complex structural belts.
