Description

Technical Field

[0001] The present disclosure relates to the technical fields of earth science and petroleum industry, and particularly to a physical simulation experimental device for tectonic deformation. Background Art

[0002] Since the 19th century, the physical simulation experiment of the experimental sand box for tectonic deformation has been an important means to study complex tectonic deformation and its mechanism, and has been widely applied in the tectonic deformation of sedimentary basins containing oil and gas. It is also an important method for evaluating the formation and evolution of hydrocarbon-bearing tectonic traps and quantitative analysis. In the first half of the 20th century, more and more geologists used physical simulation experiments to study various geological problems. In the research on the process of tectonic physical simulation experiments, for the observation of the internal tectonic deformation of the model, scientists only sliced the model after solidification. The defect of this method is that it can only be implemented in the later stage of the experiment, but the internal tectonic deformation situation cannot be observed during the experiment. During the extrusion process of the physical simulation experiment, only visual observation can be carried out through the outer wall of the experimental sand box. However, due to the boundary effect of the side wall of the experimental sand box on the experiment, it will cause errors in the analysis of the experimental results. Applying computer tomography (CT) technology to the physical simulation experiment of tectonic deformation, due to its non-contact, non-destructive, high sensitivity, fast response speed, stable and reliable performance, etc., and being applicable to models such as high temperature, high pressure, and high humidity, we can successfully obtain the structural images at any position inside the experimental model at important stages during the experiment, and construct volume data later, which is of great significance for the exploration of oil and gas in deep and ultra-deep complex tectonic zones.

[0003] In order to solve the problems existing in the research on unconventional oil and gas exploration in basins and truly achieve the processual real-time monitoring of three-dimensional dynamic tectonic control of hydrocarbon accumulation, the previous physical simulation experiments of tectonic deformation could only be extruded first and then moved into the industrial CT for scanning. However, the commonly used materials in the experiment are loose materials, which will cause secondary deformation during the handling process. In order to reduce a series of derivative structures generated during the process of moving the experimental sand box in the experiment, which will have a greater impact on the experimental results.

Refer to Figure 1 As shown, the experimental box body 4 is generally a square box body, including 4 side plates. One of the side plates is the movable first side plate 10. The motors 2 are located at both ends of the second side plate 11, which can improve the compactness of the overall structure and reduce the occupied volume. Among them, the four side plates can enclose a square structure, and the height of each side plate is 15 cm and the length is 60 cm.

[0077] In some embodiments, the connecting plate 9 and the first side plate 10 are connected by a plurality of the connecting rods 6. Refer to Figure 1 As shown, the connecting plate 9 and the first side plate 10 are connected by two connecting rods 6, which can ensure the stability of the connection between the connecting plate 9 and the first side plate 10.

[0078] In addition, the physical simulation experimental device for structural deformation further includes a substrate 1 that supports the driving assembly and the experimental box body 4. The experimental box body 4 and the driving assembly can be arranged on the same substrate 1, which is convenient for synchronously moving into or out of the scanning instrument.
