Embodiment Construction
[0016] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention. Additionally, the protection scope of the present invention should not be limited only to the following specific structures or components or specific parameters.
[0017] Both the foreland basin and the delta gravity-sliding structure contain a large amount of oil and natural gas. The structural evolution of the basin controls the deposition and later reformation of the strata, and the fault tectonic activity controls the deposition and burial of so...

The invention provides a sandbox physical simulation experiment equipment with plastic deformation structural feature under an analog overpressured formations migration condition, and the experiment equipment comprises a model module and a formation overpressure load module; the model module is used for placing an analog basin structure of dry quartz sand with 20 mesh in particle size and dry quartz sand with 40 mesh in particle size, wherein the dry quartz sand with 20 mesh in particle size is used to simulated form normal formation pressure stratum, and the dry quartz sand with 40 mesh in particle size is used to simulated form abnormal formation pressure stratum; the placing range of the dry quartz sand with 40 mesh in particle size is used to form the distribution range of abnormal formation pressure stratum, and dry quartz sand with 40 mesh in particle size is placed according to the realistic simulation experiment purpose; the formation overpressure load module is used for injecting air in the sand body model, the abnormal overpressure is formed in the dry quartz sand with 40 mesh in particle size based on the permeability difference between the dry quartz sand with 20 mesh in particle size and the dry quartz sand with 40 mesh in particle size. The sandbox physical simulation experiment equipment realizes the basin structure simulation of overpressure stratum plastic deformation.
Description
technical field [0001] The technical field of geophysical exploration of the present invention relates to a sandbox physical simulation experiment device for seismic exploration, in particular to a sandbox physical simulation experiment device for simulating the characteristics of plastic deformation structures under the condition of overpressure formation migration. Background technique [0002] Determined by the unique kinematics and dynamics characteristics of the shear wave, it has high resolution and penetration for complex formations with gravel and pebble layers and Quaternary natural gas reservoirs, and is often used in engineering seismic exploration. It better reflects the geological-geophysical characterization of the exploration site. Conventionally used vibrator guns, vibrators, and manpower vibrators have their own advantages and disadvantages. For example, the vibrator gun has a large excitation energy, but it is not safe and the use environment is limited; th...
