Problems solved by technology
[0004] The purpose of the present invention is to provide an experimental device for simulating the formation and evolution process of oil reservoirs. This experimental device for simulating the formation and evolution process of oil reservoirs is used to solve the problem that the geological environment of the existing simulation experiment devices is relatively single and cannot be used in actual use. Another object of the present invention is to provide an experimental method for this experimental device for simulating the formation and evolution process of oil reservoirs to effectively reflect the impact of later tectonic activities and multi-stage charging on oil and gas accumulation.

Embodiment Construction
[0026] Below in conjunction with accompanying drawing, the present invention will be further described:
[0027] This experimental device for simulating the formation and evolution of reservoirs is an experimental device for simulating the formation and evolution of reservoirs under different geological conditions. flow, to observe the formation and evolution process of the reservoir. During the experiment, the silica gel and quartz sand were interlayered in the geological structure simulation box, and the electric push rod was controlled by the computer, and the deformation simulation of extrusion or tension was realized by two aluminum alloy plates; through the high-pressure liquid injection system, different oil tanks The internal oil is injected into the geological structure simulation box at a preset flow rate. During the experiment, the reservoir evolution process during the experiment can be observed through the glass observation window. After the experiment, the geol...

Description
1. Technical field: [0001] The invention relates to a physical simulation experiment device for the formation, adjustment and destruction process of oil reservoirs in sedimentary basins in the research fields of structural geology and petroleum geology, and specifically relates to an experimental device and method for simulating the formation and evolution process of oil reservoirs. 2. Background technology: [0002] In a sedimentary basin, the oil formed in source rocks will undergo primary migration and secondary migration through migration channels such as faults and transport layers, and finally fill into traps to form oil reservoirs. However, in the long geological process, after the formation of oil reservoirs, under the influence of complex geological activities, the existing oil reservoirs will often be adjusted, and new secondary oil reservoirs will be formed in shallow layers, while some of the reservoirs that have experienced intense tectonic activities Oil reserv...
