Experimental device and method for simulating formation and evolution process of oil reservoir

Abstract

The invention relates to an experimental device and method for simulating a formation and evolution process of an oil reservoir. The experimental device for simulating the formation and evolution process of the oil reservoir comprises an experimental cabinet body, a placement cabinet body and a control system, wherein three movable test tables are arranged in the test cabinet side by side, each square table is provided with a geologic structure simulation box, glass observation windows are arranged at the positions, corresponding to the three geologic structure simulation boxes, of the test cabinet, three three-way combination valves are arranged on a front panel of the test cabinet, and each three-way combination valve is connected with a corresponding geological structure simulation box; a bottom plate of the geologic structure simulation box is formed by splicing two aluminum alloy plates side by side, two electric push rods are fixed to the outer sides of the two aluminum alloy plates, the electric push rods are slidably connected with the sliding ways, and a geologic model is laid on the bottom plate; the placement cabinet body is arranged in front of the experiment cabinet body, and a high-pressure liquid injection system and a control system are arranged in the placement cabinet body. According to the method, the influence of later-stage structural activity and multi-stage charging on oil and gas accumulation is effectively reflected.

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...

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.
