Experiment device used for simulating influences of various cause conditions on low-amplitude structural configuration

Abstract

The invention relates to an experiment device used for simulating the influences of various cause conditions on low-amplitude structural configuration in the technical field of geologic structures. The experiment device mainly comprises a computer system, a case body, a piston ring, a piston, a pressure pipe, sandstone particles, mudstone particles, a pressure feed ring, a bolt, an air compressor A, a high-speed camera, an iron prop, a pressure sensor, a small ball valve, a small pressure gauge, a large pressure gauge, a large ball valve, an air compressor B, a lower ground layer, a lateral substrate, an upper ground layer, and a reservoir stratum. The core of the technical scheme is that the actual condition of the underground stratum and the stress effects of differential compaction, basement uplift and lateral extrusion on the stratum in the formation of the low-amplitude structure are relatively truly simulated in the case body. The experiment device is simple in operation, and can well simulate the process of the influences of various cause conditions on the low-amplitude structural configuration.

Description

technical field [0001] The invention relates to an experimental device for simulating the influence of multiple genetic conditions on low-amplitude structural forms in the technical field of geological structures. Background technique [0002] The term low-amplitude structures is used to comprehensively describe these low-amplitude, highly concealed structures with different origins and scales and their combinations that are difficult to discover and identify with existing geophysical exploration methods. Low-amplitude structures generally develop in strata several thousand meters below ground level, which are often affected by various factors such as differential compaction, basement uplift, and horizontal compressive stress. As a result, various low-amplitude structures such as nose uplifts, domes, anticlines, and flexures have been produced; a large number of facts accumulated through years of field exploration have proved that low-amplitude structures play a role in cont...

Problems solved by technology

If the problem of the influence of various genetic conditions on the morphological characteristics of low-amplitude structures cannot be solved, it will directly lead to problems such as the difficulty in judging the scale and type of low-amplitude structures in geological exploration, and the difficulty in clarifying the law of oil and gas enrichment in related reservoirs. , resulting in deviations in the deployment of well locations in exploration operations, and ultimately lead to a large amount of exploration funds lost
