Abstract

The invention relates to a sand box physical simulation experiment device and experiment method for simulating multi-direction extrusion deformation. The sand box physical simulation experiment devicefor simulating multi-direction extrusion deformation comprises a model mechanism, a driving mechanism, an image acquisition system and a computer control system, the driving mechanism is fixed on oneside of an experiment table bracket and provides power for a bottom plate to perform diving motion, and a rotating shaft is arranged on the other side of the experiment table; the model mechanism comprises the experiment table bracket, an experiment table, a sand box end coaming, a sand box side coaming, a sand scraping plate apparatus and a rotating disc. The driving mechanism is connected to the computer control system, and the rotating speed of a reel is controlled by the computer control system, and a sand box physical simulation experiment of two-dimensional or three-dimensional multi-stage displacement deformation field superposition with different migration speeds and different combination modes is carried out. The device and the method can realize the structure evolution process of simulating reactivation of compression pre-existing faults with different migration rates and different occurrences in a three-dimensional space without change of fault properties and inducing secondary fault formation.

Description

Technical field: [0001] The invention relates to a sandbox physical simulation experimental device for the evolution of internal fault activities in a medium-pressure petroliferous basin in the research fields of structural geology and petroleum geology, and specifically relates to a squeeze that is used to simulate the compression and deformation of an early pre-existing structure The physical simulation experiment device and method of the multi-directional squeeze-deformation sandbox are reactivated by the displacement and deformation field of different properties in the late structural superposition. Background technique: [0002] Compressive structural deformation is the basic way of crustal deformation, and compressive basin is one of the basic types of basins. As the compressive basins are subjected to different degrees of compression, there are compression structures, which makes it difficult for oil and gas exploration in the compression structure belt. For compressive p...
