Abstract

The invention discloses a discrete element-based cracked valley basin extension process simulation method, which gives a tough substrate construction method by fully considering geological characteristics of a stratum in a geological historical period, and establishes a discrete element model close to a cracked valley basin extension process. In the simulation process, the deposition or denudationprocess can be added, and the influence of the general geological phenomenon on the structural deformation of the area is researched. According to the method, a pre-existing fault does not need to beset, so that the model has a particle structure similar to a real rock mass. The discrete element simulation can supplement and replace a part of experiments, and the discrete element simulation-based structure evolution process and the structure deformation mechanism research method can obtain data which are not easy to measure in the experiments. The existing theory is improved to solve actualproblems, and theoretical support is provided for oil and gas exploration work of the cracked valley basin.

Description

technical field [0001] The invention belongs to the technical field of geological structure deformation simulation research, in particular to a discrete element-based rift basin extension process simulation method. Background technique [0002] Rift basins are formed under the background of tensional stress dynamics. Predecessors have done a lot of research on the dynamic models of the formation and evolution of rift basins, which is currently a hot spot in oil and gas exploration at home and abroad. It is necessary to explore the formation and evolution process of faults in rift basins under different geological conditions by means of experimental simulation. Moreover, existing studies have shown that basement lithology controls the structural development patterns in rift basins. In structural physical simulation, canvas is generally used to simulate rigid bases, and rubber sheets are used to simulate ductile bases by transferring tensile stress. [0003] Previous rift ba...
