Magmatic diapiric and extensional effect superimposed simulation device and analysis method

Abstract

The invention discloses a magmatic diapiric and extensional effect superimposed simulation device and analysis method, and belongs to the field of fault formation mechanism study. The magmatic diapiric and extensional effect superimposed simulation analysis method comprises the following steps of immersing a medium filled in a medium container into a sand box containing multiple layers of sand; then, starting a first engine and a second engine to stretch the sand box; cutting sand bodies to obtain a first slice; firstly starting the first engine and the second engine to stretch the sand box filled with the multiple layers of sand; then immersing the medium filled in the medium container into the sand box; cutting the sand bodies to obtain a second slice; obtaining a plurality of typical structure deformation styles according to the first slice and the second slice; comparing the typical structure deformation styles with a structure deformation style of a target region; and if the structure deformation style of the target region is similar to any one or a plurality of features in the typical structure deformation styles, determining the formation types of the structure deformation of the target region and the typical structure deformation styles. The seismic interpretation of the target region is favorably guided.

Description

technical field [0001] The invention relates to the field of fault genetic mechanism research, in particular to a simulation device and analysis method for superposition of magma diapir and extension. Background technique [0002] As a manifestation of magmatic activity, magmatic diapir is an important internal dynamic geological process. The magmatic activity is closely related to the formation and evolution of the basin, which plays an important role in controlling the generation and expulsion of hydrocarbon source rocks, the formation of traps, and the accumulation of oil and gas. Therefore, it is of great significance to study the relationship between magma diapirs and basin extension for oil and gas exploration and development. [0003] At present, a device for diapir structure research in oil and gas exploration is disclosed (Chinese patent application with publication number CN200965572Y), which provides a structural physical simulation test diapir device capable of ...

Problems solved by technology

[0004] However, there is no relevant device or method for exploring the combination pattern of structural deformation by taking the superposition of magma diapirism and extension as the cause of fault structure style, and the cause of some existing fault structure styles cannot be explained, and the development style cannot be explained. predict
