Abstract

The invention provides a physical simulation method and device for salt rock stratum sealing performance after tectonic deformation and a medium. The method comprises the following steps of: executing tectonic deformation operation on an experimental model, and injecting oil; determining a data model according to the experimental model; determining the thickness of a salt rock layer, the overlying ground depth and oil injection distribution according to the data model; drawing a map of overlying ground pressure and the thickness of the salt rock layer according to the thickness of the salt rock layer and the depth of the overlying ground; marking the overlying ground pressure and salt rock layer thickness map according to the oil injection distribution, obtaining the sealing area, depicting the relation between the oil injection distribution and the overlying ground pressure and the relation between the oil injection distribution and the salt rock layer thickness quantitatively, and obtaining the area related to the salt rock layer sealing performance through the quantitative relation; and guiding actual oil and gas reservoir exploitation through the sealing area, and therefore, the probability of successful exploitation is greatly increased.

Description

technical field [0001] The invention relates to the technical field of earth geography and can be applied to oil and gas exploration, in particular to a physical simulation method, device and medium for the sealing performance of salt rock layers after structural deformation. Background technique [0002] Salt structure basins are widely distributed in North America, Central Asia, Africa, Europe, Southeast Asia and other regions. With the continuous deepening of oil and gas exploration, the study of salt structure has become one of the hot issues in the study of the structure of oil and gas-bearing basins. The continuous growth of oil and gas demand has stimulated the The study of salt formation. [0003] The development process of salt structures and the law of spatial variation directly affect the sealing performance of salt structures as cap rocks. According to statistics, only 46% of salt structures can achieve sealing performance as cap rocks, and can form reservoirs an...
