Research on prediction model and numerical simulation of reservoir rock mechanical parameters based on remote sensing images

摘要

The mechanical parameters of rock are the basic data for petroleum excavation, crushing engineering design, structural stress field calculation, and crushing prediction. The characteristics of Iwata are closely related to the development of many projects. In the development of the storage layer, the mechanical properties of the rock in the storage layer directly affect the parameter design of the hydraulic crushing scheme and the recovery rate of the oil and gas crushed on site. There are also great researches on the fine slice crushing technology and water injection. Restriction, technically, it is especially important that the mechanical parameters of the stored rock are the correct calibration method. This paper is based on the typical hydraulic fracturing engineering of sandstone storage layers in specific areas. Based on the physical and mechanical test data and geological logging data of the core samples, the relationship between the mechanical parameters and the microporous structure of the compact sandstone storage layer was studied from two aspects, physical and mechanical tests and numerical simulation tests, and the overall regression was studied. The analysis of physical and mechanical test data and numerical test data is carried out using statistical methods, and the mechanical parameter prediction model of the porous compact sandstone storage layer as the main variable is obtained, and then the mechanical parameters of the storage rock with different target depths are obtained as the verification prediction model The rationality of the three-dimensional stratum hydraulic crushing model was established.
