Abstract

Abstract

The rock mechanical stratigraphy controls the development degree and genetic mechanism of natural fractures. Similarly, the development of fractures also affects the size and anisotropy of rock mechanical parameters. Affected by diagenesis and tectonics, the rock mechanics layer has migrated. Therefore, the rock mechanics layer that controls the development of fractures and the rock mechanics layer suitable for predicting the distribution of natural fractures may no longer exist. This paper proposes a method based on reservoir geomechanics modeling to analyze the evolution of rock mechanics layer under the control of structural factors. A three-dimensional fracture discrete network model was established through field observations, combined with rock mechanics experiments to determine the mechanical parameters of the rock and fracture surfaces, the method for determining the optimal representation unit size of the fractured reservoir mechanical parameters was determined, and the three-dimensional geomechanical model of the fractured reservoir was established. A three-cycle method is proposed to characterize the equivalent mechanical parameters of fractured reservoirs with different sizes and different orientations. The Young's modulus discriminant index and Poisson's ratio discriminant index are used to characterize the scale effect and anisotropy of the mechanical parameters of fractured reservoirs, and the evolution of rock mechanics layer is analyzed. The results show that the fracture combination pattern on the western edge of Ordos basin and the accuracy requirements of the later stress field simulation determine the optimal element size for geomechanical modeling to be 28 m. In geomechanical modeling, too small grid element scale can not completely describe the fracture development mode in the element. The development of natural fractures from the Yanshanian period to the Himalayan period to the present has resulted in an overall decrease in the equivalent Young's modulus and an overall increase in the Poisson's ratio of the rock mass in the Ordos Basin. The difference between the equivalent Young's modulus and the Poisson's ratio of the rock mass has decreased over time.
