Problems solved by technology

The current reservoir fracture modeling technology, whether it is the equivalent simulation method or the physical fracture characterization method, does not consider the changing characteristics of the fracture during the development process. Due to the lack of research methods for the characterization of the dynamic fracture system formed by fractures and strain associated with it, the fitting workload and low fitting accuracy of a single well with the characteristics of rapid water breakthrough in fractures are large, which affects the accuracy of remaining oil description, and it is difficult to meet the requirements of low-permeability oil. The need for fine potential mining in the middle and later stages of Tibetan block development

Abstract

The invention relates to a permeability determination method and device, a characterization method and device, electronic equipment and a storage medium, and relates to the technical field of dynamic fracture geology, and the permeability determination method is applied to dynamic fracture geology and comprises the steps of obtaining the fracture opening degree of any position, away from the fracture center, on a dynamic fracture geology fracture; and determining the real-time dynamic fracture permeability of the fracture between the water well and the oil well in the water injection development process based on the fracture opening. According to the embodiment of the invention, the real-time dynamic measurement of the fracture permeability of the fracture between the water well and the oil well in the water injection development process can be realized.

Description

technical field [0001] The present disclosure relates to the technical field of dynamic fracture geological modeling, and in particular to a permeability determination method, a characterization method and device, electronic equipment, and a storage medium. Background technique [0002] In general, reservoir fracture modeling techniques can be roughly divided into equivalent simulation method and entity fracture representation method. The former is an equivalent fracture probability model based on geostatistics. The simulation is carried out under the regular corner grid system, and only the matrix-fracture shape factor is calculated in a single corner grid. The fracture modeling results need to be quickly analyzed. Statistical coarsening is equivalent to reservoir simulation calculations, ignoring most of the fracture information; the latter uses discrete models or unstructured grid models to represent the local fracture characteristics of the model, and the results of thes...
