Modeling method for identifying natural fracture using grading and classification quantitative identifier

Abstract

A modeling method for identifying a natural fracture using a grading and classification quantitative identifier is provided. The method includes constructing a wellbore natural fracture grading and classification quantitative identifier by means of the fusion of static and dynamic information and macroscopic and microscopic information. A spatial natural fracture grading and classification quantitative identifier is constructed by means of seismic attribute multi-level nested variable time window optimization, and completing accurate, reliable and rapid construction of a grading and classification three-dimensional network model of natural fractures using an identification result above and a grading and classification three-dimensional modeling method of natural fractures.
