The Visualization of 3D Geometry of the Fractures Around Wellbore Underground

Due to its unobservability, randomness and staggered complexity, we cannot well understand the real form and distribution of the natural fracture of the rock in the deep strata, leading to a series of construction problems in the exploration and development of oil. At present, the geometry of fractures is displayed by the form of two-dimensional graph or data table, which cannot be performed more visually. In light of this finding, through the data analysis of fractures collected from the engineering practice, using the Monte Carlo method and a variety of programming languages, this paper has performed three-dimensional visualization of macroscopic fractures around wellbore underground. The data collected from Keshen block in Tarim oil field is simulatedand its results show that the simulation of the three-dimensional geometry of the fractures has achieved a good visual effect and provided a visualization of platform for further research such as wellbore stability about fractureformation.
