Abstract
Based on finite element method, a complex fracture model of volume fracturing has been established for tight oil in this paper, which achieves the actual description of complex fractures. For water injection conditions, the volume of fractures network after fractured which considered the influence of fracture segment was analyzed by using numerical simulation. By comparing and analyzing the simulation results, the most optimal fracture segment is 10. The research results provide a theoretical basis for the optimized design of volume fracturing in tight oil. Key words: Tight oil; Volume fracturing; Numerical simulation; Finite element method
