Evaluation of Hydraulic Properties on Wellbore Productivity-Based on Discrete Fracture Model

In the past few decades, multi-staged fracturing technologies applied to horizontal wells have significantly facilitated the development of oilfields. Nevertheless, a quantitative assessment of the complexity of the fracture network generated by hydraulic fracturing has been confronted with many difficulties. In this research, a discrete fracture model (DFM) based on computational fluid dynamics (CFD) was developed in a naturally fractured reservoir. In addition, hydraulic fracture aperture, hydraulic fracture numbers, and permeability on oil production rate were examined. A sensitivity analysis was conducted, and the results revealed that the oil production rate increased with increased fracture aperture and hydraulic fracture numbers. To validate the accuracy of the proposed method, a comparison between pressure distributions in a single fractured reservoir with a phase-field discrete fracture model (PFDFM) has been conducted. The proposed method for simulating fluid flow in a fractured porous medium is accurate, convergent, and very promising by numerical results
