Abstract EN
This study develops a mathematical model for transient flow analysis of acid fracturing wells in fractured-vuggy carbonate reservoirs.
This model considers a composite system with the inner region containing finite number of artificial fractures and wormholes and the outer region showing a triple-porosity medium.
Both analytical and numerical solutions are derived in this work, and the comparison between two solutions verifies the model accurately.
Flow behavior is analyzed thoroughly by examining the standard log-log type curves.
Flow in this composite system can be divided into six or eight main flow regimes comprehensively.
Three or two characteristic V-shaped segments can be observed on pressure derivative curves.
Each V-shaped segment corresponds to a specific flow regime.
One or two of the V-shaped segments may be absent in particular cases.
Effects of interregional diffusivity ratio and interregional conductivity ratio on transient responses are strong in the early-flow period.
The shape and position of type curves are also influenced by interporosity coefficients, storativity ratios, and reservoir radius significantly.
Finally, we show the differences between our model and the similar model with single fracture or without acid fracturing and further investigate the pseudo-skin factor caused by acid fracturing.
