Abstract: A large number of experimental studies have shown that long-term flow conductivity of artificial fracture
changes over time. So this paper establishes mathematical model of percolation in the condition that the long-term
flow conductivity of the artificial fracture alters over time. By numerical simulation， this paper states about the
impacts of change of the long term flow conductivity on the production and flow field. The results show that the
loss of the flow conductivity will lead more formation fluid to the bottom of well through the fracture near the
bottom， which makes the flow field in the fracture reasonable and slows down the decreases of productivity. When
other conditions are same， the longer the fracture is， the more impact the lost of the flow conductivity has on the
productivity.

Key words: water fracturing, flow conduction, numerical simulation, flow field, production performance
