Abstract:

Fluidsolid coupling is used to consider the stresssensitivity in simulation,but it needs a lot data and computing time as the progress of simulation will be impacted.Introducing the poroelasticity and double effective stress theory,the authors of this paper get the relationship of the fluid pressure and the permeability,and the laboratory data is transformed to the insitu data.The relationship ia applicated in the simulation,the results show that the reduction of accumulative production and days of stable production resulting from stresssensitivity is small; and the difference of simplified model and fluidsolid coupling model is small.

Key words: stresssensitivity, fluidsolid coupling, permeability, double effective stress, numerical simulation, simulator 
