    Abstract
  • The 2 fields of fluid flowing and stress simultaneously play roles in the pore-fracture media(during) hydrocarbon exploration.The coupling effects may change the reservoir formation parameters and affect the liquid distribution.Therefore,it is necessary to utilize a liquid/solid couple model to analyze the fluid flowing behavior in double porosity media.This model has been made thanks to the concept of effective stress.Finite Element Method and limited difference are utilized to gain solutions.The influence of couple effect on accumulation is stated as follow: higher pressure coefficient,poorer formation nature,and more remarkable liquid/solid couple effects.The effect will gradually disappear as the development time prolongs,therefore,it is not necessary to take into account the liquid/solid couple effects in all double porosity media reservoirs.
