Abstract: The producing mechanism in igneous reservoir is a no dus.Based on the simulation dual media model formation pa-rameters have some effect on primary producing by singular and multi-factors.The result shows that valid permeability at fracture is the most important and the permeability at ma trix.is the least meanwhile the variation trend to production index is obtained impacted by permeability and porosity at fracture and matrix,respectively.The study implies that the adjustment method is simple and valid for next stage of matc-hing history.
