The Ordovician of Tazhong I Gasfield belongs to carbonate condensate gas reservoir dominated by the development of fracture and cave.The reservoir types can be divided into crack-hole,cave,hole and fracture.Geological research and dynamic production indicate that the reservoir has strong heterogeneity,complex gas-water relationship.Part of the test wells are affected by formation water seriously,and gas production of different reservoirs show great differences.Further research is required to find out the decreasing rule of different reservoirs.Therefore,prediction and planning can be made for the oil/gas production to increase the economic benefits.
