Study On The Development Evaluation And Potential Tapping Measures Of The Jinzhou South 25-1 Fractured Reservoir

The southern 25-1 fractured reservoir in Jinzhou is a large offshore oil field discovered in recent years.The Jinzhou Southern 25-1 buried hill fracture reservoir is formed in the Archean and has the characteristics of typical buried hill fracture reservoir.The fractures in reservoirs are widely developed and the heterogeneity is serious.The water content of some oil wells rises too fast during the water injection development,and the daily oil production declines seriously.The lack of detailed research on various types of reservoir development indicators,such as formation pressure,water content,etc..The study on the reasonable development of the reservoir is helpful to improve the understanding of buried hill fracture reservoir metamorphic rock and improve the recovery.Our research object is the reservoir.First,based on the first-hand production data,draw production curve,including the production gas oil ratio,water cut and daily oil production so that we can aquire valuable information on the reservoir production and analyze various kinds of factors on the influence degree of the reservoir development dynamic and then we establish a numerical simulation model,and then based on this model,according to the horizontal permeability and vertical permeability,oil production rate,water ratio and reservoir thickness 5 indexes such as single factor and multiple factors analysis,put forward to optimize the optimum recovery degree.Finally we provide severa kinds of possible subsequent exploration plans for the future production.We study the influence of gas well to all kinds of injection development indicators.
