Study on oil-water interface of Budate fracture reservoir in each block of Suderte Oilfield

It is well known that in addition to bound water the reservoir, formation mainly exists form of edge and bottom water. Fractured buried hill metamorphic rock reservoirs are generally bottom-water reservoirs. In fractured reservoirs, blocks cut by fractures oil distributed fractures. Due low capillary pressure fractures, oil-water transition zone also small. same fault block, there relatively uniform interface. And interface judge correctly or not will directly related determination oil-bearing area effective thickness division placement, thus determine position field development great significance, through variation presumably some guidance on seismic section can't precisely divide small fault.
