The Evaluation Research Of Develops Effect In Lamadian Oilfield

This paper were evaluated develops effect of LAMADIAN Oilfield, It reveals principal contradiction on development process of LAMADIAN Oilfield,It defined the potentiality of the Oilfield and analyzed the producer-injector structural,the waterflood pattern,the rational of layer division and combination After ultra-high water cut phase in LAMADIAN Oilfield.This paper have researched water cut increasing rate and natural decline rate of oil reservoir water drive,Evaluated the develops effictiveness in LAMADIAN Oilfield.Proved it had reached a high level in water drive reserves and the production of development reserves during development process of LAMADIAN Oilfield.Analyzed the adaptability of producer-injector structural and the waterflood pattern, that had reached a high level about areal sweep efficiency and abundance of oil layer, that is necessary subdivision developed to solve the problem of big difference of permeability and serious interlayer interference.This Research have a definite directive significance for keep relatively long-term production stable in LAMADIAN Oilfield.
