Fine Description Of Reservoir And Residual Oil Distribution In The Lower Es₂ Reservoir In The South Area

According to the characteristic of the lower Sha 2 reservoir in Block nanqu . this paper subdivides the flow units . It uses reservoir fine geologic description technique to study the micro structure and reservoir sedimentary micro-phase and construct a 3D model of reservoir structure,sand body and reservoir property . Through a comprehensive analysis on various dynamic monitoring data and a large amount of fine numerical simulation study of dense grid,it makes clear the residual oil distribution . Then it proposes and performs reservoir development adjustment measures to increase oil production and decrease water cut so as to improve oil recovery .I have formed a set of perfect multi-oil layer reservoir mobile unit division, the contrast, the forecast, the appraisal and application set of technologies through two years attack.This set of technologies in the mobile unit classification method, the nature explained technical, the multi-method mobile unit space forecast aspects and so on method, based on mobile unit plane distribution assessment method, remaining oil distribution has obtained the innovation and the breakthrough, for contained water the oil field development to provide the technical support high, tapped latent potentialities to the similar oil deposit has the important guiding sense.
