Under the new pat-tern, the economic evaluation, which is indispensable to the whole reservoir management system,provides scientific basis for
reaching the goals of optimizing fielddevelopment scheme,im-proving economic profits and reducing investment risk.On the basis of the study,the patterns and analytical methods of the e-conomic evaluation corresponding with the reservoir manage-ment have been put forward.
