Abstract: To produce those reserves with low quality, low benifit and difficult to produce, a set of effective evaluation methods are needed. In the past, only geologic and reservoir factors are considered in nonproducing reserves evaluation, far from meeting the real requirements. A set of evaluation methods are put forward for nonproducing reserves,including the classified evaluation and optimized queuing for basic evaluation units of nonproducing reserves by applying fuzzy mathematical method, geological risk and economic evaluation for nonproducing reserves evaluation units if brought into development. Some factors such as geology, reservoir, technology, data, economics and risk are considered comprehensively in this method, matching the practical situation of oilfield. A favorable effect has been achieved in practical application in Daqing peripheral oilfields.

Key words: reserves, classified evaluation, economic evaluation, risk analysis, fuzzy comprehensive judgment
