Abstract: The geological complexity of the proved non-producing reserves resulted in the difficulty of its exploitation technique and economic evaluation.Accordingly, two basic problems would be faced at the time of evaluation:one is evaluation criterion, the other is evaluation method.Based on typical study, multistage evaluation criterion of seven parameters and three factors about the quantity, quality and production difficulty (quasiecnomic) of the reserves is proposed in this paper.The seven parameters are reservoir control degree, permeability, burial depth, reserves amount, reserves richness, mobility and degree of reaching the productivity standard.At the same time, by combining the theory of Gray System Theory correlation degree with the characteristics of the proved non-producing reserves, multistage comprehensive gray evaluation is proposed, which makes the reseves exploitable scale per estimation unit (block) be quantitated by computer programming and processing.It is confirmed by practice that this method is an effective and practical new multistage comprehensive estimate one with good economical and social benefits.
