摘要: 提出了在基本评价单元划分的基础上进行分类评价、优选排队、风险分析、经济评价的一整套未动用储量评价方法,主要应用模糊数学方法对未动用储量评价单元进行分类评价和优选排队,应用蒙特卡洛方法评价未动用储量评价单元投入开发的地质风险和经济风险。该方法综合考虑油藏的地质、油藏、技术、资料、经济、风险等因素的影响,符合油田的实际情况,在大庆外围油田的实际应用中取得了较好的效果。

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
