摘要/Abstract

摘要： 随着勘探的不断深入，勘探目标评价已由盆地评价逐渐转移到以区带和圈闭为主的目标评价上。作为油气发现的主要勘探目标，预探区带是实现效益勘探的重点目标。油气预探区带评价存在勘探程度低、评价参数多并难以量化等问题。基于勘探风险分析技术建立了“油气发现概率-资源战略价值”的预探区带评价模板，提出了对应的评价参数、赋值标准、计算公式及结果分类标准，实现了统一平台下的预探区带评价优选。利用该方法对四川盆地通南巴、鄂西-渝东、南江和川东南下组合及知新场-龙宝梁陆相等油气预探区带进行了评价优选，指出了重点勘探方向。

关键词: 评价模型, 资源战略价值, 油气发现概率, 区带评价, 预探区带

Abstract: With the increasing of exploration maturity,the focus of exploration target evaluation has gradually shifted from basins to plays and traps.As the major targets to hydrocarbon discovery,preliminary exploratory plays are the main targets to achieve exploration benefit.However,evaluation of preliminary exploration target is very challenging due to the low exploration maturity and multiple evaluation parameters which are difficult to quantify.Based on the principles of exploration risk analysis,this paper established the model of probability of hydrocarbon discovery-strategic value of resources for evaluation of preliminary exploratory plays,and provided relevant assessment parameters,assignment criteria,computational formula and results classification methods,making it possible to evaluate preliminary exploration target on an unified platform.Five preliminary exploration plays in the Sichuan Basin,such as Tongnanba,Exi-Yudong,Nanjiang,lower combination of southeast Sichuan and Zhixinchang-Longbaoliang,are selected and evaluated with this model.

Key words: evaluation model, strategic value of resources, probability of discovery, play evaluation, preliminary exploratory play
