摘　　要：如何在有限资金下针对不同勘探目标进行评价优选是油气勘探者持之以恒的研究主题。不同勘探阶段油气勘探的目的不同,勘探对象也有所不同,其评价方法及参数也会有所差异。对比国内外相关评价方法,提出利用勘探程度指数作为划分勘探程度的定量指标,并结合不同勘探阶段我国油气勘探中主要面对的勘探对象,分别针对区块、区带、圈闭等不同类型的勘探目标开展了系统分析和方法参数研究,相应建立了不同勘探阶段下区块的"油气条件概率-资源战略价值"、区带的"油气发现概率-资源战略价值"和圈闭的"含油气概率-资源战略价值"等双因素评价优选模型,并开发具有自主知识产权及适应我国油气勘探的目标评价与优选系统,以满足勘探评价人员和管理人员客观、快速评价决策的需要。Evaluation and selection of potential exploration targets with limited capital support is an eternal theme for all the oil and gas explorers. Different exploration targets have to be dealt with in different stages of exploration,which means different evaluation methods and parameters. Based on a comparison of evaluation method both domestic and abroad,we proposed in this paper to quantitatively guide exploration with exploration extent index,and established several two-factor evaluation models（ hydrocarbon accumulation conditions-resource strategic value model for blocks,hydrocarbon discovery probability-resource strategic value model for plays and hydrocarbon-bearing probability-resource strategic value model for traps） with intellectual property for different stages of exploration based on systematic analyses and parameters selection upon various exploration targets such as blocks,plays,traps and etc. The models are customized for oil and gas exploration in China and can be used to yield objective and quick evaluation and selection results for explorers and management staff.
