油气勘探目标经济评价与决策系统EDSys1.0

油气勘探目标经济评价与决策系统EDSys1．0包括3个部分：①数据处理与管理部分，既是提取被评价目标地质评价结果、资源量评价结果等外部基础参数的工具，也是进行经济评价与决策分析的基础，包括对基础数据、通用参数的管理和测算勘探投资、开发投资、其他投资、成本费用等内容；②经济评价部分，是进行经济评价的核心技术模块，包括财务评价、盈亏平衡分析、敏感性分析、概率分析、极限经济指标估算等功能；③决策分析部分，用于勘探开发决策分析，包括单目标多方案优选、多目标优选、优化投资组合等功能。应用EDSys1．0系统能够更好地进行目标优选，使投资组合达到最优化，从而为勘探开发部署提供决策依据。图3表1参10

Economic Evaluation and Decision System of Petroleum Exploration Targets (EDSys1.0)

The Economic Evaluation and Decision System of Petroleum Exploration Targets(EDSys1.0) includes 3 models.(1) Data processing and managing model.It is the tool for selecting basic parameters such as target geological evaluationresults and resource evaluation results,and also the basis for economic evaluation and decision-making analysis.It has the functions of managing base data and common parameters,assessing exploration invest,developments invest and other invests,as well as calculating projects cost.(2) Economic model.It is the core model of the system,and covers financial evaluation,breakeven analysis,sensitivity analysis,probability analysis,and economic critical value assessment.(3) Decision model,used for decision-making analysis on exploration and development activities.It consists of 3 sub-models: single target,multi-designs optimization,multi-targets optimization,and invest portfolio optimization.This system can help a better optimization for exploration targets selection,and a better optimization for invest portfolio.The results can provide basis for decision-making on exploration and development activities.
