Abstract: Based upon the hierarchy and integration natures of trap assessments,a new method using ES theory to imitate geology experts is presented.The reasoning networks and models to assess source rock drainage,reservoir rock properties,cap rock sealing capabilities,fault sealing capabilities and preservation conditions are established.Combining these factors,the integrative assessment models for different type of traps are formed,and a trap assessment system is built up by converting all models into computer programs.

Key words: trap assessment, expert system, model, reasonging network

摘要： 根据圈闭地质评价过程具有层次性和综合性的特点,应用专家系统方法模拟专家评价过程,建立了圈闭供油条件、储集条件、盖层封闭性、断层封闭性、油气保存条件评价的推理网络和评价模型,在此基础上建立了不同类型圈闭的地质综合评价模型及评价系统.
