本专家系统使理论知识和经验知识、物探资料和地质、地化资料等多种信息得到优化与充分利用。在本系统中,知识获取模型是根据油气预测实际过程中所使用的分解方法和综合方法建立的。知识表示模型涉及五部分:知识的分级表示、数据处理、方法的表示、控制知识的描述和不确定性的描述等。基于这一模型建立的圈闭油气预测系统包括知识库、数据库、推理机、推理部分和学习部分。这一专家系统具有一定特色,进行了一定效果的理论试算和实际验算。本文还应用圈闭油气专家系统对苏北盆地草舍构造进行验算。

The expert system enables the optimization and full application of multiple-informations such as thecretic and practical knowledges, geophysical, geolcgical and geochemical informations. The model of knowledge acquirement in the system is set up with the resolvent and generalization used during the process of practical prediction. Five parts are involed in the knowledge expression model, i.e: graded knowledge expression, data processing, method expression and descriptions of controlling knowledge and uncertainty. The expert system based on the model inclueds knowledge base, data base, reasoning and learning parts,which is capable of theoretic and practical computations. It is applied to check computations of Chacshe structure in Qingtong depression, north Jiangsu.

此项研究得到联合国029项目以及地质行业科学基金“灰色系统理论在地质中的应用”子课题的资助
