| 摘 要： | 在详细研究岩、电关系的基础上,将专家系统有关原理应用于测井分析中,导致了复杂砂、泥岩测井相专家系统的产生。该系统以框架结构表达知识,使用产生式规则,依据对测井资料进行处理而提取的各种信息进行推理、分层,逐级产生详细的岩性分类结果,并结合曲线形态与泥质含量分析等信息,最终得到沉积相的分析结果。经对尕斯库勒油田E31沉积相进行解释,表明该系统具有一定的应用与推广价值。

| Abstract: | This paper introduces the design idea,main functions and structure of an expert system in well-log fades analysis of a complet sand-mudstone. In addition,a detailed discussion on the principle of inference its and application characteristics is presented. The system is programmed with C language &. 8086/80286 Assemble Language. On the basis of a deep study on the electric-lithologie relationship and the electric-ithofacies relationship,we apply the relevant principles to well-log fades interpretation,which gives rise to a successful system. Abundant functions,consisting mainly of pretreatment,knowledge acqmsition,fact rule management,inference,explanation and so on,are included in the system. |
