人工智能地层对比专家系统原理

The Principle of artificial intelligence expert system for strata correlation.

将人工智能理论用于井间地层对比 ,设计开发出基于规则推理的人工智能地层对比专家系统。该系统应用句法分析完成了数字化测井曲线的符号化表示 ,建立起了一套完整的地层划分规则和地层对比规则。文中所述的方法能够很好地解决地层变薄 ,尖灭和缺失情况下的井间地层对比问题 ,应用实例说明了该方法的有效性。

Artificial intelligence expert system for strata correlation based on rule reasoning has been designed and developed.The system uses syntax analysis to finish the symbolic expression of digitizde log curves,and constructs a complete set of strata division and correlation rules.The method presented herein can well solve the crosswell strata correlation problem in circumstances of strata depth changing small,pinching out,and lacuna.Application examples say it effectiveness.
