综合录井实时异常压力预测专家系统的研究

A Real-time Expert System for Abnormal Pressure Prediction with Mudlogging

运用实时专家系统的方法来预测因异常压力引发的几种井下复杂情况的早期表现，并给出处理的建议和措施。所建立的异常压力预测专家系统是一个基于模糊理论和产生式规则的专家系统，不仅具有实时识别的功能，而且还具有显示实时数据的能力；它属于钻井安全专家系统的范畴。

Abnormal pressure prediction is a difficult problem which has confused drilling field for a long time.By predicting abnormal pressure accurately,not only can it provide security environment, but also protect oil andgas resouces efficiently. The purpose of this paper is to detect the early portent of some accidents resulted from abnormal pressure and to provide the suggestions and measurements through setting up real--time expert systembased on fuzzy theory and production rules. In addition to the function of real-time expert system,the system hasthe capacity of displaying real-time data.It is in the field of wellsafe expert system.
