综合录井在安全钻井中的应用及发展趋势

The application and development trend of comprehensive mud logging technology in safety drilling

针对目前国内钻井事故检测、预报技术存在的检测手段少、自动化、智能化程度低和检删技术理论不系统等现状,在调研分析国内外综合录井发展及应用现状的基础上,提出了可借鉴国外的经验,检测仪器研发的重点向井下转移；在地面参数检测方面,以综合录井信息为基础,利用故障检测与诊断的相关理论开发钻井故障检测和诊断系统与方法。综述了国外井下测量系统的特点及应用情况,对我国综合录井的发展方向进行探讨。

In view of the present domestic situation that the tech- niques of detecting and forecasting drilling accidents are few,their automatic and intellectualized extent is low and the theory of surveying technique is not systematic.On the basis of investigation,studying and analyzing the compre- hensive mud logging developing and current applied situa- tion at home and abroad,the paper put forward the foreign experiences which can be used for reference,and pointed out that the key points of studying and developing detection instrument had been shifted to downhole.As for surface pa- rameters monitoring,drilling fault detecting and diagnosing system and methods were developed based on comprehen- sive mud logging information with the related fault detecting and diagnosis theory.The paper also summarized the fea- tures and application situation of the foreign downhole measuring system and made a discussion of the developing direction on the home comprehensive mud logging .
