基于现场总线的生产井录井仪及其专家系统

A Logging Instrument and Expert System Used in the Production Well Based on Field Bus

随着钻井生产由粗放钻井向精细钻井的发展和油气开发的决策需要 ,必须配备生产井录井仪 ,对生产井的钻井过程进行全过程监测和录井信息评价。针对生产井钻井过程的特点 ,设计研制了基于现场总线的小型化、配置灵活、功能开放 ,成本较低的油气田生产井录井仪及其专家系统。现场应用表明 ,研制开发的软硬件系统不仅能够为生产井的精细钻井和录井信息评价提供准确齐全的钻井参数 ,同时 ,设计开发的录井专家系统还能够实时准确地对钻井过程进行状态判断 ,实现了指导钻井的目的。

With the development from rough drilling to fine drilling in the drilling engineering and because of need of the decision-making on oil and gas exploitation, it is necessary for logging instrument of production well to be used in drilling process of production well so as to monitor the total drilling and to evaluate the logging information. A logging instrument of production well was developed based on field bus according to the features of drilling process of production well. It has the characteristics of miniaturization, flexible configuration, comprehensive function and low cost. It has practically been proved that all kind of data can not only be accurately obtained to serve the evaluation to logging information and the fine drilling by using the developed system, but various real time status can be also accurately distinguished by logging expert system to supervise the drilling operation.
