    • Integrated drilling and evaluation systems and methods for drilling, logging and testing wells are provided. The drilling and evaluation systems are basically comprised of a drill string, a drill bit carried on a lower end of the drill string for drilling a well bore, logging while drilling means included in the drill string for identifying subsurface zones or formations of interest, packer means carried on the drill string above the drill bit for sealing a zone or formation of interest below the packer means, and a fluid testing means included in the drill string for controlling the flow of well fluid from the zone or formation of interest into the drill string. The drilling and evaluation systems and methods for using the systems allow one or more subsurface zones or formations of interest in a well to be drilled, logged and tested without the necessity of removing the drill string from the well.
    • 提供了钻井,测井和测井综合钻井和评估系统和方法。 钻井和评估系统基本上包括钻柱,用于钻井的钻柱的下端承载的钻头,包括在钻柱中的钻孔装置的记录,用于识别感兴趣的地下区域或地层,封隔器 在钻头上方的钻柱承载的装置,用于密封封隔器装置下方的区域或形成层,以及包括在钻柱中的流体测试装置,用于控制井流体从所述区域或形成物流入钻头 串。 用于使用系统的钻井和评估系统和方法允许钻井,记录和测试中的一个或多个感兴趣的地下区域或地层,而不需要从井中移除钻柱。
