【摘要】 地质导向技术是根据地质导向工具提供的实时测量数据，用前导模拟软件进行大角度井、水平井钻井设计及指导钻井施工的一种综合方法。它能实时检测到地层变化以便及时对钻井设计做必要的调整，使钻头能最大限度保持在油层中钻进，在提高产层暴露程度、高效开发复杂油藏、节省钻井时间及提高采收率方面具有重要意义。该技术由地质导向工具和井场信息系统两大部分组成。井场信息系统的核心是前导模拟软件系统，它与地质导向工具一起成为地质导向的关键技术。文中根据国内首次引进的地质导向设备，对该技术首次进行了较为系统的介绍，并给出了综合应用实例，基本反应了地质导向技术的最新进展和发展趋势。该技术在断块油田中的应用具有广阔前景。更多还原

【Abstract】 According to real-time measurements of geosteering tool, Geosteering is an integrated approach to drilling high-angle and horizontal wells incorporating forward modeling into the overall planning and drilling phases. Geosteering allows real-time detection of geological changes and, in turn, allows effectively developing complex structure reservori, reducing drilling time and improving oil recovery. Geosteering includes geosteering tools and Wellsite Information System(WIS). Forward modeling software is a core techniqe of WIS. Forward modeling and geosteering tools are critical technique of Geosteering. This paper will give you a guideline of Geosteering referring to the first imported geosteering equipment in China and give yor an integrated applica tion example. This paper gives a basic discription of the latest situation and future trend of Geosteering. Geosteer ing promises good use in fault oil-field.更多还原
