摘要
简要介绍了电磁波电阻率(EWR)的结构和工作原理,分析了电磁波电阻率探测深度的影响因素,以两口井为例,介绍了EWR在水平井井眼轨迹控制中的应用情况。利用EWR的实时电阻率曲线可以较好地控制井眼轨迹沿油层最佳位置钻进,从而提高油层采收率和单井产量,而且它可以实现地层的实时评价,避免由于地层情况不明、设计出现误差而找不到油层、填井报废等事故的发生。
This paper presents the structures and working principles of EWR ,analyzes factors that influence investigation depth of EWR. Giving two wells as examples, horizontal well trajectory control by EWR are presented. Trajectory can be controlled along optimum location in oil reservoirs by EWR in real time. According to this, reservoir recovery rate and individualwell producing rate can be improved, formation evaluation can be made in real time, accidents that the well have to be filled for losing oil reservoir can be avoided.
