使用配有倾斜天线回路的旋转工具确定地层参数的方法和系统

Methods and systems for determining formation parameters using a rotating tool equipped with tilted antenna loops
Abstract:
Methods and systems for characterizing a formation are disclosed. A tool is placed in the formation. The tool comprises a perpendicular antenna set and a parallel antenna set. The perpendicular antenna set comprises at least one transmitter antenna oriented perpendicular to at least one receiver antenna and the parallel antenna set comprises at least one transmitter antenna oriented parallel to at least one receiver antenna. Data is obtained from the tool and used to determine a compensated geosignal for each of the perpendicular antenna set and the parallel antenna set. The determined compensated geosignal is used to characterize the formation.
Abstract(Chinese):

公开了用于表征地层的方法和系统。 工具被放置在地层中。 该工具包括垂直天线组和平行天线组。 垂直天线组包括垂直于至少一个接收机天线定向的至少一个发射机天线，并且所述并行天线组包括平行于至少一个接收机天线定向的至少一个发射机天线。 从工具获得数据，用于确定每个垂直天线组和平行天线组的补偿地理信号。 确定的补偿地质信号用于表征地层。
