ROGUE Borehole Televiewer data

These data are borehole logs using an Optical Televiewer in a hot-water drilled borehole. The televiewer creates 360-degree 'unwrapped' image of the borehole wall as it descends through the hole. In addition to the image log, the televiewer also measured the inclination, azimuth, and temperature of the imaging head, as well as the strength of the magnetic field and gravity. For each log, there is thus a bmp file which is the image iteslf, and a csv file which is the ancillary information, including the depth registration information for the image.

本数据集为热水钻井钻孔中使用光学声波电视（Optical Televiewer）获取的钻孔测井数据。该设备在沿钻孔向下移动的过程中，可生成钻孔井壁的360度"展开式"图像。除成像测井数据外，光学声波电视还同步采集了成像探头的倾角、方位角与温度，以及磁场强度与重力场强度数据。针对每一组测井数据，均配套两类文件：其一为存储井壁成像的BMP格式图像文件，其二为包含辅助信息的CSV格式文件，其中辅助信息涵盖该图像的深度标定相关信息。
