发明名称 Remote sensing and measurement of distances along a borehole
摘要 A borehole probe and related method and apparatus that enables information related to the depth of the probe to be determined and utilized by the probe to perform tasks. The probe, comparing its sense of depth and other sensed physical and temporal information to pre-defined procedural and conditional constraints, causes a physical action to be performed, or signals another device, or signals the surface. Generally, the probe uses sensed benchmarks within the borehole that have an associated depth as a depth framework. Within the distances between the benchmarks, the probe uses inertial or other distance measuring devices to measure distance from the benchmarks. With accurate and constant knowledge of its own depth, the probe can perform tasks autonomously and at the correct depth.
