    摘要: A method of assaying work of an earth boring bit of a given size and design comprises the steps of drilling a hole with the bit from an initial point to a terminal point. A plurality of electrical incremental actual force signals are generated, each corresponding to a force of the bit over a respective increment of the distance between the initial and terminal points. A plurality of electrical incremental distance signals are also generated, each corresponding to the length of the increment for a respective one of the incremental actual force signals. The incremental actual force signals and the incremental distance signals are processed to produce a value corresponding to the total work done by the bit in drilling from the initial point to the terminal point. Using such a basic work assay, a number of other downhole occurrences and/or conditions can be assayed. These include a wear rating for the type of bit, a determination of whether such a bit can drill a given interval of formation, and assessment of the abrasivity of rock drilled (which in turn can be used to modify the assays of other conditions and/or occurrences), a model of the wear of such a bit in current use, and a determination of the mechanical efficiency of the bit.

    摘要: A method and apparatus are provided for drilling a borehole through formations of the earth to a targeted position relative to the entrance of the borehole on the surface of the earth. At each measurement of the position and orientation of the downhole drilling mechanism, the system controller determines a new optimum path to the target and commands the drilling apparatus to produce this optimum path. Different criteria may determine the optimum path. The preferred criterion is the path of minimum tortuosity.
