Abstract: The operation of rotary equipment carried on elongate structure such as coiled tubing extending into a borehole from the Earth's surface is carried out by providing at least one optical fibre extending downhole to the rotary equipment from the surface, using optical time domain reflectometry to operating the optical fibre as a distributed vibration sensor while the rotary equipment is in operation, and thereby observing vibration created by the rotary equipment.

Abstract: Wear sensors are provided on a drill bit or other rotary cutting tool which is for operation in a subterranean borehole and has a plurality of separate cutters protruding from a support structure towards the material to be cut by the tool. The electrically operated sensing means are located at or coupled to a sensing point within a protrusion from the support structure. This sensing point is located within a protrusion such that attrition of at least one cutter to a partially worn state brings the protrusion into abrasive contact with the material being cut and attrition of the protrusion then exposes the sensing point to the material which is being cut by the tool and thereby brings about a detectable change, which may include damage to the sensor at the sensing point, indicative of wear. The tool includes means to communicate data from the sensing means to the surface.

Abstract translation: 磨损传感器设置在钻头或其他旋转切削工具上，该切削工具用于在地下钻孔中操作，并且具有多个单独的切割器，从支撑结构朝向被切割的材料突出。 电动感测装置位于或联接到来自支撑结构的突起内的感测点。 该感测点位于突出部内，使得至少一个切割器的磨损部分磨损的状态使得突起与被切割的材料磨蚀接触，然后使突起的磨损将感测点暴露于正被切割的材料 该工具并因此引起可检测的变化，其可能包括在感测点处损坏传感器，指示磨损。 该工具包括将数据从感测装置传送到表面的装置。
