Abstract
Methods and systems are provided for monitoring operational characteristics of a drilling system that includes a bottom hole assembly having a drill collar operably coupled to a drill bit. A device having an elongate beam and at least one pair of sensors is rigidly secured to a part of the bottom hole assembly to measure strain in the part of the bottom hole assembly. The measurement of strain can be used to derive a measurement of at least one operational parameter of the drilling system, such as dog leg severity of a wellbore, torque on bit, and/or weight on bit.
Claims16
A drilling system comprising:
- a bottom hole assembly having a drill collar operably coupled to a drill bit;
- and
- a strain measurement device connected to the drill collar, wherein the strain measurement device comprises:
- a first end and a second end and an elongated central beam disposed between the first end and the second end, the first end and the second end having a plurality of attachment points, wherein each of the first end and the second end has a thin portion and a raised portion, and wherein the raised portion is configured to connect to the elongated central beam, and
- a plurality of strain sensors attached to the elongated central beam, wherein at least a first of the plurality of strain sensors is configured to measure torque on the strain measurement device, at least a second of the plurality of strain sensors is configured to measure load on the strain measurement device, and at least a third of the plurality of strain sensors is configured to measure bending on the strain measurement device.
