摘要： The invention provides a method of detecting, at the surface, the occurrence of torsional vibration in a bottomhole assembly mounted on the drill string of a rotary drilling system. The method includes the steps of: ascertaining natural frequencies of torsional vibration of the bottomhole assembly prior to drilling, and noting at least one reference frequency for an integer wavelength mode of torsional vibration of the bottomhole assembly. During subsequent drilling, the drill string mean square torque at the surface is monitored for a bandwidth around the reference frequency. It is found that peaks in the mean square torque, close to the reference frequency, are indicative of the occurrence of torsional vibration in the bottomhole assembly.

摘要： An apparatus for magnetic resonance imaging is described having a casing with an inner bore which in some embodiments is substantially frustoconical shape for receiving a subject. The apparatus contains devices disposed in the casing to create a uniform field within an inner bore. The apparatus employs dual access since the inner bore has a first and second end at the outer edge of the casing for which the part of the subject's body would travel so as to be imaged. Further, in some embodiments, the apparatus provides one or more recesses for inserting at least one gradient coils into position about an inner bore. The MRI system induces resonance in selected dipoles in an examination region created along an inner bore of a casing housing in a magnetic resonance imaging system such that the selected dipoles generate magnetic resonance signals to create an image representation of the part of the subject's body.

摘要： A torque transmitting device for use with a rotary drill bit connected to a drill collar, comprises a first member connected to the drill collar, a second member connected to the drill bit, and coupling means connecting the two members together for rotation about a common central axis. The coupling means permits limited relative rotation between the members about the axis, but provides a resistance to rotation of the first member relative to the second member in a forward drilling direction which is greater than its resistance to relative rotation in the reverse direction. The comparatively lower resistance to rotation in the reverse direction prevents momentary reverse rotation of the drill collar, due for example to torsional oscillations, being transmitted to the drill. bit. This reduces the likelihood of damage to the cutters on the drill bit, which might otherwise result from such momentary reverse rotation of the bit.

摘要： Disclosed is a method of comparing the relative lateral stability among drill bits (that is, the tendency for a bit to whirl). This allows improved bit selection in applications where whirl is apparent. Because there will likely be many different acceptable bit designs produced by the above method, the comparison of the regenerative forces among these bits allows a customer to make a more informed choice between stability and other performance features among a range of bit designs.
