摘要： A rotational driveshaft coupler that converts a rotating shaft motion into two orthogonal oscillations and at the opposite side of this coupler, a third oscillator converts the oscillations back to a rotational motion. At least one slip free seal can be constructed from the coupler to its housing to separate the space occupied by the output shaft from the space occupied by the input shaft. Each of the three oscillating motions can be guided by bearings, gears and tracks to reduce frictions and heat generation. Permanent magnet pairs are used to prevent bifurcation and force the output shaft to follow the rotation direction of the input shaft. Unlike in magnetic coupling, the torque transmission here is direct.

摘要： Methods and related systems are described making seismic measurements. Seismic energy is transmitted into the earth using a surface seismic source. The seismic energy is received with one or more downhole receivers located in a borehole. In response to the received seismic energy from the surface seismic source, seismic energy is transmitted into the earth using a downhole seismic source. The seismic energy from the downhole seismic source is then received with one or more surface receivers located on the surface of the earth. A delay interval is measured downhole between the first arrival of the seismic energy from the surface seismic source and the transmission from the downhole seismic source. A surface interval is measured between the transmitting of seismic energy from the surface seismic source and first arrival of the seismic energy from the downhole seismic source using the one or more surface receivers. Travel time can be calculated by subtracting the delay interval from the surface interval.

摘要： Elastodynamic waves are generated by a tool having a hammer rotatably connected with a housing by a first hinge and an actuator arm rotatably connected with the hammer by a second hinge. An axial force applied to the actuator arm by a drive shaft and spring is translated and amplified to a radial impact force by rotation of the hammer around the first hinge. The tool may also include a stabilizer arm connected to the actuator arm by a third hinge, and connected to the housing by a fourth hinge. The housing may be an acoustic wireline tool cylinder having an opening that permits the hammer mass to extend outside the housing when rotated in a first direction. The housing may also include a second opening that permits the hammer mass to extend outside the housing when rotated in a second direction, and a third opening that permits the hammer mass to extend outside the housing when rotated between the first and second openings.
