Title: Method and system for damping vibrations in a tool string system
Inventor: SICCO DWARS
IPC: E21B44/00
Filed: 2015-09-15
Abstract: The invention provides a control system and method for limiting vibrations in a tool string system, comprising a relatively heavy rotatable device, such as a pump system or a bottom hole assembly, connected to an long rotatable tool string driven by a drive system. The control system comprises feedback of both torque and rotational speed signals to correct the set rotational speed. The method involves the damping of vibrations in a tool string, said vibrations comprising torsional waves propagating along said tool string, the method comprising the steps of: instructing a drive system (30) to rotate the tool string (12) at a set rotational speed (Ωr) ; determining a rotational speed (ωr) of the tool string (12) ; determining a torque (T) at or near the interface between the tool string (12) and the drive system (30); determining a tool string impedance ( ζ ) of a section of the tool string adjacent said interface; calculating a rotation correction signal (190) using the determined torque (T) multiplied by the determined tool string impedance ( ζ ) ;correcting the set rotational speed (Ωr) using the rotation correction signal (190) to provide a corrected set rotational speed (Ωr,cor) signal (170) ; subtracting the measured rotational speed (ωr) from the corrected set rotational speed signal (170) to provide a twice corrected set rotational speed (Ωr,2cor) signal (172) to the drive system (30) .

A J-slot arrangement in rotary part 114 with pin follower 112 controls axial engagement device displacement so the valve opens and closes as it moves in the same selected direction through an outer tubular 120 when the keys engage an internal profile 124. The J slot arrangement may be male or female on the housing and the biasing device may be a coiled compression spring or an extension, elastomer, gas or liquid spring. Alternatively (Fig. 13), the mandrel may be fixed and a valve body (96) may move with the engagement device and pin 110. May be used in a gravelling operation in a washpipe.

Title: CVT V-belt clamping
Inventor: MANOUSOS PATTAKOS
IPC: F16H61/662
Filed: 2017-09-04
Abstract: A V-belt CVT drive comprising a driving pulley and a driven pulley connected by a belt, wherein each pulley comprises two conical sections with opposed points which are axially movable with respect to each to each other. The springs which push the driven pulley to clamp the belt are variably or pivotally inclined with respect to the axis of the driven shaft, being inclined farther from the axial direction at a longer transmission ratio than at a shorter transmission ratio. This is in order to prevent over-clamping, and saves energy and material wear. The component of the force exerted by the spring in the axial direction is reduced as the conical sections move farther apart, reducing the clamping force when less clamping force is required. The spring housing may be subject to increasing inertial or centrifugal forces as the speed of the drive increases, and the springs may be provided in cartridges to mitigate the effects of these forces.
