摘要： Viscosity assemblies may be used to determine the viscosity of a sample fluid at a surface location under one or more downhole conditions prior to pumping or flowing of the sample fluid downhole. A viscosity assembly may include a bob assembly disposed in a container that includes a bob disposed about a magnet rotor that rotates when a shear force is applied by the flow of the sample fluid in the container. A stator coil may receive a control signal that induces a force or a voltage that causes the magnet rotor to rotate the bob by a predetermined distance to position the bob from the rotated position back to the initial position.

摘要： A directional drilling steering system is configured to direct a tubular sleeve arranged at the bottom of a drill string adjacent the drill bit at a selected tilt angle with respect to the longitudinal axis of the uphole drill string and at a selected azimuth. Tilt angle can be achieved by axial movement of one or more pistons in engagement with the downhole tubular sleeve. Azimuth can be achieved by axial movement of the pistons or by rotation of the drill string. The movement of the downhole sleeve along the deviated path causes movement of the drill bit shaft and the drill bit coupled thereto.

摘要： An assembly for inclusion between a drill bit and a drill string, the assembly having an overrunning clutch mechanism that disengages the drill bit from the drill string during the "slip" portion of a stick-slip cycle to allow the drill bit to freely rotate faster than the drill string. The assembly further includes a rotational vibration dampener operatively connected between the overrunning clutch and the drill bit. The vibration dampener may include a fluid chamber with viscous fluid or restrictions to fluid flow to effect dampening. During normal operation, the one-way overrunning clutch remains engaged to transfer torque between the drill string and bit, while the torsional damper is in its maximum displaced position to transfer the load. During slip, the drill bit is disengaged until its speed is lower than the drill string speed. Torsional vibration dampener dampens sudden impulse force of the overrunning clutch re-engaging.

摘要： Disclosed is a method of testing liquids at a test pressure. A first fluid is placed in a first chamber of a test system. The first fluid is brought to the test pressure. A volume is calculated of a second fluid to inject into the first chamber from a second chamber of the test system via a first portion connecting the first chamber and the second chamber. The first portion includes a fluid interface between the first fluid and the second fluid located in the first portion. The volume of the second fluid is injected into the first chamber, displacing an equivalent volume of fluid into a third chamber of the test system via a second portion connecting the first chamber and the third chamber in fluid communication with each other. The volume of the second fluid in the first chamber is mixed with a remaining volume of the first fluid in the first chamber to create a combination fluid. The combination fluid is tested.
