摘要： An improved method of drilling a substantially lateral section of a wellbore is provided. A first segment of a drilling string with a bottom hole assembly is extended into a wellbore. At determined intervals of the drilling string, a plurality of friction reduction segments are connected as the wellbore is drilled and the drilling string is extended into the wellbore. The friction reduction segments comprise a friction reduction tool and corresponding activation tool for activating the friction reduction tool. The activation tool selectively diverts drilling fluid into a motor powering the friction reduction tool or away from the motor, and can be a ball catch assembly that is activated when a suitably sized projectile is seated in the assembly. Multiple friction reduction segments can be connected to the drilling string and one or more of the plurality of segments can be activated.

摘要： A friction reduction tool and assembly are selectively activatable to produce fluid pressure pulses in downhole operations. The assembly includes a variable choke assembly having a rotary component and a stationary component, each with passages that enter into and out of alignment when the rotary component rotates with respect to the stationary component when driven by a rotor. The rotary component, stationary component, and rotor each have a central bore defining a central passage permitting fluid flow from above the assembly to below the assembly.

摘要： A flow-through assembly for use in a downhole drilling string includes a Moineau-type motor, means for selectively activating the motor such as a ball catch component that selectively causes drilling fluid to enter into or bypass the motor, and a rotating variable choke assembly that is driven by a rotor of the motor. The choke assembly varies the flow rate of drilling fluid as rotation causes ports of the choke assembly to enter into and out of alignment with each other. In one embodiment, the choke assembly comprises a faceted rotary component including bypass ports on the facets of the component. In another embodiment, the choke assembly comprises a tapered rotary component that rotates in a complementarily tapered stationary component.

摘要： A joint assembly for use in transmitting torque comprises a ball and socket arrangement. The socket is comprised in a housing, and further comprises a key chamber with a substantially regular polygonal profile defining interior faces. The ball is provided on a ball stud component, and has a plurality of convexly curved facets. The ball is inserted in the socket with a plurality of keys, such that the keys are disposed between the ball facets and a corresponding interior face. Each key provides a bearing surface that mates with a corresponding facet, and a surface opposite the bearing surface to mate with the interior face. The sides of the key define a biconvex profile.

摘要： A downhole assembly and method are provided for selective activation of a motor in a drilling string. A rotor in a Moineau-principle motor is provided with a fluid passage therethrough and a catch that can receive and retain a blocking implement. A driveshaft is operably connected, for example using universal joints, to the rotor and a first valve component. The driveshaft is effectively supported by a thrust transmission assembly comprising a thrust unit and hanger resting on a spring so that the first valve component is not in contact with a second valve component. When a blocking implement is in place, drilling fluid activates the motor and also increases pressure on the rotor, causing the thrust transmission assembly to move the first valve component down into contact with the second valve component.
